ADDENDUM
This Addendum contains information that relates to the F35 Multiple Feeder Management Relay relay, version 4.9x.
This addendum lists a number of information items that appear in the instruction manual GEK-113205A (revision M2)
but are not included in the current F35 operations.
The following functions/items are not yet available with the current version of the F35 relay:
• N/A
Version 4.0x and higher releases of the F35 relay includes new hardware (CPU and CT/VT modules).
• The new CPU modules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, and 9R.
• The new CT/VT modules are specified with the following order codes: 8F, 8G, 8H, 8J.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:

MODULE OLD NEW DESCRIPTION

CPU 9A 9E RS485 and RS485 (Modbus RTU, DNP)
9C 9G RS485 and 10Base-F (Ethernet, Modbus TCP/IP, DNP)
9D 9H RS485 and redundant 10Base-F (Ethernet, Modbus TCP/IP, DNP)
-- 9J RS485 and multi-mode ST 100Base-FX
-- 9K RS485 and multi-mode ST redundant 100Base-FX
-- 9L RS485 and single mode SC 100Base-FX
-- 9M RS485 and single mode SC redundant 100Base-FX
-- 9N RS485 and 10/100Base-T
-- 9P RS485 and single mode ST 100Base-FX
-- 9R RS485 and single mode ST redundant 100Base-FX
CT/VT 8A 8F Standard 4CT/4VT
8B 8G Sensitive Ground 4CT/4VT
8C 8H Standard 8CT
8D 8J Sensitive Ground 8CT/8VT

The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R), and the old CT/
VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mismatches, the new
CPU and CT/VT modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and DSP module label
colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module, the relay will not
function and a DSP ERROR or HARDWARE MISMATCH error will be displayed.
All other input/output modules are compatible with the new hardware.
With respect to the firmware, firmware versions 4.0x and higher are only compatible with the new CPU and CT/VT mod-
ules. Previous versions of the firmware (3.4x and earlier) are only compatible with the older CPU and CT/VT modules.

 1.2 UR OVERVIEW 1 GETTING STARTED

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR

1 Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This
first generation of equipment was gradually replaced by analog electronic equipment, most of which emulated the single-
function approach of their electromechanical precursors. Both of these technologies required expensive cabling and auxil-
iary equipment to produce functioning systems.
Recently, digital electronic equipment has begun to provide protection, control, and metering functions. Initially, this equip-
ment was either single function or had very limited multi-function capability, and did not significantly reduce the cabling and
auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing cabling and aux-
iliaries significantly. These devices also transfer data to central control facilities and Human Machine Interfaces using elec-
tronic communications. The functions performed by these products have become so broad that many users now prefer the
term IED (Intelligent Electronic Device).
It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further
reduced, to 20% to 70% of the levels common in 1990, to achieve large cost reductions. This requires placing even more
functions within the IEDs.
Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and
as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to
perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.
High speed communications are required to meet the data transfer rates required by modern automatic control and moni-
toring systems. In the near future, very high speed communications will be required to perform protection signaling with a
performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3
milliseconds. This has been established by the IEC 61850 standard.
IEDs with the capabilities outlined above will also provide significantly more power system data than is presently available,
enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control sys-
tems. This new generation of equipment must also be easily incorporated into automation systems, at both the station and
enterprise levels. The GE Multilin Universal Relay (UR) has been developed to meet these goals.

 1 GETTING STARTED 1.2 UR OVERVIEW

1.2.2 HARDWARE ARCHITECTURE

a) UR BASIC DESIGN 1
The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output
signals. The UR can communicate over a local area network (LAN) with an operator interface, a programming device, or
another UR device.

Figure 1–2: UR CONCEPT BLOCK DIAGRAM

The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as program-
mable logic gates, timers, and latches for control features.
Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into
logic signals used by the relay.
Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used
to control field devices.

b) UR SIGNAL TYPES
The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’
contacts are supported.
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic™ equations.
The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec-
tors (RTDs).
The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines.
The UR-series relays support 1 A and 5 A CTs.
The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series
devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic™
operands inserted into IEC 61850 GSSE and GOOSE messages.
The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a
dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are con-
nected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilot-
aided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.

1 The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the
logic program (FlexLogic™ equation), and then sets each output to the appropriate state in an output status table. Any
resulting task execution is priority interrupt-driven.

1.2.3 SOFTWARE ARCHITECTURE

The firmware (software embedded in the relay) is designed in functional modules which can be installed in any relay as
required. This is achieved with Object-Oriented Design and Programming (OOD/OOP) techniques.
Object-Oriented techniques involve the use of ‘objects’ and ‘classes’. An ‘object’ is defined as “a logical entity that contains
both data and code that manipulates that data”. A ‘class’ is the generalized form of similar objects. By using this concept,
one can create a Protection Class with the Protection Elements as objects of the class such as Time Overcurrent, Instanta-
neous Overcurrent, Current Differential, Undervoltage, Overvoltage, Underfrequency, and Distance. These objects repre-
sent completely self-contained software modules. The same object-class concept can be used for Metering, Input/Output
Control, HMI, Communications, or any functional entity in the system.
Employing OOD/OOP in the software architecture of the Universal Relay achieves the same features as the hardware
architecture: modularity, scalability, and flexibility. The application software for any Universal Relay (e.g. Feeder Protection,
Transformer Protection, Distance Protection) is constructed by combining objects from the various functionality classes.
This results in a ’common look and feel’ across the entire family of UR-series platform-based applications.

1.2.4 IMPORTANT CONCEPTS

As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understand-
ing of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in
“elements”. A description of the UR-series elements can be found in the Introduction to Elements section in Chapter 5. An
example of a simple element, and some of the organization of this manual, can be found in the Digital Elements section. An
explanation of the use of inputs from CTs and VTs is in the Introduction to AC Sources section in Chapter 5. A description of
how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic™ section in Chapter 5.

carefully.

1.4.2 COMMUNICATIONS

The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ether-
net ports. To communicate via the faceplate RS232 port, a standard “straight-through” serial cable is used. The DB-9 male
end is connected to the relay and the DB-9 or DB-25 female end is connected to the PC COM1 or COM2 port as described
in the CPU Communications Ports section of Chapter 3.

Figure 1–4: RELAY COMMUNICATIONS OPTIONS

To communicate through the F35 rear RS485 port from a PC RS232 port, the GE Multilin RS232/RS485 converter box is
required. This device (catalog number F485) connects to the computer using a “straight-through” serial cable. A shielded
twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the F35 rear communications port. The converter termi-
nals (+, –, GND) are connected to the F35 communication module (+, –, COM) terminals. Refer to the CPU Communica-
tions Ports section in Chapter 3 for option details. The line should be terminated with an R-C network (i.e. 120 Ω, 1 nF) as
described in the Chapter 3.

1.4.3 FACEPLATE DISPLAY

All messages are displayed on a 2 × 20 character vacuum fluorescent display to make them visible under poor lighting con-
ditions. An optional liquid crystal display (LCD) is also available. Messages are displayed in English and do not require the
aid of an instruction manual for deciphering. While the keypad and display are not actively being used, the display will
default to defined messages. Any high priority event driven message will automatically override the default message and
appear on the display.

1.5.7 COMMISSIONING

Templated tables for charting all the required settings before entering them via the keypad are available from the GE Multi-
1
lin website at http://www.GEindustrial.com/multilin.
The F35 requires a minimum amount of maintenance when it is commissioned into service. The F35 is a microprocessor-
based relay and its characteristics do not change over time. As such no further functional tests are required.
Furthermore the F35 performs a number of ongoing self-tests and takes the necessary action in case of any major errors
(see the Relay Self-Test section in Chapter 7 for details). However, it is recommended that maintenance on the F35 be
scheduled with other system maintenance. This maintenance may involve the following.
In-service maintenance:
1. Visual verification of the analog values integrity such as voltage and current (in comparison to other devices on the cor-
responding system).
2. Visual verification of active alarms, relay display messages, and LED indications.
3. LED test.
4. Visual inspection for any damage, corrosion, dust, or loose wires.
5. Event recorder file download with further events analysis.
Out-of-service maintenance:
1. Check wiring connections for firmness.
2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated
test equipment is required.
3. Protection elements setpoints verification (analog values injection or visual verification of setting file entries against
relay settings schedule).
4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the
system functional testing.
5. Visual inspection for any damage, corrosion, or dust.
6. Event recorder file download with further events analysis.
7. LED Test and pushbutton continuity check.
Unscheduled maintenance such as during a disturbance causing system interruption:
1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements.
If it is concluded that the relay or one of its modules is of concern, contact GE Multilin or one of its representatives for
prompt service.

 2 PRODUCT DESCRIPTION 2.1 INTRODUCTION

2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW

The F35 Multiple Feeder Management Relay is a microprocessor based relay designed for the protection of up to 5 feeders
with busbar voltage measurement or up to 6 feeders without busbar voltage.
Overcurrent and undervoltage protection, breaker recloser, underfrequency, fault diagnostics, and RTU functions are pro-
vided. The F35 provides phase, neutral/ground, instantaneous and time overcurrent protection. The time overcurrent func-
tion provides multiple curve shapes or FlexCurve™ for optimum co-ordination.
Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total
2
waveform RMS magnitude, or as fundamental frequency only RMS magnitude and angle (phasor). Voltage harmonics and
THD metering are also included with the relay.
Diagnostic features include a sequence of records capable of storing 1024 time-tagged events. The internal clock used for
time-tagging can be synchronized with an IRIG-B signal or via the SNTP protocol over the Ethernet port. This precise time
stamping allows the sequence of events to be determined throughout the system. Events can also be programmed (via
FlexLogic™ equations) to trigger oscillography data capture which may be set to record the measured parameters before
and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and sim-
plify report generation in the event of a system fault.
A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual val-
ues. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and
engineering staff. All serial ports use the Modbus® RTU protocol. The RS485 ports may be connected to system computers
with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules
include a 10BaseF Ethernet interface which can be used to provide fast, reliable communications in noisy environments.
Another option provides two 10BaseF fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus®/
TCP, and TFTP protocols, and allows access to the relay via any standard web browser (F35 web pages). The IEC 60870-
5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.
The F35 IEDs use flash memory technology which allows field upgrading as new features are added. The following Single
Line Diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.

3 HARDWARE 3.1DESCRIPTION 3.1.1 PANEL CUTOUT

The relay is available as a 19-inch rack horizontal mount unit or as a reduced size (¾) vertical mount unit, with a removable
faceplate. The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The face-
plate is hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with lim-
ited rear depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting
to access the keypad or RS232 communications port.
The vertical and horizontal case dimensions are shown below, along with panel cutout details for panel mounting. When
planning the location of your panel cutout, ensure that provision is made for the faceplate to swing open without interfer-
ence to or from adjacent equipment.
The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator
access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws
supplied with the relay.

3.1.2 MODULE WITHDRAWAL AND INSERTION

Module withdrawal and insertion may only be performed when control power has been removed from the
unit. Inserting an incorrect module type into a slot may result in personal injury, damage to the unit or con-
WARNING
nected equipment, or undesired operation!
Proper electrostatic discharge protection (i.e. a static strap) must be used when coming in contact with
modules while the relay is energized!
WARNING

The relay, being modular in design, allows for the withdrawal and insertion of modules. Modules must only be replaced with
like modules in their original factory configured slots. The faceplate can be opened to the left, once the sliding latch on the
right side has been pushed up, as shown below. This allows for easy accessibility of the modules for withdrawal.

Figure 3–5: UR MODULE WITHDRAWAL/INSERTION

• MODULE WITHDRAWAL: The ejector/inserter clips, located at the top and bottom of each module, must be pulled
simultaneously to release the module for removal. Before performing this action, control power must be removed
from the relay. Record the original location of the module to ensure that the same or replacement module is inserted
into the correct slot. Modules with current input provide automatic shorting of external CT circuits.
• MODULE INSERTION: Ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simulta-
neously. When the clips have locked into position, the module will be fully inserted.
All CPU modules except the 9E are equipped with 10Base-T or 10Base-F Ethernet connectors. These connectors
must be individually disconnected from the module before it can be removed from the chassis.
NOTE

The version 4.0 release of the F35 relay includes new hardware (CPU and CT/VT modules). The new CPU mod-
ules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R. The new CT/VT modules
NOTE
are specified with the following order codes: 8F, 8G, 8H, 8J.
The new CT/VT modules (8F, 8G, 8H, 8J) can only be used with new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P,
9R); similarly, old CT/VT modules (8A, 8B, 8C, 8D) can only be used with old CPUs (9A, 9C, 9D). To prevent hard-
ware mismatches, the new modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and DSP
module label colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module,
the relay will not function and a DSP ERROR or HARDWARE MISMATCH error will be displayed.
All other input/output modules are compatible with the new hardware. Firmware versions 4.0x and higher are only
compatible with the new CPU and CT/VT modules. Previous versions of the firmware (3.4x and earlier) are only
compatible with the older CPU and CT/VT modules.

Do not touch any rear terminals while the relay is energized!
WARNING

The relay follows a convention with respect to terminal number assignments which are three characters long assigned in
order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the
first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following
figure for an example of rear terminal assignments.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused by high peak voltage
transients, radio frequency interference (RFI), and electromagnetic interference (EMI). These protective components can
be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one
minute.

3.2.3 CONTROL POWER

CONTROL POWER SUPPLIED TO THE RELAY MUST BE CONNECTED TO THE MATCHING POWER SUPPLY
RANGE OF THE RELAY. IF THE VOLTAGE IS APPLIED TO THE WRONG TERMINALS, DAMAGE MAY
CAUTION
OCCUR!
The F35 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well
known to be subject to deterioration over time if voltage is not applied periodically. Deterioration can be
NOTE
avoided by powering the relays up once a year.
The power supply module can be ordered for two possible voltage ranges, with or without a redundant power option. Each
range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical Specifica-
tions section of Chapter 2 for additional details):
LO range: 24 to 48 V (DC only) nominal
HI range: 125 to 250 V nominal
The power supply module provides power to the relay and supplies power for dry contact input connections.
The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the
Typical Wiring Diagram earlier). The critical failure relay is a Form-C that will be energized once control power is applied
and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a
critical failure (see the Self-Test Errors table in Chapter 7) or control power is lost, the relay will de-energize.
For high reliability systems, the F35 has a redundant option in which two F35 power supplies are placed in parallel on the
bus. If one of the power supplies become faulted, the second power supply will assume the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay
of the module will also indicate a faulted power supply.
An LED on the front of the module shows the status of the power supply:

3.2.4 CT/VT MODULES

A CT/VT module may have voltage inputs on Channels 1 through 4 inclusive, or Channels 5 through 8 inclusive. Channels
1 and 5 are intended for connection to Phase A, and are labeled as such in the relay. Channels 2 and 6 are intended for
connection to Phase B, and are labeled as such in the relay. Channels 3 and 7 are intended for connection to Phase C and
are labeled as such in the relay. Channels 4 and 8 are intended for connection to a single phase source. If voltage, this
channel is labelled the auxiliary voltage (VX). If current, this channel is intended for connection to a CT between a system
neutral and ground, and is labelled the ground current (IG).

a) CT INPUTS
VERIFY THAT THE CONNECTION MADE TO THE RELAY NOMINAL CURRENT OF 1 A OR 5 A MATCHES
THE SECONDARY RATING OF THE CONNECTED CTs. UNMATCHED CTs MAY RESULT IN EQUIPMENT
CAUTION
DAMAGE OR INADEQUATE PROTECTION.
The CT/VT module may be ordered with a standard ground current input that is the same as the phase current inputs (Type
8F) or with a sensitive ground input (Type 8G) which is 10 times more sensitive (see the Technical Specifications section for
additional details). Each AC current input has an isolating transformer and an automatic shorting mechanism that shorts the
input when the module is withdrawn from the chassis. There are no internal ground connections on the current inputs. Cur-
rent transformers with 1 to 50000 A primaries and 1 A or 5 A secondaries may be used.
CT connections for both ABC and ACB phase rotations are identical as shown in the Typical Wiring Diagram.
The exact placement of a zero-sequence CT so that ground fault current will be detected is shown below. Twisted pair
cabling on the zero-sequence CT is recommended.

3.2.5 CONTACT INPUTS/OUTPUTS

Every digital input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight
rows in total. A given row of three terminals may be used for the outputs of one relay. For example, for Form-C relay out-
puts, the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a
Form-A output, there are options of using current or voltage detection for feature supervision, depending on the module
ordered. The terminal configuration for contact inputs is different for the two applications.
The digital inputs are grouped with a common return. The F35 has two versions of grouping: four inputs per common return
and two inputs per common return. When a digital input/output module is ordered, four inputs per common is used. The four
inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs sharing one
common. If the inputs must be isolated per row, then two inputs per common return should be selected (4D module).
The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that may
3 be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot
position and row number. However, since there are two contact inputs per row, these names are assigned by module slot
position, row number, and column position.
UR-SERIES FORM-A / SOLID STATE (SSR) OUTPUT CONTACTS:
Some Form-A/SSR outputs include circuits to monitor the DC voltage across the output contact when it is open, and the DC
current through the output contact when it is closed. Each of the monitors contains a level detector whose output is set to
logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On = 1” when the
current is above about 1 to 2.5 mA, and the current monitor is set to “On = 1” when the current exceeds about 80 to 100
mA. The voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to
seal-in the output contact until an external contact has interrupted current flow. The block diagrams of the circuits are below
above for the Form-A outputs with:
a) optional voltage monitor

The operation of voltage and current monitors is reflected with the corresponding FlexLogic™ operands (Cont Op # Von, Cont
Op # Voff, Cont Op # Ion, and Cont Op # Ioff) which can be used in protection, control and alarm logic. The typical application of
the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the
control command. Refer to the Digital Elements section of Chapter 5 for an example of how Form-A/SSR contacts can be
applied for breaker trip circuit integrity monitoring.
Relay contacts must be considered unsafe to touch when the unit is energized! If the relay contacts need to
be used for low voltage accessible applications, it is the customer’s responsibility to ensure proper insula-
WARNING
tion levels!
USE OF FORM-A/SSR OUTPUTS IN HIGH IMPEDANCE CIRCUITS

NOTE For Form-A/SSR output contacts internally equipped with a voltage measuring cIrcuit across the contact, the circuit
has an impedance that can cause a problem when used in conjunction with external high input impedance monitor-
ing equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the
Form-A contact as being closed after it has closed and subsequently opened, when measured as an impedance.
3
The solution to this problem is to use the voltage measuring trigger input of the relay test set, and connect the
Form-A contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power sup-
ply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the
Form-A contact or the resistor can be used to monitor the state of the output.
Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number
sign "#" appears, substitute the contact number
NOTE

When current monitoring is used to seal-in the Form-A/SSR contact outputs, the FlexLogic™ operand driv-
ing the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in
NOTE
situations when the element initiating the contact output is bouncing, at values in the region of the pickup
value).

CONTACT INPUTS:
A dry contact has one side connected to Terminal B3b. This is the positive 48 V DC voltage rail supplied by the power sup-
ply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group
has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply
module. When a dry contact closes, a current of 1 to 3 mA will flow through the associated circuit.
A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact
is connected to the required contact input terminal. In addition, the negative side of the external source must be connected
to the relay common (negative) terminal of each contact input group. The maximum external source voltage for this
arrangement is 300 V DC.
The voltage threshold at which each group of four contact inputs will detect a closed contact input is programmable as
17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

NOTE

CONTACT OUTPUTS:
Contact outputs may be ordered as Form-A or Form-C. The Form A contacts may be connected for external circuit supervi-
sion. These contacts are provided with voltage and current monitoring circuits used to detect the loss of DC voltage in the
circuit, and the presence of DC current flowing through the contacts when the Form-A contact closes. If enabled, the cur-
rent monitoring can be used as a seal-in signal to ensure that the Form-A contact does not attempt to break the energized
inductive coil circuit and weld the output contacts.
There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We
recommend using an external DC supply.

USE OF CONTACT INPUTS WITH AUTO-BURNISHING:

The contact inputs sense a change of the state of the external device contact based on the measured current. When exter-
nal devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to vari-
ous types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface
of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to
establish circuit continuity – an impulse of higher than normal current can accomplish this.
The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation
layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The
impulse will have a 5 second delay after a contact input changes state.

Figure 3–16: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with auto-
burnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to
50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the con-
tacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts
when external device contact bouncing is over.
Another important difference between the auto-burnishing input module and the regular input modules is that only two con-
tact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Digital Input/
Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Conse-
quently, the threshold voltage setting is also defined per group of two contact inputs.
The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP
switch for each contact, for a total of 16 inputs.

3.2.6 TRANSDUCER INPUTS/OUTPUTS

Transducer input modules can receive input signals from external dcmA output transducers (dcmA In) or resistance tem-
perature detectors (RTD). Hardware and software is provided to receive signals from these external transducers and con-
vert these signals into a digital format for use as required.
Transducer output modules provide DC current outputs in several standard dcmA ranges. Software is provided to configure
virtually any analog quantity used in the relay to drive the analog outputs.
Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three ter-
minals per row with a total of eight rows. A given row may be used for either inputs or outputs, with terminals in column "a"
having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/
output channel, the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to Terminal 8b. The current outputs
require a twisted-pair shielded cable, where the shield is grounded at one end only. The figure below illustrates the trans- 3
ducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that may be ordered for the relay.
Wherever a tilde “~” symbol appears, substitute with the Slot Position of the module.

Figure 3–20: CPU MODULE COMMUNICATIONS WIRING

b) RS485 PORTS
RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternat-
ing over the same two wires. Through the use of these port(s), continuous monitoring and control from a remote computer,
SCADA system or PLC is possible.
To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be
observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–”
terminals connected together. The COM terminal should be connected to the common wire inside the shield, when pro-
vided. To avoid loop currents, the shield should be grounded at one point only. Each relay should also be daisy chained to
the next one in the link. A maximum of 32 relays can be connected in this manner without exceeding driver capability. For
larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters to
increase the number of relays on a single channel to more than 32. Star or stub connections should be avoided entirely.
Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the
communication link. For this reason, surge protection devices are internally provided at both communication ports. An iso-
lated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all
equipment should have similar transient protection devices installed.
Both ends of the RS485 circuit should also be terminated with an impedance as shown below.

CAUTION
OBSERVING ANY FIBER TRANSMITTER OUTPUT MAY CAUSE INJURY TO THE EYE.

CAUTION

The fiber optic communication ports allow for fast and efficient communications between relays at 10 or 100Mbps. Optical
fiber may be connected to the relay supporting a wavelength of 820 nm in multi-mode or 1310 nm in multi-mode and single-
mode. The 10 Mbps rate is available for CPU modules 9G and 9H; 100Mbps is available for modules 9J, 9K, 9L, and 9M.
The 9H, 9K and 9M modules have a second pair of identical optical fiber transmitter and receiver for redundancy.
The optical fiber sizes supported include 50/125 µm, 62.5/125 µm and 100/140 µm for 10 Mbps. The fiber optic port is
designed such that the response times will not vary for any core that is 100 µm or less in diameter, 62.5 µm for 100 Mbps.
For optical power budgeting, splices are required every 1 km for the transmitter/receiver pair. When splicing optical fibers,
the diameter and numerical aperture of each fiber must be the same. In order to engage or disengage the ST type connec-
tor, only a quarter turn of the coupling is required.

3.3DIRECT INPUT/OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION

The F35 direct inputs/outputs feature makes use of the Type 7 series of communications modules. These modules are also
used by the L90 Line Differential Relay for inter-relay communications. The direct input/output feature uses the communica-
tions channel(s) provided by these modules to exchange digital state information between relays. This feature is available
on all UR-series relay models except for the L90 Line Differential relay.
The communications channels are normally connected in a ring configuration as shown below. The transmitter of one mod-
ule is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver
of the next module in the ring. This is continued to form a communications ring. The figure below illustrates a ring of four
UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx, and UR4-Tx
to UR1-Rx. A maximum of sixteen (16) UR-series relays can be connected in a single ring

The following diagram shows the connection for three UR-series relays using two independent communication channels.
UR1 and UR3 have single Type 7 communication modules; UR2 has a dual-channel module. The two communication
channels can be of different types, depending on the Type 7 modules used. To allow the direct input/output data to ‘cross-
over’ from Channel 1 to Channel 2 on UR2, the DIRECT I/O CHANNEL CROSSOVER setting should be “Enabled” on UR2. This
forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

and “B” is equivalent to “–”.

b) G.703 SELECTION SWITCH PROCEDURES

1. Remove the G.703 module (7R or 7S):
The ejector/inserter clips located at the top and at the bottom of each module, must be pulled simultaneously in order
to release the module for removal. Before performing this action, control power must be removed from the relay.
The original location of the module should be recorded to help ensure that the same or replacement module is inserted
into the correct slot.
2. Remove the module cover screw.
3. Remove the top cover by sliding it towards the rear and then lift it upwards.
4. Set the Timing Selection Switches (Channel 1, Channel 2) to the desired timing modes.
5. Replace the top cover and the cover screw.

 3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

6. Re-insert the G.703 module Take care to ensure that the correct module type is inserted into the correct slot position.
The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as
the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the
clips simultaneously. When the clips have locked into position, the module will be fully inserted.

Table 3–4: G.703 TIMING SELECTIONS

SWITCHES FUNCTION
S1 OFF → Octet Timing Disabled
ON → Octet Timing 8 kHz
S5 and S6 S5 = OFF and S6 = OFF → Loop Timing Mode
S5 = ON and S6 = OFF → Internal Timing Mode
S5 = OFF and S6 = ON → Minimum Remote Loopback Mode
S5 = ON and S6 = ON → Dual Loopback Mode

c) OCTET TIMING (SWITCH S1)

If Octet Timing is enabled (ON), this 8 kHz signal will be asserted during the violation of Bit 8 (LSB) necessary for connect-
ing to higher order systems. When F35s are connected back to back, Octet Timing should be disabled (OFF).

d) TIMING MODES (SWITCHES S5 AND S6)

There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default).
• Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in
the Internal Timing Mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set for Octet Timing
(S1 = OFF) and Timing Mode = Internal Timing (S5 = ON and S6 = OFF).
• Loop Timing Mode: The system clock is derived from the received line signal. Therefore, the G.703 timing selection
should be in Loop Timing Mode for connections to higher order systems. For connection to a higher order system (UR-
to-multiplexer, factory defaults), set to Octet Timing (S1 = ON) and set Timing Mode = Loop Timing (S5 = OFF and S6
= OFF).

e) TEST MODES (SWITCHES S5 AND S6)

MINIMUM REMOTE LOOPBACK MODE: 3
In Minimum Remote Loopback mode, the multiplexer is enabled to return the data from the external interface without any
processing to assist in diagnosing G.703 Line Side problems irrespective of clock rate. Data enters from the G.703 inputs,
passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer
and then returns to the transmitter. The Differential Received Data is processed and passed to the G.703 Transmitter mod-
ule after which point the data is discarded. The G.703 Receiver module is fully functional and continues to process data and
passes it to the Differential Manchester Transmitter module. Since timing is returned as it is received, the timing source is
expected to be from the G.703 line side of the interface.

DMR = Differential Manchester Receiver

DMR G7X DMX = Differential Manchester Transmitter
G7X = G.703 Transmitter
G7R = G.703 Receiver

DMX G7R

DUAL LOOPBACK MODE:

In Dual Loopback Mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/
transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data
enters the Differential Manchester Receiver module and then is returned to the Differential Manchester Transmitter module.
Likewise, G.703 data enters the G.703 Receiver module and is passed through to the G.703 Transmitter module to be
returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks
are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing. One
source lies on the G.703 line side of the interface while the other lies on the Differential Manchester side of the interface.

3.3.5 RS422 INTERFACE

a) DESCRIPTION
The following figure shows the RS422 2-terminal interface configuration at 64 kbps. AWG 24 twisted shielded pair is recom-
mended for external connections. This interface module is protected by surge suppression devices which optically isolated.
SHIELD TERMINATION
The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:
Site 1: Terminate shield to pins 6a and/or 7b; Site 2: Terminate shield to ‘COM’ pin 2b.
The clock terminating impedance should match the impedance of the line.

The following figure shows the typical pin interconnection between two RS422 interfaces. All pin interconnections are to be
maintained for a connection to a multiplexer.

Figure 3–33: TYPICAL PIN INTERCONNECTION BETWEEN TWO RS422 INTERFACES

b) TWO CHANNEL APPLICATIONS VIA MULTIPLEXERS

The RS422 Interface may be used for single or two channel applications over SONET/SDH and/or multiplexed systems.
When used in single channel applications, the RS422 interface links to higher order systems in a typical fashion observing
transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two channel applications, certain cri-
teria must be followed since there is one clock input for the two RS422 channels. The system will function correctly if the
following connections are observed and your data module has a terminal timing feature. Terminal timing is a common fea-
ture to most synchronous data units that allows the module to accept timing from an external source. Using the terminal
timing feature, two channel applications can be achieved if these connections are followed: The send timing outputs from
the multiplexer (data module 1), will connect to the Clock inputs of the UR–RS422 interface in the usual fashion. In addition,
the send timing outputs of data module 1 will also be paralleled to the terminal timing inputs of data module 2. By using this
configuration, the timing for both data modules and both UR–RS422 channels will be derived from a single clock source. As
a result, data sampling for both of the UR–RS422 channels will be synchronized via the send timing leads on data module
1 as shown below. If the terminal timing feature is not available or this type of connection is not desired, the G.703 interface
is a viable option that does not impose timing restrictions.

Figure 3–34: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the F35 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides
timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been
omitted in the figure above since they may vary depending on the manufacturer.

c) TRANSIT TIMING
The RS422 Interface accepts one clock input for Transmit Timing. It is important that the rising edge of the 64 kHz Transmit
Timing clock of the Multiplexer Interface is sampling the data in the center of the Transmit Data window. Therefore, it is
important to confirm Clock and Data Transitions to ensure Proper System Operation. For example, the following figure
shows the positive edge of the Tx Clock in the center of the Tx Data bit.

 3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

d) RECEIVE TIMING
The RS422 Interface utilizes NRZI-MARK Modulation Code and; therefore, does not rely on an Rx Clock to recapture data.
NRZI-MARK is an edge-type, invertible, self-clocking code.
To recover the Rx Clock from the data-stream, an integrated DPLL (Digital Phase Lock Loop) circuit is utilized. The DPLL is
driven by an internal clock, which is over-sampled 16X, and uses this clock along with the data-stream to generate a data
clock that can be used as the SCC (Serial Communication Controller) receive clock.

3.3.6 RS422 AND FIBER INTERFACE

The following figure shows the combined RS422 plus Fiber interface configuration at 64K baud. The 7L, 7M, 7N, 7P, and 74
modules are used in 2-terminal with a redundant channel or 3-terminal configurations where Channel 1 is employed via the
RS422 interface (possibly with a multiplexer) and Channel 2 via direct fiber.
3 AWG 24 twisted shielded pair is recommended for external RS422 connections and the shield should be grounded only at
one end. For the direct fiber channel, power budget issues should be addressed properly.
When using a LASER Interface, attenuators may be necessary to ensure that you do not exceed Maximum
Optical Input Power to the receiver.

3.3.8 IEEE C37.94 INTERFACE

The UR-series IEEE C37.94 communication modules (76 and 77) are designed to interface with IEEE C37.94 compliant
digital multiplexers and/or an IEEE C37.94 compliant interface converter for use with direct input/output applications for
firmware revisions 3.30 and higher. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data
between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to
64n kbps, where n = 1, 2,…, 12. The UR-series C37.94 communication module is 64 kbps only with n fixed at 1. The frame
is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of framing and
data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.
The specifications for the module are as follows:
IEEE standard: C37.94 for 1 × 64 kbps optical fiber interface
Fiber optic cable type: 50 mm or 62.5 mm core diameter optical fiber
Fiber optic mode: multi-mode
Fiber optic cable length: up to 2 km

 4 HUMAN INTERFACES 4.1 ENERVISTA UR SETUP SOFTWARE INTERFACE

4 HUMAN INTERFACES 4.1ENERVISTA UR SETUP SOFTWARE INTERFACE 4.1.1 INTRODUCTION

The EnerVista UR Setup software provides a graphical user interface (GUI) as one of two human interfaces to a UR device.
The alternate human interface is implemented via the device’s faceplate keypad and display (see Faceplate Interface sec-
tion in this chapter).
The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and trouble-shoot the operation
of relay functions, connected over local or wide area communication networks. It can be used while disconnected (i.e. off-
line) or connected (i.e. on-line) to a UR device. In off-line mode, settings files can be created for eventual downloading to
the device. In on-line mode, you can communicate with the device in real-time.
The EnerVista UR Setup software, provided with every F35 relay, can be run from any computer supporting Microsoft Win-
dows® 95, 98, NT, 2000, ME, and XP. This chapter provides a summary of the basic EnerVista UR Setup software interface
features. The EnerVista UR Setup Help File provides details for getting started and using the EnerVista UR Setup software
interface.

4.1.2 CREATING A SITE LIST

To start using the EnerVista UR Setup software, a site definition and device definition must first be created. See the EnerV-
ista UR Setup Help File or refer to the Connecting EnerVista UR Setup with the F35 section in Chapter 1 for details.

4.1.3 ENERVISTA UR SETUP SOFTWARE OVERVIEW

4
a) ENGAGING A DEVICE
The EnerVista UR Setup software may be used in on-line mode (relay connected) to directly communicate with a UR relay.
Communicating relays are organized and grouped by communication interfaces and into sites. Sites may contain any num-
ber of relays selected from the UR product series.

b) USING SETTINGS FILES

The EnerVista UR Setup software interface supports three ways of handling changes to relay settings:
• In off-line mode (relay disconnected) to create or edit relay settings files for later download to communicating relays.
• While connected to a communicating relay to directly modify any relay settings via relay data view windows, and then
save the settings to the relay.
• You can create/edit settings files and then write them to the relay while the interface is connected to the relay.
Settings files are organized on the basis of file names assigned by the user. A settings file contains data pertaining to the
following types of relay settings:
• Device Definition
• Product Setup
• System Setup
• FlexLogic™
• Grouped Elements
• Control Elements
• Inputs/Outputs
• Testing
Factory default values are supplied and can be restored after any changes.

c) CREATING AND EDITING FLEXLOGIC™

You can create or edit a FlexLogic™ equation in order to customize the relay. You can subsequently view the automatically
generated logic diagram.

GE Multilin F35 Multiple Feeder Management Relay 4-1

 4.1 ENERVISTA UR SETUP SOFTWARE INTERFACE 4 HUMAN INTERFACES

d) VIEWING ACTUAL VALUES

You can view real-time relay data such as input/output status and measured parameters.

e) VIEWING TRIGGERED EVENTS

While the interface is in either on-line or off-line mode, you can view and analyze data generated by triggered specified
parameters, via one of the following:
• Event Recorder facility: The event recorder captures contextual data associated with the last 1024 events, listed in
chronological order from most recent to oldest.
• Oscillography facility: The oscillography waveform traces and digital states are used to provide a visual display of
power system and relay operation data captured during specific triggered events.

f) FILE SUPPORT
• Execution: Any EnerVista UR Setup file which is double clicked or opened will launch the application, or provide focus
to the already opened application. If the file was a settings file (has a URS extension) which had been removed from
the Settings List tree menu, it will be added back to the Settings List tree menu.
• Drag and Drop: The Site List and Settings List control bar windows are each mutually a drag source and a drop target
for device-order-code-compatible files or individual menu items. Also, the Settings List control bar window and any
4 Windows Explorer directory folder are each mutually a file drag source and drop target.
New files which are dropped into the Settings List window are added to the tree which is automatically sorted alphabet-
ically with respect to settings file names. Files or individual menu items which are dropped in the selected device menu
in the Site List window will automatically be sent to the on-line communicating device.

g) FIRMWARE UPGRADES
The firmware of a F35 device can be upgraded, locally or remotely, via the EnerVista UR Setup software. The correspond-
ing instructions are provided by the EnerVista UR Setup Help file under the topic “Upgrading Firmware”.
Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (i.e. default
values, minimum/maximum values, data type, and item size) may change slightly from version to version of firm-
NOTE
ware. The addresses are rearranged when new features are added or existing features are enhanced or modified.
The EEPROM DATA ERROR message displayed after upgrading/downgrading the firmware is a resettable, self-test
message intended to inform users that the Modbus addresses have changed with the upgraded firmware. This
message does not signal any problems when appearing after firmware upgrades.

4.2.3 DISPLAY

All messages are displayed on a 2 × 20 character vacuum fluorescent display to make them visible under poor lighting con-
ditions. An optional liquid crystal display (LCD) is also available. Messages are displayed in English and do not require the
aid of an instruction manual for deciphering. While the keypad and display are not actively being used, the display will
default to defined messages. Any high priority event driven message will automatically override the default message and
appear on the display.

4.2.4 KEYPAD

Display messages are organized into ‘pages’ under the following headings: Actual Values, Settings, Commands, and Tar-
gets. The key navigates through these pages. Each heading page is broken down further into logical subgroups.
The MESSAGE keys navigate through the subgroups. The VALUE keys scroll increment or decrement
numerical setting values when in programming mode. These keys also scroll through alphanumeric values in the text edit
mode. Alternatively, values may also be entered with the numeric keypad.

4.2.6 CHANGING SETTINGS

a) ENTERING NUMERICAL DATA

Each numerical setting has its own minimum, maximum, and increment value associated with it. These parameters define
what values are acceptable for a setting.

FLASH MESSAGE For example, select the SETTINGS PRODUCT SETUP DISPLAY PROPERTIES FLASH
TIME: 1.0 s MESSAGE TIME setting.

MINIMUM: 0.5 Press the key to view the minimum and maximum values. Press the key
MAXIMUM: 10.0 again to view the next context sensitive help message.

Two methods of editing and storing a numerical setting value are available.
• 0 to 9 and (decimal point): The relay numeric keypad works the same as that of any electronic calculator. A num-
ber is entered one digit at a time. The leftmost digit is entered first and the rightmost digit is entered last. Pressing the
MESSAGE key or pressing the ESCAPE key, returns the original value to the display.
• VALUE : The VALUE key increments the displayed value by the step value, up to the maximum value
4 allowed. While at the maximum value, pressing the VALUE
upward from the minimum value. The VALUE
key again will allow the setting selection to continue
key decrements the displayed value by the step value, down to the
minimum value. While at the minimum value, pressing the VALUE key again will allow the setting selection to con-
tinue downward from the maximum value.

FLASH MESSAGE As an example, set the flash message time setting to 2.5 seconds. Press the appropriate
TIME: 2.5 s numeric keys in the sequence “2 . 5". The display message will change as the digits are
being entered.
NEW SETTING Until is pressed, editing changes are not registered by the relay. Therefore, press
HAS BEEN STORED to store the new value in memory. This flash message will momentarily appear as
confirmation of the storing process. Numerical values which contain decimal places will
be rounded-off if more decimal place digits are entered than specified by the step value.

b) ENTERING ENUMERATION DATA

Enumeration settings have data values which are part of a set, whose members are explicitly defined by a name. A set is
comprised of two or more members.

ACCESS LEVEL: For example, the selections available for ACCESS LEVEL are "Restricted", "Command",
Restricted "Setting", and "Factory Service".

Enumeration type values are changed using the VALUE keys. The VALUE key displays the next selection while the
VALUE key displays the previous selection.

ACCESS LEVEL: If the ACCESS LEVEL needs to be "Setting", press the VALUE keys until the proper selec-
Setting tion is displayed. Press at any time for the context sensitive help messages.

NEW SETTING Changes are not registered by the relay until the key is pressed. Pressing
HAS BEEN STORED stores the new value in memory. This flash message momentarily appears as confirma-
tion of the storing process.

c) ENTERING ALPHANUMERIC TEXT

Text settings have data values which are fixed in length, but user-defined in character. They may be comprised of upper
case letters, lower case letters, numerals, and a selection of special characters.

5.1.2 INTRODUCTION TO ELEMENTS

In the design of UR relays, the term “element” is used to describe a feature that is based around a comparator. The com-
parator is provided with an input (or set of inputs) that is tested against a programmed setting (or group of settings) to deter-
mine if the input is within the defined range that will set the output to logic 1, also referred to as “setting the flag”. A single
comparator may make multiple tests and provide multiple outputs; for example, the time overcurrent comparator sets a
Pickup flag when the current input is above the setting and sets an Operate flag when the input current has been at a level
above the pickup setting for the time specified by the time-current curve settings. All comparators, except the Digital Ele-
ment which uses a logic state as the input, use analog parameter actual values as the input.
Elements are arranged into two classes, GROUPED and CONTROL. Each element classed as a GROUPED element is
provided with six alternate sets of settings, in setting groups numbered 1 through 6. The performance of a GROUPED ele-
ment is defined by the setting group that is active at a given time. The performance of a CONTROL element is independent
of the selected active setting group.
The main characteristics of an element are shown on the element logic diagram. This includes the input(s), settings, fixed
logic, and the output operands generated (abbreviations used on scheme logic diagrams are defined in Appendix F).
Some settings for current and voltage elements are specified in per-unit (pu) calculated quantities:
pu quantity = (actual quantity) / (base quantity)
• For current elements, the ‘base quantity’ is the nominal secondary or primary current of the CT. Where the current
source is the sum of two CTs with different ratios, the ‘base quantity’ will be the common secondary or primary current
to which the sum is scaled (i.e. normalized to the larger of the 2 rated CT inputs). For example, if CT1 = 300 / 5 A and
CT2 = 100 / 5 A, then in order to sum these, CT2 is scaled to the CT1 ratio. In this case, the ‘base quantity’ will be 5 A
secondary or 300 A primary.

5 • For voltage elements the ‘base quantity’ is the nominal primary voltage of the protected system which corresponds
(based on VT ratio and connection) to secondary VT voltage applied to the relay. For example, on a system with a
13.8 kV nominal primary voltage and with 14400:120 V Delta-connected VTs, the secondary nominal voltage (1 pu)
would be:
13800
---------------- × 120 = 115 V (EQ 5.1)
14400
For Wye-connected VTs, the secondary nominal voltage (1 pu) would be:
13800
---------------- × 120
---------- = 66.4 V (EQ 5.2)
14400 3
Many settings are common to most elements and are discussed below:
• FUNCTION setting: This setting programs the element to be operational when selected as “Enabled”. The factory
default is “Disabled”. Once programmed to “Enabled”, any element associated with the Function becomes active and
all options become available.
• NAME setting: This setting is used to uniquely identify the element.
• SOURCE setting: This setting is used to select the parameter or set of parameters to be monitored.
• PICKUP setting: For simple elements, this setting is used to program the level of the measured parameter above or
below which the pickup state is established. In more complex elements, a set of settings may be provided to define the
range of the measured parameters which will cause the element to pickup.
• PICKUP DELAY setting: This setting sets a time-delay-on-pickup, or on-delay, for the duration between the Pickup
and Operate output states.
• RESET DELAY setting: This setting is used to set a time-delay-on-dropout, or off-delay, for the duration between the
Operate output state and the return to logic 0 after the input transits outside the defined pickup range.
• BLOCK setting: The default output operand state of all comparators is a logic 0 or “flag not set”. The comparator
remains in this default state until a logic 1 is asserted at the RUN input, allowing the test to be performed. If the RUN
input changes to logic 0 at any time, the comparator returns to the default state. The RUN input is used to supervise
the comparator. The BLOCK input is used as one of the inputs to RUN control.

5-4 F35 Multiple Feeder Management Relay GE Multilin

 5 SETTINGS 5.1 OVERVIEW

• TARGET setting: This setting is used to define the operation of an element target message. When set to Disabled, no
target message or illumination of a faceplate LED indicator is issued upon operation of the element. When set to Self-
Reset, the target message and LED indication follow the Operate state of the element, and self-resets once the oper-
ate element condition clears. When set to Latched, the target message and LED indication will remain visible after the
element output returns to logic 0 - until a RESET command is received by the relay.
• EVENTS setting: This setting is used to control whether the Pickup, Dropout or Operate states are recorded by the
event recorder. When set to Disabled, element pickup, dropout or operate are not recorded as events. When set to
Enabled, events are created for:
(Element) PKP (pickup)
(Element) DPO (dropout)
(Element) OP (operate)
The DPO event is created when the measure and decide comparator output transits from the pickup state (logic 1) to
the dropout state (logic 0). This could happen when the element is in the operate state if the reset delay time is not ‘0’.

5.1.3 INTRODUCTION TO AC SOURCES

a) BACKGROUND
The F35 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two
three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail-
ure element. The sum of both breaker phase currents and 3I_0 residual currents may be required for the circuit relaying
and metering functions. For a three-winding transformer application, it may be required to calculate watts and vars for each
of three windings, using voltage from different sets of VTs. These requirements can be satisfied with a single UR, equipped
with sufficient CT and VT input channels, by selecting the parameter to measure. A mechanism is provided to specify the
AC parameter (or group of parameters) used as the input to protection/control comparators and some metering elements.
Selection of the parameter(s) to measure is partially performed by the design of a measuring element or protection/control 5
comparator by identifying the type of parameter (fundamental frequency phasor, harmonic phasor, symmetrical component,
total waveform RMS magnitude, phase-phase or phase-ground voltage, etc.) to measure. The user completes the process
by selecting the instrument transformer input channels to use and some of the parameters calculated from these channels.
The input parameters available include the summation of currents from multiple input channels. For the summed currents of
phase, 3I_0, and ground current, current from CTs with different ratios are adjusted to a single ratio before summation.
A mechanism called a “Source” configures the routing of CT and VT input channels to measurement sub-systems.
Sources, in the context of UR series relays, refer to the logical grouping of current and voltage signals such that one source
contains all the signals required to measure the load or fault in a particular power apparatus. A given source may contain all
or some of the following signals: three-phase currents, single-phase ground current, three-phase voltages and an auxiliary
voltage from a single VT for checking for synchronism.
To illustrate the concept of Sources, as applied to current inputs only, consider the breaker-and-a-half scheme below. In this
application, the current flows as shown by the arrows. Some current flows through the upper bus bar to some other location
or power equipment, and some current flows into transformer Winding 1. The current into Winding 1 is the phasor sum (or
difference) of the currents in CT1 and CT2 (whether the sum or difference is used depends on the relative polarity of the CT
connections). The same considerations apply to transformer Winding 2. The protection elements require access to the net
current for transformer protection, but some elements may need access to the individual currents from CT1 and CT2.

Figure 5–1: BREAKER-AND-A-HALF SCHEME

In conventional analog or electronic relays, the sum of the currents is obtained from an appropriate external connection of
all CTs through which any portion of the current for the element being protected could flow. Auxiliary CTs are required to
perform ratio matching if the ratios of the primary CTs to be summed are not identical. In the UR series of relays, provisions
have been included for all the current signals to be brought to the UR device where grouping, ratio correction and summa-
tion are applied internally via configuration settings.
A major advantage of using internal summation is that the individual currents are available to the protection device; for
example, as additional information to calculate a restraint current, or to allow the provision of additional protection features

5 that operate on the individual currents such as breaker failure.

Given the flexibility of this approach, it becomes necessary to add configuration settings to the platform to allow the user to
select which sets of CT inputs will be added to form the net current into the protected device.
The internal grouping of current and voltage signals forms an internal source. This source can be given a specific name
through the settings, and becomes available to protection and metering elements in the UR platform. Individual names can
be given to each source to help identify them more clearly for later use. For example, in the scheme shown in the above
diagram, the configures one Source to be the sum of CT1 and CT2 and can name this Source as “Wdg 1 Current”.
Once the sources have been configured, the user has them available as selections for the choice of input signal for the pro-
tection elements and as metered quantities.

b) CT/VT MODULE CONFIGURATION

CT and VT input channels are contained in CT/VT modules. The type of input channel can be phase/neutral/other voltage,
phase/ground current, or sensitive ground current. The CT/VT modules calculate total waveform RMS levels, fundamental
frequency phasors, symmetrical components and harmonics for voltage or current, as allowed by the hardware in each
channel. These modules may calculate other parameters as directed by the CPU module.
A CT/VT module contains up to eight input channels, numbered 1 through 8. The channel numbering corresponds to the
module terminal numbering 1 through 8 and is arranged as follows: Channels 1, 2, 3 and 4 are always provided as a group,
hereafter called a “bank,” and all four are either current or voltage, as are Channels 5, 6, 7 and 8. Channels 1, 2, 3 and 5, 6,
7 are arranged as phase A, B and C respectively. Channels 4 and 8 are either another current or voltage.
Banks are ordered sequentially from the block of lower-numbered channels to the block of higher-numbered channels, and
from the CT/VT module with the lowest slot position letter to the module with the highest slot position letter, as follows:
INCREASING SLOT POSITION LETTER -->
CT/VT MODULE 1 CT/VT MODULE 2 CT/VT MODULE 3
< bank 1 > < bank 3 > < bank 5 >
< bank 2 > < bank 4 > < bank 6 >

5-6 F35 Multiple Feeder Management Relay GE Multilin

 5 SETTINGS 5.1 OVERVIEW

The UR platform allows for a maximum of three sets of three-phase voltages and six sets of three-phase currents. The
result of these restrictions leads to the maximum number of CT/VT modules in a chassis to three. The maximum number of
sources is six. A summary of CT/VT module configurations is shown below.
ITEM MAXIMUM NUMBER
CT/VT Module 3
CT Bank (3 phase channels, 1 ground channel) 12
VT Bank (3 phase channels, 1 auxiliary channel) 6

c) CT/VT INPUT CHANNEL CONFIGURATION

Upon relay startup, configuration settings for every bank of current or voltage input channels in the relay are automatically
generated from the order code. Within each bank, a channel identification label is automatically assigned to each bank of
channels in a given product. The ‘bank’ naming convention is based on the physical location of the channels, required by
the user to know how to connect the relay to external circuits. Bank identification consists of the letter designation of the slot
in which the CT/VT module is mounted as the first character, followed by numbers indicating the channel, either 1 or 5.
For three-phase channel sets, the number of the lowest numbered channel identifies the set. For example, F1 represents
the three-phase channel set of F1/F2/F3, where F is the slot letter and 1 is the first channel of the set of three channels.
Upon startup, the CPU configures the settings required to characterize the current and voltage inputs, and will display them
in the appropriate section in the sequence of the banks (as described above) as follows for a maximum configuration: F1,
F5, M1, M5, U1, and U5.
The above section explains how the input channels are identified and configured to the specific application instrument
transformers and the connections of these transformers. The specific parameters to be used by each measuring element
and comparator, and some actual values are controlled by selecting a specific source. The source is a group of current and
voltage input channels selected by the user to facilitate this selection. With this mechanism, a user does not have to make
multiple selections of voltage and current for those elements that need both parameters, such as a distance element or a 5
watt calculation. It also gathers associated parameters for display purposes.
The basic idea of arranging a source is to select a point on the power system where information is of interest. An applica-
tion example of the grouping of parameters in a Source is a transformer winding, on which a three phase voltage is mea-
sured, and the sum of the currents from CTs on each of two breakers is required to measure the winding current flow.

Two levels of password security are provided: Command and Setting. The following command operations are under pass-
word supervision:
changing the state of virtual inputs, clearing the event records, clearing the oscillography records, changing the date
and time, clearing energy records, clearing the data logger, user-programmable pushbuttons
The following setting operations are under password supervision:
changing any setting, test mode operation

5 The Command and Setting passwords are defaulted to "Null" when the relay is shipped from the factory. When a password
is set to "Null", the password security feature is disabled.
Programming a password code is required to enable each access level. A password consists of one to ten numerical char-
acters. When a CHANGE ... PASSWORD setting is set to “Yes”, the following message sequence is invoked:
1. ENTER NEW PASSWORD: ____________
2. VERIFY NEW PASSWORD: ____________
3. NEW PASSWORD HAS BEEN STORED
To gain write access to a "Restricted" setting, set ACCESS LEVEL to "Setting" and then change the setting, or attempt to
change the setting and follow the prompt to enter the programmed password. If the password is correctly entered, access
will be allowed. If no keys are pressed for longer than 30 minutes or control power is cycled, accessibility will automatically
revert to the "Restricted" level.
If an entered password is lost (or forgotten), consult the factory with the corresponding ENCRYPTED PASSWORD.
In the event that an incorrect Command or Setting password has been entered via the faceplate interface three times within
a three-minute time span, the LOCAL ACCESS DENIED FlexLogic™ operand will be set to “On” and the F35 will not allow
Settings or Command access via the faceplate interface for the next ten minutes. The TOO MANY ATTEMPTS – BLOCKED
FOR 10 MIN! flash message will appear upon activation of the ten minute timeout or any other time a user attempts any
change to the defined tier during the ten minute timeout. The LOCAL ACCESS DENIED FlexLogic™ operand will be set to
“Off” after the expiration of the ten-minute timeout.
In the event that an incorrect Command or Setting password has been entered via the any external communications inter-
face three times within a three-minute time span, the REMOTE ACCESS DENIED FlexLogic™ operand will be set to “On” and
the F35 will not allow Settings or Command access via the any external communications interface for the next ten minutes.
The REMOTE ACCESS DENIED FlexLogic™ operand will be set to “Off” after the expiration of the ten-minute timeout.
The F35 provides a means to raise an alarm upon failed password entry. Should password verification fail while accessing
a password-protected level of the relay (either settings or commands), the UNAUTHORIZED ACCESS FlexLogic™ operand is
asserted. The operand can be programmed to raise an alarm via contact outputs or communications. This feature can be
used to protect against both unauthorized and accidental access attempts.

The UNAUTHORIZED ACCESS operand is reset with the COMMANDS CLEAR RECORDS RESET UNAUTHORIZED
ALARMS command. Therefore, to apply this feature with security, the command level should be password-protected. The
operand does not generate events or targets. If these are required, the operand can be assigned to a digital element pro-
grammed with event logs and/or targets enabled.
If the Setting and Command passwords are identical, this one password allows access to both commands
and settings.

Some relay messaging characteristics can be modified to suit different situations using the display properties settings.
• LANGUAGE: This setting selects the language used to display settings, actual values, and targets. The range is
dependent on the order code of the relay.
• FLASH MESSAGE TIME: Flash messages are status, warning, error, or information messages displayed for several
seconds in response to certain key presses during setting programming. These messages override any normal mes-
sages. The duration of a flash message on the display can be changed to accommodate different reading rates.
• DEFAULT MESSAGE TIMEOUT: If the keypad is inactive for a period of time, the relay automatically reverts to a
default message. The inactivity time is modified via this setting to ensure messages remain on the screen long enough
during programming or reading of actual values.
• DEFAULT MESSAGE INTENSITY: To extend phosphor life in the vacuum fluorescent display, the brightness can be
attenuated during default message display. During keypad interrogation, the display always operates at full brightness.
• SCREEN SAVER FEATURE and SCREEN SAVER WAIT TIME: These settings are only visible if the F35 has a liquid
crystal display (LCD) and control its backlighting. When the SCREEN SAVER FEATURE is “Enabled”, the LCD backlighting
is turned off after the DEFAULT MESSAGE TIMEOUT followed by the SCREEN SAVER WAIT TIME, providing that no keys
have been pressed and no target messages are active. When a keypress occurs or a target becomes active, the LCD
backlighting is turned on.
• CURRENT CUT-OFF LEVEL: This setting modifies the current cut-off threshold. Very low currents (1 to 2% of the
rated value) are very susceptible to noise. Some customers prefer very low currents to display as zero, while others
prefer the current be displayed even when the value reflects noise rather than the actual signal. The F35 applies a cut-
off value to the magnitudes and angles of the measured currents. If the magnitude is below the cut-off level, it is substi-

GE Multilin F35 Multiple Feeder Management Relay 5-9

 5.2 PRODUCT SETUP 5 SETTINGS

tuted with zero. This applies to phase and ground current phasors as well as true RMS values and symmetrical compo-
nents. The cut-off operation applies to quantities used for metering, protection, and control, as well as those used by
communications protocols. Note that the cut-off level for the sensitive ground input is 10 times lower that the CURRENT
CUT-OFF LEVEL setting value. Raw current samples available via oscillography are not subject to cut-off.

• VOLTAGE CUT-OFF LEVEL: This setting modifies the voltage cut-off threshold. Very low secondary voltage measure-
ments (at the fractional volt level) can be affected by noise. Some customers prefer these low voltages to be displayed
as zero, while others prefer the voltage to be displayed even when the value reflects noise rather than the actual sig-
nal. The F35 applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below
the cut-off level, it is substituted with zero. This operation applies to phase and auxiliary voltages, and symmetrical
components. The cut-off operation applies to quantities used for metering, protection, and control, as well as those
used by communications protocols. Raw samples of the voltages available via oscillography are not subject cut-off.
The CURRENT CUT-OFF LEVEL and the VOLTAGE CUT-OFF LEVEL are used to determine the metered power cut-off levels. The
power cut-off level is calculated as shown below. For Delta connections:

3 × CURRENT CUT-OFF LEVEL × VOLTAGE CUT-OFF LEVEL × VT primary × CT primary

3-phase power cut-off = -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
- (EQ 5.3)
VT secondary
For Wye connections:
× CURRENT CUT-OFF LEVEL × VOLTAGE CUT-OFF LEVEL × VT primary × CT primary-
3-phase power cut-off = 3
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- (EQ 5.4)
VT secondary
CURRENT CUT-OFF LEVEL × VOLTAGE CUT-OFF LEVEL × VT primary × CT primary
per-phase power cut-off = ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- (EQ 5.5)
VT secondary
where VT primary = VT secondary × VT ratio and CT primary = CT secondary × CT ratio.

5 For example, given the following settings:

CURRENT CUT-OFF LEVEL: “0.02 pu”
VOLTAGE CUT-OFF LEVEL: “1.0 V”
PHASE CT PRIMARY: “100 A”
PHASE VT SECONDARY: “66.4 V”
PHASE VT RATIO: “208.00 : 1"
PHASE VT CONNECTION: “Delta”.

We have:
CT primary = “100 A”, and
VT primary = PHASE VT SECONDARY x PHASE VT RATIO = 66.4 V x 208 = 13811.2 V
The power cut-off is therefore:
power cut-off = (CURRENT CUT-OFF LEVEL × VOLTAGE CUT-OFF LEVEL × CT primary × VT primary)/VT secondary
= ( 3 × 0.02 pu × 1.0 V × 100 A × 13811.2 V) / 66.4 V
= 720.5 watts
Any calculated power value below this cut-off will not be displayed. As well, the three-phase energy data will not accumu-
late if the total power from all three phases does not exceed the power cut-off.
Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower signals
as valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02
NOTE
pu” for CURRENT CUT-OFF LEVEL and “1.0 V” for VOLTAGE CUT-OFF LEVEL are recommended.

Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program-
mable pushbuttons to clear specific records are typical applications for these commands. Since the F35 responds to rising
edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Clearing records with user-programmable operands is not protected by the command password. However, user-program-
mable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-programma-
ble pushbuttons can provide extra security if required.
For example, to assign User-Programmable Pushbutton 1 to clear demand records, the following settings should be
applied.
1. Assign the clear demand function to Pushbutton 1 by making the following change in the SETTINGS PRODUCT SETUP

The F35 is equipped with up to 3 independent serial communication ports. The faceplate RS232 port is intended for local
use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet or
RS485 port. The rear COM2 port is RS485. The RS485 ports have settings for baud rate and parity. It is important that
these parameters agree with the settings used on the computer or other equipment that is connected to these ports. Any of

these ports may be connected to a computer running EnerVista UR Setup. This software can download and upload setting
files, view measured parameters, and upgrade the relay firmware. A maximum of 32 relays can be daisy-chained and con-
nected to a DCS, PLC or PC using the RS485 ports.
For each RS485 port, the minimum time before the port will transmit after receiving data from a host can be

NSAP address is used with the IEC 61850 protocol over the OSI (CLNP/TP4) stack only. Each network protocol has a set- 5
ting for the TCP/UDP PORT NUMBER. These settings are used only in advanced network configurations and should normally
be left at their default values, but may be changed if required (for example, to allow access to multiple UR-series relays
behind a router). By setting a different TCP/UDP PORT NUMBER for a given protocol on each UR-series relay, the router can
map the relays to the same external IP address. The client software (EnerVista UR Setup, for example) must be configured
to use the correct port number if these settings are used.
When the NSAP address, any TCP/UDP Port Number, or any User Map setting (when used with DNP) is changed,
it will not become active until power to the relay has been cycled (OFF/ON).

The serial communication ports utilize the Modbus protocol, unless configured for DNP or IEC 60870-5-104 operation (see
descriptions below). This allows the EnerVista UR Setup software to be used. The UR operates as a Modbus slave device
only. When using Modbus protocol on the RS232 port, the F35 will respond regardless of the MODBUS SLAVE ADDRESS pro-
grammed. For the RS485 ports each F35 must have a unique address from 1 to 254. Address 0 is the broadcast address
which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same
address or conflicts resulting in errors will occur. Generally, each device added to the link should use the next higher
address starting at 1. Refer to Appendix B for more information on the Modbus protocol.
Changes to the MODBUS TCP PORT NUMBER setting will not take effect until the F35 is restarted.

The F35 supports the Distributed Network Protocol (DNP) version 3.0. The F35 can be used as a DNP slave device con-
nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the F35 maintains two sets of DNP
data change buffers and connection information, two DNP masters can actively communicate with the F35 at one time.

The DNP CHANNEL 1(2) PORT settings select the communications port assigned to the DNP protocol for each channel. Once
DNP is assigned to a serial port, the Modbus protocol is disabled on that port. Note that COM1 can be used only in non-
Ethernet UR relays. When this setting is set to “Network - TCP”, the DNP protocol can be used over TCP/IP on channels 1
or 2. When this value is set to “Network - UDP”, the DNP protocol can be used over UDP/IP on channel 1 only. Refer to
Appendix E for additional information on the DNP protocol.
Changes to the DNP CHANNEL 1(2) PORT settings will take effect only after power has been cycled to the relay.

NOTE

The DNP NETWORK CLIENT ADDRESS settings can force the F35 to respond to a maximum of five specific DNP masters. The

The DNP UNSOL RESPONSE FUNCTION should be “Disabled” for RS485 applications since there is no collision avoidance
mechanism. The DNP UNSOL RESPONSE TIMEOUT sets the time the F35 waits for a DNP master to confirm an unsolicited
response. The DNP UNSOL RESPONSE MAX RETRIES setting determines the number of times the F35 retransmits an unsolic-
ited response without receiving confirmation from the master; a value of “255” allows infinite re-tries. The DNP UNSOL
RESPONSE DEST ADDRESS is the DNP address to which all unsolicited responses are sent. The IP address to which unsolic-
ited responses are sent is determined by the F35 from the current TCP connection or the most recent UDP message.
The DNP SCALE FACTOR settings are numbers used to scale Analog Input point values. These settings group the F35 Ana-
log Input data into types: current, voltage, power, energy, and other. Each setting represents the scale factor for all Analog
Input points of that type. For example, if the DNP VOLTAGE SCALE FACTOR setting is set to a value of 1000, all DNP Analog
Input points that are voltages will be returned with values 1000 times smaller (e.g. a value of 72000 V on the F35 will be
5 returned as 72). These settings are useful when analog input values must be adjusted to fit within certain ranges in DNP
masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (i.e. the value will be 10 times larger).
The DNP DEFAULT DEADBAND settings determine when to trigger unsolicited responses containing Analog Input data. These
settings group the F35 Analog Input data into types: current, voltage, power, energy, and other. Each setting represents the
default deadband value for all Analog Input points of that type. For example, to trigger unsolicited responses from the F35
when any current values change by 15 A, the DNP CURRENT DEFAULT DEADBAND setting should be set to “15”. Note that
these settings are the deadband default values. DNP Object 34 points can be used to change deadband values, from the
default, for each individual DNP Analog Input point. Whenever power is removed and re-applied to the F35, the default
deadbands will be in effect.
The DNP TIME SYNC IIN PERIOD setting determines how often the Need Time Internal Indication (IIN) bit is set by the F35.
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The DNP MESSAGE FRAGMENT SIZE setting determines the size, in bytes, at which message fragmentation occurs. Large
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays,
check the “DNP Points Lists” F35 web page to view the points lists. This page can be viewed with a web
NOTE
browser by entering the F35 IP address to access the F35 “Main Menu”, then by selecting the “Device Infor-
mation Menu” > “DNP Points Lists” menu item.
The DNP OBJECT N DEFAULT VARIATION settings allow the user to select the DNP default variation number for object types 1,
2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation response when variation 0 is requested and/or in
class 0, 1, 2, or 3 scans. Refer to the DNP Implementation section in Appendix E for additional details.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the F35 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
master can operate a single point for both trip and close, or raise and lower, operations. The F35 can be configured to sup-
port paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED CONTROL
POINTS setting allows configuration of from 0 to 32 binary output paired controls. Points not configured as paired operate on
a one-to-one basis.

The DNP ADDRESS setting is the DNP slave address. This number identifies the F35 on a DNP communications link. Each
DNP slave should be assigned a unique address.

5-18 F35 Multiple Feeder Management Relay GE Multilin

 5 SETTINGS 5.2 PRODUCT SETUP

The F35 Multiple Feeder Management Relay is provided with optional IEC 61850 communications capa-
bility. This feature is specified as a software option at the time of ordering. Refer to the Ordering section of
chapter 2 for additional details. The IEC 61850 protocol feature are not available if CPU Type E is ordered.

The F35 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported
over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The F35 operates as an IEC 61850
server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
The REMOTE I/O TRANSFER METHOD selects the method used to transfer remote input/output data. This can be either IEC
61850 GSSE, IEC 61850 GOOSE, or none (remote inputs/outputs disabled). GOOSE messages are more efficient and can
make use of Ethernet priority tagging and virtual LAN functionality. All relays exchanging remote input/output data must be
set to the same transfer method.
The DEFAULT GSSE/GOOSE UPDATE TIME sets the time between GSSE or GOOSE messages when there are no remote out-
put state changes to be sent. When remote output data changes, GSSE or GOOSE messages are sent immediately. This
setting controls the steady-state ‘heartbeat’ time interval.
The GOOSE TRANSMIT VLAN PRIORITY setting indicates the Ethernet priority of GOOSE messages. This allows GOOSE
messages to have higher priority than other Ethernet data. The GOOSE TRANSMIT ETYPE APPID setting allows the selection
of a specific application ID for each GOOSE sending device. This value can be left at its default if the feature is not
required. Both the GOOSE TRANSMIT VLAN PRIORITY and GOOSE TRANSMIT ETYPE APPID settings are required by IEC 61850.
The LD NAME setting represents the MMS domain name (IEC 61850 logical device) where all IEC/MMS logical nodes are
located. The IEC/MMS TCP PORT NUMBER setting allows the user to change the TCP port number for MMS connections. The
INCLUDE NON-IEC DATA setting determines whether or not the “UR” MMS domain will be available. This domain contains a
large number of UR-series specific data items that are not available in the IEC 61850 logical nodes. This data does not fol-
low the IEC 61850 naming conventions. For communications schemes that strictly follow the IEC 61850 standard, this set- 5
ting should be “Disabled”.
The NUMBER OF STATUS POINTS IN GGIO1 setting determines the number of “Ind” (single point status indications) that are
instantiated in the GGIO1 logical node. The indication points in GGIO1 are mapped to FlexStates in the F35. These Flex-
States allow user-customized access to the FlexLogic™ operand states in the relay.
The SERVER SCANNING feature should be set to “Disabled” when IEC 61850 client/server functionality is not required. IEC
61850 has two modes of functionality: GOOSE/GSSE inter-device communication and client/server communication. If the
GOOSE/GSSE functionality is required without the IEC 61850 client server feature, then server scanning can be disabled
to increase CPU resources. When server scanning is disabled, there will be not updated to the IEC 61850 logical node sta-
tus values in the F35. Clients will still be able to connect to the server (F35 relay), but most data values will not be updated.
This setting does not affect GOOSE/GSSE operation.
Changes to the LD NAME, NUMBER OF STATUS POINTS IN GGIO1, and SERVER SCANNING settings will not take effect
until the F35 is restarted.
NOTE

The IEC 61850 logical node name prefix settings are used to create name prefixes to uniquely identify each logical node.
For example, the logical node “PTOC1” may have the name prefix “abc”. The full logical node name will then be
“abcMMXU1”. Valid characters for the logical node name prefixes are upper and lowercase letters, numbers, and the
underscore (_) character, and the first character in the prefix must be a letter. This conforms to the IEC 61850 standard.
The MMXU deadband settings represent the deadband values used to determine when the update the MMXU “mag” and
“cVal” values from the associated “instmag” and “instcVal” values. The “mag” and “cVal” values are used for the IEC 61850
buffered and unbuffered reports. These settings correspond to the associated “db” data items in the CF functional con-
straint of the MMXU logical node, as per the IEC 61850 standard. According to IEC 61850-7-3, the db value “shall repre-
sent the percentage of difference between the maximum and minimum in units of 0.00%”. Thus, it is important to know the
maximum value for each MMXU measured quantity, since this represents the 100.00% value for the deadband.
The minimum value for all quantities is 0; the maximum values are as follows:
phase current: 46 × phase CT primary setting
neutral current: 46 × ground CT primary setting
voltage: 275 × VT ratio setting

frequency: 90 Hz
power factor: 2
The GGIO2 control configuration settings are used to set the control model for each input. The available choices are “0”
(status only), “1” (direct control), and “2” (SBO with normal security). The GGIO2 control points are used to control the F35
virtual inputs.
Since GSSE/GOOSE messages are multicast ethernet by specification, they will not usually be forwarded by net-
work routers. However, GOOSE messages may be fowarded by routers if the router has been configured for VLAN

The F35 supports the IEC 60870-5-104 protocol. The F35 can be used as an IEC 60870-5-104 slave device connected to a
maximum of two masters (usually either an RTU or a SCADA master station). Since the F35 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the F35 at one time.
The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containing
M_ME_NC_1 analog data. These settings group the F35 analog data into types: current, voltage, power, energy, and other.
Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the F35 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLD set-
ting should be set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of mea-
sured value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the F35, the default thresholds will be in effect.
The IEC 60870-5-104 and DNP protocols can not be used at the same time. When the IEC 60870-5-104 FUNC-
TION setting is set to “Enabled”, the DNP protocol will not be operational. When this setting is changed it
NOTE
will not become active until power to the relay has been cycled (Off/On).

The F35 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the F35 can obtain clock time over
an Ethernet network. The F35 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver to provide an accurate time. Both unicast and broadcast SNTP are supported.
If SNTP functionality is enabled at the same time as IRIG-B, the IRIG-B signal provides the time value to the F35 clock for
as long as a valid signal is present. If the IRIG-B signal is removed, the time obtained from the SNTP server is used. If
either SNTP or IRIG-B is enabled, the F35 clock value cannot be changed using the front panel keypad.
To use SNTP in unicast mode, SNTP SERVER IP ADDR must be set to the SNTP/NTP server IP address. Once this address is
set and SNTP FUNCTION is “Enabled”, the F35 attempts to obtain time values from the SNTP/NTP server. Since many time
values are obtained and averaged, it generally takes three to four minutes until the F35 clock is closely synchronized with
the SNTP/NTP server. It may take up to two minutes for the F35 to signal an SNTP self-test error if the server is offline.
To use SNTP in broadcast mode, set the SNTP SERVER IP ADDR setting to “0.0.0.0” and SNTP FUNCTION to “Enabled”. The
F35 then listens to SNTP messages sent to the “all ones” broadcast address for the subnet. The F35 waits up to eighteen
minutes (>1024 seconds) without receiving an SNTP broadcast message before signaling an SNTP self-test error.

The F35 Multiple Feeder Management Relay is provided with optional Ethernet Global Data (EGD) com-
munications capability. This feature is specified as a software option at the time of ordering. Refer to the
Ordering section of chapter 2 for additional details. The Ethernet Global Data (EGD) protocol feature is not
available if CPU Type E is ordered.

The relay supports one fast Ethernet Global Data (EGD) exchange and two slow EGD exchanges. There are 20 data items
in the fast-produced EGD exchange and 50 data items in each slow-produced exchange.
Ethernet Global Data (EGD) is a suite of protocols used for the real-time transfer of data for display and control purposes.
The relay can be configured to ‘produce’ EGD data exchanges, and other devices can be configured to ‘consume’ EGD
data exchanges. The number of produced exchanges (up to three), the data items in each exchange (up to 50), and the
exchange production rate can be configured.
EGD cannot be used to transfer data between UR-series relays. The relay supports EGD production only. An EGD
exchange will not be transmitted unless the destination address is non-zero, and at least the first data item address is set to
a valid Modbus register address. Note that the default setting value of “0” is considered invalid.

Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are described below:
• EXCH 1 DESTINATION: This setting specifies the destination IP address of the produced EGD exchange. This is usu-
ally unicast or broadcast.
• EXCH 1 DATA RATE: This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms,
the exchange data will be updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data will be
updated and sent once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a
setting range of 500 to 1000 ms.
• EXCH 1 DATA ITEM 1 to 20/50: These settings specify the data items that are part of this EGD exchange. Almost any
data from the F35 memory map can be configured to be included in an EGD exchange. The settings are the starting
Modbus register address for the data item in decimal format. Refer to Appendix B for the complete Modbus memory
map. Note that the Modbus memory map displays shows addresses in hexadecimal format; as such, it will be neces-
sary to convert these values to decimal format before entering them as values for these setpoints.
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (e.g. 32 bit integers and floating point values), only the first
Modbus address is required. The EGD exchange configured with these settings contains the data items up to the first
setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid Modbus
addresses and the fourth is 0, the produced EGD exchange will contain three data items.

 5 SETTINGS 5.2 PRODUCT SETUP

The fault report stores data, in non-volatile memory, pertinent to an event when triggered. The captured data contained in
the FaultReport.txt file includes:
• Fault report number
• Name of the relay, programmed by the user
• Firmware revision of the relay
• Date and time of trigger
• Name of trigger (specific operand)
• Line/Feeder ID via the name of a configured signal source
• Active setting group at the time of trigger
• Pre-fault current and voltage phasors (one-quarter cycle before the trigger)
• Fault current and voltage phasors (three-quarter cycle after the trigger)
• Elements operated at the time of triggering
• Events: 9 before trigger and 7 after trigger (only available via the relay webpage)
• Fault duration times for each breaker (created by the Breaker Arcing Current feature)
The fault locator does not report fault type or location if the source VTs are connected in the Delta configuration.

NOTE

The captured data also includes the fault type and the distance to the fault location, as well as the reclose shot number
(when applicable) The Fault Locator does not report fault type or location if the source VTs are connected in the Delta con-
figuration. To include fault duration times in the fault report, the user must enable and configure Breaker Arcing Current fea-
ture for each of the breakers. Fault duration is reported on a per-phase basis.
5
The trigger can be any FlexLogic™ operand, but in most applications it is expected to be the same operand, usually a vir-
tual output, that is used to drive an output relay to trip a breaker. To prevent the overwriting of fault events, the disturbance
detector should not be used to trigger a fault report. A FAULT RPT TRIG event is automatically created when the report is
triggered.
If a number of protection elements are ORed to create a fault report trigger, the first operation of any element causing the
OR gate output to become high triggers a fault report. However, If other elements operate during the fault and the first oper-
ated element has not been reset (the OR gate output is still high), the fault report is not triggered again. Considering the
reset time of protection elements, there is very little chance that fault report can be triggered twice in this manner. As the
fault report must capture a usable amount of pre and post-fault data, it can not be triggered faster than every 20 ms.
Each fault report is stored as a file; the relay capacity is fifteen (15) files. An sixteenth (16th) trigger overwrites the oldest
file. Individual fault report features store their files in the same memory space. The sixteenth report will overwrite the first
one regardless which fault report feature produced the sixteenth and the first records.
The EnerVista UR Setup software is required to view all captured data. The relay faceplate display can be used to view the
date and time of trigger, the fault type, the distance location of the fault, and the reclose shot number.
The FAULT REPORT 1(5) SOURCE setting selects the source for input currents and voltages and disturbance detection. The
FAULT 1(5) REPORT TRIG setting assigns the FlexLogic™ operand representing the protection element/elements requiring
operational fault location calculations. The distance to fault calculations are initiated by this signal. The FAULT REPORT 1(5)
Z1 MAG and FAULT REPORT 1(5) Z0 MAG impedances are entered in secondary ohms.

A new record may automatically overwrite an older record if TRIGGER MODE is set to “Automatic Overwrite”.
Set the TRIGGER POSITION to a percentage of the total buffer size (e.g. 10%, 50%, 75%, etc.). A trigger position of 25% con-
sists of 25% pre- and 75% post-trigger data. The TRIGGER SOURCE is always captured in oscillography and may be any
FlexLogic™ parameter (element state, contact input, virtual output, etc.). The relay sampling rate is 64 samples per cycle.
The AC INPUT WAVEFORMS setting determines the sampling rate at which AC input signals (i.e. current and voltage) are
stored. Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling
rate of the relay which is always 64 samples per cycle, i.e. it has no effect on the fundamental calculations of the device.
When changes are made to the oscillography settings, all existing oscillography records will be CLEARED.

parameters available in a given relay are dependent on: (a) the type of relay, (b) the type and number of CT/VT hardware 5
modules installed, and (c) the type and number of Analog Input hardware modules installed. Upon startup, the relay will
automatically prepare the parameter list. A list of all possible analog metering actual value parameters is presented in
Appendix A: FlexAnalog Parameters. The parameter index number shown in any of the tables is used to expedite the
selection of the parameter on the relay display. It can be quite time-consuming to scan through the list of parameters via the
relay keypad/display - entering this number via the relay keypad will cause the corresponding parameter to be displayed.
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB desig-
nates the IB signal on Terminal 2 of the CT/VT module in slot F. If there are no CT/VT modules and Analog Input modules,
no analog traces will appear in the file; only the digital traces will appear.
The source harmonic indices appear as oscillography analog channels numbered from 0 to 23. These correspond
directly to the to the 2nd to 25th harmonics in the relay as follows:
NOTE
Analog channel 0 ↔ 2nd harmonic
Analog channel 1 ↔ 3rd harmonic

The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data may

5 be downloaded to EnerVista UR Setup and displayed with parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, meaning that the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. Exam-
ple storage capacities for a system frequency of 60 Hz are shown in the following table.

The relay measures current demand on each phase, and three-phase demand for real, reactive, and apparent power. Cur-
rent and Power methods can be chosen separately for the convenience of the user. Settings are provided to allow the user
to emulate some common electrical utility demand measuring techniques, for statistical or control purposes. If the CRNT
DEMAND METHOD is set to "Block Interval" and the DEMAND TRIGGER is set to “Off”, Method 2 is used (see below). If
DEMAND TRIGGER is assigned to any other FlexLogic™ operand, Method 2a is used (see below).

The relay can be set to calculate demand by any of three methods as described below:
CALCULATION METHOD 1: THERMAL EXPONENTIAL
This method emulates the action of an analog peak recording thermal demand meter. The relay measures the quantity
(RMS current, real power, reactive power, or apparent power) on each phase every second, and assumes the circuit quan-
tity remains at this value until updated by the next measurement. It calculates the 'thermal demand equivalent' based on the
following equation:
– kt
d(t) = D(1 – e ) (EQ 5.6)

where: d = demand value after applying input quantity for time t (in minutes)
D = input quantity (constant), and k = 2.3 / thermal 90% response time.

The 90% thermal response time characteristic of 15 minutes is illustrated below. A setpoint establishes the time to reach
90% of a steady-state value, just as the response time of an analog instrument. A steady state value applied for twice the
response time will indicate 99% of the value.

Figure 5–2: THERMAL DEMAND CHARACTERISTIC

CALCULATION METHOD 2: BLOCK INTERVAL
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the programmed demand time interval, starting daily at 00:00:00 (i.e. 12:00 am). The 1440 minutes per day is divided into
the number of blocks as set by the programmed time interval. Each new value of demand becomes available at the end of
each time interval.
CALCULATION METHOD 2a: BLOCK INTERVAL (with Start Demand Interval Logic Trigger)
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the interval between successive Start Demand Interval logic input pulses. Each new value of demand becomes available at
the end of each pulse. Assign a FlexLogic™ operand to the DEMAND TRIGGER setting to program the input for the new
demand interval pulses.
If no trigger is assigned in the DEMAND TRIGGER setting and the CRNT DEMAND METHOD is "Block Interval", use cal-
5 culating method #2. If a trigger is assigned, the maximum allowed time between 2 trigger signals is 60 minutes. If
NOTE
no trigger signal appears within 60 minutes, demand calculations are performed and available and the algorithm
resets and starts the new cycle of calculations. The minimum required time for trigger contact closure is 20 μs.
CALCULATION METHOD 3: ROLLING DEMAND
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the programmed demand time interval, in the same way as Block Interval. The value is updated every minute and indicates
the demand over the time interval just preceding the time of update.

When enabled, the LED Test can be initiated from any digital input or user-programmable condition such as user-program-
mable pushbutton. The control operand is configured under the LED TEST CONTROL setting. The test covers all LEDs,
including the LEDs of the optional user-programmable pushbuttons.
The test consists of three stages.
Stage 1: All 62 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is “burned”. This stage
lasts as long as the control input is on, up to a maximum of 1 minute. After 1 minute, the test will end.
Stage 2: All the LEDs are turned off, and then one LED at a time turns on for 1 second, then back off. The test routine
starts at the top left panel, moving from the top to bottom of each LED column. This test checks for hardware failures
that lead to more than one LED being turned on from a single logic point. This stage can be interrupted at any time.
Stage 3: All the LEDs are turned on. One LED at a time turns off for 1 second, then back on. The test routine starts at
the top left panel moving from top to bottom of each column of the LEDs. This test checks for hardware failures that
lead to more than one LED being turned off from a single logic point. This stage can be interrupted at any time.
When testing is in progress, the LEDs are controlled by the test sequence, rather than the protection, control, and monitor-
ing features. However, the LED control mechanism accepts all the changes to LED states generated by the relay and
stores the actual LED states (On or Off) in memory. When the test completes, the LEDs reflect the actual state resulting
from relay response during testing. The Reset pushbutton will not clear any targets when the LED Test is in progress. 5
A dedicated FlexLogic™ operand, LED TEST IN PROGRESS, is set for the duration of the test. When the test sequence is ini-
tiated, the LED Test Initiated event is stored in the Event Recorder.
The entire test procedure is user-controlled. In particular, Stage 1 can last as long as necessary, and Stages 2 and 3 can be
interrupted. The test responds to the position and rising edges of the control input defined by the LED TEST CONTROL set-
ting. The control pulses must last at least 250 ms to take effect. The following diagram explains how the test is executed.

Control pushbuttons are not typically used for critical operations and are not protected by the control password. However,
by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.
Each control pushbutton asserts its own FlexLogic™ operand, CONTROL PUSHBTN 1(7) ON. These operands should be
configured appropriately to perform the desired function. The operand remains asserted as long as the pushbutton is
pressed and resets when the pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton
manipulation will be recognized by various features that may use control pushbuttons as inputs.
An event is logged in the Event Record (as per user setting) when a control pushbutton is pressed; no event is logged when
the pushbutton is released. The faceplate keys (including control keys) cannot be operated simultaneously – a given key
must be released before the next one can be pressed.

Figure 5–6: USER-PROGRAMMABLE PUSHBUTTONS

Each pushbutton asserts its own On and Off FlexLogic™ operands, respectively. FlexLogic™ operands should be used to
program desired pushbutton actions. The operand names are PUSHBUTTON 1 ON and PUSHBUTTON 1 OFF.
A pushbutton may be programmed to latch or self-reset. An indicating LED next to each pushbutton signals the present sta-
tus of the corresponding "On" FlexLogic™ operand. When set to "Latched", the state of each pushbutton is stored in non-
volatile memory which is maintained during any supply power loss.
Pushbuttons states can be logged by the Event Recorder and displayed as target messages. User-defined messages can
also be associated with each pushbutton and displayed when the pushbutton is ON.
• PUSHBUTTON 1 FUNCTION: This setting selects the characteristic of the pushbutton. If set to “Disabled”, the push-
button is deactivated and the corresponding FlexLogic™ operands (both “On” and “Off”) are de-asserted. If set to
“Self-reset”, the control logic of the pushbutton asserts the “On” corresponding FlexLogic™ operand as long as the
pushbutton is being pressed. As soon as the pushbutton is released, the FlexLogic™ operand is de-asserted. The
“Off” operand is asserted/de-asserted accordingly.
If set to “Latched”, the control logic alternates the state of the corresponding FlexLogic™ operand between “On” and
“Off” on each push of the button. When operating in “Latched” mode, FlexLogic™ operand states are stored in non-vol-
atile memory. Should power be lost, the correct pushbutton state is retained upon subsequent power up of the relay.

status is implied to be “Off” upon its release. All user text messaging durations for the pushbuttons are configured with
the PRODUCT SETUP DISPLAY PROPERTIES FLASH MESSAGE TIME setting.

• PUSHBTN 1 DROP-OUT TIME: This setting specifies a drop-out time delay for a pushbutton in the self-reset mode. A
typical applications for this setting is providing a select-before-operate functionality. The selecting pushbutton should
have the drop-out time set to a desired value. The operating pushbutton should be logically ANDed with the selecting
pushbutton in FlexLogic™. The selecting pushbutton LED remains on for the duration of the drop-out time, signaling
the time window for the intended operation.
For example, consider a relay with the following settings: PUSHBTN 1 ID TEXT: “AUTORECLOSER”, PUSHBTN 1 ON TEXT:
“DISABLED - CALL 2199", and PUSHBTN 1 OFF TEXT: “ENABLED”. When Pushbutton 1 changes its state to the “On” posi-
tion, the following AUTOCLOSER DISABLED – Call 2199 message is displayed: When Pushbutton 1 changes its state to the
“Off” position, the message will change to AUTORECLOSER ENABLED.
User-programmable pushbuttons require a type HP relay faceplate. If an HP-type faceplate was ordered sepa-
rately, the relay order code must be changed to indicate the HP faceplate option. This can be done via EnerVista

which are of interest to the user are available in a minimum number of Modbus registers.
The state bits may be read out in the “Flex States” register array beginning at Modbus address 900 hex. 16 states are
packed into each register, with the lowest-numbered state in the lowest-order bit. There are 16 registers in total to accom-
modate the 256 state bits.

This menu provides a mechanism for manually creating up to 16 user-defined information displays in a convenient viewing
sequence in the USER DISPLAYS menu (between the TARGETS and ACTUAL VALUES top-level menus). The sub-menus facili-
tate text entry and Modbus Register data pointer options for defining the User Display content.
Once programmed, the user-definable displays can be viewed in two ways.
• KEYPAD: Use the Menu key to select the USER DISPLAYS menu item to access the first user-definable display (note
that only the programmed screens are displayed). The screens can be scrolled using the Up and Down keys. The dis-
play disappears after the default message time-out period specified by the PRODUCT SETUP DISPLAY PROPERTIES
DEFAULT MESSAGE TIMEOUT setting.

• USER-PROGRAMMABLE CONTROL INPUT: The user-definable displays also respond to the INVOKE AND SCROLL
setting. Any FlexLogic™ operand (in particular, the user-programmable pushbutton operands), can be used to navi-
5 gate the programmed displays.
On the rising edge of the configured operand (such as when the pushbutton is pressed), the displays are invoked by
showing the last user-definable display shown during the previous activity. From this moment onward, the operand
acts exactly as the Down key and allows scrolling through the configured displays. The last display wraps up to the first
one. The INVOKE AND SCROLL input and the Down keypad key operate concurrently.
When the default timer expires (set by the DEFAULT MESSAGE TIMEOUT setting), the relay will start to cycle through the
user displays. The next activity of the INVOKE AND SCROLL input stops the cycling at the currently displayed user dis-
play, not at the first user-defined display. The INVOKE AND SCROLL pulses must last for at least 250 ms to take effect.

Any existing system display can be automatically copied into an available user display by selecting the existing display and
pressing the key. The display will then prompt ADD TO USER DISPLAY LIST?. After selecting “Yes”, a message indi-
cates that the selected display has been added to the user display list. When this type of entry occurs, the sub-menus are
automatically configured with the proper content – this content may subsequently be edited.
This menu is used to enter user-defined text and/or user-selected Modbus-registered data fields into the particular user
display. Each user display consists of two 20-character lines (top and bottom). The tilde (~) character is used to mark the
start of a data field - the length of the data field needs to be accounted for. Up to 5 separate data fields (ITEM 1(5)) can be
entered in a user display - the nth tilde (~) refers to the nth item.
A User Display may be entered from the faceplate keypad or the EnerVista UR Setup interface (preferred for convenience).
The following procedure shows how to enter text characters in the top and bottom lines from the faceplate keypad:
1. Select the line to be edited.
2. Press the key to enter text edit mode.
3. Use either Value key to scroll through the characters. A space is selected like a character.
4. Press the key to advance the cursor to the next position.
5. Repeat step 3 and continue entering characters until the desired text is displayed.
6. The key may be pressed at any time for context sensitive help information.
7. Press the key to store the new settings.
To enter a numerical value for any of the 5 items (the decimal form of the selected Modbus address) from the faceplate key-
pad, use the number keypad. Use the value of ‘0’ for any items not being used. Use the key at any selected system
display (setting, actual value, or command) which has a Modbus address, to view the hexadecimal form of the Modbus
address, then manually convert it to decimal form before entering it (EnerVista UR Setup usage conveniently facilitates this
conversion). 5
Use the key to go to the user displays menu to view the user-defined content. The current user displays will show in
sequence, changing every 4 seconds. While viewing a user display, press the key and then select the ‘Yes” option
to remove the display from the user display list. Use the key again to exit the user displays menu.

Direct inputs/outputs are intended for exchange of status information (inputs and outputs) between UR-series relays con-
nected directly via Type-7 digital communications cards. The mechanism is very similar to IEC 61850 GSSE, except that
communications takes place over a non-switchable isolated network and is optimized for speed. On Type 7 cards that sup-
port two channels, direct output messages are sent from both channels simultaneously. This effectively sends direct output
messages both ways around a ring configuration. On Type 7 cards that support one channel, direct output messages are
sent only in one direction. Messages will be resent (forwarded) when it is determined that the message did not originate at
the receiver.
Direct output message timing is similar to GSSE message timing. Integrity messages (with no state changes) are sent at
least every 1000 ms. Messages with state changes are sent within the main pass scanning the inputs and asserting the
outputs unless the communication channel bandwidth has been exceeded. Two Self-Tests are performed and signaled by
the following FlexLogic™ operands:
1. DIRECT RING BREAK (direct input/output ring break). This FlexLogic™ operand indicates that direct output messages
sent from a UR-series relay are not being received back by the relay.
2. DIRECT DEVICE 1(16) OFF (direct device offline). This FlexLogic™ operand indicates that direct output messages from
at least one direct device are not being received.
Direct input/output settings are similar to remote input/output settings. The equivalent of the remote device name strings for
direct inputs/outputs is the DIRECT OUTPUT DEVICE ID. The DIRECT OUTPUT DEVICE ID identifies the relay in all direct output
messages. All UR-series IEDs in a ring should have unique numbers assigned. The IED ID is used to identify the sender of
the direct input/output message.
If the direct input/output scheme is configured to operate in a ring (DIRECT I/O RING CONFIGURATION: “Yes”), all direct output
messages should be received back. If not, the Direct Input/Output Ring Break self-test is triggered. The self-test error is sig-
naled by the DIRECT RING BREAK FlexLogic™ operand.
Select the DIRECT I/O DATA RATE to match the data capabilities of the communications channel. Back-to-back connections of
the local relays configured with the 7A, 7B, 7C, 7D, 7H, 7I, 7J, 7K, 72 and 73 fiber optic communication cards may be set to
128 kbps. For local relays configured with all other communication cards (i.e. 7E, 7F, 7G, 7L, 7M, 7N, 7P, 7R, 7S, 7T, 7W,
74, 75, 76 and 77), the baud rate will be set to 64 kbps. All IEDs communicating over direct inputs/outputs must be set to

 5 SETTINGS 5.2 PRODUCT SETUP

the same data rate. UR-series IEDs equipped with dual-channel communications cards apply the same data rate to both
channels. Delivery time for direct input/output messages is approximately 0.2 of a power system cycle at 128 kbps and 0.4
of a power system cycle at 64 kbps, per each ‘bridge’.
The G.703 and RS422 modules are fixed at 64 kbps only. The SETTINGS PRODUCT SETUP DIRECT I/O
setting is not applicable to these modules.
DIRECT I/O DATA RATE
NOTE

The DIRECT I/O CHANNEL CROSSOVER setting applies to F35s with dual-channel communication cards and allows crossing
over messages from Channel 1 to Channel 2. This places all UR-series IEDs into one direct input/output network regard-
less of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input/output configuration. Please refer to the
Inputs/Outputs section in this chapter for information on configuring FlexLogic™ operands (flags, bits) to be exchanged.
EXAMPLE 1: EXTENDING THE INPUT/OUTPUT CAPABILITIES OF A UR-SERIES RELAY
Consider an application that requires additional quantities of digital inputs and/or output contacts and/or lines of program-
mable logic that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series
IED, such as the C30, to satisfy the additional input/output and programmable logic requirements. The two IEDs are con-
nected via single-channel digital communication cards as shown in the figure below.

DIRECT I/O DATA RATE: "128 kbps"

UR IED 2: DIRECT OUTPUT DEVICE ID: "2"

DIRECT I/O RING CONFIGURATION: "Yes"
DIRECT I/O DATA RATE: "128 kbps"

The message delivery time is about 0.2 of power cycle in both ways (at 128 kbps); i.e., from Device 1 to Device 2, and from
Device 2 to Device 1. Different communications cards can be selected by the user for this back-to-back connection (fiber,
G.703, or RS422).
EXAMPLE 2: INTERLOCKING BUSBAR PROTECTION
A simple interlocking busbar protection scheme could be accomplished by sending a blocking signal from downstream
devices, say 2, 3, and 4, to the upstream device that monitors a single incomer of the busbar, as shown below.

Message delivery time is approximately 0.2 of power system cycle (at 128 kbps) times number of ‘bridges’ between the ori-
gin and destination. Dual-ring configuration effectively reduces the maximum ‘communications distance’ by a factor of two.
In this configuration the following delivery times are expected (at 128 kbps) if both rings are healthy:
5 IED 1 to IED 2: 0.2 of power system cycle; IED 1 to IED 3: 0.4 of power system cycle;
IED 1 to IED 4: 0.2 of power system cycle; IED 2 to IED 3: 0.2 of power system cycle;
IED 2 to IED 4: 0.4 of power system cycle; IED 3 to IED 4: 0.2 of power system cycle
If one ring is broken (say TX2/RX2) the delivery times are as follows:
IED 1 to IED 2: 0.2 of power system cycle; IED 1 to IED 3: 0.4 of power system cycle;
IED 1 to IED 4: 0.6 of power system cycle; IED 2 to IED 3: 0.2 of power system cycle;
IED 2 to IED 4: 0.4 of power system cycle; IED 3 to IED 4: 0.2 of power system cycle
A coordinating timer for this bus protection scheme could be selected to cover the worst case scenario (0.4 of power sys-
tem cycle). Upon detecting a broken ring, the coordination time should be adaptively increased to 0.6 of power system
cycle. The complete application requires addressing a number of issues such as failure of both the communications rings,
failure or out-of-service conditions of one of the relays, etc. Self-monitoring flags of the direct inputs/outputs feature would
be primarily used to address these concerns.

IED 2 to IED 3: 0.2 of power system cycle
In the above scheme, IEDs 1 and 3 do not communicate directly. IED 2 must be configured to forward the messages as
explained in the Inputs/Outputs section. A blocking pilot-aided scheme should be implemented with more security and, ide-
ally, faster message delivery time. This could be accomplished using a dual-ring configuration as shown below. 5

IED 2 to IED 3: 0.2 of power system cycle
The two communications configurations could be applied to both permissive and blocking schemes. Speed, reliability and
cost should be taken into account when selecting the required architecture.

The F35 checks integrity of the incoming direct input/output messages using a 32-bit CRC. The CRC Alarm function is
available for monitoring the communication medium noise by tracking the rate of messages failing the CRC check. The
monitoring function counts all incoming messages, including messages that failed the CRC check. A separate counter adds
up messages that failed the CRC check. When the failed CRC counter reaches the user-defined level specified by the CRC
ALARM CH1 THRESHOLD setting within the user-defined message count CRC ALARM 1 CH1 COUNT, the DIR IO CH1 CRC ALARM
FlexLogic™ operand is set.
When the total message counter reaches the user-defined maximum specified by the CRC ALARM CH1 MESSAGE COUNT set-
ting, both the counters reset and the monitoring process is restarted.
The operand shall be configured to drive an output contact, user-programmable LED, or selected communication-based
output. Latching and acknowledging conditions - if required - should be programmed accordingly.

5 The CRC Alarm function is available on a per-channel basis. The total number of direct input/output messages that failed
the CRC check is available as the ACTUAL VALUES STATUS DIRECT INPUTS CRC FAIL COUNT CH1(2) actual value.

• Message Count and Length of the Monitoring Window: To monitor communications integrity, the relay sends 1
message per second (at 64 kbps) or 2 messages per second (128 kbps) even if there is no change in the direct out-
puts. For example, setting the CRC ALARM CH1 MESSAGE COUNT to “10000”, corresponds a time window of about 160
minutes at 64 kbps and 80 minutes at 128 kbps. If the messages are sent faster as a result of direct outputs activity, the
monitoring time interval will shorten. This should be taken into account when determining the CRC ALARM CH1 MESSAGE
COUNT setting. For example, if the requirement is a maximum monitoring time interval of 10 minutes at 64 kbps, then
the CRC ALARM CH1 MESSAGE COUNT should be set to 10 × 60 × 1 = 600.
• Correlation of Failed CRC and Bit Error Rate (BER): The CRC check may fail if one or more bits in a packet are cor-
rupted. Therefore, an exact correlation between the CRC fail rate and the BER is not possible. Under certain assump-
tions an approximation can be made as follows. A direct input/output packet containing 20 bytes results in 160 bits of
data being sent and therefore, a transmission of 63 packets is equivalent to 10,000 bits. A BER of 10–4 implies 1 bit
error for every 10,000 bits sent/received. Assuming the best case of only 1 bit error in a failed packet, having 1 failed
packet for every 63 received is about equal to a BER of 10–4.

Xa, where X = {F, M, U} and a = {1, 5}.
See the Introduction to AC Sources section at the beginning of this chapter for additional details.
These settings are critical for all features that have settings dependent on current measurements. When the relay is
5 ordered, the CT module must be specified to include a standard or sensitive ground input. As the phase CTs are connected
in Wye (star), the calculated phasor sum of the three phase currents (IA + IB + IC = Neutral Current = 3Io) is used as the
input for the neutral overcurrent elements. In addition, a zero-sequence (core balance) CT which senses current in all of the
circuit primary conductors, or a CT in a neutral grounding conductor may also be used. For this configuration, the ground
CT primary rating must be entered. To detect low level ground fault currents, the sensitive ground input may be used. In this
case, the sensitive ground CT primary rating must be entered. Refer to Chapter 3 for more details on CT connections.
Enter the rated CT primary current values. For both 1000:5 and 1000:1 CTs, the entry would be 1000. For correct opera-
tion, the CT secondary rating must match the setting (which must also correspond to the specific CT connections used).
The following example illustrates how multiple CT inputs (current banks) are summed as one source current. Given If the
following current banks:
F1: CT bank with 500:1 ratio; F5: CT bank with 1000: ratio; M1: CT bank with 800:1 ratio
The following rule applies:
SRC 1 = F1 + F5 + M1 (EQ 5.7)

1 pu is the highest primary current. In this case, 1000 is entered and the secondary current from the 500:1 ratio CT will be
adjusted to that created by a 1000:1 CT before summation. If a protection element is set up to act on SRC 1 currents, then
a pickup level of 1 pu will operate on 1000 A primary.
The same rule applies for current sums from CTs with different secondary taps (5 A and 1 A).

With VTs installed, the relay can perform voltage measurements as well as power calculations. Enter the PHASE VT F5 CON-
NECTION made to the system as “Wye” or “Delta”. An open-delta source VT connection would be entered as “Delta”. See
the Typical Wiring Diagram in Chapter 3 for details.
The nominal PHASE VT F5 SECONDARY voltage setting is the voltage across the relay input terminals when nominal
voltage is applied to the VT primary.
NOTE
For example, on a system with a 13.8 kV nominal primary voltage and with a 14400:120 volt VT in a Delta connec-
tion, the secondary voltage would be 115, i.e. (13800 / 14400) × 120. For a Wye connection, the voltage value
entered must be the phase to neutral voltage which would be 115 / 3 = 66.4.
On a 14.4 kV system with a Delta connection and a VT primary to secondary turns ratio of 14400:120, the voltage
value entered would be 120, i.e. 14400 / 120.
If the PHASE VT F5 CONNECTION is set to “Delta”, the relay will not calculate voltage harmonics.

The power system NOMINAL FREQUENCY value is used as a default to set the digital sampling rate if the system frequency
cannot be measured from available signals. This may happen if the signals are not present or are heavily distorted. Before
reverting to the nominal frequency, the frequency tracking algorithm holds the last valid frequency measurement for a safe
period of time while waiting for the signals to reappear or for the distortions to decay.
The phase sequence of the power system is required to properly calculate sequence components and power parameters.
The PHASE ROTATION setting matches the power system phase sequence. Note that this setting informs the relay of the
actual system phase sequence, either ABC or ACB. CT and VT inputs on the relay, labeled as A, B, and C, must be con-
nected to system phases A, B, and C for correct operation.
The FREQUENCY AND PHASE REFERENCE setting determines which signal source is used (and hence which AC signal) for
phase angle reference. The AC signal used is prioritized based on the AC inputs that are configured for the signal source:
phase voltages takes precedence, followed by auxiliary voltage, then phase currents, and finally ground current.
For three phase selection, phase A is used for angle referencing ( V ANGLE REF = V A ), while Clarke transformation of the
phase signals is used for frequency metering and tracking ( V FREQUENCY = ( 2V A – V B – V C ) ⁄ 3 ) for better performance dur-
ing fault, open pole, and VT and CT fail conditions.
The phase reference and frequency tracking AC signals are selected based upon the Source configuration, regardless of
whether or not a particular signal is actually applied to the relay.
Phase angle of the reference signal will always display zero degrees and all other phase angles will be relative to this sig-
nal. If the pre-selected reference signal is not measurable at a given time, the phase angles are not referenced.
The phase angle referencing is done via a phase locked loop, which can synchronize independent UR-series relays if they
have the same AC signal reference. These results in very precise correlation of time tagging in the event recorder between
different UR-series relays provided the relays have an IRIG-B connection.
FREQUENCY TRACKING should only be set to "Disabled" in very unusual circumstances; consult the factory for spe-

Six identical source menus are available. The "SRC 1" text can be replaced by with a user-defined name appropriate for the
associated source.
“F”, “M”, and “U” represent the module slot position. The number directly following these letters represents either the first
bank of four channels (1, 2, 3, 4) called “1” or the second bank of four channels (5, 6, 7, 8) called “5” in a particular CT/VT
module. Refer to the Introduction to AC Sources section at the beginning of this chapter for additional details on this con-
cept.
It is possible to select the sum of up to six (6) CTs. The first channel displayed is the CT to which all others will be referred.
For example, the selection “F1+F5” indicates the sum of each phase from channels “F1” and “F5”, scaled to whichever CT
has the higher ratio. Selecting “None” hides the associated actual values.

The approach used to configure the AC sources consists of several steps; first step is to specify the information about each
CT and VT input. For CT inputs, this is the nominal primary and secondary current. For VTs, this is the connection type,
ratio and nominal secondary voltage. Once the inputs have been specified, the configuration for each source is entered,
including specifying which CTs will be summed together.
User Selection of AC Parameters for Comparator Elements:
CT/VT modules automatically calculate all current and voltage parameters from the available inputs. Users must select the
specific input parameters to be measured by every element in the relevant settings menu. The internal design of the ele-
ment specifies which type of parameter to use and provides a setting for source selection. In elements where the parameter
may be either fundamental or RMS magnitude, such as phase time overcurrent, two settings are provided. One setting
specifies the source, the second setting selects between fundamental phasor and RMS.
AC Input Actual Values:
The calculated parameters associated with the configured voltage and current inputs are displayed in the current and volt-
age sections of actual values. Only the phasor quantities associated with the actual AC physical input channels will be dis-
played here. All parameters contained within a configured source are displayed in the sources section of the actual values.
EXAMPLE USE OF SOURCES:
An example of the use of sources, with a relay with CT/VT modules, is shown in the diagram below. A relay could have the
following hardware configuration:

b) FLEXCURVE™ CONFIGURATION WITH ENERVISTA UR SETUP

The EnerVista UR Setup software allows for easy configuration and management of FlexCurves™ and their associated
data points. Prospective FlexCurves™ can be configured from a selection of standard curves to provide the best approxi-
mate fit, then specific data points can be edited afterwards. Alternately, curve data can be imported from a specified file
(.csv format) by selecting the Import Data From EnerVista UR Setup setting.
Curves and data can be exported, viewed, and cleared by clicking the appropriate buttons. FlexCurves™ are customized
by editing the operating time (ms) values at pre-defined per-unit current multiples. Note that the pickup multiples start at
zero (implying the "reset time"), operating time below pickup, and operating time above pickup.

c) RECLOSER CURVE EDITING

Recloser Curve selection is special in that recloser curves can be shaped into a composite curve with a minimum response
time and a fixed time above a specified pickup multiples. There are 41 recloser curve types supported. These definite oper-
ating times are useful to coordinate operating times, typically at higher currents and where upstream and downstream pro-
tective devices have different operating characteristics. The Recloser Curve configuration window shown below appears
when the Initialize From EnerVista UR Setup setting is set to “Recloser Curve” and the Initialize FlexCurve button is clicked.

Multiplier: Scales (multiplies) the curve operating times

Addr: Adds the time specified in this field (in ms) to each
curve operating time value.

Minimum Response Time (MRT): If enabled, the MRT setting

defines the shortest operating time even if the curve suggests
a shorter time at higher current multiples. A composite operating
characteristic is effectively defined. For current multiples lower
than the intersection point, the curve dictates the operating time;
5
otherwise, the MRT does. An information message appears
when attempting to apply an MRT shorter than the minimum
curve time.

High Current Time: Allows the user to set a pickup multiple

from which point onwards the operating time is fixed. This is
normally only required at higher current levels. The HCT Ratio
defines the high current pickup multiple; the HCT defines the
operating time.
842721A1.CDR

Figure 5–14: RECLOSER CURVE INITIALIZATION

Multiplier and Adder settings only affect the curve portion of the characteristic and not the MRT and HCT settings.
The HCT settings override the MRT settings for multiples of pickup greater than the HCT Ratio.

d) EXAMPLE
A composite curve can be created from the GE_111 standard with MRT = 200 ms and HCT initially disabled and then
enabled at 8 times pickup with an operating time of 30 ms. At approximately 4 times pickup, the curve operating time is
equal to the MRT and from then onwards the operating time remains at 200 ms (see below).

842719A1.CDR

Figure 5–15: COMPOSITE RECLOSER CURVE WITH HCT DISABLED

With the HCT feature enabled, the operating time reduces to 30 ms for pickup multiples exceeding 8 times pickup.

842720A1.CDR

Figure 5–16: COMPOSITE RECLOSER CURVE WITH HCT ENABLED

Configuring a composite curve with an increase in operating time at increased pickup multiples is not allowed. If this
is attempted, the EnerVista UR Setup software generates an error message and discards the proposed changes.

 5 SETTINGS 5.4 FLEXLOGIC™

5.4FLEXLOGIC™ 5.4.1 INTRODUCTION TO FLEXLOGIC™

To provide maximum flexibility to the user, the arrangement of internal digital logic combines fixed and user-programmed
parameters. Logic upon which individual features are designed is fixed, and all other logic, from digital input signals through
elements or combinations of elements to digital outputs, is variable. The user has complete control of all variable logic
through FlexLogic™. In general, the system receives analog and digital inputs which it uses to produce analog and digital
outputs. The major sub-systems of a generic UR-series relay involved in this process are shown below.

Figure 5–25: UR ARCHITECTURE OVERVIEW

The states of all digital signals used in the F35 are represented by flags (or FlexLogic™ operands, which are described
later in this section). A digital “1” is represented by a 'set' flag. Any external contact change-of-state can be used to block an
element from operating, as an input to a control feature in a FlexLogic™ equation, or to operate a contact output. The state
of the contact input can be displayed locally or viewed remotely via the communications facilities provided. If a simple
scheme where a contact input is used to block an element is desired, this selection is made when programming the ele-
ment. This capability also applies to the other features that set flags: elements, virtual inputs, remote inputs, schemes, and
human operators.
If more complex logic than presented above is required, it is implemented via FlexLogic™. For example, if it is desired to
have the closed state of contact input H7a and the operated state of the phase undervoltage element block the operation of
the phase time overcurrent element, the two control input states are programmed in a FlexLogic™ equation. This equation
ANDs the two control inputs to produce a ‘virtual output’ which is then selected when programming the phase time overcur-
rent to be used as a blocking input. Virtual outputs can only be created by FlexLogic™ equations.
Traditionally, protective relay logic has been relatively limited. Any unusual applications involving interlocks, blocking, or
supervisory functions had to be hard-wired using contact inputs and outputs. FlexLogic™ minimizes the requirement for
auxiliary components and wiring while making more complex schemes possible.

GE Multilin F35 Multiple Feeder Management Relay 5-57

 5.4 FLEXLOGIC™ 5 SETTINGS

The logic that determines the interaction of inputs, elements, schemes and outputs is field programmable through the use
of logic equations that are sequentially processed. The use of virtual inputs and outputs in addition to hardware is available
internally and on the communication ports for other relays to use (distributed FlexLogic™).
FlexLogic™ allows users to customize the relay through a series of equations that consist of operators and operands. The
operands are the states of inputs, elements, schemes and outputs. The operators are logic gates, timers and latches (with
set and reset inputs). A system of sequential operations allows any combination of specified operands to be assigned as
inputs to specified operators to create an output. The final output of an equation is a numbered register called a virtual out-
put. Virtual outputs can be used as an input operand in any equation, including the equation that generates the output, as a
seal-in or other type of feedback.
A FlexLogic™ equation consists of parameters that are either operands or operators. Operands have a logic state of 1 or 0.
Operators provide a defined function, such as an AND gate or a Timer. Each equation defines the combinations of parame-
ters to be used to set a Virtual Output flag. Evaluation of an equation results in either a 1 (=ON, i.e. flag set) or 0 (=OFF, i.e.
flag not set). Each equation is evaluated at least 4 times every power system cycle.
Some types of operands are present in the relay in multiple instances; e.g. contact and remote inputs. These types of oper-
ands are grouped together (for presentation purposes only) on the faceplate display. The characteristics of the different
types of operands are listed in the table below.

5.4.2 FLEXLOGIC™ RULES

When forming a FlexLogic™ equation, the sequence in the linear array of parameters must follow these general rules:
1. Operands must precede the operator which uses the operands as inputs.
2. Operators have only one output. The output of an operator must be used to create a virtual output if it is to be used as
an input to two or more operators.
3. Assigning the output of an operator to a Virtual Output terminates the equation.
4. A timer operator (e.g. "TIMER 1") or virtual output assignment (e.g. " = Virt Op 1") may only be used once. If this rule is
broken, a syntax error will be declared.

5.4.3 FLEXLOGIC™ EVALUATION

Each equation is evaluated in the order in which the parameters have been entered.
FlexLogic™ provides latches which by definition have a memory action, remaining in the set state after the
set input has been asserted. However, they are volatile; i.e. they reset on the re-application of control
CAUTION
power.
When making changes to settings, all FlexLogic™ equations are re-compiled whenever any new setting
value is entered, so all latches are automatically reset. If it is necessary to re-initialize FlexLogic™ during
testing, for example, it is suggested to power the unit down and then back up.

5.4.4 FLEXLOGIC™ EXAMPLE

This section provides an example of implementing logic for a typical application. The sequence of the steps is quite impor-
tant as it should minimize the work necessary to develop the relay settings. Note that the example presented in the figure
below is intended to demonstrate the procedure, not to solve a specific application situation.
In the example below, it is assumed that logic has already been programmed to produce Virtual Outputs 1 and 2, and is
only a part of the full set of equations used. When using FlexLogic™, it is important to make a note of each Virtual Output
used – a Virtual Output designation (1 to 96) can only be properly assigned once.

Figure 5–26: EXAMPLE LOGIC SCHEME

5 1. Inspect the example logic diagram to determine if the required logic can be implemented with the FlexLogic™ opera-
tors. If this is not possible, the logic must be altered until this condition is satisfied. Once this is done, count the inputs
to each gate to verify that the number of inputs does not exceed the FlexLogic™ limits, which is unlikely but possible. If
the number of inputs is too high, subdivide the inputs into multiple gates to produce an equivalent. For example, if 25
inputs to an AND gate are required, connect Inputs 1 through 16 to AND(16), 17 through 25 to AND(9), and the outputs
from these two gates to AND(2).
Inspect each operator between the initial operands and final virtual outputs to determine if the output from the operator
is used as an input to more than one following operator. If so, the operator output must be assigned as a Virtual Output.
For the example shown above, the output of the AND gate is used as an input to both OR#1 and Timer 1, and must
therefore be made a Virtual Output and assigned the next available number (i.e. Virtual Output 3). The final output
must also be assigned to a Virtual Output as Virtual Output 4, which will be programmed in the contact output section
to operate relay H1 (i.e. Output Contact H1).
Therefore, the required logic can be implemented with two FlexLogic™ equations with outputs of Virtual Output 3 and
Virtual Output 4 as shown below.

2. Prepare a logic diagram for the equation to produce Virtual Output 3, as this output will be used as an operand in the
Virtual Output 4 equation (create the equation for every output that will be used as an operand first, so that when these
operands are required they will already have been evaluated and assigned to a specific Virtual Output). The logic for
Virtual Output 3 is shown below with the final output assigned.

4. Program the FlexLogic™ equation for Virtual Output 3 by translating the logic into available FlexLogic™ parameters.
The equation is formed one parameter at a time until the required logic is complete. It is generally easier to start at the
output end of the equation and work back towards the input, as shown in the following steps. It is also recommended to
list operator inputs from bottom to top. For demonstration, the final output will be arbitrarily identified as parameter 99,
and each preceding parameter decremented by one in turn. Until accustomed to using FlexLogic™, it is suggested that
a worksheet with a series of cells marked with the arbitrary parameter numbers be prepared, as shown below.

5. Following the procedure outlined, start with parameter 99, as follows:
99: The final output of the equation is Virtual Output 3, which is created by the operator "= Virt Op n". This parameter
is therefore "= Virt Op 3."

GE Multilin F35 Multiple Feeder Management Relay 5-65

 5.4 FLEXLOGIC™ 5 SETTINGS

98: The gate preceding the output is an AND, which in this case requires two inputs. The operator for this gate is a 2-
input AND so the parameter is “AND(2)”. Note that FlexLogic™ rules require that the number of inputs to most
types of operators must be specified to identify the operands for the gate. As the 2-input AND will operate on the
two operands preceding it, these inputs must be specified, starting with the lower.
97: This lower input to the AND gate must be passed through an inverter (the NOT operator) so the next parameter is
“NOT”. The NOT operator acts upon the operand immediately preceding it, so specify the inverter input next.
96: The input to the NOT gate is to be contact input H1c. The ON state of a contact input can be programmed to be
set when the contact is either open or closed. Assume for this example the state is to be ON for a closed contact.
The operand is therefore “Cont Ip H1c On”.
95: The last step in the procedure is to specify the upper input to the AND gate, the operated state of digital element 2.
This operand is "DIG ELEM 2 OP".
Writing the parameters in numerical order can now form the equation for VIRTUAL OUTPUT 3:
[95] DIG ELEM 2 OP
[96] Cont Ip H1c On
[97] NOT
[98] AND(2)
[99] = Virt Op 3
It is now possible to check that this selection of parameters will produce the required logic by converting the set of parame-
ters into a logic diagram. The result of this process is shown below, which is compared to the Logic for Virtual Output 3 dia-
gram as a check.

6. Repeating the process described for VIRTUAL OUTPUT 3, select the FlexLogic™ parameters for Virtual Output 4.
99: The final output of the equation is VIRTUAL OUTPUT 4 which is parameter “= Virt Op 4".
98: The operator preceding the output is Timer 2, which is operand “TIMER 2". Note that the settings required for the
timer are established in the timer programming section.
97: The operator preceding Timer 2 is OR #2, a 3-input OR, which is parameter “OR(3)”.
96: The lowest input to OR #2 is operand “Cont Ip H1c On”.
95: The center input to OR #2 is operand “TIMER 1".
94: The input to Timer 1 is operand “Virt Op 3 On".
93: The upper input to OR #2 is operand “LATCH (S,R)”.
92: There are two inputs to a latch, and the input immediately preceding the latch reset is OR #1, a 4-input OR, which
is parameter “OR(4)”.
91: The lowest input to OR #1 is operand “Virt Op 3 On".
90: The input just above the lowest input to OR #1 is operand “XOR(2)”.
89: The lower input to the XOR is operand “DIG ELEM 1 PKP”.
88: The upper input to the XOR is operand “Virt Ip 1 On".
87: The input just below the upper input to OR #1 is operand “Virt Op 2 On".
86: The upper input to OR #1 is operand “Virt Op 1 On".
85: The last parameter is used to set the latch, and is operand “Virt Op 4 On".

7. Now write the complete FlexLogic™ expression required to implement the logic, making an effort to assemble the
equation in an order where Virtual Outputs that will be used as inputs to operators are created before needed. In cases
where a lot of processing is required to perform logic, this may be difficult to achieve, but in most cases will not cause
problems as all logic is calculated at least 4 times per power frequency cycle. The possibility of a problem caused by
sequential processing emphasizes the necessity to test the performance of FlexLogic™ before it is placed in service.
In the following equation, Virtual Output 3 is used as an input to both Latch 1 and Timer 1 as arranged in the order
shown below:

In the expression above, the Virtual Output 4 input to the 4-input OR is listed before it is created. This is typical of a
form of feedback, in this case, used to create a seal-in effect with the latch, and is correct.
8. The logic should always be tested after it is loaded into the relay, in the same fashion as has been used in the past.
Testing can be simplified by placing an "END" operator within the overall set of FlexLogic™ equations. The equations
will then only be evaluated up to the first "END" operator.
The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, and
the "INSERT" and "DELETE" commands can be used to modify equations.

The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined period
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold as
per user's choice.

The FLEXELEMENT 1 +IN setting specifies the first (non-inverted) input to the FlexElement™. Zero is assumed as the input if
this setting is set to “Off”. For proper operation of the element at least one input must be selected. Otherwise, the element
5 will not assert its output operands.
This FLEXELEMENT 1 –IN setting specifies the second (inverted) input to the FlexElement™. Zero is assumed as the input if
this setting is set to “Off”. For proper operation of the element at least one input must be selected. Otherwise, the element
will not assert its output operands. This input should be used to invert the signal if needed for convenience, or to make the
element respond to a differential signal such as for a top-bottom oil temperature differential alarm. The element will not
operate if the two input signals are of different types, for example if one tries to use active power and phase angle to build
the effective operating signal.
The element responds directly to the differential signal if the FLEXELEMENT 1 INPUT MODE setting is set to “Signed”. The ele-
ment responds to the absolute value of the differential signal if this setting is set to “Absolute”. Sample applications for the
“Absolute” setting include monitoring the angular difference between two phasors with a symmetrical limit angle in both
directions; monitoring power regardless of its direction, or monitoring a trend regardless of whether the signal increases of
decreases.
The element responds directly to its operating signal – as defined by the FLEXELEMENT 1 +IN, FLEXELEMENT 1 –IN and FLEX-
ELEMENT 1 INPUT MODE settings – if the FLEXELEMENT 1 COMP MODE setting is set to “Level”. The element responds to the
rate of change of its operating signal if the FLEXELEMENT 1 COMP MODE setting is set to “Delta”. In this case the FLEXELE-
MENT 1 dt UNIT and FLEXELEMENT 1 dt settings specify how the rate of change is derived.

The FLEXELEMENT 1 DIRECTION setting enables the relay to respond to either high or low values of the operating signal. The
following figure explains the application of the FLEXELEMENT 1 DIRECTION, FLEXELEMENT 1 PICKUP and FLEXELEMENT 1 HYS-
TERESIS settings.

The FLEXELEMENT 1 PICKUP setting specifies the operating threshold for the effective operating signal of the element. If set
to “Over”, the element picks up when the operating signal exceeds the FLEXELEMENT 1 PICKUP value. If set to “Under”, the
element picks up when the operating signal falls below the FLEXELEMENT 1 PICKUP value.
The FLEXELEMENT 1 HYSTERESIS setting controls the element dropout. It should be noticed that both the operating signal
and the pickup threshold can be negative facilitating applications such as reverse power alarm protection. The FlexEle-
ment™ can be programmed to work with all analog actual values measured by the relay. The FLEXELEMENT 1 PICKUP set-
ting is entered in per-unit values using the following definitions of the base units:

Table 5–9: FLEXELEMENT™ BASE UNITS

dcmA BASE = maximum value of the DCMA INPUT MAX setting for the two transducers configured
under the +IN and –IN inputs.
FREQUENCY fBASE = 1 Hz
PHASE ANGLE ϕBASE = 360 degrees (see the UR angle referencing convention)
POWER FACTOR PFBASE = 1.00
RTDs BASE = 100°C
SOURCE CURRENT IBASE = maximum nominal primary RMS value of the +IN and –IN inputs
SOURCE ENERGY EBASE = 10000 MWh or MVAh, respectively
(Positive and Negative Watthours,
Positive and Negative Varhours)
SOURCE POWER PBASE = maximum value of VBASE × IBASE for the +IN and –IN inputs
SOURCE VOLTAGE VBASE = maximum nominal primary RMS value of the +IN and –IN inputs

The FLEXELEMENT 1 HYSTERESIS setting defines the pickup–dropout relation of the element by specifying the width of the
5 hysteresis loop as a percentage of the pickup value as shown in the FlexElement™ Direction, Pickup, and Hysteresis dia-
gram.
The FLEXELEMENT 1 DT UNIT setting specifies the time unit for the setting FLEXELEMENT 1 dt. This setting is applicable only if
FLEXELEMENT 1 COMP MODE is set to “Delta”. The FLEXELEMENT 1 DT setting specifies duration of the time interval for the
rate of change mode of operation. This setting is applicable only if FLEXELEMENT 1 COMP MODE is set to “Delta”.
This FLEXELEMENT 1 PKP DELAY setting specifies the pickup delay of the element. The FLEXELEMENT 1 RST DELAY setting
specifies the reset delay of the element.

5.5GROUPED ELEMENTS 5.5.1 OVERVIEW

Each protection element can be assigned up to six different sets of settings according to Setting Group designations 1 to 6.
The performance of these elements is defined by the active Setting Group at a given time. Multiple setting groups allow the
user to conveniently change protection settings for different operating situations (e.g. altered power system configuration,
season of the year). The active setting group can be preset or selected via the SETTING GROUPS menu (see the Control Ele-
ments section later in this chapter). See also the Introduction to Elements section at the beginning of this chapter.

Each of the six Setting Group menus is identical. SETTING GROUP 1 (the default active group) automatically becomes active
if no other group is active (see the Control Elements section for additional details).

a) INVERSE TOC CURVE CHARACTERISTICS

The inverse time overcurrent curves used by the time overcurrent elements are the IEEE, IEC, GE Type IAC, and I2t stan-
dard curve shapes. This allows for simplified coordination with downstream devices. If however, none of these curve
shapes is adequate, FlexCurves™ may be used to customize the inverse time curve characteristics. The Definite Time
curve is also an option that may be appropriate if only simple protection is required.

Table 5–10: OVERCURRENT CURVE TYPES

IEEE IEC GE TYPE IAC OTHER
IEEE Extremely Inv. IEC Curve A (BS142) IAC Extremely Inv. I2t
IEEE Very Inverse IEC Curve B (BS142) IAC Very Inverse FlexCurves™ A, B, C, and D
IEEE Moderately Inv. IEC Curve C (BS142) IAC Inverse Recloser Curves
IEC Short Inverse IAC Short Inverse Definite Time

A time dial multiplier setting allows selection of a multiple of the base curve shape (where the time dial multiplier = 1) with
the curve shape (CURVE) setting. Unlike the electromechanical time dial equivalent, operate times are directly proportional
to the time multiplier (TD MULTIPLIER) setting value. For example, all times for a multiplier of 10 are 10 times the multiplier 1
or base curve values. Setting the multiplier to zero results in an instantaneous response to all current levels above pickup.
Time overcurrent time calculations are made with an internal ‘energy capacity’ memory variable. When this variable indi-
cates that the energy capacity has reached 100%, a time overcurrent element will operate. If less than 100% energy capac-
ity is accumulated in this variable and the current falls below the dropout threshold of 97 to 98% of the pickup value, the
variable must be reduced. Two methods of this resetting operation are available: “Instantaneous” and “Timed”. The “Instan-
taneous” selection is intended for applications with other relays, such as most static relays, which set the energy capacity
directly to zero when the current falls below the reset threshold. The “Timed” selection can be used where the relay must
coordinate with electromechanical relays.

The phase time overcurrent element can provide a desired time-delay operating characteristic versus the applied current or
be used as a simple Definite Time element. The phase current input quantities may be programmed as fundamental phasor
magnitude or total waveform RMS magnitude as required by the application.
Two methods of resetting operation are available: “Timed” and “Instantaneous” (refer to the Inverse TOC Curves Character-
istic sub-section earlier for details on curve setup, trip times and reset operation). When the element is blocked, the time
accumulator will reset according to the reset characteristic. For example, if the element reset characteristic is set to “Instan-
taneous” and the element is blocked, the time accumulator will be cleared immediately.
The PHASE TOC1 PICKUP setting can be dynamically reduced by a voltage restraint feature (when enabled). This is accom-
plished via the multipliers (Mvr) corresponding to the phase-phase voltages of the voltage restraint characteristic curve (see
the figure below); the pickup level is calculated as ‘Mvr’ times the PHASE TOC1 PICKUP setting. If the voltage restraint feature
is disabled, the pickup level always remains at the setting value.

The Neutral Instantaneous Overcurrent element may be used as an instantaneous function with no intentional delay or as a
Definite Time function. The element essentially responds to the magnitude of a neutral current fundamental frequency pha-
sor calculated from the phase currents. A “positive-sequence restraint” is applied for better performance. A small portion 5
(6.25%) of the positive-sequence current magnitude is subtracted from the zero-sequence current magnitude when forming
the operating quantity of the element as follows:
I op = 3 × ( I_0 – K ⋅ I_1 ) where K = 1 ⁄ 16 (EQ 5.16)

The positive-sequence restraint allows for more sensitive settings by counterbalancing spurious zero-sequence currents
resulting from:
• system unbalances under heavy load conditions
• transformation errors of current transformers (CTs) during double-line and three-phase faults
• switch-off transients during double-line and three-phase faults
The positive-sequence restraint must be considered when testing for pickup accuracy and response time (multiple of
pickup). The operating quantity depends on how test currents are injected into the relay (single-phase injection:
I op = 0.9375 ⋅ I injected ; three-phase pure zero-sequence injection: I op = 3 × I injected ).

This element can provide a desired time-delay operating characteristic versus the applied current or be used as a simple
Definite Time element. The ground current input value is the quantity measured by the ground input CT and is the funda-
mental phasor or RMS magnitude. Two methods of resetting operation are available; “Timed” and “Instantaneous” (refer to
the Inverse Time Overcurrent Curve Characteristics section for details). When the element is blocked, the time accumulator
will reset according to the reset characteristic. For example, if the element reset characteristic is set to “Instantaneous” and
the element is blocked, the time accumulator will be cleared immediately.
These elements measure the current that is connected to the ground channel of a CT/VT module. This channel
may be equipped with a standard or sensitive input. The conversion range of a standard channel is from 0.02 to 46
NOTE
times the CT rating. The conversion range of a sensitive channel is from 0.002 to 4.6 times the CT rating.

These protection elements can be used for a variety of applications such as:
Undervoltage Protection: For voltage sensitive loads, such as induction motors, a drop in voltage increases the drawn
5 current which may cause dangerous overheating in the motor. The undervoltage protection feature can be used to either
cause a trip or generate an alarm when the voltage drops below a specified voltage setting for a specified time delay.
Permissive Functions: The undervoltage feature may be used to block the functioning of external devices by operating an
output relay when the voltage falls below the specified voltage setting. The undervoltage feature may also be used to block
the functioning of other elements through the block feature of those elements.
Source Transfer Schemes: In the event of an undervoltage, a transfer signal may be generated to transfer a load from its
normal source to a standby or emergency power source.
The undervoltage elements can be programmed to have a Definite Time delay characteristic. The Definite Time curve oper-
ates when the voltage drops below the pickup level for a specified period of time. The time delay is adjustable from 0 to
600.00 seconds in steps of 10 ms. The undervoltage elements can also be programmed to have an inverse time delay
characteristic. The undervoltage delay setting defines the family of curves shown below.

This element may be used to give a desired time-delay operating characteristic versus the applied fundamental voltage
(phase-to-ground or phase-to-phase for Wye VT connection, or phase-to-phase for Delta VT connection) or as a Definite
Time element. The element resets instantaneously if the applied voltage exceeds the dropout voltage. The delay setting
selects the minimum operating time of the phase undervoltage. The minimum voltage setting selects the operating voltage
below which the element is blocked (a setting of “0” will allow a dead source to be considered a fault condition).

There are three neutral overvoltage elements available. The neutral overvoltage element can be used to detect asymmetri-
cal system voltage condition due to a ground fault or to the loss of one or two phases of the source. The element responds
to the system neutral voltage (3V_0), calculated from the phase voltages. The nominal secondary voltage of the phase volt-
age channels entered under SETTINGS SYSTEM SETUP AC INPUTS VOLTAGE BANK PHASE VT SECONDARY is the
p.u. base used when setting the pickup level.
The Neutral Overvoltage element can provide a time-delayed operating characteristic versus the applied voltage (initialized
from FlexCurves A, B, or C) or be used as a definite time element. The NEUTRAL OV1(3) PICKUP DELAY setting applies only if
the NEUTRAL OV1(3) CURVE setting is “Definite time”. The source assigned to this element must be configured for a phase
VT.
VT errors and normal voltage unbalance must be considered when setting this element. This function requires the VTs to
be Wye connected.

The Setting Groups menu controls the activation/deactivation of up to six possible groups of settings in the GROUPED ELE-
MENTS settings menu. The faceplate ‘Settings In Use’ LEDs indicate which active group (with a non-flashing energized
LED) is in service.
The SETTING GROUPS BLK setting prevents the active setting group from changing when the FlexLogic™ parameter is set to
"On". This can be useful in applications where it is undesirable to change the settings under certain conditions, such as the
breaker being open.
Each GROUP n ACTIVATE ON setting selects a FlexLogic™ operand which, when set, will make the particular setting group
active for use by any grouped element. A priority scheme ensures that only one group is active at a given time – the high-
est-numbered group which is activated by its GROUP n ACTIVATE ON parameter takes priority over the lower-numbered
groups. There is no “activate on” setting for Group 1 (the default active group), because Group 1 automatically becomes
active if no other group is active.
The SETTING GROUP 1(6) NAME settings allows to user to assign a name to each of the six settings groups. Once pro-
grammed, this name will appear on the second line of the GROUPED ELEMENTS SETTING GROUP 1(6) menu display.
The relay can be set up via a FlexLogic™ equation to receive requests to activate or de-activate a particular non-default
settings group. The following FlexLogic™ equation (see the figure below) illustrates requests via remote communications
(e.g. VIRTUAL INPUT 1) or from a local contact input (e.g. H7a) to initiate the use of a particular settings group, and requests
from several overcurrent pickup measuring elements to inhibit the use of the particular settings group. The assigned VIR-
TUAL OUTPUT 1 operand is used to control the “On” state of a particular settings group.

 5 SETTINGS 5.6 CONTROL ELEMENTS

The Selector Switch element is intended to replace a mechanical selector switch. Typical applications include setting group
control or control of multiple logic sub-circuits in user-programmable logic.
The element provides for two control inputs. The step-up control allows stepping through selector position one step at a
time with each pulse of the control input, such as a user-programmable pushbutton. The 3-bit control input allows setting
the selector to the position defined by a 3-bit word.
The element allows pre-selecting a new position without applying it. The pre-selected position gets applied either after time-
out or upon acknowledgement via separate inputs (user setting). The selector position is stored in non-volatile memory.
Upon power-up, either the previous position is restored or the relay synchronizes to the current 3-bit word (user setting).
Basic alarm functionality alerts the user under abnormal conditions; e.g. the 3-bit control input being out of range.
• SELECTOR 1 FULL RANGE: This setting defines the upper position of the selector. When stepping up through avail-
able positions of the selector, the upper position wraps up to the lower position (Position 1). When using a direct 3-bit
control word for programming the selector to a desired position, the change would take place only if the control word is
within the range of 1 to the SELECTOR FULL RANGE. If the control word is outside the range, an alarm is established by
setting the SELECTOR ALARM FlexLogic™ operand for 3 seconds.
• SELECTOR 1 TIME-OUT: This setting defines the time-out period for the selector. This value is used by the relay in
the following two ways. When the SELECTOR STEP-UP MODE is “Time-out”, the setting specifies the required period of
inactivity of the control input after which the pre-selected position is automatically applied. When the SELECTOR STEP-
UP MODE is “Acknowledge”, the setting specifies the period of time for the acknowledging input to appear. The timer is
re-started by any activity of the control input. The acknowledging input must come before the SELECTOR 1 TIME-OUT
timer expires; otherwise, the change will not take place and an alarm will be set.
• SELECTOR 1 STEP-UP: This setting specifies a control input for the selector switch. The switch is shifted to a new
position at each rising edge of this signal. The position changes incrementally, wrapping up from the last (SELECTOR 1
FULL RANGE) to the first (Position 1). Consecutive pulses of this control operand must not occur faster than every
50 ms. After each rising edge of the assigned operand, the time-out timer is restarted and the SELECTOR SWITCH 1:
POS Z CHNG INITIATED target message is displayed, where Z the pre-selected position. The message is displayed for
5
the time specified by the FLASH MESSAGE TIME setting. The pre-selected position is applied after the selector times out
(“Time-out” mode), or when the acknowledging signal appears before the element times out (“Acknowledge” mode).
When the new position is applied, the relay displays the SELECTOR SWITCH 1: POSITION Z IN USE message. Typically,
a user-programmable pushbutton is configured as the stepping up control input.
• SELECTOR 1 STEP-UP MODE: This setting defines the selector mode of operation. When set to “Time-out”, the
selector will change its position after a pre-defined period of inactivity at the control input. The change is automatic and
does not require any explicit confirmation of the intent to change the selector's position. When set to “Acknowledge”,
the selector will change its position only after the intent is confirmed through a separate acknowledging signal. If the
acknowledging signal does not appear within a pre-defined period of time, the selector does not accept the change
and an alarm is established by setting the SELECTOR STP ALARM output FlexLogic™ operand for 3 seconds.
• SELECTOR 1 ACK: This setting specifies an acknowledging input for the stepping up control input. The pre-selected
position is applied on the rising edge of the assigned operand. This setting is active only under “Acknowledge” mode of
operation. The acknowledging signal must appear within the time defined by the SELECTOR 1 TIME-OUT setting after the
last activity of the control input. A user-programmable pushbutton is typically configured as the acknowledging input.
• SELECTOR 1 3BIT A0, A1, and A2: These settings specify a 3-bit control input of the selector. The 3-bit control word
pre-selects the position using the following encoding convention:

A2 A1 A0 POSITION
0 0 0 rest
0 0 1 1
0 1 0 2
0 1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7

GE Multilin F35 Multiple Feeder Management Relay 5-93

 5.6 CONTROL ELEMENTS 5 SETTINGS

The “rest” position (0, 0, 0) does not generate an action and is intended for situations when the device generating the
3-bit control word is having a problem. When SELECTOR 1 3BIT MODE is “Time-out”, the pre-selected position is applied
in SELECTOR 1 TIME-OUT seconds after the last activity of the 3-bit input. When SELECTOR 1 3BIT MODE is “Acknowl-
edge”, the pre-selected position is applied on the rising edge of the SELECTOR 1 3BIT ACK acknowledging input.
The stepping up control input (SELECTOR 1 STEP-UP) and the 3-bit control inputs (SELECTOR 1 3BIT A0 through A2) lock-
out mutually: once the stepping up sequence is initiated, the 3-bit control input is inactive; once the 3-bit control
sequence is initiated, the stepping up input is inactive.
• SELECTOR 1 3BIT MODE: This setting defines the selector mode of operation. When set to “Time-out”, the selector
changes its position after a pre-defined period of inactivity at the control input. The change is automatic and does not
require explicit confirmation to change the selector position. When set to “Acknowledge”, the selector changes its posi-
tion only after confirmation via a separate acknowledging signal. If the acknowledging signal does not appear within a
pre-defined period of time, the selector rejects the change and an alarm established by invoking the SELECTOR BIT
ALARM FlexLogic™ operand for 3 seconds.
• SELECTOR 1 3BIT ACK: This setting specifies an acknowledging input for the 3-bit control input. The pre-selected
position is applied on the rising edge of the assigned FlexLogic™ operand. This setting is active only under the
“Acknowledge” mode of operation. The acknowledging signal must appear within the time defined by the SELECTOR
TIME-OUT setting after the last activity of the 3-bit control inputs. Note that the stepping up control input and 3-bit control
input have independent acknowledging signals (SELECTOR 1 ACK and SELECTOR 1 3BIT ACK, accordingly).
• SELECTOR 1 POWER-UP MODE: This setting specifies the element behavior on power up of the relay.
When set to “Restore”, the last position of the selector (stored in the non-volatile memory) is restored after powering up
the relay. If the position restored from memory is out of range, position 0 (no output operand selected) is applied and
an alarm is set (SELECTOR 1 PWR ALARM).
When set to “Synchronize” selector switch acts as follows. For two power cycles, the selector applies position 0 to the
5 switch and activates SELECTOR 1 PWR ALARM. After two power cycles expire, the selector synchronizes to the position
dictated by the 3-bit control input. This operation does not wait for time-out or the acknowledging input. When the syn-
chronization attempt is unsuccessful (i.e., the 3-bit input is not available (0,0,0) or out of range) then the selector switch
output is set to position 0 (no output operand selected) and an alarm is established (SELECTOR 1 PWR ALARM).
The operation of “Synch/Restore” mode is similar to the “Synchronize” mode. The only difference is that after an
unsuccessful synchronization attempt, the switch will attempt to restore the position stored in the relay memory. The
“Synch/Restore” mode is useful for applications where the selector switch is employed to change the setting group in
redundant (two relay) protection schemes.
• SELECTOR 1 EVENTS: If enabled, the following events are logged:

EVENT NAME DESCRIPTION

SELECTOR 1 POS Z Selector 1 changed its position to Z.
SELECTOR 1 STP ALARM The selector position pre-selected via the stepping up control input has not been
confirmed before the time out.

APPLICATION EXAMPLE
Consider an application where the selector switch is used to control Setting Groups 1 through 4 in the relay. The setting
groups are to be controlled from both User-Programmable Pushbutton 1 and from an external device via Contact Inputs 1
through 3. The active setting group shall be available as an encoded 3-bit word to the external device and SCADA via out-
put contacts 1 through 3. The pre-selected setting group shall be applied automatically after 5 seconds of inactivity of the
control inputs. When the relay powers up, it should synchronize the setting group to the 3-bit control input.
Make the following changes to Setting Group Control in the SETTINGS CONTROL ELEMENTS SETTING GROUPS menu:

There are six identical underfrequency elements, numbered from 1 through 6 inclusive.
The steady-state frequency of a power system is a certain indicator of the existing balance between the generated power
and the load. Whenever this balance is disrupted through the loss of an important generating unit or the isolation of part of
the system from the rest of the system, the effect will be a reduction in frequency. If the control systems of the system gen-
erators do not respond fast enough, the system may collapse. A reliable method to quickly restore the balance between
load and generation is to automatically disconnect selected loads, based on the actual system frequency. This technique,
called "load-shedding", maintains system integrity and minimize widespread outages. After the frequency returns to normal,
the load may be automatically or manually restored.
The UNDERFREQ 1 SOURCE setting is used to select the source for the signal to be measured. The element first checks for a
live phase voltage available from the selected Source. If voltage is not available, the element attempts to use a phase cur-
rent. If neither voltage nor current is available, the element will not operate, as it will not measure a parameter above the
minimum voltage/current setting.
The UNDERFREQ 1 MIN VOLT/AMP setting selects the minimum per unit voltage or current level required to allow the underfre-
quency element to operate. This threshold is used to prevent an incorrect operation because there is no signal to measure.
This UNDERFREQ 1 PICKUP setting is used to select the level at which the underfrequency element is to pickup. For example,
if the system frequency is 60 Hz and the load shedding is required at 59.5 Hz, the setting will be 59.50 Hz.

The maximum number of autoreclosure elements available is equal to the number of installed CT banks.
The autoreclosure feature is intended for use with transmission and distribution lines, in three-pole tripping schemes for sin-
gle breaker applications. Up to four selectable reclosures ‘shots’ are possible prior to locking out. Each shot has an inde-
pendently settable dead time. The protection settings can be changed between shots if so desired, using FlexLogic™.
Logic inputs are available for disabling or blocking the scheme.
Faceplate panel LEDs indicate the state of the autoreclose scheme as follows:
• Reclose Enabled: The scheme is enabled and may reclose if initiated.
• Reclose Disabled: The scheme is disabled.
• Reclose In Progress: An autoreclosure has been initiated but the breaker has not yet been signaled to close.

5 • Reclose Locked Out: The scheme has generated the maximum number of breaker closures allowed and, as the fault
persists, will not close the breaker again; known as ‘Lockout’. The scheme may also be sent in ‘Lockout’ when the
incomplete sequence timer times out or when a block signal occurs while in ‘reclose in progress’. The scheme must be
reset from Lockout in order to perform reclose for further faults.
The reclosure scheme is considered enabled when all of the following conditions are true:
• The AR1(6) FUNCTION is set to “Enabled”.
• The scheme is not in the ‘Lockout’ state.
• The ‘Block’ input is not asserted.
• The AR1(6) BLK TIME UPON MNL CLS timer is not active.
The autoreclose scheme is initiated by a trip signal from any selected protection feature operand. The scheme is initiated
provided the circuit breaker is in the closed state before protection operation.
The reclose-in-progress (RIP) is set when a reclosing cycle begins following a reclose initiate signal. Once the cycle is suc-
cessfully initiated, the RIP signal will seal-in and the scheme will continue through its sequence until one of the following
conditions is satisfied:
• The close signal is issued when the dead timer times out, or
• The scheme goes to lockout.
While RIP is active, the scheme checks that the breaker is open and the shot number is below the limit, and then begins
measuring the dead time.
Each of the four possible shots has an independently settable dead time. Two additional timers can be used to increase the
initial set dead times 1 to 4 by a delay equal to AR1(6) DELAY 1 or AR1(6) DELAY 2 or the sum of these two delays depending
on the selected settings. This offers enhanced setting flexibility using FlexLogic™ operands to turn the two additional timers
“on” and “off”. These operands may possibly include AR1 SHOT CNT =n, SETTING GROUP ACT 1, etc. The autoreclose pro-
vides up to maximum 4 selectable shots. Maximum number of shots can be dynamically modified through the settings
AR1(6) REDUCE MAX TO 1 (2, 3), using the appropriate FlexLogic™ operand.

Scheme lockout blocks all phases of the reclosing cycle, preventing automatic reclosure, if any of the following occurs:
• The maximum shot number was reached.
• A ‘Block’ input is in effect (for instance; Breaker Failure, bus differential protection operated, etc.).

5-100 F35 Multiple Feeder Management Relay GE Multilin

 5 SETTINGS 5.6 CONTROL ELEMENTS

• The ‘Incomplete Sequence’ timer times out.

The recloser will be latched in the Lockout state until a ‘reset from lockout’ signal is asserted, either from a manual close of
the breaker or from a manual reset command (local or remote). The reset from lockout can be accomplished by operator
command, by manually closing the breaker, or whenever the breaker has been closed and stays closed for a preset time.
After the dead time elapses, the scheme issues the close signal. The close signal is latched until the breaker closes or the
scheme goes to Lockout.
A reset timer output resets the recloser following a successful reclosure sequence. The reset time is based on the breaker
‘reclaim time’ which is the minimum time required between successive reclose sequences.
SETTINGS:
• AR1(6) INITIATE: Selects the FlexLogic™ operand that initiates the scheme, typically the trip signal from protection.
• AR1(6) BLOCK: Selects the FlexLogic™ operand that blocks the autoreclosure initiate (it could be from the breaker
failure, bus differential protection, etc.).
• AR1(6) MAX NUMBER OF SHOTS: Specifies the number of reclosures that can be attempted before reclosure goes
to “Lockout” because the fault is permanent.
• AR1(6) REDUCE MAX TO 1(3): Selects the FlexLogic™ operand that changes the maximum number of shots from
the initial setting to 1, 2, or 3, respectively.
• AR1(6) MANUAL CLOSE: Selects the logic input set when the breaker is manually closed.
• AR1(6) MNL RST FRM LO: Selects the FlexLogic™ operand that resets the autoreclosure from Lockout condition.
Typically this is a manual reset from lockout, local or remote.
• AR1(6) RESET LOCKOUT IF BREAKER CLOSED: This setting allows the autoreclose scheme to reset from Lockout
if the breaker has been manually closed and stays closed for a preset time. In order for this setting to be effective, the
next setting (AR1(6) RESET LOCKOUT ON MANUAL CLOSE) should be disabled. 5
• AR1(6) RESET LOCKOUT ON MANUAL CLOSE: This setting allows the autoreclose scheme to reset from Lockout
when the breaker is manually closed regardless if the breaker remains closed or not. This setting overrides the previ-
ous setting (AR1 RESET LOCKOUT IF BREAKER CLOSED).
• AR1(6) BLK TIME UPON MNL CLS: The autoreclose scheme can be disabled for a programmable time delay after
the associated circuit breaker is manually closed. This prevents reclosing onto a fault after a manual close. This delay
must be longer than the slowest expected trip from any protection not blocked after manual closing. If no overcurrent
trips occur after a manual close and this time expires, the autoreclose scheme is enabled.
• AR1(6) DEAD TIME 1 to AR1(6) DEAD TIME 4: These are the intentional delays before first, second, third, and fourth
breaker automatic reclosures (1st, 2nd, and 3rd shots), respectively, and should be set longer than the estimated
deionizing time following a three pole trip.
• AR1(6) ADD DELAY 1: This setting selects the FlexLogic™ operand that introduces an additional delay (Delay 1) to
the initial set Dead Time (1 to 4). When this setting is “Off”, Delay 1 is by-passed.
• AR1(6) DELAY 1: This setting establishes the extent of the additional dead time Delay 1.
• AR1(6) ADD DELAY 2: This setting selects the FlexLogic™ operand that introduces an additional delay (Delay 2) to
the initial set Dead Time (1 to 4). When this setting is “Off”, Delay 2 is by-passed.
• AR1(6) DELAY 2: This setting establishes the extent of the additional dead time Delay 2.
• AR1(6) RESET LOCKOUT DELAY: This setting establishes how long the breaker should stay closed after a manual
close command, in order for the autorecloser to reset from Lockout.
• AR1(6) RESET TIME: A reset timer output resets the recloser following a successful reclosure sequence. The setting
is based on the breaker ‘reclaim time’ which is the minimum time required between successive reclose sequences.
• AR1(6) INCOMPLETE SEQ TIME: This timer defines the maximum time interval allowed for a single reclose shot. It is
started whenever a reclosure is initiated and is active when the scheme is in the ‘reclose-in-progress’ state. If all condi-
tions allowing a breaker closure are not satisfied when this time expires, the scheme goes to “Lockout”.
This timer must be set to a delay less than the reset timer.

CIRCUIT MONITORING APPLICATIONS:
Some versions of the digital input modules include an active voltage monitor circuit connected across Form-A contacts. The
voltage monitor circuit limits the trickle current through the output circuit (see technical specifications for Form-A).

GE Multilin F35 Multiple Feeder Management Relay 5-105

 5.6 CONTROL ELEMENTS 5 SETTINGS

As long as the current through the Voltage Monitor is above a threshold (see technical specifications for Form-A), the Flex-
Logic™ operand "Cont Op # VOn" will be set (# represents the output contact number). If the output circuit has a high resis-
tance or the DC current is interrupted, the trickle current will drop below the threshold and the FlexLogic™ operand "Cont
Op # VOff" will be set. Consequently, the state of these operands can be used as indicators of the integrity of the circuits in
which Form-A contacts are inserted.
EXAMPLE 1: BREAKER TRIP CIRCUIT INTEGRITY MONITORING
In many applications it is desired to monitor the breaker trip circuit integrity so problems can be detected before a trip oper-
ation is required. The circuit is considered to be healthy when the voltage monitor connected across the trip output contact
detects a low level of current, well below the operating current of the breaker trip coil. If the circuit presents a high resis-
tance, the trickle current will fall below the monitor threshold and an alarm would be declared.
In most breaker control circuits, the trip coil is connected in series with a breaker auxiliary contact which is open when the
breaker is open (see diagram below). To prevent unwanted alarms in this situation, the trip circuit monitoring logic must
include the breaker position.

EXAMPLE 2: BREAKER TRIP CIRCUIT INTEGRITY MONITORING

If it is required to monitor the trip circuit continuously, independent of the breaker position (open or closed), a method to
maintain the monitoring current flow through the trip circuit when the breaker is open must be provided (as shown in the fig-
ure below). This can be achieved by connecting a suitable resistor (see figure below) across the auxiliary contact in the trip
circuit. In this case, it is not required to supervise the monitoring circuit with the breaker position – the BLOCK setting is

There are 8 identical digital counters, numbered from 1 to 8. A digital counter counts the number of state transitions from
Logic 0 to Logic 1. The counter is used to count operations such as the pickups of an element, the changes of state of an
external contact (e.g. breaker auxiliary switch), or pulses from a watt-hour meter.
• COUNTER 1 UNITS: Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted.
The units label will appear in the corresponding actual values status.
• COUNTER 1 PRESET: Sets the count to a required preset value before counting operations begin, as in the case
where a substitute relay is to be installed in place of an in-service relay, or while the counter is running.
• COUNTER 1 COMPARE: Sets the value to which the accumulated count value is compared. Three FlexLogic™ output
operands are provided to indicate if the present value is ‘more than (HI)’, ‘equal to (EQL)’, or ‘less than (LO)’ the set
value.
• COUNTER 1 UP: Selects the FlexLogic™ operand for incrementing the counter. If an enabled UP input is received
when the accumulated value is at the limit of +2,147,483,647 counts, the counter will rollover to –2,147,483,648.
• COUNTER 1 DOWN: Selects the FlexLogic™ operand for decrementing the counter. If an enabled DOWN input is
received when the accumulated value is at the limit of –2,147,483,648 counts, the counter will rollover to
+2,147,483,647.
• COUNTER 1 BLOCK: Selects the FlexLogic™ operand for blocking the counting operation. All counter operands are
blocked.

 5 SETTINGS 5.6 CONTROL ELEMENTS

• CNT1 SET TO PRESET: Selects the FlexLogic™ operand used to set the count to the preset value. The counter will
be set to the preset value in the following situations:
1. When the counter is enabled and the CNT1 SET TO PRESET operand has the value 1 (when the counter is enabled
and CNT1 SET TO PRESET operand is 0, the counter will be set to 0).
2. When the counter is running and the CNT1 SET TO PRESET operand changes the state from 0 to 1 (CNT1 SET TO
PRESET changing from 1 to 0 while the counter is running has no effect on the count).
3. When a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the value
1 (when a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the
value 0, the counter will be set to 0).
• COUNTER 1 RESET: Selects the FlexLogic™ operand for setting the count to either “0” or the preset value depending
on the state of the CNT1 SET TO PRESET operand.
• COUNTER 1 FREEZE/RESET: Selects the FlexLogic™ operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and resetting the count to “0”.
• COUNTER 1 FREEZE/COUNT: Selects the FlexLogic™ operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and continuing counting. The present accumulated
value and captured frozen value with the associated date/time stamp are available as actual values. If control power is
interrupted, the accumulated and frozen values are saved into non-volatile memory during the power down operation.

This feature allows switching between two input arguments defined by 8 bits each. The bits are specified by FlexLogic™
operands. The feature could be viewed as an integrated two-position switch for 8 logic signals.
Typically this element is applied in conjunction with the Digitizer and 8-bit Comparator features.
• 8BIT SW 1 ARG A0 to 8BIT SW 1 ARG A7: These settings specify FlexLogic™ operands that constitute the first (A)
input of the switch. These operands are routed to the output operands if the control input is in the "Off" position.
• BIT SW 1 ARG B0 to 8BIT SW 1 ARG B7: These settings specify FlexLogic™ operands that constitute the second (B)
input of the switch. These operands are routed to the output operands if the control input is in the "On" position.
• 8BIT SW 1 CONTROL: This setting specifies FlexLogic™ operands to control the routing between the A and B inputs
of the switch. If the control operand is in the "Off" state, the first (A) input is switched to the output. If the control oper-
and is in the "On" state, the second (B) input is switched to the output. The switching takes place instantaneously.

There is one Breaker Arcing Current element available per CT bank, with a minimum of 2 elements. This element calcu-
lates an estimate of the per-phase wear on the breaker contacts by measuring and integrating the current squared passing
through the breaker contacts as an arc. These per-phase values are added to accumulated totals for each phase and com-
pared to a programmed threshold value. When the threshold is exceeded in any phase, the relay can set an output operand
to “1”. The accumulated value for each phase can be displayed as an actual value.
The operation of the scheme is shown in the following logic diagram. The same output operand that is selected to operate
the output relay used to trip the breaker, indicating a tripping sequence has begun, is used to initiate this feature. A time
delay is introduced between initiation and the starting of integration to prevent integration of current flow through the
breaker before the contacts have parted. This interval includes the operating time of the output relay, any other auxiliary
relays and the breaker mechanism. For maximum measurement accuracy, the interval between change-of-state of the
operand (from 0 to 1) and contact separation should be measured for the specific installation. Integration of the measured
current continues for 100 ms, which is expected to include the total arcing period.
The feature is programmed to perform fault duration calculations. Fault duration is defined as a time between operation of
the disturbance detector occurring before initiation of this feature, and reset of an internal low-set overcurrent function. Cor-
rection is implemented to account for a non-zero reset time of the overcurrent function.
Breaker arcing currents and fault duration values are available under the ACTUAL VALUES RECORDS MAINTENANCE
BREAKER 1(6) menus.

• BKR 1(6) ARC AMP INT-A(C): Select the same output operands that are configured to operate the output relays used
to trip the breaker. In three-pole tripping applications, the same operand should be configured to initiate arcing current
calculations for poles A, B and C of the breaker. In single-pole tripping applications, per-pole tripping operands should
be configured to initiate the calculations for the poles that are actually tripped.
• BKR 1(6) ARC AMP DELAY: This setting is used to program the delay interval between the time the tripping sequence
is initiated and the time the breaker contacts are expected to part, starting the integration of the measured current.
• BKR 1(6) ARC AMP LIMIT: Selects the threshold value above which the output operand is set.

The contact inputs menu contains configuration settings for each contact input as well as voltage thresholds for each group
of four contact inputs. Upon startup, the relay processor determines (from an assessment of the installed modules) which
contact inputs are available and then display settings for only those inputs.
An alphanumeric ID may be assigned to a contact input for diagnostic, setting, and event recording purposes. The CON-
TACT IP X On” (Logic 1) FlexLogic™ operand corresponds to contact input “X” being closed, while CONTACT IP X Off corre-
sponds to contact input “X” being open. The CONTACT INPUT DEBNCE TIME defines the time required for the contact to
overcome ‘contact bouncing’ conditions. As this time differs for different contact types and manufacturers, set it as a maxi-
mum contact debounce time (per manufacturer specifications) plus some margin to ensure proper operation. If CONTACT
INPUT EVENTS is set to “Enabled”, every change in the contact input state will trigger an event.

A raw status is scanned for all Contact Inputs synchronously at the constant rate of 0.5 ms as shown in the figure below.
The DC input voltage is compared to a user-settable threshold. A new contact input state must be maintained for a user-
settable debounce time in order for the F35 to validate the new contact state. In the figure below, the debounce time is set
at 2.5 ms; thus the 6th sample in a row validates the change of state (mark no. 1 in the diagram). Once validated (de-
bounced), the contact input asserts a corresponding FlexLogic™ operand and logs an event as per user setting.
A time stamp of the first sample in the sequence that validates the new state is used when logging the change of the con-
tact input into the Event Recorder (mark no. 2 in the diagram).
Protection and control elements, as well as FlexLogic™ equations and timers, are executed eight times in a power system
cycle. The protection pass duration is controlled by the frequency tracking mechanism. The FlexLogic™ operand reflecting
the debounced state of the contact is updated at the protection pass following the validation (marks no. 3 and 4 on the fig-
ure below). The update is performed at the beginning of the protection pass so all protection and control functions, as well
as FlexLogic™ equations, are fed with the updated states of the contact inputs.

5-114 F35 Multiple Feeder Management Relay GE Multilin

 5 SETTINGS 5.7 INPUTS/OUTPUTS

The FlexLogic™ operand response time to the contact input change is equal to the debounce time setting plus up to one
protection pass (variable and depending on system frequency if frequency tracking enabled). If the change of state occurs
just after a protection pass, the recognition is delayed until the subsequent protection pass; that is, by the entire duration of
the protection pass. If the change occurs just prior to a protection pass, the state is recognized immediately. Statistically a
delay of half the protection pass is expected. Owing to the 0.5 ms scan rate, the time resolution for the input contact is
below 1msec.
For example, 8 protection passes per cycle on a 60 Hz system correspond to a protection pass every 2.1 ms. With a con-
tact debounce time setting of 3.0 ms, the FlexLogic™ operand-assert time limits are: 3.0 + 0.0 = 3.0 ms and 3.0 + 2.1 = 5.1
ms. These time limits depend on how soon the protection pass runs after the debouncing time.
Regardless of the contact debounce time setting, the contact input event is time-stamped with a 1 μs accuracy using the
time of the first scan corresponding to the new state (mark no. 2 below). Therefore, the time stamp reflects a change in the
DC voltage across the contact input terminals that was not accidental as it was subsequently validated using the debounce
timer. Keep in mind that the associated FlexLogic™ operand is asserted/de-asserted later, after validating the change.
The debounce algorithm is symmetrical: the same procedure and debounce time are used to filter the LOW-HIGH (marks
no.1, 2, 3, and 4 in the figure below) and HIGH-LOW (marks no. 5, 6, 7, and 8 below) transitions.

Contact inputs are isolated in groups of four to allow connection of wet contacts from different voltage sources for each
group. The CONTACT INPUT THRESHOLDS determine the minimum voltage required to detect a closed contact input. This
value should be selected according to the following criteria: 17 for 24 V sources, 33 for 48 V sources, 84 for 110 to 125 V
sources and 166 for 250 V sources.
For example, to use contact input H5a as a status input from the breaker 52b contact to seal-in the trip relay and record it in
the Event Records menu, make the following settings changes:
CONTACT INPUT H5A ID: "Breaker Closed (52b)"
CONTACT INPUT H5A EVENTS: "Enabled"

Note that the 52b contact is closed when the breaker is open and open when the breaker is closed.

There are 64 virtual inputs that can be individually programmed to respond to input signals from the keypad (Commands
menu) and communications protocols. All virtual input operands are defaulted to OFF = 0 unless the appropriate input sig-
nal is received. Virtual input states are preserved through a control power loss.
If the VIRTUAL INPUT x FUNCTION is to “Disabled”, the input will be forced to 'Off' (Logic 0) regardless of any attempt to alter
the input. If set to “Enabled”, the input operates as shown on the logic diagram and generates output FlexLogic™ operands
in response to received input signals and the applied settings.
There are two types of operation: Self-Reset and Latched. If VIRTUAL INPUT x TYPE is “Self-Reset”, when the input signal
transits from OFF = 0 to ON = 1, the output operand will be set to ON = 1 for only one evaluation of the FlexLogic™ equa-
tions and then return to OFF = 0. If set to “Latched”, the virtual input sets the state of the output operand to the same state
as the most recent received input, ON =1 or OFF = 0.
5 The “Self-Reset” operating mode generates the output operand for a single evaluation of the FlexLogic™
equations. If the operand is to be used anywhere other than internally in a FlexLogic™ equation, it will

Upon startup of the relay, the main processor will determine from an assessment of the modules installed in the chassis
which contact outputs are available and present the settings for only these outputs.
An ID may be assigned to each contact output. The signal that can OPERATE a contact output may be any FlexLogic™
operand (virtual output, element state, contact input, or virtual input). An additional FlexLogic™ operand may be used to
SEAL-IN the relay. Any change of state of a contact output can be logged as an Event if programmed to do so.

For example, the trip circuit current is monitored by providing a current threshold detector in series with some Form-A con-
tacts (see the trip circuit example in the Digital Elements section). The monitor will set a flag (see the specifications for
Form-A). The name of the FlexLogic™ operand set by the monitor, consists of the output relay designation, followed by the
name of the flag; e.g. ‘Cont Op 1 IOn’ or ‘Cont Op 1 IOff’.
In most breaker control circuits, the trip coil is connected in series with a breaker auxiliary contact used to interrupt current 5
flow after the breaker has tripped, to prevent damage to the less robust initiating contact. This can be done by monitoring
an auxiliary contact on the breaker which opens when the breaker has tripped, but this scheme is subject to incorrect oper-
ation caused by differences in timing between breaker auxiliary contact change-of-state and interruption of current in the
trip circuit. The most dependable protection of the initiating contact is provided by directly measuring current in the tripping
circuit, and using this parameter to control resetting of the initiating relay. This scheme is often called ‘trip seal-in’.
This can be realized in the F35 using the ‘Cont Op 1 IOn’ FlexLogic™ operand to seal-in the contact output as follows:
CONTACT OUTPUT H1 ID: “Cont Op 1"

The F35 latching output contacts are mechanically bi-stable and controlled by two separate (open and close) coils. As such
they retain their position even if the relay is not powered up. The relay recognizes all latching output contact cards and pop-
ulates the setting menu accordingly. On power up, the relay reads positions of the latching contacts from the hardware
before executing any other functions of the relay (such as protection and control features or FlexLogic™).
The latching output modules, either as a part of the relay or as individual modules, are shipped from the factory with all
latching contacts opened. It is highly recommended to double-check the programming and positions of the latching con-
tacts when replacing a module.
Since the relay asserts the output contact and reads back its position, it is possible to incorporate self-monitoring capabili-
ties for the latching outputs. If any latching outputs exhibits a discrepancy, the LATCHING OUTPUT ERROR self-test error is
declared. The error is signaled by the LATCHING OUT ERROR FlexLogic™ operand, event, and target message.
• OUTPUT H1a OPERATE: This setting specifies a FlexLogic™ operand to operate the ‘close coil’ of the contact. The
relay will seal-in this input to safely close the contact. Once the contact is closed and the RESET input is logic 0 (off),
any activity of the OPERATE input, such as subsequent chattering, will not have any effect. With both the OPERATE and
RESET inputs active (logic 1), the response of the latching contact is specified by the OUTPUT H1A TYPE setting.

• OUTPUT H1a RESET: This setting specifies a FlexLogic™ operand to operate the ‘trip coil’ of the contact. The relay
will seal-in this input to safely open the contact. Once the contact is opened and the OPERATE input is logic 0 (off), any
activity of the RESET input, such as subsequent chattering, will not have any effect. With both the OPERATE and RESET
inputs active (logic 1), the response of the latching contact is specified by the OUTPUT H1A TYPE setting.
• OUTPUT H1a TYPE: This setting specifies the contact response under conflicting control inputs; that is, when both the
OPERATE and RESET signals are applied. With both control inputs applied simultaneously, the contact will close if set to
“Operate-dominant” and will open if set to “Reset-dominant”.

Application Example 1:

5 A latching output contact H1a is to be controlled from two user-programmable pushbuttons (buttons number 1 and 2). The
following settings should be applied.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a menu (assuming an H4L module):

OUTPUT H1a OPERATE: “PUSHBUTTON 1 ON”

OUTPUT H1a RESET: “PUSHBUTTON 2 ON”

Program the pushbuttons by making the following changes in the PRODUCT SETUP USER-PROGRAMMABLE PUSHBUT-
TONS USER PUSHBUTTON 1 and USER PUSHBUTTON 2 menus:

PUSHBUTTON 1 FUNCTION: “Self-reset” PUSHBUTTON 2 FUNCTION: “Self-reset”

PUSHBTN 1 DROP-OUT TIME: “0.00 s” PUSHBTN 2 DROP-OUT TIME: “0.00 s”

Application Example 2:
A relay, having two latching contacts H1a and H1c, is to be programmed. The H1a contact is to be a Type-a contact, while
the H1c contact is to be a Type-b contact (Type-a means closed after exercising the operate input; Type-b means closed
after exercising the reset input). The relay is to be controlled from virtual outputs: VO1 to operate and VO2 to reset.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a and CONTACT OUTPUT H1c menus (assuming an H4L module):

OUTPUT H1a OPERATE: “VO1” OUTPUT H1c OPERATE: “VO2”

OUTPUT H1a RESET: “VO2” OUTPUT H1c RESET: “VO1”

Since the two physical contacts in this example are mechanically separated and have individual control inputs, they will not
operate at exactly the same time. A discrepancy in the range of a fraction of a maximum operating time may occur. There-
fore, a pair of contacts programmed to be a multi-contact relay will not guarantee any specific sequence of operation (such
as make before break). If required, the sequence of operation must be programmed explicitly by delaying some of the con-
trol inputs as shown in the next application example.

Application Example 3:
A make before break functionality must be added to the preceding example. An overlap of 20 ms is required to implement
this functionality as described below:

5.7.5 REMOTE DEVICES

a) REMOTE INPUTS/OUTPUTS OVERVIEW

Remote inputs and outputs provide a means of exchanging digital state information between Ethernet-networked devices.
The IEC 61850 GSSE (Generic Substation State Event) and GOOSE (Generic Object Oriented Substation Event) stan-
dards are used.
The IEC 61850 specification requires that communications between devices be implemented on Ethernet.
For UR-series relays, Ethernet communications is provided only all CPU modules except type 9E.
NOTE

The sharing of digital point state information between GSSE/GOOSE equipped relays is essentially an extension to Flex-
Logic™, allowing distributed FlexLogic™ by making operands available to/from devices on a common communications net-
work. In addition to digital point states, GSSE/GOOSE messages identify the originator of the message and provide other
information required by the communication specification. All devices listen to network messages and capture data only from
messages that have originated in selected devices.
IEC 61850 GSSE messages are compatible with UCA GOOSE messages and contain a fixed set of digital points. IEC
61850 GOOSE messages can, in general, contain any configurable data items. When used by the remote input/output fea-
ture, IEC 61850 GOOSE messages contain the same data as GSSE messages.
Both GSSE and GOOSE messages are designed to be short, reliable, and high priority. GOOSE messages have additional
advantages over GSSE messages due to their support of VLAN (virtual LAN) and Ethernet priority tagging functionality.
The GSSE message structure contains space for 128 bit pairs representing digital point state information. The IEC 61850
specification provides 32 “DNA” bit pairs that represent the state of two pre-defined events and 30 user-defined events. All
remaining bit pairs are “UserSt” bit pairs, which are status bits representing user-definable events. The F35 implementation
provides 32 of the 96 available UserSt bit pairs.

5 The IEC 61850 specification includes features that are used to cope with the loss of communication between transmitting
and receiving devices. Each transmitting device will send a GSSE/GOOSE message upon a successful power-up, when
the state of any included point changes, or after a specified interval (the default update time) if a change-of-state has not
occurred. The transmitting device also sends a ‘hold time’ which is set greater than three times the programmed default
time required by the receiving device.
Receiving devices are constantly monitoring the communications network for messages they require, as recognized by the
identification of the originating device carried in the message. Messages received from remote devices include the mes-
sage time allowed to live. The receiving relay sets a timer assigned to the originating device to this time interval, and if it
has not received another message from this device at time-out, the remote device is declared to be non-communicating, so
it will use the programmed default state for all points from that specific remote device. If a message is received from a
remote device before the time allowed to live expires, all points for that device are updated to the states contained in the
message and the hold timer is restarted. The status of a remote device, where “Offline” indicates non-communicating, can
be displayed.
The remote input/output facility provides for 32 remote inputs and 64 remote outputs.

b) LOCAL DEVICES: ID OF DEVICE FOR TRANSMITTING GSSE MESSAGES

Sixteen remote devices, numbered from 1 to 16, can be selected for setting purposes. A receiving relay must be pro-
grammed to capture messages from only those originating remote devices of interest. This setting is used to select specific
remote devices by entering (bottom row) the exact identification (ID) assigned to those devices.
The REMOTE DEVICE 1(16) VLAN ID and REMOTE DEVICE 1(16) ETYPE APPID settings are only used with GOOSE messages;
they are not applicable to GSSE messages. The REMOTE DEVICE 1(16) VLAN ID setting identifies the virtual LAN on which the
remote device is sending the GOOSE message. The REMOTE DEVICE 1(16) ETYPE APPID setting identifies the Ethernet appli-
cation identification in the GOOSE message. These settings should match the corresponding settings on the sending
device.

Remote Inputs which create FlexLogic™ operands at the receiving relay, are extracted from GSSE/GOOSE messages
originating in remote devices. The relay provides 32 remote inputs, each of which can be selected from a list consisting of
64 selections: DNA-1 through DNA-32 and UserSt-1 through UserSt-32. The function of DNA inputs is defined in the IEC
61850 specification and is presented in the IEC 61850 DNA Assignments table in the Remote Outputs section. The function
of UserSt inputs is defined by the user selection of the FlexLogic™ operand whose state is represented in the GSSE/
GOOSE message. A user must program a DNA point from the appropriate FlexLogic™ operand.
Remote Input 1 must be programmed to replicate the logic state of a specific signal from a specific remote device for local
use. This programming is performed via the three settings shown above.
The REMOTE INPUT 1 ID setting allows the user to assign descriptive text to the remote input. The REMOTE IN 1 DEVICE setting
selects the number (1 to 16) of the remote device which originates the required signal, as previously assigned to the remote
device via the setting REMOTE DEVICE NN ID (see the Remote Devices section). REMOTE IN 1 BIT PAIR selects the specific bits
of the GSSE/GOOSE message required.
The REMOTE IN 1 DEFAULT STATE setting selects the logic state for this point if the local relay has just completed startup or
the remote device sending the point is declared to be non-communicating. The following choices are available:
• Setting REMOTE IN 1 DEFAULT STATE to “On” value defaults the input to Logic 1.
• Setting REMOTE IN 1 DEFAULT STATE to “Off” value defaults the input to Logic 0.
• Setting REMOTE IN 1 DEFAULT STATE to “Latest/On” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to Logic 1.
When communication resumes, the input becomes fully operational.
• Setting REMOTE IN 1 DEFAULT STATE to “Latest/Off” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to Logic 0.
When communication resumes, the input becomes fully operational.

Some events can be programmed to latch the faceplate LED event indicators and the target message on the display. Once
set, the latching mechanism will hold all of the latched indicators or messages in the set state after the initiating condition
has cleared until a RESET command is received to return these latches (not including FlexLogic™ latches) to the reset
state. The RESET command can be sent from the faceplate Reset button, a remote device via a communications channel,
or any programmed operand.
When the RESET command is received by the relay, two FlexLogic™ operands are created. These operands, which are
stored as events, reset the latches if the initiating condition has cleared. The three sources of RESET commands each cre-
ate the RESET OP FlexLogic™ operand. Each individual source of a RESET command also creates its individual operand
RESET OP (PUSHBUTTON), RESET OP (COMMS) or RESET OP (OPERAND) to identify the source of the command. The setting
shown above selects the operand that will create the RESET OP (OPERAND) operand.

The examples introduced in the earlier Direct Inputs/Outputs section (part of the Product Setup section) direct inputs/out-
puts are continued below to illustrate usage of the direct inputs and outputs.
EXAMPLE 1: EXTENDING INPUT/OUTPUT CAPABILITIES OF A F35 RELAY
Consider an application that requires additional quantities of digital inputs and/or output contacts and/or lines of program-
mable logic that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series
IED, such as the C30, to satisfy the additional inputs/outputs and programmable logic requirements. The two IEDs are con-
nected via single-channel digital communication cards as shown below.

Figure 5–66: INPUT/OUTPUT EXTENSION VIA DIRECT INPUTS/OUTPUTS

Assume Contact Input 1 from UR IED 2 is to be used by UR IED 1. The following settings should be applied (Direct Input 5
and bit number 12 are used, as an example):
UR IED 1: DIRECT INPUT 5 DEVICE ID = “2” UR IED 2: DIRECT OUT 12 OPERAND = “Cont Ip 1 On”
DIRECT INPUT 5 BIT NUMBER = “12”

The Cont Ip 1 On operand of UR IED 2 is now available in UR IED 1 as DIRECT INPUT 5 ON.
EXAMPLE 2: INTERLOCKING BUSBAR PROTECTION
A simple interlocking busbar protection scheme can be accomplished by sending a blocking signal from downstream
devices, say 2, 3 and 4, to the upstream device that monitors a single incomer of the busbar, as shown in the figure below.

Assume that Phase Instantaneous Overcurrent 1 is used by Devices 2, 3, and 4 to block Device 1. If not blocked, Device 1
would trip the bus upon detecting a fault and applying a short coordination time delay.
The following settings should be applied (assume Bit 3 is used by all 3 devices to sent the blocking signal and Direct Inputs
7, 8, and 9 are used by the receiving device to monitor the three blocking signals):
UR IED 2: DIRECT OUT 3 OPERAND: "PHASE IOC1 OP"

UR IED 3: DIRECT OUT 3 OPERAND: "PHASE IOC1 OP"

UR IED 4: DIRECT OUT 3 OPERAND: "PHASE IOC1 OP"

UR IED 1: DIRECT INPUT 7 DEVICE ID: "2"

DIRECT INPUT 7 BIT NUMBER: "3"

DIRECT INPUT 9 DEVICE ID: "4"

DIRECT INPUT 9 DEFAULT STATE: select "On" for security, select "Off" for dependability
Now the three blocking signals are available in UR IED 1 as DIRECT INPUT 7 ON, DIRECT INPUT 8 ON, and DIRECT INPUT 9
ON. Upon losing communications or a device, the scheme is inclined to block (if any default state is set to “On”), or to trip
the bus on any overcurrent condition (all default states set to “Off”).

Hardware and software is provided to receive signals from external transducers and convert these signals into a digital for-
mat for use as required. The relay will accept inputs in the range of –1 to +20 mA DC, suitable for use with most common
transducer output ranges; all inputs are assumed to be linear over the complete range. Specific hardware details are con-
tained in Chapter 3.
Before the dcmA input signal can be used, the value of the signal measured by the relay must be converted to the range
and quantity of the external transducer primary input parameter, such as DC voltage or temperature. The relay simplifies
this process by internally scaling the output from the external transducer and displaying the actual primary parameter.
5
dcmA input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels
with the settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay will automatically generate configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclu-
sive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are automatically generated for every channel available in the specific relay as shown above for the first channel of
a type 5F transducer module installed in slot H.
The function of the channel may be either “Enabled” or “Disabled”. If “Disabled”, no actual values are created for the chan-
nel. An alphanumeric “ID” is assigned to each channel; this ID will be included in the channel actual value, along with the
programmed units associated with the parameter measured by the transducer, such as volts, °C, megawatts, etc. This ID is
also used to reference the channel as the input parameter to features designed to measure this type of parameter. The
DCMA INPUT H1 RANGE setting specifies the mA DC range of the transducer connected to the input channel.

The DCMA INPUT H1 MIN VALUE and DCMA INPUT H1 MAX VALUE settings are used to program the span of the transducer in
primary units. For example, a temperature transducer might have a span from 0 to 250°C; in this case the DCMA INPUT H1
MIN VALUE value is “0” and the DCMA INPUT H1 MAX VALUE value is “250”. Another example would be a watts transducer with
a span from –20 to +180 MW; in this case the DCMA INPUT H1 MIN VALUE value would be “–20” and the DCMA INPUT H1 MAX
VALUE value “180”. Intermediate values between the min and max values are scaled linearly.

The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,

a type 5C transducer module installed in slot H.
The function of the channel may be either “Enabled” or “Disabled”. If “Disabled”, there will not be an actual value created for
5 the channel. An alphanumeric ID is assigned to the channel; this ID will be included in the channel actual values. It is also
used to reference the channel as the input parameter to features designed to measure this type of parameter. Selecting the
type of RTD connected to the channel configures the channel.
Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements™ feature.
In FlexElements™, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by setting
the operate level at 1.5 pu. FlexElement™ operands are available to FlexLogic™ for further interlocking or to operate an

• DCMA OUTPUT H1 RANGE: This setting allows selection of the output range. Each dcmA channel may be set inde-
pendently to work with different ranges. The three most commonly used output ranges are available.
• DCMA OUTPUT H1 MIN VAL: This setting allows setting the minimum limit for the signal that drives the output. This
setting is used to control the mapping between an internal analog value and the output current (see the following
examples). The setting is entered in per-unit values. The base units are defined in the same manner as the FlexEle-
ment™ base units.
• DCMA OUTPUT H1 MAX VAL: This setting allows setting the maximum limit for the signal that drives the output. This
setting is used to control the mapping between an internal analog value and the output current (see the following

 5.8 TRANSDUCER I/O 5 SETTINGS

EXAMPLE 1:
A three phase active power on a 13.8 kV system measured via UR-series relay source 1 is to be monitored by the dcmA H1
output of the range of –1 to 1 mA. The following settings are applied on the relay: CT ratio = 1200:5, VT secondary 115, VT
connection is delta, and VT ratio = 120. The nominal current is 800 A primary and the nominal power factor is 0.90. The
power is to be monitored in both importing and exporting directions and allow for 20% overload compared to the nominal.
The nominal three-phase power is:

P = 3 × 13.8 kV × 0.8 kA × 0.9 = 17.21 MW (EQ 5.19)

The three-phase power with 20% overload margin is:

P max = 1.2 × 17.21 MW = 20.65 MW (EQ 5.20)

The base unit for power (refer to the FlexElements section in this chapter for additional details) is:
P BASE = 115 V × 120 × 1.2 kA = 16.56 MW (EQ 5.21)

The minimum and maximum power values to be monitored (in pu) are:
20.65 MW = – 1.247 pu, maximum power = 20.65 MW- = 1.247 pu
minimum power = –------------------------------ -------------------------- (EQ 5.22)
16.56 MW 16.56 MW
The following settings should be entered:
DCMA OUTPUT H1 SOURCE: “SRC 1 P”
DCMA OUTPUT H1 RANGE: “–1 to 1 mA”
DCMA OUTPUT H1 MIN VAL: “–1.247 pu”
DCMA OUTPUT H1 MAX VAL: “1.247 pu”
5 With the above settings, the output will represent the power with the scale of 1 mA per 20.65 MW. The worst-case error for
this application can be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or ± 0.005 × ( 1 – ( – 1 ) ) × 20.65 MW = ± 0.207 MW
• ±1% of reading error for the active power at power factor of 0.9
For example at the reading of 20 MW, the worst-case error is 0.01 × 20 MW + 0.207 MW = 0.407 MW.
EXAMPLE 2:
The phase A current (true RMS value) is to be monitored via the H2 current output working with the range from 4 to 20 mA.
The CT ratio is 5000:5 and the maximum load current is 4200 A. The current should be monitored from 0 A upwards, allow-
ing for 50% overload.
The phase current with the 50% overload margin is:
I max = 1.5 × 4.2 kA = 6.3 kA (EQ 5.23)

The base unit for current (refer to the FlexElements section in this chapter for additional details) is:
I BASE = 5 kA (EQ 5.24)

The minimum and maximum power values to be monitored (in pu) are:

minimum current = 0 kA- = 0 pu, maximum current = 6.3 kA- = 1.26 pu

----------- ---------------- (EQ 5.25)
5 kA 5 kA

DCMA OUTPUT H2 RANGE: “4 to 20 mA”
DCMA OUTPUT H2 MIN VAL: “0.000 pu”

The worst-case error for this application could be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or ± 0.005 × ( 20 – 4 ) × 6.3 kA = ± 0.504 kA
• ±0.25% of reading or ±0.1% of rated (whichever is greater) for currents between 0.1 and 2.0 of nominal

For example, at the reading of 4.2 kA, the worst-case error is max(0.0025 × 4.2 kA, 0.001 × 5 kA) + 0.504 kA = 0.515 kA.
EXAMPLE 3:
A positive-sequence voltage on a 400 kV system measured via Source 2 is to be monitored by the dcmA H3 output with a
range of 0 to 1 mA. The VT secondary setting is 66.4 V, the VT ratio setting is 6024, and the VT connection setting is
“Delta”. The voltage should be monitored in the range from 70% to 110% of nominal.
The minimum and maximum positive-sequence voltages to be monitored are:
400 kV 400 kV
V min = 0.7 × ------------------- = 161.66 kV, V max = 1.1 × ------------------- = 254.03 kV (EQ 5.26)
3 3
The base unit for voltage (refer to the FlexElements section in this chapter for additional details) is:
V BASE = 0.0664 kV × 6024 = 400 kV (EQ 5.27)

The minimum and maximum voltage values to be monitored (in pu) are:

minimum voltage = 161.66 kV- = 0.404 pu, maximum voltage = 254.03 kV- = 0.635 pu
-------------------------- -------------------------- (EQ 5.28)
400 kV 400 kV
The following settings should be entered:
DCMA OUTPUT H3 SOURCE: “SRC 2 V_1 mag”
DCMA OUTPUT H3 RANGE: “0 to 1 mA”
DCMA OUTPUT H3 MIN VAL: “0.404 pu”
DCMA OUTPUT H3 MAX VAL: “0.635 pu”

The limit settings differ from the expected 0.7 pu and 1.1 pu because the relay calculates the positive-sequence quantities
scaled to the phase-to-ground voltages, even if the VTs are connected in “Delta” (refer to the Metering Conventions section
in Chapter 6), while at the same time the VT nominal voltage is 1 pu for the settings. Consequently the settings required in 5
this example differ from naturally expected by the factor of 3 .
The worst-case error for this application could be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or ± 0.005 × ( 1 – 0 ) × 254.03 kV = ± 1.27 kV
• ±0.5% of reading
For example, under nominal conditions, the positive-sequence reads 230.94 kV and the worst-case error is
0.005 x 230.94 kV + 1.27 kV = 2.42 kV.

MESSAGE
On

The relay provides test settings to verify that functionality using simulated conditions for contact inputs and outputs. The
Test Mode is indicated on the relay faceplate by a flashing Test Mode LED indicator.
To initiate the Test mode, the TEST MODE FUNCTION setting must be “Enabled” and the TEST MODE INITIATE setting must be
set to Logic 1. In particular:
• To initiate Test Mode through relay settings, set TEST MODE INITIATE to “On”. The Test Mode starts when the TEST MODE
FUNCTION setting is changed from “Disabled” to “Enabled”.

• To initiate Test Mode through a user-programmable condition, such as FlexLogic™ operand (pushbutton, digital input,
communication-based input, or a combination of these), set TEST MODE FUNCTION to “Enabled” and set TEST MODE INI-
TIATE to the desired operand. The Test Mode starts when the selected operand assumes a Logic 1 state.

When in Test Mode, the F35 remains fully operational, allowing for various testing procedures. In particular, the protection
and control elements, FlexLogic™, and communication-based inputs and outputs function normally.
The only difference between the normal operation and the Test Mode is the behavior of the input and output contacts. The
former can be forced to report as open or closed or remain fully operational; the latter can be forced to open, close, freeze,
or remain fully operational. The response of the digital input and output contacts to the Test Mode is programmed individu-
5 ally for each input and output using the Force Contact Inputs and Force Contact Outputs test functions described in the fol-
lowing sections.

The relay digital inputs (contact inputs) could be pre-programmed to respond to the Test Mode in the following ways:
• If set to “Disabled”, the input remains fully operational. It is controlled by the voltage across its input terminals and can
be turned on and off by external circuitry. This value should be selected if a given input must be operational during the
test. This includes, for example, an input initiating the test, or being a part of a user pre-programmed test sequence.
• If set to “Open”, the input is forced to report as opened (Logic 0) for the entire duration of the Test Mode regardless of
the voltage across the input terminals.
• If set to “Closed”, the input is forced to report as closed (Logic 1) for the entire duration of the Test Mode regardless of
the voltage across the input terminals.
The Force Contact Inputs feature provides a method of performing checks on the function of all contact inputs. Once
enabled, the relay is placed into Test Mode, allowing this feature to override the normal function of contact inputs. The Test
Mode LED will be On, indicating that the relay is in Test Mode. The state of each contact input may be programmed as “Dis-
abled”, “Open”, or “Closed”. All contact input operations return to normal when all settings for this feature are disabled.

The relay contact outputs can be pre-programmed to respond to the Test Mode.
If set to “Disabled”, the contact output remains fully operational. If operates when its control operand is Logic 1 and will
resets when its control operand is Logic 0. If set to “Energize”, the output will close and remain closed for the entire duration
of the Test Mode, regardless of the status of the operand configured to control the output contact. If set to “De-energize”,
the output will open and remain opened for the entire duration of the Test Mode regardless of the status of the operand con-
figured to control the output contact. If set to “Freeze”, the output retains its position from before entering the Test Mode,
regardless of the status of the operand configured to control the output contact.
These settings are applied two ways. First, external circuits may be tested by energizing or de-energizing contacts. Sec-
ond, by controlling the output contact state, relay logic may be tested and undesirable effects on external circuits avoided.
Example 1: Initiating a Test from User-Programmable Pushbutton 1
The Test Mode should be initiated from User-Programmable Pushbutton 1. The pushbutton will be programmed as
“Latched” (pushbutton pressed to initiate the test, and pressed again to terminate the test). During the test, Digital Input 1
5
should remain operational, Digital Inputs 2 and 3 should open, and Digital Input 4 should close. Also, Contact Output 1
should freeze, Contact Output 2 should open, Contact Output 3 should close, and Contact Output 4 should remain fully
operational. The required settings are shown below.
To enable User-Programmable Pushbutton 1 to initiate the Test mode, make the following changes in the SETTINGS
TESTING TEST MODE menu:

TEST MODE FUNCTION: “Enabled” and TEST MODE INITIATE: “PUSHBUTTON 1 ON”
Make the following changes to configure the Contact I/Os. In the SETTINGS TESTING FORCE CONTACT INPUTS and
FORCE CONTACT INPUTS menus, set:

FORCE Cont Ip 1: “Disabled”, FORCE Cont Ip 2: “Open”, FORCE Cont Ip 3: “Open”, and FORCE Cont Ip 4: “Closed”
FORCE Cont Op 1: “Freeze”, FORCE Cont Op 2: “De-energized”, FORCE Cont Op 3: “Open”, and FORCE Cont Op 4: “Disabled”

Example 2: Initiating a Test from User-Programmable Pushbutton 1 or through Remote Input 1

The Test should be initiated locally from User-Programmable Pushbutton 1 or remotely through Remote Input 1. Both the
pushbutton and the remote input will be programmed as “Latched”. The required settings are shown below.
Write the following FlexLogic™ equation (EnerVista UR Setup example shown):

Set the User Programmable Pushbutton as latching by changing SETTINGS PRODUCT SETUP USER-PROGRAMMABLE

The AVERAGE MSG RETURN TIME is the time taken for direct output messages to return to the sender in a direct input/output
ring configuration (this value is not applicable for non-ring configurations). This is a rolling average calculated for the last 10
messages. There are two return times for dual-channel communications modules.
The UNRETURNED MSG COUNT values (one per communications channel) count the direct output messages that do not
make the trip around the communications ring. The CRC FAIL COUNT values (one per communications channel) count the
direct output messages that have been received but fail the CRC check. High values for either of these counts may indicate
on a problem with wiring, the communication channel, or the relay(s). The UNRETURNED MSG COUNT and CRC FAIL COUNT

b) UR CONVENTION FOR MEASURING PHASE ANGLES

All phasors calculated by UR-series relays and used for protection, control and metering functions are rotating phasors that
maintain the correct phase angle relationships with each other at all times.
For display and oscillography purposes, all phasor angles in a given relay are referred to an AC input channel pre-selected
by the SETTINGS SYSTEM SETUP POWER SYSTEM FREQUENCY AND PHASE REFERENCE setting. This setting
defines a particular source to be used as the reference.
The relay will first determine if any “Phase VT” bank is indicated in the Source. If it is, voltage channel VA of that bank is
used as the angle reference. Otherwise, the relay determines if any “Aux VT” bank is indicated; if it is, the auxiliary voltage
channel of that bank is used as the angle reference. If neither of the two conditions is satisfied, then two more steps of this
hierarchical procedure to determine the reference signal include “Phase CT” bank and “Ground CT” bank.
If the AC signal pre-selected by the relay upon configuration is not measurable, the phase angles are not referenced. The
phase angles are assigned as positive in the leading direction, and are presented as negative in the lagging direction, to
more closely align with power system metering conventions. This is illustrated below.

c) UR CONVENTION FOR MEASURING SYMMETRICAL COMPONENTS

The UR-series of relays calculate voltage symmetrical components for the power system phase A line-to-neutral voltage,
and symmetrical components of the currents for the power system phase A current. Owing to the above definition, phase
angle relations between the symmetrical currents and voltages stay the same irrespective of the connection of instrument
transformers. This is important for setting directional protection elements that use symmetrical voltages.
For display and oscillography purposes the phase angles of symmetrical components are referenced to a common refer-
ence as described in the previous sub-section.
WYE-Connected Instrument Transformers:

Six identical Source menus are available. The "SRC 1" text will be replaced by whatever name was programmed by the
user for the associated source (see SETTINGS SYSTEM SETUP SIGNAL SOURCES).

The relay measures (absolute values only) SOURCE DEMAND on each phase and average three phase demand for real,
reactive, and apparent power. These parameters can be monitored to reduce supplier demand penalties or for statistical
metering purposes. Demand calculations are based on the measurement type selected in the SETTINGS PRODUCT SETUP
DEMAND menu. For each quantity, the relay displays the demand over the most recent demand time interval, the maxi-
mum demand since the last maximum demand reset, and the time and date stamp of this maximum demand value. Maxi-
mum demand quantities can be reset to zero with the CLEAR RECORDS CLEAR DEMAND RECORDS command.

SOURCE FREQUENCY is measured via software-implemented zero-crossing detection of an AC signal. The signal is either a
Clarke transformation of three-phase voltages or currents, auxiliary voltage, or ground current as per source configuration
(see the SYSTEM SETUP POWER SYSTEM settings). The signal used for frequency estimation is low-pass filtered. The
final frequency measurement is passed through a validation filter that eliminates false readings due to signal distortions and
transients.
The technique used to extract the 2nd to 25th VOLTAGE HARMONICS is as follows. Each harmonic is computer per-phase,
where:

N = 64 is the number of samples per cycle

ω0 = 2πf is the angular frequency based on the system frequency (50 or 60 Hz)
k = 1, 2,..., N – 1 is the index over one cycle for the FFT
m is the last sample number for the sliding window
h = 1, 2,..., 25 is the harmonic number
The short-time Fourier transform is applied to the unfiltered signal:

F ampl ( m, h ) = F real ( m, h ) + F imag ( m, h )

The harmonics are a percentage of the fundamental signal obtained by multiplying the amplitudes obtained above 100%.

The latest 15 fault reports can be stored. The most recent fault location calculation (when applicable) is displayed in this
menu, along with the date and time stamp of the event which triggered the calculation. See the SETTINGS PRODUCT
SETUP FAULT REPORTS FAULT REPORT 1(5) menu for assigning the source and trigger for fault calculations. Refer to
the COMMANDS CLEAR RECORDS menu for manual clearing of the fault reports and to the SETTINGS PRODUCT SETUP
CLEAR RELAY RECORDS menu for automated clearing of the fault reports.

The fault locator does not report fault type or location if the source VTs are connected in the Delta configuration.

NOTE

Fault type determination is required for calculation of fault location – the algorithm uses the angle between the negative and 6
positive sequence components of the relay currents. To improve accuracy and speed of operation, the fault components of
the currents are used, i.e., the pre-fault phasors are subtracted from the measured current phasors. In addition to the angle
relationships, certain extra checks are performed on magnitudes of the negative and zero-sequence currents.
The single-ended fault location method assumes that the fault components of the currents supplied from the local (A) and
remote (B) systems are in phase. The figure below shows an equivalent system for fault location.

Local distance to fault Remote

Bus Bus
ZA IA mZ (1 – m)Z IB ZB

EA VF RF EB
VA VB

Figure 6–4: EQUIVALENT SYSTEM FOR FAULT LOCATION

The following equations hold true for this equivalent system.
VA = m ⋅ Z ⋅ IA + RF ⋅ ( IA + IB ) (EQ 6.3)

where: m = sought pu distance to fault, Z = positive sequence impedance of the line.

The currents from the local and remote systems can be parted between their fault (F) and pre-fault load (pre) components:
I A = I AF + I Apre (EQ 6.4)

GE Multilin F35 Multiple Feeder Management Relay 6-17

 6.4 RECORDS 6 ACTUAL VALUES

and neglecting shunt parameters of the line:

I B = I BF – I Apre (EQ 6.5)

Inserting the IA and IB equations into the VA equation and solving for the fault resistance yields:
VA – m ⋅ Z ⋅ IA
R F = ----------------------------------- (EQ 6.6)
I BF⎞
I AF ⋅ ⎛ 1 + ------- -
⎝ I AF⎠
Assuming the fault components of the currents, IAF and IBF are in phase, and observing that the fault resistance, as imped-
ance, does not have any imaginary part gives:
VA – m ⋅ Z ⋅ IA
Im ⎛⎝ -----------------------------------⎞⎠ = 0 (EQ 6.7)
I AF

where: Im() represents the imaginary part of a complex number. Solving the above equation for the unknown m creates the
following fault location algorithm:

Im ( V A ⋅ I AF∗ )
m = ---------------------------------------
- (EQ 6.8)
Im ( Z ⋅ I A ⋅ I AF∗ )
where * denotes the complex conjugate and I AF = I A – I Apre .
Depending on the fault type, appropriate voltage and current signals are selected from the phase quantities before applying
the two equations above (the superscripts denote phases, the subscripts denote stations):
A A
• For AG faults: V A = V A , I A = I A + K 0 ⋅ I 0A
B B
• For BG faults: V A = V A , I A = I A + K 0 ⋅ I 0A
C BC
• For CG faults: V A = V A , I A = I A + K 0 ⋅ I 0A
A B A B
• For AB and ABG faults: V A = V A – V A , IA = IA – IA
B C B C
• For BC and BCG faults: V A = V A – V A , IA = IA – IA
C A C A
6 • For CA and CAG faults: V A = V A – V A , I A = I A – I A
where K0 is the zero sequence compensation factor (for the first six equations above)
• For ABC faults, all three AB, BC, and CA loops are analyzed and the final result is selected based upon consistency of
the results
The element calculates the distance to the fault (with m in miles or kilometers) and the phases involved in the fault.

• the critical fail relay on the power supply module is de-energized
• all other output relays are de-energized and are prevented from further operation
• the faceplate In Service LED indicator is turned off
• a RELAY OUT OF SERVICE event is recorded

 APPENDIX B B.1 MODBUS RTU PROTOCOL

APPENDIX B MODBUS COMMUNICATIONSB.1MODBUS RTU PROTOCOL B.1.1 INTRODUCTION

The UR-series relays support a number of communications protocols to allow connection to equipment such as personal
computers, RTUs, SCADA masters, and programmable logic controllers. The Modicon Modbus RTU protocol is the most
basic protocol supported by the UR. Modbus is available via RS232 or RS485 serial links or via ethernet (using the Mod-
bus/TCP specification). The following description is intended primarily for users who wish to develop their own master com-
munication drivers and applies to the serial Modbus RTU protocol. Note that:
• The UR always acts as a slave device, meaning that it never initiates communications; it only listens and responds to B
requests issued by a master computer.
• For Modbus®, a subset of the Remote Terminal Unit (RTU) protocol format is supported that allows extensive monitor-
ing, programming, and control functions using read and write register commands.

B.1.2 PHYSICAL LAYER

The Modbus® RTU protocol is hardware-independent so that the physical layer can be any of a variety of standard hard-
ware configurations including RS232 and RS485. The relay includes a faceplate (front panel) RS232 port and two rear ter-
minal communications ports that may be configured as RS485, fiber optic, 10BaseT, or 10BaseF. Data flow is half-duplex in
all configurations. See Chapter 3 for details on wiring.
Each data byte is transmitted in an asynchronous format consisting of 1 start bit, 8 data bits, 1 stop bit, and possibly 1 parity
bit. This produces a 10 or 11 bit data frame. This can be important for transmission through modems at high bit rates (11 bit
data frames are not supported by many modems at baud rates greater than 300).
The baud rate and parity are independently programmable for each communications port. Baud rates of 300, 1200, 2400,
4800, 9600, 14400, 19200, 28800, 33600, 38400, 57600, or 115200 bps are available. Even, odd, and no parity are avail-
able. Refer to the Communications section of Chapter 5 for further details.
The master device in any system must know the address of the slave device with which it is to communicate. The relay will
not act on a request from a master if the address in the request does not match the relay’s slave address (unless the
address is the broadcast address – see below).
A single setting selects the slave address used for all ports, with the exception that for the faceplate port, the relay will
accept any address when the Modbus® RTU protocol is used.

B.1.3 DATA LINK LAYER

Communications takes place in packets which are groups of asynchronously framed byte data. The master transmits a
packet to the slave and the slave responds with a packet. The end of a packet is marked by ‘dead-time’ on the communica-
tions line. The following describes general format for both transmit and receive packets. For exact details on packet format-
ting, refer to subsequent sections describing each function code.

Table B–1: MODBUS PACKET FORMAT

DESCRIPTION SIZE
SLAVE ADDRESS 1 byte
FUNCTION CODE 1 byte
DATA N bytes
CRC 2 bytes
DEAD TIME 3.5 bytes transmission time

• SLAVE ADDRESS: This is the address of the slave device that is intended to receive the packet sent by the master
and to perform the desired action. Each slave device on a communications bus must have a unique address to prevent
bus contention. All of the relay’s ports have the same address which is programmable from 1 to 254; see Chapter 5 for
details. Only the addressed slave will respond to a packet that starts with its address. Note that the faceplate port is an
exception to this rule; it will act on a message containing any slave address.
A master transmit packet with slave address 0 indicates a broadcast command. All slaves on the communication link
take action based on the packet, but none respond to the master. Broadcast mode is only recognized when associated
with Function Code 05h. For any other function code, a packet with broadcast mode slave address 0 will be ignored.

GE Multilin F35 Multiple Feeder Management Relay B-1

 B.1 MODBUS RTU PROTOCOL APPENDIX B

• FUNCTION CODE: This is one of the supported functions codes of the unit which tells the slave what action to per-
form. See the Supported Function Codes section for complete details. An exception response from the slave is indi-
cated by setting the high order bit of the function code in the response packet. See the Exception Responses section
for further details.
• DATA: This will be a variable number of bytes depending on the function code. This may include actual values, set-
tings, or addresses sent by the master to the slave or by the slave to the master.
• CRC: This is a two byte error checking code. The RTU version of Modbus® includes a 16-bit cyclic redundancy check
B (CRC-16) with every packet which is an industry standard method used for error detection. If a Modbus slave device
receives a packet in which an error is indicated by the CRC, the slave device will not act upon or respond to the packet
thus preventing any erroneous operations. See the CRC-16 Algorithm section for details on calculating the CRC.
• DEAD TIME: A packet is terminated when no data is received for a period of 3.5 byte transmission times (about 15 ms
at 2400 bps, 2 ms at 19200 bps, and 300 µs at 115200 bps). Consequently, the transmitting device must not allow gaps
between bytes longer than this interval. Once the dead time has expired without a new byte transmission, all slaves
start listening for a new packet from the master except for the addressed slave.

B.1.4 CRC-16 ALGORITHM

The CRC-16 algorithm essentially treats the entire data stream (data bits only; start, stop and parity ignored) as one contin-
uous binary number. This number is first shifted left 16 bits and then divided by a characteristic polynomial
(11000000000000101B). The 16 bit remainder of the division is appended to the end of the packet, MSByte first. The
resulting packet including CRC, when divided by the same polynomial at the receiver will give a zero remainder if no trans-
mission errors have occurred. This algorithm requires the characteristic polynomial to be reverse bit ordered. The most sig-
nificant bit of the characteristic polynomial is dropped, since it does not affect the value of the remainder.
A C programming language implementation of the CRC algorithm will be provided upon request.

 APPENDIX B B.2 FUNCTION CODES

B.2FUNCTION CODES B.2.1 SUPPORTED FUNCTION CODES

Modbus® officially defines function codes from 1 to 127 though only a small subset is generally needed. The relay supports
some of these functions, as summarized in the following table. Subsequent sections describe each function code in detail.

FUNCTION CODE MODBUS DEFINITION GE MULTILIN DEFINITION

HEX
03
DEC
3 Read Holding Registers Read Actual Values or Settings
B
04 4 Read Holding Registers Read Actual Values or Settings
05 5 Force Single Coil Execute Operation
06 6 Preset Single Register Store Single Setting
10 16 Preset Multiple Registers Store Multiple Settings

B.2.2 READ ACTUAL VALUES OR SETTINGS (FUNCTION CODE 03/04H)

This function code allows the master to read one or more consecutive data registers (actual values or settings) from a relay.
Data registers are always 16 bit (two byte) values transmitted with high order byte first. The maximum number of registers
that can be read in a single packet is 125. See the Modbus Memory Map table for exact details on the data registers.
Since some PLC implementations of Modbus® only support one of function codes 03h and 04h, the relay interpretation
allows either function code to be used for reading one or more consecutive data registers. The data starting address will
determine the type of data being read. Function codes 03h and 04h are therefore identical.
The following table shows the format of the master and slave packets. The example shows a master device requesting 3
register values starting at address 4050h from slave device 11h (17 decimal); the slave device responds with the values 40,
300, and 0 from registers 4050h, 4051h, and 4052h, respectively.

 B.3 FILE TRANSFERS APPENDIX B

B.3FILE TRANSFERS B.3.1 OBTAINING RELAY FILES VIA MODBUS

a) INTRODUCTION
The UR relay has a generic file transfer facility, meaning that you use the same method to obtain all of the different types of
files from the unit. The Modbus registers that implement file transfer are found in the "Modbus File Transfer (Read/Write)"
and "Modbus File Transfer (Read Only)" modules, starting at address 3100 in the Modbus Memory Map. To read a file from
the UR relay, use the following steps:
B 1. Write the filename to the "Name of file to read" register using a write multiple registers command. If the name is shorter
than 80 characters, you may write only enough registers to include all the text of the filename. Filenames are not case
sensitive.
2. Repeatedly read all the registers in "Modbus File Transfer (Read Only)" using a read multiple registers command. It is
not necessary to read the entire data block, since the UR relay will remember which was the last register you read. The
"position" register is initially zero and thereafter indicates how many bytes (2 times the number of registers) you have
read so far. The "size of..." register indicates the number of bytes of data remaining to read, to a maximum of 244.
3. Keep reading until the "size of..." register is smaller than the number of bytes you are transferring. This condition indi-
cates end of file. Discard any bytes you have read beyond the indicated block size.
4. If you need to re-try a block, read only the "size of.." and "block of data", without reading the position. The file pointer is
only incremented when you read the position register, so the same data block will be returned as was read in the pre-
vious operation. On the next read, check to see if the position is where you expect it to be, and discard the previous
block if it is not (this condition would indicate that the UR relay did not process your original read request).
The UR relay retains connection-specific file transfer information, so files may be read simultaneously on multiple Modbus
connections.

b) OTHER PROTOCOLS
All the files available via Modbus may also be retrieved using the standard file transfer mechanisms in other protocols (for
example, TFTP or MMS).

c) COMTRADE, OSCILLOGRAPHY, AND DATA LOGGER FILES

Oscillography and data logger files are formatted using the COMTRADE file format per IEEE PC37.111 Draft 7c (02 Sep-
tember 1997). The files may be obtained in either text or binary COMTRADE format.

d) READING OSCILLOGRAPHY FILES

Familiarity with the oscillography feature is required to understand the following description. Refer to the Oscillography sec-
tion in Chapter 5 for additional details.
The Oscillography Number of Triggers register is incremented by one every time a new oscillography file is triggered (cap-
tured) and cleared to zero when oscillography data is cleared. When a new trigger occurs, the associated oscillography file
is assigned a file identifier number equal to the incremented value of this register; the newest file number is equal to the
Oscillography_Number_of_Triggers register. This register can be used to determine if any new data has been captured by
periodically reading it to see if the value has changed; if the number has increased then new data is available.
The Oscillography Number of Records register specifies the maximum number of files (and the number of cycles of data
per file) that can be stored in memory of the relay. The Oscillography Available Records register specifies the actual num-
ber of files that are stored and still available to be read out of the relay.
Writing “Yes” (i.e. the value 1) to the Oscillography Clear Data register clears oscillography data files, clears both the Oscil-
lography Number of Triggers and Oscillography Available Records registers to zero, and sets the Oscillography Last
Cleared Date to the present date and time.
To read binary COMTRADE oscillography files, read the following filenames:
OSCnnnn.CFG and OSCnnn.DAT
Replace “nnn” with the desired oscillography trigger number. For ASCII format, use the following file names
OSCAnnnn.CFG and OSCAnnn.DAT

B-6 F35 Multiple Feeder Management Relay GE Multilin

 APPENDIX B B.3 FILE TRANSFERS

e) READING DATA LOGGER FILES

Familiarity with the data logger feature is required to understand this description. Refer to the Data Logger section of Chap-
ter 5 for details. To read the entire data logger in binary COMTRADE format, read the following files.
datalog.cfg and datalog.dat
To read the entire data logger in ASCII COMTRADE format, read the following files.
dataloga.cfg and dataloga.dat
To limit the range of records to be returned in the COMTRADE files, append the following to the filename before writing it:
B
• To read from a specific time to the end of the log: <space> startTime
• To read a specific range of records: <space> startTime <space> endTime
• Replace <startTime> and <endTime> with Julian dates (seconds since Jan. 1 1970) as numeric text.

f) READING EVENT RECORDER FILES

To read the entire event recorder contents in ASCII format (the only available format), use the following filename:
EVT.TXT
To read from a specific record to the end of the log, use the following filename:
EVTnnn.TXT (replace nnn with the desired starting record number)
To read from a specific record to another specific record, use the following filename:
EVT.TXT xxxxx yyyyy (replace xxxxx with the starting record number and yyyyy with the ending record number)

B.3.2 MODBUS PASSWORD OPERATION

The COMMAND password is set up at memory location 4000. Storing a value of “0” removes COMMAND password protec-
tion. When reading the password setting, the encrypted value (zero if no password is set) is returned. COMMAND security
is required to change the COMMAND password. Similarly, the SETTING password is set up at memory location 4002.
These are the same settings and encrypted values found in the SETTINGS PRODUCT SETUP PASSWORD SECURITY
menu via the keypad. Enabling password security for the faceplate display will also enable it for Modbus, and vice-versa.
To gain COMMAND level security access, the COMMAND password must be entered at memory location 4008. To gain
SETTING level security access, the SETTING password must be entered at memory location 400A. The entered SETTING
password must match the current SETTING password setting, or must be zero, to change settings or download firmware.
COMMAND and SETTING passwords each have a 30-minute timer. Each timer starts when you enter the particular pass-
word, and is re-started whenever you “use” it. For example, writing a setting re-starts the SETTING password timer and
writing a command register or forcing a coil re-starts the COMMAND password timer. The value read at memory location
4010 can be used to confirm whether a COMMAND password is enabled or disabled (0 for Disabled). The value read at
memory location 4011 can be used to confirm whether a SETTING password is enabled or disabled.
COMMAND or SETTING password security access is restricted to the particular port or particular TCP/IP connection on
which the entry was made. Passwords must be entered when accessing the relay through other ports or connections, and
the passwords must be re-entered after disconnecting and re-connecting on TCP/IP.

F011 FLOATING_POINT IEEE FLOATING POINT (32 bits)
UR_UINT16 FLEXCURVE DATA (120 points)
A FlexCurve is an array of 120 consecutive data points (x, y) which
F070
are interpolated to generate a smooth curve. The y-axis is the user
HEX2 2 BYTES - 4 ASCII DIGITS
defined trip or operation time setting; the x-axis is the pickup ratio
and is pre-defined. Refer to format F119 for a listing of the pickup
ratios; the enumeration value for the pickup ratio indicates the off-
F071
set into the FlexCurve base address where the corresponding time HEX4 4 BYTES - 8 ASCII DIGITS
value is stored.

F072

HEX6 6 BYTES - 12 ASCII DIGITS
DISPLAY_SCALE DISPLAY SCALING
(unsigned 16-bit integer)
MSB indicates the SI units as a power of ten. LSB indicates the F073
number of decimal points to display. HEX8 8 BYTES - 16 ASCII DIGITS
Example: Current values are stored as 32 bit numbers with three
decimal places and base units in Amps. If the retrieved value is
F074
12345.678 A and the display scale equals 0x0302 then the dis-
HEX20 20 BYTES - 40 ASCII DIGITS
played value on the unit is 12.35 kA.

 APPENDIX C C.1 INTRODUCTION

APPENDIX C IEC 61850 COMMUNICATIONSC.1INTRODUCTION C.1.1 OVERVIEW

The IEC 61850 standard is the result of years of work by electric utilities and vendors of electronic equipment to produce
standardized communications systems. IEC 61850 is a series of standards describing client/server and peer-to-peer com-
munications, substation design and configuration, testing, environmental and project standards. The complete set includes:
• IEC 61850-1: Introduction and overview
• IEC 61850-2: Glossary
• IEC 61850-3: General requirements
• IEC 61850-4: System and project management
• IEC 61850-5: Communications and requirements for functions and device models
•
•

• IEC 61850-10: Conformance testing
These documents can be obtained from the IEC (http://www.iec.ch). It is strongly recommended that all those involved with
any IEC 61850 implementation obtain this document set.

C.1.2 COMMUNICATION PROFILES

The F35 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks.
The TP4/CLNP profile requires the F35 to have a network address or Network Service Access Point (NSAP) to establish a
communication link. The TCP/IP profile requires the F35 to have an IP address to establish communications. These
addresses are located in the SETTINGS PRODUCT SETUP COMMUNICATIONS NETWORK menu. Note that the F35
supports IEC 61850 over the TP4/CLNP or TCP/IP stacks, and also operation over both stacks simultaneously. It is possi-
ble to have up to four simultaneous connections (in addition to DNP and Modbus/TCP (non-IEC 61850) connections).

C.1.3 MMS PROTOCOL

IEC 61850 specifies the use of the Manufacturing Message Specification (MMS) at the upper (application) layer for transfer
of real-time data. This protocol has been in existence for a number of years and provides a set of services suitable for the
transfer of data within a substation LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser-
vices in IEC 61850-8-1.

C.1.4 PEER-TO-PEER COMMUNICATION

Peer-to-peer communication of digital state information (remote inputs/outputs) is supported using the IEC 61850 GSSE
and GOOSE services. This feature allows digital points to be exchanged between IEC 61850 conforming devices.

C.1.5 FILE SERVICES

MMS file services are supported to allow transfer of oscillography, event record, or other files from a F35 relay.

GE Multilin F35 Multiple Feeder Management Relay C-1

 C.1 INTRODUCTION APPENDIX C

C.1.6 COMMUNICATION SOFTWARE UTILITIES

The exact structure and values of the supported IEC 61850 logical nodes can be seen by connecting to a F35 relay with an
MMS browser, such as the “MMS Object Explorer and AXS4-MMS” DDE/OPC server from Sisco Inc.

C.1.7 NON-IEC 61850 DATA

The F35 relay makes available a number of non-IEC 61850 data items. These data items can be accessed through the
“UR” MMS domain. IEC 61850 data can be accessed through the “IECDevice” MMS domain (IEC 61850 logical device).

C.1.8 TCP CONNECTION TIMING

C A built-in TCP/IP connection timeout of two minutes is employed by the F35 to detect ‘dead’ connections. If there is no data
traffic on a TCP connection for greater than two minutes, the connection will be aborted by the F35. This frees up the con-
nection to be used by other clients. Therefore, when using IEC 61850 reporting, clients should configure report control
block items such that an integrity report will be issued at least every 2 minutes (120000 ms). This ensures that the F35 will
not abort the connection. If other MMS data is being polled on the same connection at least once every 2 minutes, this tim-
eout will not apply.

C.1.9 LOGICAL NODE MMXU DATA MAPPING

The mapping of F35 relay data to IEC 61850 MMXU data is performed on a per-source basis. MMXU1 data originates from
F35 source 1, MMXU2 data originates from F35 source 2, etc.

C.1.10 LOGICAL NODE GGIO DATA MAPPING

Logical node GGIO1 data is mapped using the F35 Flexstate parameters. Each single point indication in GGIO1 can be
selected using the corresponding Flexstate parameter setting. For example, the value of GGIO1 point “Ind3” is determined
from the FlexLogic™ operand selected in the Flexstate parameter 3 setting. Thus, GGIO1 data can originate as any Flex-
Logic™ parameter.
Logical node GGIO2 data is mapped to the F35 virtual inputs. Each single point control in GGIO2 is mapped to a virtual
input. For example, GGIO2 control point SPCSO3 is mapped to virtual input 3.

C.1.11 OTHER LOGICAL NODE MAPPING

All other IEC 61850 logical nodes (with the exception of PTRC) are associated with standard UR-series relay protection
elements and features. The following mapping is used (for applicable elements):
• PIOC: phase instantaneous overcurrent, neutral instantaneous overcurrent, ground instantaneous overcurrent, nega-
tive sequence instantaneous overcurrent
• PTOC: phase time overcurrent, neutral time overcurrent, ground time overcurrent, negative sequence time overcur-
rent, neutral directional overcurrent, negative sequence directional overcurrent
• PTUV: phase undervoltage, auxiliary undervoltage, third harmonic neutral undervoltage
• PTOV: phase overvoltage, neutral overvoltage, auxiliary overvoltage, negative sequence overvoltage
• RREC: autoreclosure
• RFLO: fault locator

tion in the UR; that is, the appropriate Virtual Input is put into the “On” state. If the Virtual Input is set to “Self-Reset”,
it will reset after one pass of FlexLogic™. The On/Off times and Count value are ignored. “Pulse Off” and “Latch Off”
operations put the appropriate Virtual Input into the “Off” state. “Trip” and “Close” operations both put the appropriate
Virtual Input into the “On” state.

E.1.2 IMPLEMENTATION TABLE

The following table identifies the variations, function codes, and qualifiers supported by the F35 in both request messages
and in response messages. For static (non-change-event) objects, requests sent with qualifiers 00, 01, 06, 07, or 08, will be
responded with qualifiers 00 or 01. Static object requests sent with qualifiers 17 or 28 will be responded with qualifiers 17 or
28. For change-event objects, qualifiers 17 or 28 are always responded.

Note 1: A default variation refers to the variation responded when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. The default varia-
tions for object types 1, 2, 20, 21, 22, 23, 30, and 32 are selected via relay settings. Refer to the Communications section in Chapter 5
for details. This optimizes the class 0 poll data size.
Note 2: For static (non-change-event) objects, qualifiers 17 or 28 are only responded when a request is sent with qualifiers 17 or 28, respec-
tively. Otherwise, static object requests sent with qualifiers 00, 01, 06, 07, or 08, will be responded with qualifiers 00 or 01 (for change-
event objects, qualifiers 17 or 28 are always responded.)
Note 3: Cold restarts are implemented the same as warm restarts – the F35 is not restarted, but the DNP process is restarted.

A counter freeze command has no meaning for counters 8 and 9. F35 Digital Counter values are represented as 32-bit inte-
gers. The DNP 3.0 protocol defines counters to be unsigned integers. Care should be taken when interpreting negative
counter values.

 APPENDIX E E.2 DNP POINT LISTS

E.2.4 ANALOG INPUTS

The DNP analog input data points are configured through the PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT
LISTS ANALOG INPUT / MME POINTS menu. Refer to the Communications section of Chapter 5 for additional details.

It is important to note that 16-bit and 32-bit variations of analog inputs are transmitted through DNP as signed numbers.
Even for analog input points that are not valid as negative values, the maximum positive representation is 32767 for 16-bit
values and 2147483647 for 32-bit values. This is a DNP requirement.
The deadbands for all Analog Input points are in the same units as the Analog Input quantity. For example, an Analog Input
quantity measured in volts has a corresponding deadband in units of volts. This is in conformance with DNP Technical Bul-
letin 9809-001: Analog Input Reporting Deadband. Relay settings are available to set default deadband values according to
data type. Deadbands for individual Analog Input Points can be set using DNP Object 34.
