ing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage,
and (ii) invalidate product certifications or listings.

CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
• Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
• Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
• Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

General Information

Introduction
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The MFR 11 model is a generator or mains protection unit packaged into one compact device. Typical applica-
tions are generators and switchgear equipment that require independent protection architecture. Different options
offer additional functionality

The detailed model description for the MFR 11 reads as follows:

MFR11 10-h0000 B/ ABDEF..Z

Options according to list of options.

These options can be found in the manual. Each chapter headline points out
if the described function is standard or has to be ordered optionally.
Mounting
[B].. Flush-mounting
[M].. DIN-rail/rear panel mounting
Hardware variation
non-standard models; e.g. additional relays
Current transformer, secondary
[0] = not available
Voltage transformer/PTs, secondary
[0] = not available
[1] = 100 Vac
[4] = 400 Vac
[7] = 690 Vac
Type

Examples:
• MFR1110B/U (flush mounted, standard unit with 100 Vac PT inputs with Option U [over-/undervoltage,
voltage asymmetry, and over-/underfrequency monitoring, 3 relay outputs])
• MFR1140B/UVDRN (flush mounted, standard unit with 400 Vac PT inputs with the Options U/V/D/R/N

Measurement Value Logging

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Voltage
Voltage is displayed as three-phase r.m.s measurement of the phase-neutral and/or phase-phase voltages. Op-
tion YC utilizes single-phase r.m.s. measurement of the synchronizing voltage VL1-L2.

This device can be ordered with the following measuring voltage input ranges (rated voltages). Please indi-
cate the measuring voltage input required when ordering (refer to Technical Data on page 60):

• 66 V/115 V.................... [1]

• 230 V/400 V.................... [4]
• 400 V/690 V.................... [7]

Frequency
Frequency measurement is extracted from the digitally filtered measuring voltages. The frequency is meas-
ured three-phase if the measured voltage exceeds 15% of the nominal voltage. This ensures rapid and precise
measurement of the frequency. However the frequency is still measured correctly even if voltage is only ap-
plied to one phase.

NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens, and other details described, which do not exist on your unit, may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. Due to
the large variety of parameter settings, it is not possible to cover every combination. The manual is
therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings may
be taken from the list of parameters enclosed at the rear of this manual.

Chapter 2.
Electrostatic Discharge Awareness

All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.

Follow these precautions when working with or near the control.

1. Before doing maintenance on the electronic control, discharge the static electricity on your body to
ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.).

2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials.
Wear cotton or cotton-blend materials as much as possible because these do not store static electric char-
ges as easily as synthetics.

3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cigarette packages, cello-
phane wrappers, vinyl books or folders, plastic bottles, etc.) away from the control, modules, and work
area as much as possible.

4. Opening the control cover may void the unit warranty.

Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If
you must remove the PCB from the control cabinet, follow these precautions:

• Ensure that the device is completely voltage-free (all connectors have to be disconnected).

• Do not touch any part of the PCB except the edges.

• Do not touch the electrical conductors, connectors, or components with conductive devices or with
bare hands.

• When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you
are ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.

CAUTION
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.

Synchronizing Voltage (Option YC)

NOTE
Connection of the phase voltage L3 to terminal 72 (synchronizing voltage) is necessary if
• the generator voltage is connected as a three-wire-system and
• the power measurement of the generator power must be three-phase.
If the input for balancing the measuring system is not connected, minor inaccuracies will occur during
the three-phase power measurement. Functionality will not be affected if the voltage L3 is not con-
nected and the power measurement is configured as single-phase.

Possible CAN Bus Problems

If no data is transmitted on the CAN bus, check the following for common CAN bus communication problems:

- T structure bus is utilized (stub-end feeders or branch lines are not recommended)
- CAN-L and CAN-H are interchanged
- Not all devices on the bus are using identical Baud rates
- Terminating resistor(s) is/are missing
- Incorrect baud rate (too high) for length of CAN bus

Maximum CAN Bus Length

The maximum length of the communication bus wiring is dependent on the configured Baud rate. Refer to Table
3-2 for the maximum bus length (Source: CANopen; Holger Zeltwanger (Hrsg.); 2001 VDE VERLAG GMBH,
Berlin und Offenbach; ISBN 3-8007-2448-0).

Baud rate Max. length

125 kbit/s 250 m
50 kbits/s 1000 m
20 kbit/s 2500 m
Table 3-2: Maximum CAN bus length

The maximum specified length for the communication bus wiring might not be achieved if poor quality wire is
utilized, there is high contact resistance, or other conditions exist. Reducing the baud rate may overcome these is-
sues.

DPC - Direct Configuration Interface

NOTE
Configuration with the direct configuration cable DPC (P/N 5417-557) is possible. A laptop/PC, the DPC
cable, the program LeoPC1 version 3.1.1 or higher (included on CD Rom with unit), and the proper con-
figuration files are required. Please consult the online help installed when the program is installed for a
description of the LeoPC1 program and its setup.

WARNING
Only the DPC cable may be connected to the DPC interface. If other devices or lines are connected, the
unit may be destroyed. Especially the connection of live lines (like phone lines) will destroy the unit.

CAUTION
The connection cable delivered with the DPC must be used between DPC and the unit to ensure proper
functionality of the unit. An extension or utilization of different cable types for the connection between
the unit and DPC may result a malfunction of the unit. This may possibly result in damage to compo-
nents of the system. If an extension of the data connection line is required, only the serial cable (RS-
232) between DPC and laptop/PC may be extended. It is recommended to use an industry standard ca-
ble for this.

NOTE
If the parameter "Direct config." is enabled on the control, communication via the CAN bus interface on
terminals X1/X5 is disabled.
If the control unit detects that the engine is running (ignition speed exceeded), the direct configuration
port is disabled.

Configuration

Configuration can be performed via the front panel push buttons and the front panel LC display or using a PC
and the PC program LeoPC1 via the serial interface. If direct configuration via a PC is selected, the following
baud rate is to be used:

• Configuration via direct configuration plug = 9,600 Baud (8 Bit, no parity, 1 stop bit)

CAUTION
Please note that configuration only should be done while the system is not in operation.

NOTE
A list of all parameters may be found in Appendix E of this manual.

You can advance through the individual parameter screens if you are in configuration mode (simultaneously
pressing of "Digit↑" and "Cursor→" push buttons permits access to the configuration mode) by using the "Se-
lect" button. If you press and hold the "Select" push button, the scroll function will be activated, allowing for the
parameter screens to be advanced through more rapidly. The control unit will permit the operator to reverse up to
four previous screens (exception: it is not possible to reverse from the first parameter to the last parameter). To
perform the reverse function through the parameter screens, the "Select" and "Cursor→" push buttons must be
pressed and released simultaneously. The control unit will revert to automatic mode if an entry isn’t performed, a
change made, or any other action performed for 120 seconds.

NOTE
There are three different hardware versions described in this operating manual: A 100 V-version [1], a
400 V-version [4] and a 690 V-version [7]. The versions vary as far as the configuration screens and the
parameter input ranges are concerned. The three types are differentiated by indicating the voltage: ([1]
..., [4] ... or [7] ...).

After the configuration mode is enabled, the subsequent screens can be viewed and
modified within the preset limits. Please note, that by depressing the "Select" but-
ton, the following screens are advanced by one screen each. If a parameter is con-
figured "OFF", the related screens are not displayed or monitored by the control.
Pressing the "Select" button will advance the displayed screen to the next parame-
ter.

Password (Starting with Version 2.0xx / 3.0xx)

The unit is equipped with a three-level code and configuration hierarchy, which allows different user access to
the control. A distinction is made between:

Code level CS0 (User Level) Factory password = none

This code level allows for monitoring of the system and does not permit access to the parameters. Configuration
is blocked.

Code level CS1 (Basic Service Level) Factory password = "0 0 0 1"
This code level entitles the user to change selected parameters, like setting Bar/PSI, °C/°F, and clock adjustment.
Changing a password is not permitted at this level. This password expires two hours after entering the password
and the user is returned to the CS0 level.

Code level CS2 (Commissioning Level) Factory password = "0 0 0 2"

Allows direct access to all parameters (displaying and changing). In addition, the user may also set the password
for levels CS1 and CS2. This password expires two hours after entering the password and the user is returned to
the CS0 level.

NOTE
Once the code level is set, it will not be changed even after entering the configuration repeatedly an in-
correct code number has been entered, the code level is set to CS0, thus locking the device for external
persons.
If for 2 hours uninterruptedly supply voltage is applied, the device automatically switches to code
level 0.

NOTE (Starting with Version 2.1xx / 3.1xx)

The following configuration screen "Enter code number" only appears if the parameter "Password Pro-
tection" is configured "ON" (see below).

Enter code Enter code number 0000 to 9999

number 0000
Upon enabling the configuration mode, the user is required to enter an access code
number, which identifies the various users. The displayed number XXXX is a ran-
domly generated number (RN). If the random number is confirmed by pressing the
"Select" button without being changed, the current level of access maintained.
Upon entering either a level 1 or level 2 access code, the corresponding level of ac-
cess is granted. If an incorrect access code is entered the control unit changes to
code level 0 and all access is blocked until a code level 1 or 2 access code is en-
tered.

Password Password protection ON/OFF

Protection ON
ON ................Password protection is enabled. Configuration access is granted by
entering the appropriate password (Code level 1/2). If an incorrect

OFF ..............Password protection is disabled. Access to configuration screens is
permanently set to code level 2 and the code number is not queried.
This parameter can only be changed if the code number of code
level 2 has been entered.

NOTE
This Option YC is not available for 690 V units; refer to Synchronizing Voltage (Option YC) on page 15.

Output of the Signal "Systems are Synchronous"

After the control unit monitors voltages and frequencies are within permissible limits, it will issue a circuit
breaker closure command to connect two systems. The closure command has a predefined minimum on time that
is output to a relay. Relay 3 (or Relay 8 for units with Option YC and Option R) is dedicated to this function. Re-
lay 2 can also be assigned with this function for redundancy purposes starting with SW version 3.1450.

The maximum permissible limits are:

• Generator System (GN): 75% to 112.5% of the rated voltage

• Mains System (MN): 87% to 112.5% of the rated voltage

Function "Synchronization of systems"

The control unit calculates internally the electrical angle of advance to issue the circuit breaker closure command.
The corresponding lead-time remains constant due to the inherent delay of the breaker regardless of the fre-
quency differential of the two systems. If the voltage and frequency differential of the two systems are within
permissible limits, the breaker closure command may be issued under the following conditions:

• The respective monitored voltages of the two systems must be greater than 75 % and less than 112.5 % if the
configured rated voltage.
• The monitored voltage differential of the two systems must fall below the configured maximum permissible
voltage differential.
• The monitored frequency differential of the two systems must fall below the configured maximum permissi-
ble frequency differential
• The electrical angle between two coincident phases must be smaller than the respective permissible error an-
gle (slip-dependent, max. 8 °elec.).

Synchronous Networks

A network is considered as synchronous if the frequency difference between the systems is less than 0.02134 Hz.
The unit also issues a breaker closure order for synchronous networks, as long as the electrical angle between the
two systems does not exceed the maximum permissible phase angle and the monitored voltage differential is less
than the configured maximum permissible voltage differential.

OFF ..............Synchronizing functions have been disabled, and the subsequent
screens of this function are not displayed.

Synchronization Maximum permissible positive slip frequency differential for synchr. 0.02 to 0.49 Hz
df max 0.00Hz
This parameter defines the upper permissible frequency differential limit for syn-
chronization. Prior to the control issuing a breaker closure command, the monitored
frequency differential of the two systems must be less than the value configured
here.
Positive slip refers to the System (GN) frequency being greater than the System
(MN) frequency.

Synchronization Maximum permissible negative slip frequency differential for synchr. 0.00 to -0.49 Hz
df min -0.00Hz
This parameter defines the lower permissible frequency differential limit for syn-
chronization. Prior to the control issuing a breaker closure command, the monitored
frequency differential of the two systems must be greater than the value configured
here.
Negative slip refers to the System (GN) frequency being less than the System (MN)
frequency.

Synchronization Maximum permissible voltage differential 0.1 to 15.0 %

dV max = 00.0%
A close command will not be issued until the measured differential voltage of the
two systems is less than value configured here. An internal hysteresis of 12.5% of
the value configured will be applied to eliminate relay chatter. The percentage con-
figured here is a + or – value.

Synchronization Maximum permissible phase angle 1 to 60°

Max phase < 00
The phase angle in synchronous networks must not exceed the value configured
here to be able to energize the closing relay. If the value configured here is between
55° and 60°, the closing relay will not energize until the phase angle falls below
55°, but it will remain energized until the phase angle exceeds the configured value
even if it is between 55° and 60°.

Synchronization Minimum pulse time of the breaker close relay 50 to 250 ms

Time pulse>000ms
The duration of the breaker closure command is defined by this parameter. The
length of the pulse can be adjusted to the requirements of the individual breaker.
The configured value defines the minimum on time of the pulse.

Gen.circ.breaker Breaker inherent delay 40 to 300 ms

Pick-up t. 000ms
All breakers have an inherent delay. This is the time from when the closure com-
mand is issued until the breaker contacts are closed. This parameter defines that
time. The control unit uses the time value configured here to determine when the
breaker closure command is issued independent of the frequency differential. This
permits the breaker contacts to close as close as possible to the synchronous point.

The following screen will not be displayed, if the parameter "Volt.-Measuring" is configured to

Volt. Monitoring Monitoring for Phase-neutral/Phase to phase

----------------
The unit can either monitor the phase-neutral voltages (four-wire system) or the
phase-phase voltages (three-wire system). Usually, for low-voltage system
(400/690V-version) the phase-neutral voltages are monitored, while for the me-
dium and high-voltage systems (100 V-version), the phase-phase voltages are
monitored. The monitoring of the phase-phase voltages is recommended to avoid a
phase-earth fault in a compensated or isolated mains resulting in the voltage protec-
tion tripping. The only effect on the screen "Voltage measuring" is the one de-
scribed in the above note. The settings in the screen "Volt.-Monitoring" do
have the following effects on the configuration screens:

Phase-neutral The voltage at the terminals 1/2/3/4 (or 1/3/5/6 for 690 V versions)
is measured as a four-wire installation. All subsequent screens con-
cerning voltage measuring refer to phase-neutral voltage (VPh-N). This
is indicated in the configuration screens by the supplement [Phase-
N].
Phase to phase If the voltage system connected to the terminals 1/2/3/4 (or 1/3/5/6
for 690 V versions) is a three-wire system, this setting must be se-
lected. All subsequent screens concerning voltage measuring refer to
phase-phase voltage (VPh-Ph). In the configuration screens, this is in-
dicated by the supplement [V(ph-ph)].

the frequency above the permissible limit, the frequency must drop below that
threshold and the frequency level defined here for the fault condition to be recog-
nized as no longer existing.
Example: If a 60 Hz system has an overfrequency limit of 70 Hz and a hysteresis of
5 Hz, the monitored frequency for an overfrequency alarm must fall below 65 Hz
to reset the alarm.

Underfrequency Monitoring (Option U)

The monitoring of the frequency is carried out on two levels. The frequency measuring is monitored three-phase
if all voltages are greater than 15 % of the rated value (100 V or 400 V). This ensures quick and precise meas-
urement of the frequency. The frequency is still monitored correctly even if voltage is only applied to one phase.

Function "Frequency not within permissible limits"

The monitored frequency is not within the configured permissible limits for overfrequency. The alarm message
"Und.freq.1" or "Und.freq.2" will be displayed. This message can be suppressed with the discrete input
"Blocking of protective functions / remote acknowledgement".

this function are not displayed.

Underfrequency 1 Threshold underfrequency, level 1 40.00 to 80.00 Hz

f < 00.00Hz
Underfrequency (level 1) is defined by this parameter. If this limit is reached or
fallen below, the unit outputs the message "Und.freq.1". If a relay was assigned
to this function in the relay manager, that relay will be energized.

Underfrequency 1 Pickup delay, level 1 0.02 to 99.98 s

Underfrequency (level 2) is defined by this parameter. If this limit is reached or
fallen below, the unit outputs the message "Und.freq.2". If a relay was assigned
to this function in the relay manager, that relay will be energized.

Underfrequency 2 Pickup delay, level 2 0.02 to 99.98 s

least the period of time specified in this screen.

Underfrequency Hysteresis for the underfrequency monitoring, levels 1 + 2 0.01 to 9.99 Hz

Hysteres. 0.00Hz
In order to prevent system fluctuations from continually initiating underfrequency
alarms (both levels), a higher release point is defined here. If the control monitors
the frequency below the permissible limit, the frequency must rise above that
threshold and the frequency level defined here for the fault condition to be recog-
nized as no longer existing.
Example: If a 60 Hz system has an underfrequency limit of 50 Hz and a hysteresis
of 5 Hz, the monitored frequency for an overfrequency alarm must rise above
55 Hz to reset the alarm.

Vector / Phase Shift Monitoring (Option V)

A vector/phase shift is defined as the sudden variation of the voltage curve which may be caused by a major gen-
erator load change. The control unit measuring circuit detects the change in the cycle duration. This change in the
cycle duration is compared with a mean value calculated from previous measurements. The monitoring may be
carried out three-phased or one/three-phased. The threshold in degrees indicates the time difference between the
mean value and the instantaneous value, referring to the duration of a full cycle. The monitoring can be config-
ured in different ways. The vector/phase shift monitor can also be used as an additional method to decouple from
the mains. Vector/phase shift monitoring is only enabled after the monitored voltage exceeds 70% of the PT sec-
ondary rated voltage.

Function: "Cycle duration of the voltage not within permissible limits"

The voltage cycle duration is not within the configured vector/phase shift limits. The alarm message "Ph.
shift" appears. This message can be suppressed with the discrete input "Blocking of protective functions / re-
mote acknowledgement".

of this function are not displayed.

Phase jump monit Vector/phase shift monitoring one/three phase / 3 phase only
----------------
one/three phase: An alarm will be issued if the phase angle in any one phase ex-
ceeds the configured phase shift phase angle limit. Monitoring of
single-phase voltage is exceptionally sensitive and may lead to nui-
sance tripping if the configured phase angle is to low.
3 phase only: An alarm will be issued if the phase angle in all three phases exceeds
the configured phase shift phase angle limit within two waveforms.

NOTE
If the monitoring is configured as "3 phase only", only one of the two subsequent screens will be
displayed. If the monitoring is configured as "one/three-phase", both configuration screens will be
displayed.

An alarm will be issued if the phase angle in any all three phases exceeds the con-
figured phase shift phase angle limit. If the monitored voltage/frequency reaches
or exceeds the phase shift limit, the unit outputs the message "Ph. shift". If a
relay was assigned to this function in the relay manager, that relay will be ener-
gized.

df/dt (ROCOF) Monitoring (Option D)

Function: "Rate Of Change Of Frequency (ROCOF) is not within permissible limits"
Rate of Change Of Frequency (ROCOF) monitoring measures the stability of the frequency. The frequency of a
generator will vary due to changing loads and compensation of the fuel system. The rate of these frequency
changes due to the load variances is relatively high compared to those of a large network. The control unit calcu-
lates the unit of measure per unit of time. The df/dt is measured over 4 sine waves to ensure that it is differenti-
ated from a phase shift. This results in a response time of approximately 100ms. This message can be suppressed
with the discrete input "Blocking of protective functions / remote acknowledgement".

played.
NO ................The relays are configured with the factory default settings. The sub-
sequent screens are not displayed.

NOTE
All relay outputs are configured the same. The following is an example showing relays 1 through 3.
Depending on the model purchased, the unit may have up to 7 configurable relays. Option R enables
to use 5 additional relays

Example: Relay 1 to 3

Funct. relay 123 Function of the relays 1, 2 and 3 E/R

(R=releases) RRR
The individual relays may be configured as either E=Energizes (Normally Open
contacts) or R=Releases (Normally Closed contacts).

E ...................The relay is configured as normally open (N.O.) contacts. The relay

will energize only if the assigned monitoring function has tripped.
R ...................The relay is configured as normally closed (N.C.) contacts. The relay
is always energized and will only de-energize (release) if the as-
signed monitoring function has tripped.

NOTE Relay 1 is configured as R (release/N.C.) and cannot be modified.

NOTE
Units with Option YC do not enable to configure the function of relay 3. The synch-check function is
always assigned to relay 3 (or relay 8 for units with Option YC and Option R). Relay 3 (8) is fixed to
N.O. For reasons of redundancy, the synch-check function may also be assigned to relay 2 with the
following parameter starting with SW version 3.1450.

Each digit in this parameter is used to assign one relay to a protective function. Up
to four relay outputs may be assigned to a protective function. The control may be
configured as follows:
0.................... If the protective function is not assigned to a relay, a "0" must be
configured in the display. None of the relay outputs will energize/de-
energize when the corresponding protective function trips if all four
relay assignments are configured with a "0". A message for the pro-
tective function will still be visible in the unit display.
1/2/3 ............. Relay 1 (terminals 9/10), relay 2 (terminals 11/12/13), and/or relay 3
(terminals 14/15/16) are available for assignment to protective func-
tion on all units.
4/5/6/7/8 ....... Relay 4 (terminals 19/20/21), relay 5 (terminals 22/23/24), relay 6
(terminals 25/26/27), relay 7 (terminals 28/29/30), and/or relay 8
(terminals 31/32) are available for assignment to protective function
if the unit is equipped with Option R.
Example....... An MFR 11 with Option R has a protective function that us required
to output a signal to relays 2,4, and 7. That protective function relay
assignment should be configured as 2470. The sequence of the num-
bers has no significance in the functionality or operations.

A relay output may be assigned to more than one protective function. This will
cause the relay to issue a signal when any of the configured protective functions
trip. If a relay should only issue a signal when a specific protective function trips,
then the relay must not be assigned to any other protective function.

Commissioning

DANGER - HIGH VOLTAGE

When commissioning the control, please observe all safety rules that apply to the handling of live
equipment. Ensure that you know how to provide first aid in the event of an uncontrolled release of en-
ergy and that you know where the first aid kit and the nearest telephone are. Never touch any live com-
ponents of the system or on the back of the system:

LIFE THREATENING

CAUTION
Only a qualified technician may commission unit. The "EMERGENCY-STOP" function must be opera-
tional prior to commissioning of the system, and must not depend on the unit for its operation.

CAUTION
Prior to commissioning ensure that all measuring devices are connected in correct phase sequence.
The connect command for the unit circuit breaker must be disconnected at the unit circuit breaker. The
field rotation must be monitored for proper rotation. Any absence of or incorrect connection of voltage
measuring devices or other signals may lead to malfunctions and damage the unit, the engine, and/or
components connected to the unit!

Procedure
1. After wiring the unit and ensuring all voltage-measuring devices are phased correctly, apply the control
system voltage (i.e. 24 Vdc). The "Operation" LED will illuminate.

2. By simultaneously pressing the two push buttons "Digit↑" and "Cursor→", the configuration mode is ac-
cessed. After entering the access code number, the unit may be configured according to the application
requirements (see the chapter regarding the parameters).

3. After applying the measured variables, the unit will display the measured values. These values should be
confirmed with a calibrated measuring instrument.

4. Now, proceed as follows to change the code level:

until version 1.9xx:

---
Sealing function
Coding
ON
Enter: "ON" select and confirm using the "Select" button
---
Code input
Code no. 000
Code? ?????
Enter: Button "Select".
---
Incorrect input
Incorrect entry
[Next: Select]
Enter: Button "Select".
---
Break seal
Code no. 000
Break? NO
Enter: "YES" Select and confirm using "Select" button
---
Enter new code
Code no. 000
New code: ?????
Enter: Enter new code number and confirm using "Select" button

from version 2.0xx:

---
Enter code number 0 to 9999
Enter code
number 0000
On accessing the parameterization mode, a code number, which identifies the vari-
ous users, is first requested. The indicated number XXXX is a random number
(ZU) and is confirmed using the "Select" button. If the random number was con-
firmed without modification using "Select", the code level remains as it was. Two
four-digit code numbers (0000 to 9999) exist for changing the code level and set-
ting up new code words for the users. No assignment is required for the "third
party" user level, as the user does not usually receive access to the parameterization
level (protected via the code).

5. After the unit has been configured for the application, the configuration mode is exited by simultaneously
pressing the "Digit↑" and "Cursor→" buttons.

NOTE
Watchdog functions, which are not available, are transmitted with "01" (watchdog functions O.K.). Val-
ues which are not measured are transmitted with "0".

Description of the Data Format

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
NOTE
Certain addresses have two parts, the measured value and the exponent multiplier!

Voltage and current 0 to 9.999 without sign measured in [V, A], no exponent

Examples
UG12 = 103, exponent = 2
103 × 102 [V] = 1,030 [V] = 10.3 kV

IG1 = 80, exponent = -1

80 × 10-1 [A] = 8.0 [A] = 8.0 A

Bit Change at Tripping of a Watchdog Function

If one of the watchdog functions (protective alarms) responds, the corresponding bits (for example bit 15/14 =
overfrequency limit 2) will change from not tripped (= 0/1) to tripped (= 1/0).

Data format ......................... 16 bit binary value
Transmission rate................ 9,600 Baud.
Other baud rates on request. The records are transferred cyclically.

Procedure: When the transmitter is ready for data transmission, it notifies the receiver of this by switching its
control line RTS to "ON". The prerequisite of this is that no data are received (CTS = "OFF"). The receiver regis-
ters this status and indicates its readiness to receive by switching its RTS line to "ON". The transmitter can then
begin transmitting when it detects this "ON" status on its CTS line. As soon as the receiver withdraws its RTS
signal (RTS = "OFF"), the transmitter interrupts its transmission and waits until the receiver is ready to receive
again. The initialization conflict (both subscribers set the RTS line simultaneously) and timeout (one subscriber
waits in vain for a reply) must be taken into consideration.

Hardware.............................CAN bus
Transmission rate ................adjustable
Special characteristic...........Bt0 = 03, Bt1 = 1C

Every 200 ms a data telegram of 8 bytes is sent, which is structured as follows (all word variables are in the high
byte / low byte format):

Transmission Data

ID ........................................Base ID sending + CAN number

Byte 1 ..................................Multiplexer [1 to 9]
Byte 2 ..................................always 221
Byte 3/4 ...............................1. data word (note table, no. 1), multiplexed (MUX = 1, 1)
Byte 5/6 ...............................2. data word (note table, no. 2), multiplexed (MUX = 1, 2)

Byte 11/12 ...........................5. data word (note table, no. 5), multiplexed (MUX = 2, 2)
etc.

Control Data (Option SB)

ID ........................................Base ID control + CAN number

A data telegram of 7 Bytes is expected, which is structured as follows (all word vari-ables are in the high byte /
low byte format):

Byte 1 ..................................Multiplexer
Byte 2/3 ...............................1. data word (note table, no. 1), multiplexed (MUX = 1, 1)
Byte 4/5 ...............................2. data word (note table, no. 2), multiplexed (MUX = 1, 2)
Byte 6/7 ...............................3. data word (note table, no. 3), multiplexed (MUX = 1, 3)
etc.

Configuration Data (Option SF)

ID ........................................ID configure (default value: 831)

No ID’s can be assigned twice in the system. This applies for all devices coupled to the bus system. Likewise all
ID's set on the unit must be set to different values.

Procedure for base-ID transmission: All units available in the bus system are assigned to the same "Base ID
transmission". The types of information are grouped in this way.

Example: The base ID transmission = 800 is used with all units. The individual ID's are assigned to the various
unit numbers.

Unit number 1: ID = 801

Unit number 2: ID = 802
etc.

Procedure for base ID control: The same procedure applies for base-ID control. (Standard value 224)
