ABOUT THIS MANUAL

1 ABOUT THIS MANUAL

Be aware! This unit measures hazardous live currents and voltages!

Do not touch AC measuring inputs to avoid risk of (fatal) injury.

Installation and service to be carried out by authorized personnel only.

This manual describes the functionality of the standard off-the-shelf MEGA-GUARD E-series
Power Management System (PMS).

The MEGA-GUARD E-series PMS is an innovative automation system that takes minimum
engineering time and minimum different types of modules to design a complete power plant
for various bus and generation types.

The MEGA-GUARD E-series PMS allows for engineering a complete power plant with
identical off-the-shelf PMS-sets for each power/generation connection. It does so by
configuring the specific usage and function of each PMS-set via standard menu options that
fulfill most -if not all- commonly required functionality and grids. In instances where special
functionality and/or signals are required -beyond the off-the-shelf PMS design- the standard
PMS-sets can be easily expanded with minimal additional engineering.

The MEGA-GUARD E-series PMS can be used as a stand-alone system with a RS485 multi-
drop serial link to a 3 rd party Alarm & Monitoring System. It can also be integrated with other
MEGA-GUARD systems such as MEGA-GUARD Operator Workstation(s) for graphic
mimic plant representation or e.g. with MEGA-GUARD Alarm and Monitoring System.

PMS INTRODUCTION

2 PMS INTRODUCTION

The MEGA-GUARD Power Management System (PMS) is an advanced system that provides
the full automation of power plants with low or medium voltage switchboards.

The PMS is a modular system with one fully configurable PMS Controller for each
generation set or automatic bus-tie. With the standard pre-defined functionality -i.e. without
additional software engineering- there can be used maximum 9 PMS controllers to satisfy a
wide variety of grid configurations.

PMS functions include engine start/stop logic, sync check and auto synchronizing functions,
load sharing both active and re-active, frequency and voltage control, load block start
request/permissive handling and non preferential tripping.

The protection of the generator prime mover is to be fulfilled by an external independent

safety and protection system. Optionally this can be delivered with the PMS system.

2.1 System Overview

One PMS Controller consists of a PMS Control Panel including a PMS I/O-module. The PMS
Controllers for each generation set are interconnected via a redundant Ethernet bus.

Typical system lay-out for a PMS with 3 generators:

PMS INTRODUCTION

2.2 PMS Controller

The PMS Controller can operate as a stand-alone independent generator controller as well as a
fully integrated part of a complex and fully automated power management system. This level
of autonomy ensures the highest level of reliability and availability of each generation set.
Each PMS controller measures and displays up to 15 system variables. The standard PMS
Controller can also be configured as controller for an Automatic Bus-Tie (ABT) or an
automatic Shore connection circuit-breaker.

The PMS Controller -also referred to as PMS-set- consists of the following electronic
modules that are interconnected with a special I/O-cable:

PMS Operator Panel

PMS I/O module

2.2.1 PMS Operator Panel

The PMS Operator Panel is flush mounted in the front of the relevant switchboard section. It
provides a graphic monochrome display -for displaying the generator/bus variables- including
12 pushbuttons with LED indication lamps for operation of the generation set.

The main program for the generator control and power management is running in the PMS
Operator Panel executed by a powerful control processor. Two Ethernet ports maintain the
redundant communication with the other PMS Controllers e.g. for bus load calculations. The
control processor interfaces with the belonging PMS I/O board via a special I/O-cable with a
default length of 3 meter.

See paragraph 12.1 for the detailed hard-ware description of the PMS Operator Panel.

2.2.2 PMS I/O Module

The PMS I/O Module is enclosed in a rugged steel casing for DIN-rail mounting inside the
switchboard. It has screw terminals to connect the interface wiring e.g. to the engine and
generator and bus and circuit-breaker. The IO module is also equipped with a control
processor that performs autonomous control functions such as IO-scanning and time-critical
control functions such as synchronizing. The PMS I/O Module furthermore has synchronize
test modes that provides detailed LED test indications of the synchronizing bus-bar and
generator conditions such as voltage/frequency/angle okay and blackout conditions.

See paragraph 12.2 for the detailed hard-ware description of the PMS I/O module.

3.2 Alarm Display

The red ALARM lamp indicates an active alarm in this PMS Controller. The lamp is steady on
when there is a critical alarm that is blocking start and close commands. First the alarm(s)
must be accepted with the ACK button -and the ALARM lamp must go OFF -or change to
flashing- to enable these commands again. The lamp is flashing slowly when there is an active
alarm that is not blocking start and close commands (e.g. blackout) or flashing fast when
there is a system alarm.

Pushing the ALARM button shows the Alarm display. The Alarm Display returns to the
Operation Display by pushing the ALARM button again, or automatically when no scrolling
takes place for more then 30 seconds.

START-UP / INITIAL CONFIGURATION

4 START-UP / INITIAL CONFIGURATION

This chapter describes the usage of the menus and the PMS controller basic settings. These
basic settings could theoretically fulfill the configuration of a basic PMS due to the use of
relative (%) default settings for the functional parameterization. Refer to the next chapters for
the more detailed configuration of functions and options.

Observe basic safety rules before first power-up of the PMS Operator Panel(s) with
commissioning and e.g. service replacement, such as:

- Select Switchboard Local mode to prohibit any undesired controls until the PMS
controller is fully configured!
- Do not connect the Ethernet cables until after the controller number is set in the
boot loader menu (see 4.1) to avoid addressing conflicts and possible loss of
settings.

4.1 PMS Operator Panel first power-up (boot loader menu)

The first action with the panel first power-up must be the setting of the PMS controller
number. This setting is done in the boot loader menu that is accessed by pressing the ACK
button while connecting the 24Vdc power supply to the
panel. The controller is re-booted when the controller ACK. while Power-up
number is accepted (ACK) and stored in flash memory.

Example *1 - boot loader menu : Button functions for boot loader:

Boot loader menu
Scroll Up/Down to select Enter selected menu item

See example at grid type 4, par. 4.3

4.6 Power Measurement

The PMS-controller current measurement is configured with the ratio of the current
transformer (CT). For example, a current transformer with 1000A:1A step-down ratio is
configured with ratio setting of 1000.

For switchboards with rated voltages above 690VAC, external voltage transformers (VT)
must be used for measuring -and limiting- bus/generator voltages. For example, a VT that
reduces 6kV to 230V is configured with the ratio setting 26.1 (6000/230).

The PMS IO-board voltage measurement is optimized for measurement ranges [110~440Vac]
or [590~690Vac]. The IO-board input voltage -for example 230Vac- is set so that the IO-
board can automatically select the corresponding calibrated measurement range (in this
example: calibrated range [110~440Vac] is automatically selected).

Observe that the jumpers on the PMS IO-module are positioned according the
set voltage range (see 12.6)!

The PMS current measurement is optimized for measurements ranges up to [1A] or [5A]. The
IO-board input current -for example 2A- is set so that the IO-board can automatically select
the corresponding calibrated measurement range (in this example: calibrated range [5A] is
automatically selected).

Observe that the jumpers on the PMS IO-module are positioned according the
set current range (see 12.6)!

The PMS IO-board detects and alarms incorrect connections of the generator and/or bus.

Following alarms are enabled when the diesel engine is running and delayed with a fixed time
of 10 seconds:
GEN PHASE ERROR(271) is alarmed when the generator voltage (connections) L1, L2, L3
are falsely connected resulting in incorrect phase sequence.
GEN MISSING PHASE(272) is alarmed when the generator voltage (connections) L1 or L2 or
L3 are not connected or failed otherwise.
GEN FREQUENCY FAIL(273) is alarmed when the generator frequency drops below 70% of
nominal frequency.

Following alarms are enabled when a bus voltage (>20%) is measured and delayed with a
fixed time of 10 seconds:
BUS PHASE ERROR(274) is alarmed when the bus voltage (connections) L1, L2, L3 are
falsely connected resulting in incorrect phase sequence.
BUS MISSING PHASE(275) is alarmed when the bus voltage (connections) L1 or L2 or L3
are not connected or failed otherwise.
BUS FREQUENCY FAIL(276) is alarmed when the bus frequency drops below 70% of
nominal frequency.

The IO-board Led indications VOLTAGE GENERATOR and VOLTAGE BUSBAR show the

energized (on) -or not energized (off)- generator/bus status.

7.4 Engine Start

The engine *1 [D/G] or [E/G] can be started with a manual or automatic start engine command.

START
The manual start engine command is given with the PMS Operator Panel
RUN pushbutton when in AUTO or MANUAL mode or -optional- from PMS mimic. The
pushbutton lamp is flashing while starting/energizing; on when energized.

Causes that can give an automatic start engine command:

Blackout (see 8.3)
High Load start (see 8.4)
Standby start options (see 8.7)
Bus abnormal alarm (see 5.1)
Consumer block request (see 8.8)

The start command is accepted -and the pre-lubrication output activated- when the engine is
ready to start and set in remote control and there is no external safety shutdown or pre-alarm.
The start output is activated when the pre-lubricating finished. The start output is de-activated
-and the start is successful- when the engine achieves the running status. The start attempt
failed when the engine does not achieve the running status within the re-start delay that is
started at the end of the start pulse. In AUTO the start output will then be activated again and
this will be repeated until the number of start attempts is completed or until the engine
achieves the running status. In MANUAL there will only be performed one start attempt.

Described functionality and settings allow the PMS-set to directly operate an engine start
solenoid valve. If the engine is equipped with its own local control system the number of start
attempts must

7.5 Engine Stop

The engine [D/G] or [E/G] can be stopped with a manual or automatic stop engine command.

STOP
The manual stop engine command is given with the PMS Operator Panel pushbutton
when in AUTO or MANUAL mode or -optional- from PMS mimic.
The pushbutton lamp is flashing while stopping (e.g. during cool down); on when
engine is stopped.

Causes -except external- that can give an automatic stop engine command:

Engine idle run time (cool down) finished

The stop command is accepted -and the stop output activated- when the engine is set in
remote control and when the generator circuit-breaker is open. A stop command during
normal operation can either be an operator command e.g. from the stop pushbutton or -in
AUTO- an automatic stop command after engine cooling down. The stop output is activated
for the duration of the stop pulse time.

7.6 Close Circuit-Breaker (including auto-synchronize)

The generator Circuit-Breaker is closed following a manual or automatic close breaker

command after first the gen-set has been automatically synchronized.

The manual close breaker command is given with the PMS Operator Panel
CLOSE pushbutton when in AUTO or MANUAL mode or -optional- from PMS mimic or
external CB close request input signal.
The lamp is flashing while synchronizing; on when the circuit-breaker is closed.

Causes that can give an automatic close breaker command:

Following a standby start request (see 8.4 )

The close command (pushbutton or automatic) is accepted when the gen-set is running and
energized. If the bus is dead, the circuit-breaker will be directly closed. If the bus is energized,
this gen-set [D/G] or [E/G] will first be synchronized with the energized bus before closing the
circuit-breaker.

Each PMS-set has a dedicated SYNCHRONIZER that is integrated on the PMS I/O module.
The synchronizer controls the frequency of the gen-set to the frequency of the energized bus
before allowing the circuit-breaker to be closed when the bus/generator phase angle and the
voltage/frequency deviation is within the specified dead band. The synchronizer controls the
gen-set with raise/lower speed signals.

The synchronizer can be put in a test mode that allows visual verification of the synchronizer
conditions on the board LEDs without actually closing the circuit-circuit breaker.

7.8 Open Circuit-Breaker

The generator Circuit-Breaker is opened following a manual or automatic open breaker

command.

The manual open breaker command is given with the PMS Operator Panel
OPEN pushbutton when in AUTO or MANUAL mode or -optional- from PMS mimic or
external CB open request input signal. In AUTO the open breaker command is
blocked if disconnection would cause a blackout. The lamp is flashing while
offloading (AUTO only); on when the circuit-breaker is opened.

Causes that can give an automatic open breaker command:

Generator is being offloaded (see 8.5)
Generator protections (see 5.3)
External trip signals
Offload failure (optional)

In MANUAL mode the command will open the circuit-breaker regardless of the generator or
bus load therewith potentially causing a plant blackout when not operated with care. In
AUTO mode the generator is disconnected in controlled manner i.e. the circuit-breaker will
only be opened after first the generator is offloaded below the low load limit.

anyway or will remain closed for the operator to take the appropriate actions. This alarm must
first be reset before this gen-set can be started or loaded again.

CB OPEN FAILURE(215) is alarmed when the breaker is not actually opened after the open
command. In AUTO mode the gen-set is now controlled back to the average plant load to
avoid a reverse power situation. This alarm must first be reset before this gen-set can be
offloaded again (and open the circuit-breaker again).

7.9 Trip Circuit-Breaker

The circuit-breaker can be tripped -i.e. opened without offloading- by the generator
protections (see 5.3) and by the following optional CB trip command input channels (only
active when the relevant input channel has been configured):

CB trip command : trip CB e.g. from external protection system

CB trip manual command : trip CB when in MANUAL e.g. from SWBD pushbutton
CB trip all command : trip all CB e.g. at manual connection of shore supply*1
CB trip all auto command : trip all CB that are in AUTO *1

The circuit-breaker can also be tripped by external devices outside the PMS such as automatic
circuit breaker (ACB) or short-circuit protection device (S/C).

ACB ABNORMAL TRIPPED(227) is alarmed when CB was tripped by external ACB device
or when CB was opened by unknown cause.

CB TRIP EXT. COMMAND(228) is alarmed when any of the command inputs (14~17)
is
activated and meets the relevant conditions.

SHORT-CIRCUIT DEVICE TRIPPED CB (229) is alarmed when CB was tripped by external

short-circuit device. No new generators will be automatically started when there are two -or
more- of these alarms present on the bus.

Any CB trip(ped) command results in the automatic tripping of all non-preferential groups
and -if option enabled (see 8.7)- results in the start of the next standby generator.

7.10 Frequency Adjustment

[D/G] or [E/G]
The gen-set frequency is adjusted with the PMS operator panel INC/DEC
pushbuttons.
The increase/decrease frequency command is given with the PMS Operator Panel
INC.
pushbuttons when in MANUAL mode, or automatically in AUTO mode.
The lamps are on while the corresponding button is pushed or while the
DEC. corresponding engine increase/decrease speed signals are automatically operated.

Causes that can give automatic increase/decrease commands:

Synchronizing prior to closing the circuit-breaker
Offloading prior to opening the circuit-breaker
Load sharing (see 8.1)

In MANUAL mode the pushbuttons will increase/decrease the gen-set speed and therewith
correspondingly increase/decrease the frequency and consequently increase/decrease the
(active) load.

In AUTO mode the pushbuttons can be used to adjust taking or shedding extra load on this
gen-set from the otherwise balanced shared load (see 8.1).

8 PLANT OPERATION

Plant automatic functions described in this chapter are only applicable for the PMS-sets that
are set in AUTO mode and which do not have unaccepted alarms blocking automatic
functions.

8.1 Load Sharing

In AUTO mode the PMS-sets perform balanced load sharing by default. In this mode all
interconnected*1 gen-sets will be equally loaded as percentage of their capacity. Each PMS-
set load setpoint is calculated as the average load of all gen-set that are connected to the grid
and that are set in AUTO. Standard the PMS-set performs speed (frequency) control of the
gen-set [D/G] or [E/G] to perform active load sharing (i.e. percentage of capacity in kW).

2. LOAD DEVIATION DELAY SEC

LOAD TOO HIGH DEVIATION (216) is alarmed -only in balanced load sharing mode- when
the load deviates more then (+/-) the maximum load deviation for longer then the delay time.

In AUTO mode the operator can set/adjust a base load setpoint on a specific gen-set by using
the INC/DEC pushbuttons. This results in unbalanced load sharing mode until the base load
setpoint is reset. The base load setpoint -when set- is shown on the main operation display.

The base load is automatically reset when the bus load drops below the reset unbalanced
mode load level or after the preset time or when the gen-set is disconnected, stopped or put in
MANUAL. The operator can manually reset the unbalanced load setpoint by pushing the
INC+DEC pushbuttons simultaneous. Gen-sets will not be automatically stopped by low load
condition (see 8.5) during unbalanced load sharing mode.

8.2 Start/Stop Sequence

Each gen-set -with the standby start enabled (see 4.7)- is part of the standby start sequence
which means that the gen-set can be automatically started by a standby start request.

Each gen-set is assigned a sequence number that represents the order in which the gen-sets are
automatically connected by standby start requests. In a split bus operation the standby start
sequence is determined for each bus section.

1st. The gen-set that is ready to connect*1 with the lowest sequence number on the bus or
STBY on the split bus section will be first connected and is indicated with the 1ST STBY
pushbutton lamp on the operator panel.
2nd.
STBY Next gen-set that will be connected is indicated with the 2ND STBY pushbutton lamp.

The start sequence of each gen-set can be set by operating the 1ST STBY or 2ND STBY
pushbuttons. The gen-set where the 1ST STBY pushbutton is pressed becomes the next (first: if
no gen-sets are running) in the standby sequence. It does so by exchanging his sequence
number with the gen-set that otherwise would have been started next. The same functionality
-for altering the second gen-set in the start sequence- applies when operating the 2ND STBY
pushbutton. In split bus operation these buttons only affect the start sequence of the own bus
section. The start sequence can not be changed while any generator is starting/synchronizing
on the own bus.

The stop sequence is the reversed start sequence: the connected gen-set with the highest
sequence number will be first offloaded and disconnected when allowed by the low load
demand. The stop sequence of the connected gen-sets can be changed by pressing the button
1ST STBY which -in this connected case- makes this the first-to-stop. Note that this also alters
the start sequence of the other connected gen-sets.

*1 Ready to connect: gen-set healthy/without alarms and set in AUTO (and not yet connected)

All gen-sets disconnected from this bus section.

When the bus section of the 1ST standby gen-set has a blackout, this generator will be started
and connected. A blackout recovery delay can be set e.g. to start the emergency generator
with little delay therewith first allowing recovery via the main gen-sets and prevent isolation
of the emergency bus.

8.8 Heavy Consumer Blocks

When there is not sufficient load available or generators running and preconfigured heavy
consumers are planned to be switched on the bus, the next standby gen-set(s) will be started
and connected before the specific heavy consumer is allowed to be connected to the bus.

The consumer activates the request input after which the spinning reserve and the number of
connected generators are checked against the configured requirements of the consumer. When
more generation is required, next standby generator(s) are started. The consumer block accept
output is activated when the requirements of the consumer block are fulfilled and the request
input is still active and after a set delay. The requests are processed in sequence from lowest
number to highest number if more then one heavy consumer is requested at the same time.
The accept output is reset when the number of connected gen-sets becomes too low or when
the request input is deactivated. The low load auto stop function is disabled while there is a
heavy consumer request active.

Each PMS-set -except when used as ABT- has the possibility for configuring up to 4 heavy
consumers on any bus (see 4.3) with each their power requirements and requirement for
number of connected generators. The consumer blocks furthermore require that the
appropriate request input signals (see 6.2) and accept output signals (see 6.3) are configured.

8.9 Non-preferential Groups

When the bus is close to overloading, groups of non-preferential consumers can be tripped to
prevent an actual bus overload.

The high load limit and delay can be configured at which condition each non-preferential
group will be tripped. This allows groups to be tripped in predefined order. The non-
preferential group(s) will be tripped without any delay when there is a circuit-breaker tripped
on the corresponding bus. The non-preferential group(s) on the board will be tripped without
any delay when the programmable group trip input is activated. The trip output remains active
as long as the trip condition remains active with a minimum time of 5 seconds.

Each PMS-set -except when used as ABT- has the possibility for configuring up to 4 non-
preferential groups on any bus (see 4.3) with each their high load trip condition and delay.
The non-preferential groups furthermore require that the appropriate trip output signals (see
6.3) are configured. As a response to any non-preferential trip the next standby generator can
be started, if this option is enabled (see 8.7).

MODBUS SLAVE INTERFACE

11 MODBUS SLAVE INTERFACE

A RS485 multi-drop serial port is provided on each PMS Operator Panel that outputs the
alarms and monitoring values of each gen-set via a MODBUS slave protocol and accepts
basic PMS commands.

The RS485 ports of all PMS Operator panels are connected parallel (see 12.5) as a RS485
multi-drop link to a host computer that operates as the MODBUS MASTER. The PMS
controllers are accessible by their MODBUS slave number (see 4.2). The host computer must
provide a galvanic isolation of its RS485 serial input port.

The Mega-Guard PMS system uses the Cyclic Redundancy Check (CRC) as the error check
for each message.

Detailed explanation of the MODBUS protocol can be found in the Gould Modicon Modbus
Protocol Reference Guide, Nov.'83, Gould Inc., Andover. Praxis Automation Technology can
supply you with a copy of the relevant pages.

11.1 MODBUS Functions

Supported MODBUS functions are:

READ READ FORCE

HOLDING INPUT SINGLE
REGISTERS REGISTERS COIL
MODBUS 03 04 05
DIGINP (undefined) (undefined) set input
status
ANAINP input value input value ERROR

Function 03/04
Analog channels described in this chapter can be requested by MODBUS function
nalog
channel.
Function 05
Specific Digital input channels (commands) described in this chapter can be forced
on/off by MODBUS function '05'.

Function 03 and 04: The query message specifies the starting register and quantity of registers
to be read. registers are addressed starting at zero: register 1-16 are addressed as 0-15
Function 05: The query specifies the coil reference to be forced. coils are addressed starting at
zero: coil 1 is addressed as 0.

Structures are sent according Motorola (MSB LSB or Big Endian) processor set.
The MSB and LSB are (two's complement) signed integers (PMS maximum range = -9999 till
9999).

Examples:
9999 (dec.) = Byte 1: 27 (hex.) ; Byte 2: 0F (hex.).
1 (dec.) = Byte 1: 00 (hex.) ; Byte 2: 01 (hex.).
0 (dec.) = Byte 1: 00 (hex.) ; Byte 2: 00 (hex.).
-1 (dec.) = Byte 1: FF (hex.) ; Byte 2: FE (hex.).
-9999 (dec.) = Byte 1: D8 (hex.); Byte 2: F1 (hex.).

analog
values (2 bytes data).

Each PMS controller is addressed with its slave number (see 4.2).
The controller alarms and relevant statuses are requested with function 03 and send as
packed digital data.
The controller analog values are requested with function 04*1. The values are multiplied by a
scale factor for a better resolution since decimal points are not available in the used integer
range. To get the original decimal formatting the Modbus-master must scale the received data
with the scaling factor as is given in the Modbus list.

11.2 Exception Codes

Standard MODBUS error messages (exception responses) are returned on any illegal request.

Illegal Function (Code 01)

On any function request other than 01, 02, 03, 04, 05 ,06, 15 and 16; the code 01h will
be returned to indicate an illegal function code received.

Illegal Data Address (Code 02)

On function request 05 when addressing an analog in- or output channel.
On function request 05 when addressing any channel which is not set-up for
MODBUS.
When the (start) address lies outside the Mega-Guard-PMS MODBUS point range.
When the number of points requested is zero, or leads to an address outside the
MODBUS point range (function 04: 01001 till 24068).
On function request 04 when requesting more than 125 points (= 125 Mega-Guard-
PMS values)

Note: MODBUS points within the PMS range which refer to undefined -or spare- addresses
are still valid addresses and will return an undefined value.

Illegal Data Value (Code 03)

On function 05 with a value other than 0000h or FF00h.

Failure in Associated Device (Code 04)

When the CRC-check of the query fails.

The PMS controller makes no difference between function requests 03 or 04.

11.3 Response Time

The MODBUS query is processed at the end of each I/O scan cycle. The worst case delay is
one cycle time plus overhead of in total 95 milliseconds. The typical delay is half the cycle
time (ca. 50 milliseconds).

11.4 RS485 Port Hardware

The RS485 ports of all PMS Operator panels are connected in multi-drop configuration (see
12.5) to a host computer that operates as the Modbus-master. The host computer must provide
a galvanic isolation of its RS485 serial input port.
