 Introduction

1 INTRODUCTION
This document details the installation and operation requirements of the DSEG8680 module and is
part of the DSEGenset® range of products.

The manual forms part of the product and should be kept for the entire life of the product. If the
product is passed or supplied to another party, ensure that this document is passed to them for
reference purposes.
This is not a controlled document. DSE do not automatically inform on updates. Any future updates of
this document are included on the DSE website at www.deepseaelectronics.com

The DSEG8680 series is designed to provide differing levels of functionality across a common
platform. This allows the generator OEM greater flexibility in the choice of controller to use for a
specific application.

Synchronising and Load Sharing features are included within the controller, along with the necessary
protections for such a system.

The user also has the facility to view the system operating parameters via the text LCD display.

The DSE8680 is an intelligent control module designed to control a generator bus-tie breaker. The
control module features technology that automatically manages the synchronising and check-sync
across the breaker using the DSE Advanced Multi-Set communications (AMSC) link when opening
and closing the bus-tie breaker.

The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:

• Text based LCD display

• True RMS Voltage
• Current and Power monitoring
• USB, RS485 and Ethernet Communications
• Fully configurable inputs for use as alarms or a range of different functions.
• Synchronising and load sharing with load demand start/stop (when operating as a loadswitch)
• Integral PLC to help provide customisation where required
• Data Logging

The DSE Configuration Suite PC Software allows alteration of selected operational sequences,
timers, alarms, and operational sequences. Additionally, the module’s integral front panel
configuration editor allows adjustment of this information.

Module access and critical operational sequences and timers for use by qualified engineers, can be
protected by a security code. Selected parameters can be changed from the module’s front panel
using the Running Editor.

The module is housed in a robust plastic case suitable for panel mounting. Connections to the module
are via locking plug and sockets.

VA RATING OF THE CTS

NOTE: Details for 4 mm² cables are shown for reference only. The connectors on the DSE
modules are only suitable for cables up to 2.5 mm².

The VA burden of the module on the CTs is 0.5 VA. However, depending upon the type and length of
cabling between the CTs and the module, CTs with a greater VA rating than the module are required.

The distance between the CTs and the

measuring module should be
estimated and cross-referenced
against the chart opposite to find the
VA burden of the cable itself.

Example:
If 1.5 mm² cable is used and the
distance from the CT to the measuring
module is 20 m, then the burden of the
cable alone is approximately 15 VA.
As the burden of the DSE controller is
.5 VA, then a CT with a rating of at
least 15 VA + 0.5 VA = 15.5 VA must

be used. 0.5 VA, then a CT with a rating of at least 15 VA + 0.5 VA = 15.5 VA must be used. If 2.5
mm² cables are used over the same distance of 20 m, then the burden of the cable on the CT is
approximately 7 VA. CT’s required in this instance is at least 7.5 VA (7 + 0.5).

CT POLARITY

NOTE: Take care to ensure correct polarity of the CT primary as shown above. If in doubt,
check with the CT supplier.

Take care to ensure the correct polarity of the CTs otherwise the power flow direction across the bus
tie breaker will be incorrect and will make power sharing and ramping malfunction. Take note that
paper stick-on labels on CTs that show the orientation are often incorrectly placed on the CT. It is
more reliable to use the labelling in the case moulding as an indicator to orientation (if available).

Labelled as Labelled as
p1, k or K p2, l or L

To Generator To Load

Polarity of CT Primary

CT PHASING

Take particular care that the CTs are connected to the correct phases. For instance, ensure that the
CT on phase 1 is connected to the terminal on the DSE module intended for connection to the CT for
phase 1.

CT CLASS

Ensure the correct CT type is chosen. For instance, if the DSE module is providing over current
protection, ensure the CT can measure the overload level required to protect against, and at the
accuracy level required.

For instance, this may mean fitting a protection class CT to maintain high accuracy while the CT is
measuring overload currents.

Conversely, if the DSE module is using the CT for instrumentation only (current protection is disabled
or not fitted to the controller), then measurement class CTs can be used. Again, bear in mind the
accuracy required. The DSE module is accurate to better than 1% of the full-scale current reading. To
maintain this accuracy, fit a Class 0.5 or Class 1 CT.

Check with the CT manufacturer for further advice on selecting CTs.

NOTE: DSE stock 2 m (6.5 feet) USB type A to type B cable, DSE Part Number: 016-125.
Alternatively, they are purchased from any PC or IT store.

NOTE: The DC supply must be connected to the module for configuration by PC.

NOTE: For further details of module configuration, refer to DSE Publication: 057-326
DSEG8680 Configuration Suite PC Software Manual.

The USB port is provided to give a simple means of connection between a PC and the controller.
Using the DSE Configuration Suite Software, the operator is then able to control the module, starting
or stopping the engine, selecting operating modes, etc.

Additionally, the various operating parameters (such as coolant temperature, oil pressure, etc.) of the
engine are available to be viewed or changed.

To connect a module to a PC by USB, the following items are required:

DSEG8680 Controller

DSE Configuration Suite PC Software

(Available from www.deepseaelectronics.com).

USB cable Type A to Type B.

(This is the same cable as often used between a PC and a USB
printer)

RS485 PORT

NOTE: When the RS485 Port Usage is configured to “PLC Comms”, all other modules’
Port Usage must be configured to “Gencomm”. This allows the module configured as “PLC
Comms” to act as a master and read from the module(s) configured to “Gencomm”.
For details on how to configure the PLC Editor to read via its RS485, refer to DSE Publication:
057-314 Advanced PLC Software Manual which is found on our website:
www.deepseaelectronics.com

NOTE: For a single module to PC connection and distances up to 5 m (16 feet) the USB
connection method is more suitable and provides for a lower cost alternative to RS485 (which
is more suited to longer distance connections).

The RS485 port on the controller support the Modbus RTU protocol and is for connection to a single
Modbus master device only.

The DSE Modbus register table for the controller is available upon request from the DSE Technical
Support Department.

RS485 is used for point-to-point cable connection of more than one device (maximum 32 devices)
and allows for connection to PCs, PLCs, and Building Management Systems (to name just a few
devices).

One advantage of the RS485 interface is the large distance specification (1.2 km when using Belden
9841 (or equivalent) cable. This allows for a large distance between the module and a PC running the
DSE Configuration Suite software. The operator is then able to control the module, starting or
stopping the engine, selecting operating modes, etc.

The various operating parameters (such as coolant temperature, oil pressure, etc.) of the remote
engine are viewed or changed.

Many PCs are not fitted with an internal RS485 serial port. DSE DOES NOT recommend the use of
USB to RS485 convertors but can recommend PC add-ons to provide the computer with an RS485
port.

The DSEG8680 has one RS485 ports which are configurable using the Configuration Suite Software.
An example of configuring the RS485 connection using the DSE Configuration Suite Software is
shown below:

ETHERNET PORT

NOTE: For further details of module configuration, refer to DSE Publication: 057-326
DSEG8680 Configuration Suite Software Manual.

NOTE: For a single module to PC connection and distances up to 5 m (16 feet) the USB
connection method is more suitable and provides for a lower cost alternative to Ethernet
(which is more suited to longer distance connections).

NOTE: DSE stock 2 m (6.5 feet) Ethernet Cable, DSE Part Number: 016-137. Alternatively,
they can be purchased from any PC or IT store.

Ethernet is used for point-to-point cable connection of more than one device and allows for
connection to PCs, PLCs, Building Management Systems and SNMP Managers (to name just a few
devices) or to other DSE modules using the PLC Editor.

One advantage of the Ethernet interface is the ability to interface into an existing LAN (Local Area
Network) connection for remote connection via an internet connection. This allows for a large distance
between the module and a PC running the DSE Configuration Suite software or any external device.
The operator is then able to control the module, starting or stopping the engine, selecting operating
modes, etc through various means.

4.10.4.1 MODBUS TCP

The Ethernet port on the controller supports the Modbus TCP protocol and is for connection for up to
five Modbus master devices. The various operating parameters (such as coolant temperature, oil
pressure, etc.) of the remote engine are viewed or changed.

The DSE Modbus register table for the controller is available upon request from the DSE Technical
Support Department.

4.10.4.2 ETHERNET PORT USED FOR PLC COMMUNICATION

NOTE: For details on how to configure the PLC Editor to read through the TCP/IP, refer to
DSE Publication: 057-314 Advanced PLC Software Manual which is found on our website:
www.deepseaelectronics.com

The DSE module can communicate with other DSE modules using the Ethernet Port, this is
configured from the PLC Editor to allow it read specific GenComm registers from other modules over
the TCP/IP to perform certain tasks in the PLC.
When the DSE module is configured to communicate with the other modules via the TCP/IP it
becomes a Modbus TCP Master, hence care must be taken on the slave TCP modules not to exceed
their total supported five Modbus TCP masters.

4.10.4.7 FIREWALL CONFIGURATION FOR INTERNET ACCESS

NOTE: For further details of module configuration, refer to DSE Publication: 057-326
DSEG8680 Configuration Suite Software Manual.

As modem/routers differ enormously in their configuration, it is not possible for DSE to give a
complete guide to their use with the module. However, it is possible to give a description of the
requirements in generic terms. For details of how to achieve the connection to your modem/router you
are referred to the supplier of your modem/router equipment.

The module makes its data available over Modbus TCP or SNMP V2c and as such communicates
over the Ethernet using a Port configured via the DSE Configuration Suite software.

You must configure your modem/router to allow inbound traffic on this port. For more information you
are referred to your WAN interface device (modem/router) manufacturer.

It is also important to note that if the port assigned is already in use on the LAN, the module cannot be
used, and another port must be used.

Outgoing Firewall Rule

As the module makes its user interface available to standard web browsers, all communication uses
the chosen port. It is usual for a firewall to make the same port outgoing open for communication.

Incoming Traffic (Virtual Server)

Network Address and Port Translation (NAPT) allows a single device, such as the modem/router
gateway, to act as an agent between the Internet (or "public external network") and a local (or
"internal private") network. This means that only a single, unique IP address is required to represent
an entire group of computers.

For our application, this means that the WAN IP address of the modem/router is the IP address we
need to access the site from an external (internet) location.

When the requests reach the modem/router, we want this passed to a ‘virtual server’ for handling, in
our case this is the module.

Result: Traffic arriving from the WAN (internet) on port xxx is automatically sent to IP address set
within the configuration software on the LAN for handling.

NOTE: The Modbus Master can be another DSE module communicating through its PLC. For further
details see section 4.10.3 entitled RS485 Ports in this document.

Serial Port

Baud 115200
Slave ID 10
RS485
The modules operate as a Modbus RTU slave device.
In a Modbus system, there is only one Master, typically a PLC, HMI system, PC SCADA system, or
another DSE module using its PLC Comms.

This master requests for information from the Modbus slave (The module) and may (in control
systems) also send request to change operating modes etc. Unless the Master makes a request, the
slave is ‘quiet’ on the data link.

The factory settings are for the module to communicate at 115200 baud, Modbus slave address 10.

‘Master inactivity timeout’ should be set to at least twice the value of the system scan time. For
example, if a Modbus master PLC requests data from the module once per second, the timeout
should be set to at least 2 seconds.

The DSE Modbus document containing register mappings inside the DSE module is available upon
request from support@deepseaelectronics.com. Email the request along with the serial number of the
DSE module to ensure the correct information is sent.

7.1 BUS TIE CONFIGURATION
There are two possible configurations for the Bus tie controller which can enabled on the Application
page in the Configuration Software.

BUS TIE

The Bus Tie Configuration enables control of two bus segments on the left (Segment 1) and right side
(Segment 2).

LOAD SWITCHING

The Bus Tie controller can be used for load switching by selecting Load Switching in the Configuration
Suite.

Load

The load must be on Right side as shown above.

Page 93 of 128 057-327 ISSUE: 4

 Operation

7.2 BUS TIE OPERATION

The DSEG8680 has two AMSC Ports, one for each side of the bus. The DSEG8680 only closes the
generator bus-tie when it is told to via button presses, digital input (Close Bus Tie) or on receipt of
command over Modbus.
When the DSEG8680 bus tie breaker is open, the left-hand bus does not communicate to the right-
hand bus, and they are seen as two separate systems.

057-327 ISSUE: 1 Page 94 of 128

 Operation

All generators are started using the Remote Start input and when the generators become available,
they close onto a dead bus.
As the DSEG8680 breaker is open, the two sides are separate systems. This means a DSE8600 on
either side attains their own token to know it is safe to close onto the dead bus. Both sides of the
bus-tie are working independently with the load demand scheme.
[JR7][IR8]

Page 95 of 128 057-327 ISSUE: 4

 Operation

Before the DSEG8680 is requested to close its breaker it must attain a token that is different to the
tokens of the DSEG8600s.Once it has this token it will gain control of one side of the generator bus
(depending on configuration) and synchronizes it to the other. Once in sync the DSEG8680 closes its
breaker and releases its token and then both sides of the bus are considered as one. If the Close Bus
Input is removed, the DSEG8680 opens its bus breaker without requiring a token Once the breaker is
open, both sides become independent again and each attain their own token.

057-327 ISSUE: 1 Page 96 of 128

 Operation

7.3 SEGMENT GROUPS

1. When two or more segments are connected by the closure of one or more breakers, they
form a Segment Group.

The Left Segment and Right Segment numbers are used to identify Bus segments.
This is illustrated in the example below.

Example

Hint: If
the Bus Tie Controller is
closed then Bus Segment 2 (Left)
and Bus Segment 3 (Right)
become a Segment Group.

2. Segment Groups are dynamic, being created, destroyed, and altered as the system operates.
3. A Load Share Scheme operates within a single Segment Group.
4. A Load Demand Scheme operates within a single Segment Group.
5. A Segment Group can have one and only one Master Token, though it may have none if no
module requires one.
6. A Master Token controls one and only one Segment Group.
7. A module is considered to be in a Segment Group that contains a segment that the module is
directly connected to, i.e., it is broadcasting that segment number in its Configuration
Broadcast message.
8. All modules must continually perform the task of building a map of the segment groups. This
is done using the segment numbers in the Configuration Broadcast message from each
module and the state of the bus breakers in the Bus Tie and Mains Controllers. A closed
breaker in these modules joins two segment groups to form one larger one.

WARNING!: The Left Bus Segment number and Right Bus Segment number cannot be the
same! This is critical for safe control!

 Operation

7.4 BREAKER CLOSING ON DEAD BUSSES

If one or both sides of the breaker are dead (depending on configuration), and a request to close is
active, then the bus tie will attempt to close the breaker without synchronising or ramping.

The controller will first request a control token and once received the bus tie will close the breaker. If
the “Bus Closed” auxiliary input fails to indicate that the breaker is closed, the bus tie will open the
breaker again and raise an alarm.

The configuration options to allow the bus breaker to close onto a dead bus are:

Disabled: Breaker closing is only enabled if both busses are live.

• Left Bus to Right Bus: Breaker closing is only enabled if the left bus is live (with the right bus
dead or live).
• Right Bus to Left Bus: Breaker closing is only enabled if the right bus is live (with the left bus
dead or live).
• Either: Breaker closing is only enabled if one or both busses are live.
• Always: Breaker closing is always enabled.

7.5 BREAKER CLOSING ON LIVE BUSSES

If both sides of the breaker are live, the module will decide on the bus to control as described below.

• If module is in manual mode, then the breaker button that is pressed determines which bus is
controlled. If the left button is pressed then generation on the left bus will be controlled to
synchronise the busses. Similarly, if the right button is pressed then generation on the right
bus is controlled.
• If the breaker is being closed by a GenComm simulated button press message then the
decision is the same as above based on whether the left or tight breaker button is being
simulated.
• If the breaker is being closed by a GenComm control key then the message determines which
bus is controlled: Close Left or Close Right.
• If the module is in auto mode and there is a digital input for “Close Bus Tie” and there is
another digital input for “Control Right Side of Bus Tie” then this second signal determines
which side of the bus tie is controlled when the close signal becomes active; if it is inactive
then the left side is controlled, and if its active the right side is controlled.
• If the module is in auto mode and there is a digital input for “Close Bus Tie” and there is no
digital input for “Control Right Side of Bus Tie” then a setting in the config determines which
side of the bus tie is controlled.

If a suitable bus to control can be determined, the bus tie will negotiate on that bus for the master
token, to allow it exclusive generator control.
If the controller fails to get the token in a configured time, an “ nable to Obtain Master Token” alarm is
raised.
Two output sources are available to indicate when the master token has been obtained for each side
of the breaker. These can be used to drive the user-defined LEDs in order to indicate when a bus is
being controlled for ramping or synchronising.
Once the master token is obtained, the tie will synchronise the busses and close the breaker. If the
bus tie cannot control a suitable bus for synchronisation, a check-sync will be performed instead to
determine if the breaker can be closed.
If a “Bus Closed” auxiliary input fails to indicate that the breaker is closed, the bus tie will open the
breaker again and raise an alarm.
Failure to synchronise/check-sync in a configurable time will result in a “failed to Sync” alarm.

057-327 ISSUE: 1 Page 98 of 128

 Operation

7.6 RAMPING ON
At the end of the synchronisation phase, the G8680 will close the bus tie. If there is generation on the
busses on both sides of the breaker then the generators will almost certainly be no longer sharing
power equally. The bus tie must now equalise the power sharing if it can.
Before closing the breaker, the bus tie will record the overall power levels from the two bus segments,
information which is available from the AMSC. Once the bus tie breaker is closed the bus tie will
switch the generators on both sides to constant power mode. It will then set new power levels (via the
AMSC) for the generators for them to share the load equally (as a percentage of their capability).
Once this sharing has been achieved, the bus tie will signal the SEGMENTS_COMBINED flag to
indicate that the two power segments are now a single group and will release the master control
token. This will allow another module to take control of the combined segment to apply the configured
power scheme.

7.7 BREAKER OPENING WITH DEAD BUS

If the bus is dead when a breaker open request is received, the bus tie will attempt to open the
breaker
If a “Bus Closed” auxiliary input fails to indicate that the breaker is open, the bus tie will close the
breaker again and raise an alarm.
Failure to open the breaker in a configurable time will result in a “Bus Failed to Open” alarm.
Once the breaker is confirmed to be open, the “SEGMENTS_COMBINED” flag will be cleared to
signal to the rest of the AMSC network that the busses have now been separated into two segments.

7.8 BREAKER OPENING WITH LIVE BUS

If the bus is live when a breaker open request is received, the bus tie will attempt to ramp one of the
busses to reduce the current flow across the breaker to a minimal amount, which can be configured.
As described above the bus tie will determine which bus to control based on the configured options
and optionally the “Control Right Bus” input.
If a suitable bus to control can be determined, the bus tie will negotiate on that bus for the master
token, to allow it exclusive generator control.
If the controller fails to get the token in a configured time, an “ nable to Obtain Master Token” alarm is
raised.

7.9 RAMPING OFF

Once the master control token is obtained, the bus tie can attempt to ramp off. This process differs
depending on whether the breaker is fitted with a CT.
• If a CT is fitted, the bus tie will ramp the bus being controlled to minimise the measured power
through the breaker. Once this minimum is reached (as determined by a minimum power
level available through SCADA) the bus tie can open the breaker. It will then separate the two
segments (via the AMSC) and release the master control token.
• If there are no CTs fitted that can measure the power through the breaker, the bus tie relies
on a configurable power level provided by the user. The bus tie will ramp the bus that it is
controlling until the AMSC reports that the power level of the controlled bus matches the pre-
set value. At this point the bus tie will open the breaker.

Segment 1 Segment 2
Available LED Available LED

There are two breaker control buttons, designated the left and right bus buttons. They are only active
when the module is operating in manual mode.
Their function differs depending on the state of the two busses and the state of the bus tie breaker
itself.
• If the bus tie is closed, pressing either breaker button causes an open request to be made.
• If the bus tie is open, and one or more busses are dead, then a close request is made, and
the breaker will be closed based on the configuration options in effect (which may prevent
closure under various combinations of live and dead busses).
• If the bus tie is open, and both busses are live, then an attempt will be made to synchronise
the busses before closing the bus tie. If the left button was pressed, then the left bus will be
controlled, and synchronised with the right. If this is not possible (for example if there is a
mains supply connected to the left bus or there are no controllable generators on that bus)
then an alarm will be raised, and the breaker will not close. Similarly, if the right button is
pressed, the right bus will be controlled, and synchronised with the left.
The breaker control buttons can also be simulated via GenComm. In that case the button
operation is the same.

BUS TIE LED STATUS INDICATIONS

The bus and breaker states are indicated on the front of the module by three green LEDs as follows:

• Left Bus LED: This is illuminated to show that the bus is available.
• Right Bus LED: This is illuminated to show that the bus is available.
• Breaker LED: This shows the state of the breaker auxiliary input.
Note that a bus is available if it has voltage and frequency within the minimum and maximum bus
availability settings and can thus be synchronised. If the LED is extinguished, it is outside these
ranges.

NOTE: If a bus available LED is extinguished this does not indicate a dead bus.

 Operation

BREAKER CONTROL

When the breaker is closed using the breaker button (or simulated buttons) the synchronisation
direction (left to right or right to left) is determined by which button is pressed. However, when using a
digital input or GenComm control key to close the breaker, the direction is not specified. Instead, two
user-configurable options and 1 digital input are used to determine the bus to control when
synchronising.

• Synchronise left bus to right bus option.

• Synchronise right bus to left bus option.
• “Control Right Bus” digital input.
When “Control Right Bus” digital input is configured, the other options become unavailable, and the
controlled bus is determined by whether the signal is active (control right bus) or inactive (control left
bus). If that bus cannot be controlled, then an alarm will be raised, and the synchronisation aborted.
When “Control Right bus” digital input is not configured, the bus to be controlled Is selected by the
user options to select left bus or right bus.

BUS TIE CLOSE REQUEST

A bus tie close request can occur in one of four cases:

• Breaker is open and a front panel breaker control button is pressed, “Bus Close Inhibit” digital
input is not active, and module is in manual mode.
• GenComm Control Key “Close Bus” is received and “Bus Close Inhibit” digital input is not
active.
• “Close Bus” digital input becomes active, “Bus Close Inhibit” digital input is not active, and
module sis in auto mode.
• “Bus Close Inhibit” digital input becomes inactive and “Close bus” digital input is active.

BUS TIE OPEN REQUEST

A bus tie open request can occur in one of four cases:

• Breaker is closed and a front panel breaker control button is pressed, and module is in
manual mode.
• GenComm Control Key “Open Bus” is received.
• “Close Bus” digital input becomes inactive, and the module is in auto mode.
• “Bus Close Inhibit” digital input becomes active. This will cause the breaker to open
immediately without ramping off

8.2 LED INDICATORS

The LED indicators display non-critical and often status conditions. They do not appear on the LCD
display of the module as a text message in the Status, Event Log or Alarms pages. However, an
output or LED indicator can be configured to draw the operator’s attention to an event.

Example:

• Input configured for

indication.

• The LCD text does not

appear on the module
display but can be added in
the configuration to remind
the system designer what
the input is used for.

• As the input is configured to

Indication there is no alarm
generated.

• LED Indicator 1 illuminates

when Digital Input A is
active.

• The Insert Card Text allows

the system designer to print
an insert card detailing the
LED function.

• Example showing operation

of the LED.

8.3 WARNING ALARMS

Warnings are non-critical alarm conditions and do not affect the operation of the engine system, they
serve to draw the operator’s attention to an undesirable condition.

Example:

In the event of an alarm the LCD jumps to the alarms page and scroll through all active alarms.

By default, warning alarms are self-resetting when the fault condition is removed. However, enabling
All Warnings Are Latched causes warning alarms to latch until reset manually. This is enabled using
the DSE Configuration Suite in conjunction with a compatible PC.

 Fault Finding

10 COMMISSIONING
10.1 BASIC CHECKS
Before the system is started, it is recommended that the following checks are made:

The unit is adequately cooled and all the wiring to the module is of a standard and rating compatible
with the system. Check all mechanical parts are fitted correctly and that all electrical connections
(including earths) are sound.

Check all mechanical parts are fitted correctly and that all electrical connections (including earths) are
good. The unit DC supply is fused and connected to the battery and that it is of the correct polarity.

Check the operation of the AMSC Link. Use the DSE Configuration Suite to check this in the SCADA |
BUS | AMSC Link page. Verify the number of Set On The Bus is equal to that of the number of
DSEG86xx modules.

Set the modules internal clock/calendar to ensure correct operation of the scheduler and event
logging functions. For details of this procedure, see section entitled Front Panel Configuration

If, despite repeated checking of the connections between the controller and the customer’s system,
satisfactory operation cannot be achieved, then the customer is requested to the DSE Technical
Support Department

10.2 METERING

CAUTION!: Failure to perform the Metering steps results in incorrect power factor and kW
calculations leading to problems with kW and kvar load sharing if not corrected.

WARNING!: Steps must be taken to ensure that when a CT is open circuit, the
system/generator is in a safe state to work around.

10.2.1.1 CTS ON THE RIGHT PHASE

Check to ensure that the CTs on L1, L2 & L3 are connected to their respective connection on the DSE
module.

This is tested by loading the bus with a purely resistive load (around 10% of the main’s size) across
the three phases. If the CTs are wired correctly to the DSE module, it displays unity power factor (1.0
pf) across all three phases. If unity power factor is not displayed the CTs have been wired to the
wrong phases on the DSE module.

10.2.1.2 CTS IN THE RIGHT DIRECTION

NOTE: Checking that the CTs are on the right phase MUST be completed prior to checking
if the CTs are in the correct direction. CTs on the wrong phase also cause negative kWs.

Check to ensure that the CTs on L1, L2 & L3 have been mounted for the correct orientation for current
flow and that the S1 and S2 have not been swapped over.

This is tested by loading the bus with a purely resistive load (around 10% of the main’s size) across
the three phases. If the CTs’ S1 and S2 are wired to correctly to the DSE module, it displays positive
kW. If negative kWs is displayed the CTs’ S1 and S2 have been swapped around.

 Commissioning

10.3 COMMUNICATIONS

CAUTION!: Failure to perform the Communications steps results in the controllers being
unable to communicate to the other DSE controllers leading to problems during load sharing.

NOTE: For further details of module configuration, refer to DSE Publication: 057-326
DSEG8680 Configuration Suite Software Manual.

Check to ensure that all the modules are connected are communicating correctly on the AMSC link
and Redundant AMSC (if used).

This is tested by connecting the DSE module to a PC with the DSE Configuration Suite PC Software
installed and going to the SCADA | Bus | AMSC Link section. The information shown in this section
changes dynamically depending on whether the AMSC Link or Redundant AMSC Link is in use. The
number of Sets On The Bus must be the same as the number of DSEG8600 (Multi Set)s on the link.
The number of Mains Controllers On The Bus must be the same as the combined number of
DSEG8660s in Mains Controller mode.

If these numbers do not match up there is a fault on the active link. To find the module with the fault,
connect into each module individually until the Sets On The Bus or Mains Controllers On The Bus
reports 1.

If these numbers do match up, then the link which is currently in use is working correctly. To test the
other link, remove the active link connection from any module. All the modules should then alarm with
the same number link failure (AMSC 1 Link Failure or AMSC 2 Link Failure). If all the modules do not
have the same number link failure, then at some point the AMSC and CAN connections have been
crossed. If all the modules do have the same number link failure, the communication is automatically

10.4 SEGMENTATION OF THE BUS

The G Series allows the system to act locally and allows each isolated section to work either
independently or as part of combined system. For this to be safe it is vitally important that the
segmentation is set up correctly.

When a Bus Sensing Failed alarm is activated, it is important that each segment is isolated and that
breakers (G8660 bus breakers and G8680 ties) are opened.

Example

Example: If
a Bus Sensing Failed
Alarm is activated then opening
the Bus Tie Controller isolates Bus
Segment 2 and Bus Segment 3.
[JR9][IR10]

Example: Powering up a generator

will test to see if any module has a
Bus Sensing Failed Alarm active.

To check each segment is live, a generator needs to be powered up to ensure that there are no
modules with the Bus Sensing Failed alarm that are active. This ensures that there are no modules on
a different segment that have this segment ID. See section 3.8.5.2 in document 057-324 entitled
DSEG8660 Configuration Suite PC Software Manual for further information.

The user must then disconnect each module’s bus sensing on this segment and check that the alarm
occurs, this confirms that the modules on this segment are correctly configured.

WARNING!: The Bus Segment number and Load Segment number cannot be the same!
This is critical for safe control!

11.2 INSTRUMENTS

Symptom Possible Remedy

Check:
• That the CT primary, CT secondary and VT ratio settings
are correct for the application.
• That the CTs are wired correctly with regards to the
direction of current flow (p1,p2 and s1,s2) and additionally
ensure that CTs are connected to the correct phase (errors
occur if CT1 is connected to phase 2).
Inaccurate measurements on • Remember to consider the power factor:
controller display (kW = kV A x Power Factor)
• The DSE8xxx MKII modules are true RMS measuring so
gives more accurate display when compared with an
‘averaging’ meter such as an analogue panel meter or
some lower specified digital multimeter.
• Accuracy of the controller is better than 1% of full scale.
Voltage full scale is 415 V AC ph-N so accuracy is ±4.15 V
(1% of 415 V).
