Introduction
2 INTRODUCTION
This document details the installation and operation requirements of the DSE8610 Series modules,
part of the DSEPower® 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. You will not be automatically informed of updates. Any future
updates of this document will be included on the DSE website at www.deepseaplc.com
The DSE8600 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.
The DSE8600 series module has been designed to allow the operator to start and stop the generator,
and if required, transfer the load to the generator either manually (via fascia mounted push-buttons) or
automatically.
Synchronsing 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 LCD display.
The DSE8600 module monitors the engine, indicating the operational status and fault conditions,
automatically shutting down the engine and giving a true first up fault condition of an engine failure by
a COMMON AUDIBLE ALARM. The LCD display indicates the fault.
The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:
• Text based LCD display (supporting multiple languages).
• True RMS Voltage, Current and Power monitoring.
• Engine parameter monitoring.
• Fully configurable inputs for use as alarms or a range of different functions.
• Engine ECU interface to electronic engines.
• Direct connection to governor / AVR for synchronising and load sharing
• R.O.C.O.F. and Vector shift for detection of mains failure when in parallel with the mains supply.
Using a PC and the Configuration Suite software allows alteration of selected operational sequences,
timers and alarms.
Additionally, the module’s integral fascia configuration editor allows adjustment of a subset of this
information.
A robust plastic case designed for front panel mounting houses the module. Connections are via
locking plug and sockets.

3.2 POWER SUPPLY REQUIREMENTS
Minimum supply voltage 8V continuous
Cranking dropouts Able to survive 0V for 50mS providing the supply was at least 10V
before the dropout and recovers to 5V afterwards.

3.4.1 VA RATING OF THE CTS
The VA burden of the DSE8610 module on the CTs is 0.5VA. However depending upon the type and
length of cabling between the CTs and the DSE8610 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.
If the CTs are fitted within the
alternator top box, the star point
(common) of the CTs should be
connected to system ground (earth) as
close as possible to the CTs. This
minimises the length of cable used to
connect the CTs to the DSE module.
Example.
If 1.5mm² cable is used and the
distance from the CT to the measuring
module is 20m, then the burden of the
cable alone is approximately 15VA. As
the burden of the DSE controller is
0.5VA, then a CT with a rating of at
least 15+0.5V = 15.5VA must be used.
If 2.5mm² cables are used over the
same distance of 20m, then the
burden of the cable on the CT is
approximately 7VA. CT’s required in
this instance is at least 7.5VA (7+0.5).
0.5VA (0.02Ω current shunts)
NOTE: Details for 4mm² cables are shown for reference only. The connectors on the DSE
modules are only suitable for cables up to 2.5mm².
NOTE: CTs with 5A secondary windings are recommended with DSE modules. 1A CTs can
be used if necessary however, the resolution of the readings is 5 times better when using 5A
CTs.

Specifications
3.4.2 CT POLARITY
Take care to ensure the correct polarity of the CTs. Incorrect CT orientation will lead to negative kW
readings when the set is supplying power. 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).
To test orientation, run the generator in island mode (not in parallel with any other supply) and load the
generator to around 10% of the set rating. Ensure the DSE module shows positive kW for all three
individual phase readings.

POLARITY OF CT PRIMARY
NOTE: Take care to ensure correct polarity of the CT primary as shown above. If in doubt,
check with the CT supplier.
TO LOAD SWITCH DEVICE
3.4.3 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.
Additionally ensure that the voltage sensing for phase 1 is actually connected to generator phase 1.
Incorrect connection of the phases as described above will result in incorrect power factor (pf)
measurements, which in turn results in incorrect kW measurements.
One way to check for this is to make use of a single-phase load. Place the load on each phase in turn,
run the generator and ensure the kW value appears in the correct phase. For instance if the load is
connected to phase 3, ensure the kW figure appears in phase 3 display and not in the display for
phase 1 or 2.
3.4.4 CT CLASS
Ensure the correct CT type is chosen. For instance if the DSE module is providing overcurrent
protection, ensure the CT is capable of measuring the overload level you wish to protect against, and
at the accuracy level you require.
For instance, this may mean fitting a protection class CT (P10 type) 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 you require. The DSE module is accurate to better than 1% of the full-scale current reading.
To maintain this accuracy you should fit Class 0.5 or Class 1 CTs.
You should check with your CT manufacturer for further advice on selecting your CTs

. The charge fail input is actually a combined input and output. Whenever the generator is required to
run, the terminal provides excitation current to the charge alternator field winding.
When the charge alternator is correctly charging the battery, the voltage of the terminal is close to the
plant battery supply voltage. In a failed charge situation, the voltage of this terminal is pulled down to a
low voltage. It is this drop in voltage that triggers the charge failure alarm. The level at which this
operates and whether this triggers a warning or shutdown alarm is configurable using the DSE Config
Suite Software.

3.8 COMMUNICATION PORT USAGE
3.8.1 CAN INTERFACE
Modules are fitted with the CAN interface as standard and are capable of
receiving engine data from engine CAN controllers compliant with the
CAN standard.
CAN enabled engine controllers monitor the engine’s operating
parameters such as engine speed, oil pressure, engine temperature
(among others) in order to closely monitor and control the engine. The industry standard
communications interface (CAN) transports data gathered by the engine controller interface. This
allows generator controllers such as the DSE8600 series to access these engine parameters with no
physical connection to the sensor device.
NOTE: For further details for connections to CAN enabled engines and the functions
available with each engine type, refer to the manual Electronic Engines and DSE Wiring. Part

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 (1.2km when using Belden
9841 (or equivalent) cable. This allows for a large distance between the DSE8600 series module and
a PC running the DSE Configuration Suite software. The operator is then able to control the module,
starting or stopping the generator, selecting operating modes, etc.
The various operating parameters (such as output volts, oil pressure, etc.) of the remote generator
can be viewed or changed.

3.8.6 MSC
The MSC (Multi System control) is used to communicate with other DSE modules in a system.
The MSC is used for point-to-point cable connection of more than one device (maximum 32
Generator controller and another 8 Mains / Bus tie devices giving a maximum of 40 units)
The maximum distance is 250M using Belden 9841, 120ohm impedance screened twisted pair cable.
This can be extended using DSE124 Can Bus Extender
NOTE: Version 86xx V 5.0 included a change to the MSC link protocol which is not
compatible with lower versions until the lower versions have been upgraded to version 5.0
(This can be done using “Update Firmware” in Configuration Suite Software) .
NOTE: At version 5.1+ The MSC communication changed to enable 86xx ranges to
communicate with 55xx and 75xx range of modules.
When using 55xx or 75xx with 86xx the MSC capability lowers to that of the 55xx/ 75xx series.
i.e. Max units that can be used together in the case of 55xx,75xx would be 16 generators on the
MSC link at anyone time, not the 32 Gen sets that the DSE86xx is specified.

Firewall configuration for internet access
As modem/routers differ enormously in their configuration, it is not possible for DSE to give a complete
guide to their use with the DSE8610. 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 DSE8610 makes its data available over Modbus TCP and as such communicates over the
Ethernet using a Port configured via the DSE config 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 (setting from software “Modbus Port Number”) is
already in use on the LAN, the DSE8610 cannot be used and another port must be used .
Outgoing Firewall rule
As the DSE8610 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 DSE8610 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 requests reaches the modem/router, we want this passed to a ‘virtual server’ for handling, in our
case this is the DSE8610 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 (DSE8610) for handling.
NOTE: Refer to DSE8600 series Configuration Suite Manual (DSE part 057-119) for further
details on configuring, monitoring and control.

‘typical wiring diagram’ elsewhere in this document.
NOTE : DSE8600 series does not support the 2510/2520 display modules.
3.8.13 DSENET® USED FOR MODBUS ENGINE CONNECTION
As DSENet® utilises an RS485 hardware interface, this port can be configured for connection to
Cummins Modbus engines (Engines fitted with Cummins GCS).
This leaves the RS485 interface free for connection to remote monitoring equipment (i.e. Building
Management System, PLC or PC RS485 port).
While this is a very useful feature in some applications, the obvious drawback is that the DSENet®
interface is no longer available for connection to expansion devices.

3.9.1 ADDING AN EXTERNAL SOUNDER TO THE APPLICATION
Should an external alarm or indicator be required, this can be achieved by using the DSE
Configuration Suite PC software to configure an auxiliary output for “Audible Alarm”, and by
configuring an auxiliary input for “Alarm Mute” (if required).
The audible alarm output activates and de-activates at the same time as the module’s internal
sounder. The Alarm mute input and internal alarm mute button activate ‘in parallel’ with each other.
Either signal will mute both the internal sounder and audible alarm output.
Example of configuration to achieve external sounder with external alarm mute button:

NOTE: It is VERY important that terminal 15 (sensor common) is soundly connected to an
earth point on the ENGINE BLOCK, not within the control panel, and must be a sound electrical
connection to the sensor bodies. This connection MUST NOT be used to provide an earth

5.3.6 RS232 SERIAL PORT
This section is included to give information about the RS232 serial port and external modem (if
connected).
The items displayed on this page will change depending upon configuration of the module. You are
referred to your system supplier for further details.
NOTE: Factory Default settings are for the RS232 port to be enabled with no modem
connected, operating at 19200 baud, modbus slave address 10.
Example 1 – Module connected to an RS232 telephone modem.
When the DSE8610 series module is power up, it will send ‘initialisation strings’ to the connected
modem. It is important therefore that the modem is already powered, or is powered up at the same
time as the DSE86xx series module. At regular intervals after power up, the modem is reset, and
reinitialised, to ensure the modem does not ‘hang up’.
If the DSE8610 series module does not correctly communicate with the modem, “Modem initialising’
appears on the Serial Port instrument screen as shown overleaf.
If the module is set for “incoming calls” or for “incoming and outgoing calls”, then if the modem is
dialled, it will answer after two rings (using the factory setting ‘initialisation strings)’. Once the call is
established, all data is passed from the dialling PC and the DSE8610 series module.
If the module is set for “outgoing calls” or for “incoming and outgoing calls”, then the module will dial
out whenever an alarm is generated. Note that not all alarms will generate a dial out; this is dependant
upon module configuration of the event log. Any item configured to appear in the event log will cause a
dial out.

Description Of Controls
In case of communication failure between the modem and DSE8600 series module, the modem is
automatically reset and initialisation is attempted once more:
3)
In the case of a module that is unable to communicate with the modem, the display will
continuously cycle between ‘Modem Reset’ and ‘Modem Initialising’ as the module resets the
modem and attempts to communicate with it again, this will continue until correct
communication is established with the modem.
In this instance, you should check connections and verify the modem operation.
Example 2 – Module connected to a modem.
Example 3 – Modem status of a GSM modem
Currently connected GSM
operator and signal strength.
Many GSM modems are fitted with a status LED to show operator cell status and ringing indicator.
These can be a useful troubleshooting tool.
In the case of GSM connection problems, try calling the DATA number of the SIMCARD with an
ordinary telephone. There should be two rings, followed by the modem answering the call and then
‘squealing’. If this does not happen, you should check all modem connections and double check with
the SIM provider that it is a DATA SIM and can operate as a data modem. DATA is NOT the same as
FAX or GPRS and is often called Circuit Switched Data (CSD) by the SIM provider.
NOTE: In the case of GSM modems, it is important that a DATA ENABLED SIM is used.
This is often a different number than the ‘voice number’ and is often called Circuit Switched
Data (CSD) by the SIM provider.
If the GSM modem is not purchased from DSE, ensure that it has been correctly set to operate at
9600 baud. You may need to install a terminal program on your PC and consult your modem supplier
to do this. GSM modems purchased from DSE are already configured to work with the DSE86xx
series module.

5.3.7 RS485 SERIAL PORT
This section is included to give information about the currently selected serial port and external
modem (if connected).
The items displayed on this page will change depending upon configuration of the module. You are
referred to your system supplier for further details.
NOTE: Factory Default settings are for the RS485 port to operating at 19200 baud, modbus
slave address 10.
Module RS485 port configured for connection to a modbus master.
DSE86xx series modules operate as a modbus RTU slave
device.
In a modbus system, there can be only one Master, typically a
PLC, HMI system or PC SCADA system.
This master requests for information from the modbus slave
(DSE86xx series 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 19200 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 DSE86xx modbus slave once per second,
the timeout should be set to at least 2 seconds.
The DSE Modbus Gencomm document containing register mappings inside the DSE module is
available upon request from support@deepseaplc.com. Email your request along with the serial
number of your DSE module to ensure the correct information is sent to you.
Typical requests (using Pseudo code)

5.4 VIEWING THE EVENT LOG
The module maintains a log of past alarms and/or selected status changes.
The log size has been increased in the module over past module updates and is always subject to
change. At the time of writing, the 86xx series log is capable of storing the last 250 log entries.
Under default factory settings, the event log only includes shutdown and electrical trip alarms
logged (The event log does not contain Warning alarms); however, this is configurable by the
system designer using the DSE Configuration Suite software.
Example showing the
possible configuration of the
DSE8600 series event log
(DSE Configuration Suite

This also shows the factory
settings of the module (Only
shutdown alarms and the
mains status are logged).
Once the log is full, any subsequent shutdown alarms will overwrite the oldest entry in the log.
Hence, the log will always contain the most recent shutdown alarms.
The module logs the alarm, along with the date and time of the event (or engine running hours if
configured to do so).

5.6 CONTROLS
Stop / Reset
This button places the module into its Stop/Reset mode. This will clear any alarm
conditions for which the triggering criteria have been removed. If the engine is running
and the module is in Stop mode, the module will automatically instruct the changeover
device to unload the generator (‘Close Generator’ becomes inactive (if used)). The fuel
supply de-energises and the engine comes to a standstill. Should a remote start signal
be present while operating in this mode, a remote start will not occur.
Manual
This mode allows manual control of the generator functions. Once in Manual mode the
module will respond to the start button, start the engine, and run off load. If the
engine is running off-load in the Manual mode and a remote start signal becomes
present, the module will automatically instruct the changeover device to place the
generator on load (‘Close Generator’ becomes active (if used)). Upon removal of the
remote start signal, the generator remains on load until either selection of the
‘STOP/RESET’ or ‘AUTO’ modes.
For further details, please see the more detailed description of ‘Manual operation’
elsewhere in this manual.
Auto
This button places the module into its ‘Automatic’ mode. This mode allows the module
to control the function of the generator automatically. The module will monitor the
remote start input and mains supply status and once a start request is made, the set will
be automatically started and placed on load.
Upon removal of the starting signal, the module will automatically transfer the load from
the generator and shut the set down observing the stop delay timer and cooling timer as
necessary. The module will then await the next start event. For further details, please
see the more detailed description of ‘Auto operation’ elsewhere in this manual.
Start
This button is only active in STOP/RESET or MANUAL mode.
Pressing this button in manual or test mode will start the engine and run off load
(manual) or on load (test).
Pressing this button in STOP/RESET mode will turn on the CAN engine ECU (when
correctly configured and fitted to a compatible engine ECU)
Mute / Lamp Test
This button silences the audible alarm if it is sounding and illuminates all of the LEDs as
a lamp test feature/
When correctly configured and fitted to a compatible engine ECU, pressing this button in
STOP/RESET mode after pressing the START button (to power the ECU) will
cancel any “passive” alarms on the engine ECU.

Operation
6 OPERATION
The following description details the sequences followed by a module containing the standard ‘factory
configuration’.
Remember that if you have purchased a completed generator set or control panel from your supplier,
the module’s configuration will probably have been changed by them to suit their particular
requirements.
Always refer to your configuration source for the exact sequences and timers observed by any
particular module in the field.
6.1 ALTERNATIVE CONFIGURATIONS
Depending upon the configuration of your system by the generator supplier, the system may have
selectable configurations (for example to select between 50Hz and 60Hz running). If this has been
enabled your generator supplier will advise how this selection can be made (usually by externally
operated selector switch or by selecting the required configuration file in the DSE8600 series front
panel configuration editor).
75
Operation
6.2 DUMMY LOAD / LOAD SHEDDING CONTROL
This feature may be enabled by the system designer to ensure the loading on the generator is kept to
a nominal amount. If the load is low, ‘dummy loads’ (typically static load banks) can be introduced to
ensure the engine is not too lightly loaded. Conversely, as the load increases towards the maximum
rating of the set, non-essential loads can be shed to prevent overload of the generator.
6.2.1 DUMMY LOAD CONTROL
The dummy load control feature (if enabled) allows for a maximum of five dummy load steps.
When the set is first started, all configured Dummy Load Control outputs are de-energised.
Once the generator is placed onto load, the generator loading is monitored by the Dummy Load
Control scheme.
If the generator loading falls below the Dummy Load Control Trip setting (kW), the Dummy Load
Control Trip Delay is displayed on the module display. If the generator loading remains at this low level
for the duration of the timer, the first Dummy Load Control output is energised. This is used to
energise external circuits to switch in (for instance) a
static load bank.
The generator loading has now been increased by the first dummy load. Again, the generator loading
is monitored.
This continues until all configured Dummy Load Control outputs are energised.
Should the generator loading rise above the Dummy Load Return level, the Dummy Load Return
Delay begins.
If the loading remains at these levels after the completion of the timer, the ‘highest’ active Dummy
Load Control output is de-energised. This continues until all Dummy Load Control outputs have been
de-energised.
Example screen shot of Dummy Load Control setup in the DSE Configuration Suite
76
Operation
6.2.2 LOAD SHEDDING CONTROL
The Load Shedding Control feature (if enabled) allows for a maximum of five load-shedding steps.
When the generator is about to take load, the configured number of Load Shedding Control Outputs at
Startup will energise. This configurable setting allows (for instance) certain loads to be removed from
the generator prior to the set’s load switch being closed. This can be used to ensure the initial loading
of the set is kept to a minimum, below the Load Acceptance specification of the generating set.
The generator is then placed on load. The Load Shedding Control scheme begins.
When the load reaches the Load Shedding Trip level, the Trip Delay timer will start. If the generator
loading is still high when the timer expires, the first Load shedding Control output will energise. When
the load has been above the trip level for the duration of the timer the ‘next’ Load shedding Control
output will energise and so on until all Load Shedding Control outputs are energised.
If at any time the load falls back below the Load Shedding Return level, the Return Time will start. If
the load remains below the return level when the timer has expired the ‘highest’ Load Shedding
Control output that has been energised will be de-energised. This process will continue until all outputs
have been de-energised.
When the set enters a stopping sequence for any reason the Load Shedding control’ outputs will deenergise at the same time as the generator load switch is signalled to open.

6.4 STOP MODE
78
Operation
STOP mode is activated by pressing the button.
NOTE: Enable Cool Down in Stop Mode option has been added to version 6.0
In STOP mode, the module will immediately remove the generator from load (if necessary) before
stopping the engine if it is already running.
• If Cool Down in Stop Mode not enabled, no cooling run is provided for this operation. Where a
cooling run is required, switch to MANUAL mode and open the breaker manually. Allow the
set to cool off load, before pressing the STOP button to stop the engine.
• If Cool Down in Stop Mode enabled, cooling run is provided for this operation. The set will run
off load for the amount of time configured in Load/Stopping Timers, Cooling Time before the
set is stopped.
If the engine does not stop when requested, the FAIL TO STOP alarm is activated (subject to the
setting of the Fail to Stop timer). To detect the engine at rest the following must occur:
• Engine speed is zero as detected by the Magnetic Pickup or CANbus ECU (depending upon
module variant).
• Generator frequency must be zero.
• Oil pressure switch must be closed to indicate low oil pressure (MPU version only)
When the engine has stopped, it is possible to send configuration files to the module from DSE
Configuration Suite PC software and to enter the Front Panel Editor to change parameters.
Any latched alarms that have been cleared will be reset when STOP mode is entered.
The engine will not be started when in STOP mode. If remote start signals are given, the input is
ignored until AUTO mode is entered.
When configured to do so, when left in STOP mode for five minutes with no presses of the fascia
buttons, the module enters low power mode. To ‘wake’ the module, press the button or any other
fascia control button.

Operation
6.4.1 ECU OVERRIDE
NOTE: Depending upon system design, the ECU may be powered or unpowered when the
module is in STOP mode. ECU override is only applicable if the ECU is unpowered when in
STOP mode.
When the ECU is powered down (as is normal when in STOP mode), it is not possible to read the
diagnostic trouble codes or instrumentation. Additionally, it is not possible to use the engine
manufacturers’ configuration tools.
As the ECU is usually unpowered when the engine is not running, it must be turned on manually as
follows:
• Select STOP mode on the DSE controller.
• Press and hold the START button to power the ECU. As the controller is in STOP mode,
the engine will not be started.
• Continue to hold the start button for as long as you need the ECU to be powered.
• The ECU will remain powered until a few seconds after the START button is released.
This is also useful if the engine manufacturer’s tools need to be connected to the engine, for instance
to configure the engine as the ECU needs to be powered up to perform this operation.

• Activation of the inbuilt exercise scheduler.
• Instruction from external remote telemetry devices using the RS232 or RS485 interface.
6.5.2 STARTING SEQUENCE
To allow for ‘false’ start requests such as mains brownouts, the start delay timer begins. There are
individual start delay timers for each of the different start request types.
Should all start requests be removed during the start delay timer, the unit will return to a stand-by
state.
If a start request is still present at the end of the start delay timer, the fuel relay is energised and the
engine will be cranked.
NOTE: If the unit has been configured for CAN, compatible ECU’s will receive the start
command via CAN.
If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the crank
rest duration after which the next start attempt begins. Should this sequence continue beyond the set
number of attempts, the start sequence will be terminated and the display shows Fail to Start.
The starter motor is disengaged when the engine fires. Speed detection is factory configured to be
derived from the main alternator output frequency, but can additionally be measured from a Magnetic
Pickup mounted on the flywheel (Selected by PC using the 8600 series configuration software).
Additionally, rising oil pressure or charge alternator voltage can be used to disconnect the starter
motor (but cannot detect underspeed or overspeed).
NOTE: If the unit has been configured for CAN, speed sensing is via CAN.
After the starter motor has disengaged, the Safety On timer activates, allowing Oil Pressure, High
Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise
without triggering the fault.
81
Operation
6.5.3 ENGINE RUNNING
Once the engine is running, the Warm Up timer, if selected, begins, allowing the engine to stabilise
before accepting the load.
If the common bus is measured to be ‘dead bus’, the load breaker is closed.
If the bus is measured to be ‘live bus’, synchronising takes place before the breaker is closed.
NOTE: The load transfer signal remains inactive until the Oil Pressure has risen. This
prevents excessive wear on the engine.
As the load increases and decreases, the DSE86xx series module (may (depending upon
configuration) add dummy loads or remove non-essential loads. This is configured as part of the Load
Shedding and Dummy Load control settings in the DSE Configuration Suite Software.
See section entitled Dummy Load / Load Shedding elsewhere in this document for further details.
Additionally, when configured as part of a multiset package, the generator may be automatically
started and stopped depending upon load requirements.
If in doubt, consult your system supplier for details of how your particular system has been configured.
If all start requests are removed, the stopping sequence will begin.
6.5.4 STOPPING SEQUENCE
The return delay timer operates to ensure that the starting request has been permanently removed
and is not just a short-term removal. Should another start request be made during the cooling down
period, the set will return on load.
If there are no starting requests at the end of the return delay timer, the load is ramped off the
generator being the breaker is opened and the cooling timer is initiated.
The cooling timer allows the set to run off load and cool sufficiently before being stopped. This is
particularly important where turbo chargers are fitted to the engine.
If the set is called to return to load before the cooling timer has expired, the Engine Running operation
is again followed.
After the cooling timer has expired, the set is stopped.

this action.
Manual mode allows the operator to start and stop the set manually, and if required change the state
of the load switching devices.
6.6.1 WAITING IN MANUAL MODE
When in manual mode, the set will not start automatically.
To begin the starting sequence, press the

83
Operation
6.6.3 ENGINE RUNNING
In manual mode, the load is not transferred to the generator unless a ‘loading request’ is made.
A loading request can come from a number of sources.
• Pressing the transfer to generator button.
• Request from DSE8660 mains controller or from another DSE8610 controller over the MSC
link.
• Activation of an auxiliary input that has been configured to remote start on load
• Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs.
NOTE: The load transfer signal remains inactive until the Oil Pressure has risen. This
prevents excessive wear on the engine.
If the common bus is measured to be ‘dead bus’, the load breaker is closed.
If the bus is measured to be ‘live bus’, synchronising takes place before the breaker is closed.
Once the load has been transferred to the generator, the load switch will not be automatically opened

Dead Bus Synchronising (Auto Mode)
7 DEAD BUS SYNCHRONISING (AUTO MODE)
Generator set specifications often contain the requirement for the set to be on load within 15 seconds
of a mains supply failure. This is easily achievable in single set applications. However in the current
era of fuel conservation, multiple sets are often used to provide the backup power solution for many
applications. This gives challenges in starting and synchronising the required sets before they can be
used to power the load.
The solution to this is a longstanding one, having being used for many decades. However modern
digital communications such as the DSE MSC link has vastly improved the control and hence safety of
the system operation. The solution is called “Dead Bus Synchronising”
7.1 OPERATION
Before the generator sets are started, the load switches are closed. This requires DC controlled
breakers. Next, the alternator excitation field is disconnected from the AVRs and the engines are
started.
Once running satisfactorily, the AVR is reconnected to the excitation field and load sharing begins.
The MSC link is used to ensure all sets excite the alternator at exactly the same time. Any sets not up
to speed before the end of the “Excitation Delay” timer are instructed to open their breakers. A short
time later, these sets synchronise to the bus in the traditional manner.

Protections
8.1 PROTECTIONS DISABLED
User configuration is possible to prevent Shutdown / Electrical Trip alarms from stopping the engine.
Under such conditions, Protections Disabled will appear on the module display to inform the operator
of this status.
This feature is provided to assist the system designer in meeting specifications for “Warning only”,
“Protections Disabled”, “Run to Destruction”, “War mode” or other similar wording.
When configuring this feature in the PC software, the system designer chooses to make the feature
either permanently active, or only active upon operation of an external switch. The system designer
provides this switch (not DSE) so its location will vary depending upon manufacturer, however it
normally takes the form of a key operated switch to prevent inadvertent activation. Depending upon
configuration, a warning alarm may be generated when the switch is operated.
The feature is configurable in the PC configuration software for the module. Writing a configuration to
the controller that has “Protections Disabled” configured, results in a warning message appearing on
the PC screen for the user to acknowledge before the controller’s configuration is changed. This
prevents inadvertent activation of the feature.
8.1.1 INDICATION / WARNING ALARMS
Under Indication or Warning alarms:
• The module operation is unaffected by the Protections Disabled feature. See sections entitled
Indications and Warnings elsewhere in this document.
8.1.2 SHUTDOWN / ELECTRICAL TRIP ALARMS
NOTE: The EMERGENCY STOP input and shutdown alarm continues to operate even
when Protections Disabled has been activated.
Under Shutdown or Electrical Trip alarm conditions (excluding Emergency Stop):
• The alarm is displayed on the screen as detailed in the section entitled Shutdown alarms

• The set continues to run.
• The load switch maintains its current position (it is not opened if already closed)
• Shutdown Blocked also appears on the LCD screen to inform the operator that the
Protections Disabled feature has blocked the shutdown of the engine under the normally

8.7 OVER CURRENT ALARM
The overcurrent alarm combines a simple warning trip level with a fully functioning IDMT curve for
thermal protection.
8.7.1 IMMEDIATE WARNING
If the Immediate Warning is enabled, the DSE8600 Series controller generates a warning alarm as
soon as the Trip level is reached. The alarm automatically resets once the generator loading current
falls below the Trip level (unless All Warnings are latched is enabled). For further advice, consult your
generator supplier.
8.7.2 IDMT ALARM
If the IDMT Alarm is enabled, the DSE8600 Series controller begins following the IDMT ‘curve’ when
the trip level is passed.
If the Trip is surpassed for an excess amount of time the IDMT Alarm triggers (Shutdown or Electric
trip as selected in Action).
High current shutdown is a latching alarm and stops the Generator.
Remove the fault then press Stop/Reset to reset the module.
High current electrical trip is a latching alarm and removes the generator from the load, before
stopping the Generator after the off load cooling timer.
Remove the fault then press Stop/Reset to reset the module.
The higher the overload, the faster the trip. The speed of the trip is dependent upon the fixed formula:
T = t / ( ( IA / I T ) – 1 ) 2
Where: T is the tripping time in seconds
IA is the actual current of the most highly loaded line (L1 or L2 or L3)
IT is the delayed over-current trip point
t is the time multiplier setting and also represents the tripping time in seconds at twice full load (when IA / IT = 2).
Factory settings for the IDMT Alarm when used on a brushless alternator are as follows (screen
capture from the DSE Configuration Suite PC software :
I
(Trip setting
T
t
(time
These settings provide for normal running of the generator up to 100% full load. If full load is
surpassed, the Immediate Warning alarm is triggered, the set continues to run.
The effect of an overload on the generator is that the alternator windings begin to overheat; the aim of
the IDMT alarm is to prevent the windings being overload (heated) too much. The amount of time that
the set can be safely overloaded is governed by how high the overload condition is.
97
Protections
With typical settings as above, the tripping curve is followed as shown below.
This allows for overload of the set to the limits of the Typical Brushless Alternator whereby 110%
overload is permitted for 1 hour.
If the set load reduces, the controller then follows a cooling curve. This means that a second overload
condition may trip much sooner than the first as the controller knows if the windings have not cooled
sufficiently.
For further details on the Thermal damage curve of your alternator, you are referred to your alternator
manufacturer and generator supplier.

8.8 SHORT CIRCUIT AND EARTH FAULT ALARM
When the module is suitably connected using the ‘Earth Fault CT’. The module measures Earth Fault
and can optionally be configured to generate an alarm condition (shutdown or electrical trip) when a
specified level is surpassed.
Short Circuit alarm operates in the same way as the Earth Fault, using the same curve formula, but
typically uses a lower value for K (time multiplier) to give a faster acting trip.
If the Alarm is enabled, the DSE8610 Series controller begins following the IDMT ‘curve’. If the current
surpasses the Trip for an excess of time, the Alarm triggers (Shutdown or Electric trip as selected in
Action).
The higher the fault, the faster the trip. The speed of the trip is dependent upon the fixed formula:
T = K x 0.14 / ( ( I / Is)
Where: T is the tripping time in seconds (accurate to +/- 5% or +/- 50ms (whichever is the greater)
K is the time multiplier setting
I is the actual earth current measured
Is is the trip setting value
0.02
-1 )
