2 INTRODUCTION
This document details the installation and operation requirements of the DSE7400 Series modules,
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. 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 DSE7400 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 DSE7400 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. Additionally, the DSE7420 automatically starts and stops the generator set
depending upon the status of the mains (utility) supply.
The user also has the facility to view the system operating parameters via the LCD display.
The DSE7400 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.
• Communications capability (RS485, RS232 or Ethernet)
• Engine parameter monitoring.
• Fully configurable inputs for use as alarms or a range of different functions.
• Engine ECU interface to electronic engines.
Using a PC and the DSE Configuration Suite software allows alteration of selected operational
sequences, timers, alarms and operational sequences. 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..
Access to critical operational sequences and timers for use by qualified engineers, can be protected
by a security code. Module access can also be protected by PIN code. Selected parameters can be
changed from the module’s front panel.
The module is housed in a robust plastic case suitable for panel mounting. Connections to the
module are via locking plug and sockets.

3.5.1 VA RATING OF THE CTS
The VA burden of the module on the CTs is 0.5VA. 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.
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 measurin
g
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).
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.

3.5.2 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.

TO LOAD SWITCH DEVICE
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.
3.5.3 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.
3.5.4 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 lev el you wish to protect against, and
at the accuracy lev el 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
labelled as p1,
k
or K
labelled as p2,
l
or L

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.

DSE Part number 020-013 - Magnetic Pickup probe 5/8 UNF 4” thread length
Magnetic Pickup devices can often be ‘shared’ between two or more dev ices. For example, one
device can often supply the signal to both the module and the engine governor. The possibility of this
depends upon the amount of current that the magnetic pickup can supply.

3.7.2.2 UNDERVOLTAGE (UV COILS)
Use output C, the normally closed relay :
Generator
DSE output drives the contactor coil, via external slave relay if required.
When the DSE module requires the contactor closed, the output energises (closing the internal
relay)
When the DSE module requires the contactor to be open, the output is de-energised (opening
the internal relay)
Generator
DSE output drives the UV coil, via external slave relay if required.
When the generator starts, the UV is powered via the normally closed relay. The breaker is now
ready for the close signal to be given. When the breaker is to be opened, the Open Gen erator
Pulse relay is operated, removing power from the UV coil for one second. This
causes the
breaker to trip (open) as the UV is no longer
powered. The Open Generator Pulse relay switches
back to its closed state, ready to power the UV coil the next time the generator starts.

3.9 COMMUNICATION PORT USAGE
3.9.1 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 to access these engine parameters with no physical connection to the
sensor dev ice.
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 No. 057-004

3.9.2 USB CONNECTION
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 generator, selecting operating modes, etc.
Additionally, the various operating parameters (such as output volts, oil pressure, etc.) of the remote
generator are available to be viewed or changed.
To connect a module to a PC by USB, the following items are required:
• DSE7400 series module
• DSE Configuration Suite PC Software
(Supplied on configuration suite software CD or available from
www.deepseaplc.com).
• USB cable Type A to Type B.
(This is the same cable as often used between a PC and a USB
printer)
DSE can supply this cable if required :

3.9.4 RS232
The RS232 port on the controller supports the Modbus RTU protocol.
The Gencomm register table for the controller is available upon request from the DSE Technical
Support Department.
RS232 is for short distance communication (max 15m) and is typically used to connect the controller
to a telephone or GSM modem for more remote communications.
Many PCs are not fitted with an internal RS232 serial port. DSE DOES NOT recommend the use of
USB to RS232 convertors but can recommend PC add-ons to provide the computer with an RS232
port.
3.9.4.1 RECOMMENDED PC RS232 SERIAL PORT ADD-ONS
Remember to check these parts are suitable for your PC. Consult your PC supplier for further advice.
• Brainboxes PM143 PCMCIA RS232 card (for laptop PCs)
• Brainboxes VX-001 Express Card RS232 (for laptops and nettops PCs)
• Brainboxes UC246 PCI RS232 card (for desktop PCs)

• Sierra Fastrak Xtend GSM modem kit (PSU, Antenna and modem)*
DSE Part number 0830-001-01
NOTE: *For GSM modems a SIM card is required, supplied by your GSM network provider
:
• For SMS only, a ‘normal’ voice SIM card is required. This enables the controller to send SMS
messages to designated mobile phones upon status and alarm conditions.
• For a data connection to a PC running DSE Configuration Suite Software, a ‘special’ CSD
(Circuit Switched Data) SIM card is required that will enable the modem to answer an
incoming data call. Many ‘pay as you go’ services will not provide a CSD (Circuit Switched
Data) SIM card.

3.9.5 RS485
The RS485 port on the series controller supports the Modbus RTU protocol.
The DSE Gencomm register table for the controller is av ailable 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 (1.2km 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 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.
NOTE:- For a single module to PC connection and distances up to 6m (8yds) the USB
connection method is more suitable and provides for a lower cost alternative to RS485 (which
is more suited to longer distance connections).
3.9.5.1 RECOMMENDED PC RS485 SERIAL PORT ADD-ONS

3.9.6.5 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 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 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 (setting from software “Modbus Port Number”) 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 serv er’ 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:- Refer to DSE7400 Series Configuration Suite Manual (DSE part 057-160) for further
details on configuring, monitoring and control.

Maximum 40 additional inputs (All can be configured as either digital,
resistive, 0-10V or 4-20mA when using DSE2131)
NOTE: As a termination resistor is internally fitted to the host controller, the host
controller must be the ‘first’ unit on the DSENet®. A termination resistor MUST be fitted to the
‘last’ unit on the DSENet®. For connection details, you are referred to the section entitled
‘typical wiring diagram’ elsewhere in this document.
NOTE : DSE7400 series module does not support the DSE2510/2520 display modules.
3.10.1 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.
Example of configuring the DSENet® for connection to Cummins QST GCS using the DSE
Configuration Suite Software:

3.11 SOUNDER
The module features an internal sounder to draw attention to warning, shutdown and electrical trip
alarms.
Sounder level 64db @ 1m
3.11.1 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 connection for other terminals or devices. The simplest way to achieve this is to run a
SEPARATE earth connection from the system earth star point, to terminal 15 directly, and not
use this earth for other connections.
NOTE: - If you use PTFE insulating tape on the sensor thread when using earth return
sensors, ensure you do not insulate the entire thread, as this will prevent the sensor body
from being earthed via the engine block.

4.3.9 CT LOCATION
NOTE: CT Location is not applicable to the DSE7410 auto start controllers and is only
available in DSE7420 V1.3 .
There are two possible locations for the current transformers in the system:
1) Generator: The CTs are used to measure and display generator current only. The typical wiring
diagrams in the preceding section all show the CT measuring the generator load. For clarity, an
example is shown below.
2) Load : The CTs are used to measure and display generator current when the generator is on load
and mains current when the mains is on load. The module display automatically changes to
display the current in the relevant instrumentation page. This example shows the CTs in the ‘load’
for a three phase delta system but the same philosophy is applicable to the other topologies.

5.4.6 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 module is powered 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
module. At regular intervals after power up, the modem is reset, and reinitialised, to ensure the
modem does not ‘hang up’.
If the 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 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.

Modem Setup Sequence
1)
If the Modem and module communicate successfully:
2)
In case of communication failure between the modem and 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
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.

5.4.7 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.
The 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 (The module) and may (in control
systems) also send request to change operating modes etc. Unless the Master makes a request, the
slav e is ‘quiet’ on the data link.
The factory settings are for the module to communicate at 19200 baud, modbus slave address 10.
To use the RS485 port, ensure that ‘port usage’ is correctly set using the DSE Configuration Suite
Software.
Required settings are shown below.
‘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 Gencomm document containing register mappings inside the DSE module is
available upon request from [email protected]. Email your request along with the serial
number of your DSE module to ensure the correct information is sent to you.

5.5 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 modules 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.
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).
If the module is configured and connected to send SMS text

6 OPERATION
6.1 CONTROL
Control of the module is via push buttons mounted on the front of the module with STOP/RESET,
MANUAL, TEST, AUTO, ALARM MUTE and START functions. For normal operation, these are the
only controls which need to be operated. The smaller push buttons are used to access further
information such as mains voltage or to change the state of the load switching dev ices when in
manual mode. Details of their operation are provided later in this document.
The following descriptions detail the sequences followed by a module containing the standard ‘factory
configuration’. Always refer to your configuration source for the exact sequences and timers observed
by any particular module in the field.
CAUTION: - The module may instruct an engine start event due to external influences.
Therefore, it is possible for the engine to start at any time without warning. Prior to
performing any maintenance on the system, it is recommended that steps are taken to remove
the battery and isolate supplies.
NOTE: - This control module has PLC functionality built in. This can have change the
standard operation when used. (Default configuration the no PLC is set. See software manual
for more information)

6.2 CONTROL PUSH-BUTTONS
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.
Test (DSE7420 only)
This button places the module into its ‘Test’ mode. This allows an on load
test of the generator.
Once in Test
mode the module will respond to the start button, start
the engine, and run on load.
For further details, please see the more detailed description of ‘Test 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.
Mute / Lamp Test
This button silences the audible alarm if it is sounding and illuminates all of the
LEDs as a lamp test feature/

6.3 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 module front panel
configuration editor).
Page 78
Operation
78
6.4 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.
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. W hen
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.
NOTE:- Refer to DSE7400 Series Configuration Suite Manual (DSE part 057-160) for further
details on configuration.
Page 79
Operation
79
6.5 STOP MODE
STOP mode is activated by pressing the button.
In STOP
mode, the module will remove the generator from load (if necessary) before stopping
the engine if it is already running.
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.

6.5.1 ECU OVERRIDE
NOTE:- ECU Override function is only applicable when the controller is configured for a
CAN engine.
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 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.
.
• The ECU will remain powered 2 minutes 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.

DSE7420 - Load will be transferred from the mains supply to the generator
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 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.
If all start requests are removed, the stopping sequence will begin.
6.8.4 STOPPING SEQUENCE
The return delay timer operates to ensure that the starting request has been permanently removed
and isn’t 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 transferred back from
the generator to the mains supply 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.
After the cooling timer has expired, the set is stopped.

7.1 PROTECTIONS DISABLED
User configuration is possible to prev ent Shutdown / Electrical Trip alarms from stopping the engine.
Under such conditions, Protections Disabled will appear on the m odule 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.
7.1.1 INDICATION / WARNING ALARMS
Under Indication or W arning alarms:
• The module operation is unaffected by the Protections Disabled feature. See sections entitled
Indications and Warnings elsewhere in this document.
7.1.2 SHUTDOWN / ELECTRICAL TRIP ALARMS

7.7 HIGH CURRENT SHUTDOWN / ELECTRICAL TRIP ALARM
The overcurrent alarm combines a simple warning trip level with a fully functioning IDMT curve for
thermal protection.
7.7.1 IMMEDIATE WARNING
If the Immediate Warning is enabled, the 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.
7.7.2 IDMT ALARM
If the IDMT Alarm is enabled, the 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
I
A
is the actual current of the most highly loaded line (L1 or L2 or L3)
I
T
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 I
A
/ IT = 2).
Page 97
Protections
97
Factory settings for the IDMT Alarm when used on a brushless alternator are as follows (screen
capture from the DSE Configuration Suite PC software :
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.
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
suff iciently.
For further details on the Thermal damage curve of your alternator, you are referred to your alternator
manufacturer and generator supplier.

7.8 EARTH FAULT SHUTDOWN / ELECTRICAL TRIP 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 lev el is surpassed.
If the Earth Fault alarm is enabled, the controller begins following the IDMT ‘curve’. If the Trip is
surpassed for an excess amount of time the Alarm triggers (Shutdown or Electric trip as selected in
Action).
The higher the Earth Fault, the faster the trip. The speed of the trip is dependent upon the fixed
formula :
T = K x 0.14 / ((I / Is)
0.02
-1)
Where: T is the tripping time in seconds (accurate to +/- 5% or +/- 50ms (whichever is the greater)
K is the time mu ltiplier setting
I is the actual earth current measured
Is is the trip setting value

7.9 SHORT CIRCUIT ALARM
If the Short Circuit alarm is enabled, the controller begins following the IDMT ‘curve’. If the Trip is
surpassed for an excess amount of time the Alarm triggers (Shutdown or Electrical trip as selected in
Action).
The higher the Short Circuit, the faster the trip. The speed of the trip is dependent upon the fixed
formula :
T = K x 0.14 / ((I / Is)
0.02
-1)
Where: T is the tripping time in seconds (accurate to +/- 5% or +/- 50ms (whichever is the greater)
K is the time mu ltiplier setting
I is the actual current measured
Is is the trip setting value
