2 INTRODUCTION
The DSE 5520 Module has been designed to allow the OEM to meet demand for increased
capability within the industry. It has been primarily designed to allow the user to start and stop the
generator and if required, transfer the load to the generator either manually or automatically, or in
the event of the module detecting a mains failure. The user also has facility to view all the system
operating parameters via the LCD display.
Utilising the inbuilt synchronising, volts matching and paralleling functions, the 5520 can also be
used to parallel with the mains supply for no break return, peak lopping or power import / export
functionality and load control.
The DSE 5520 module monitors the incoming AC mains supply for under or over voltage / under or
over frequency and instructs the generating set to start and to supply the load.
The DSE 5520 module also 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 flashing COMMON ALARM LED. Exact failure mode information is indicated by
the LCD display on the front panel.
The powerful Micro-processor contained within the module allows for a range of enhanced
features to be incorporated as standard;
•Full Multi-lingual LCD displays (including non-western character fonts).
•True RMS voltage monitoring.
•Power measurement instrumentation.
•Communications capability (RS485 or RS232 including GSM/SMS functions)
•Check Sync capability
•Automatic Sync capability
•Load control capability
•Fully configurable inputs for use as alarms or a range of different functions.
•Extensive range of output functions using built in relay outputs or relay expansion available.
•CAN instrumentation and diagnostics when connected to a compatible CAN (electronically
controlled) engine controller.
Selective operational sequences, timers and alarm trips can be adjusted by the customer via the
integral front panel configuration editor.
Comprehensive configuration is made using the 5xxx For Windows ™ software and 810 interface
module
Access to critical operational sequences and timers for use by qualified engineers, can be barred
by a security code. Module access can also be barred 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 OPERATION
3.1 CONTROL
Control of the DSE 5520 module is via push buttons mounted on the front of the module with
STOP/RESET, MANUAL, TEST, AUTO, LAMP TEST and 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 engine instruments and load switching
operations. Detail of their operation is covered 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 isolate DC supplies and remove the battery.

3.2 AUTOMATIC OPERATION
3.2.1 MAINS FAILURE
This mode of operation is used to ensure continuity of supply to critical loads during a mains failure
condition. This is the normal mode of operation when installed on a standby generator.
NOTE: - If a digital input configured to panel lock is active, changing module modes
will not be possible. Viewing the instruments and iare NOT affected by panel
lock. If panel lock is active the Panel lock indicator (if configured) illuminates.
This mode is activated by pressing the pushbutton. An LED indicator beside the button
will illuminate to confirm this operation.
Should the mains (utility) supply fall outside the configurable limits for longer than the period of the
mains transient delay timer, the mains (utility) available GREEN indicator LED extinguishes.
To allow for short term mains supply transient conditions, the Start Delay timer is initiated. After
this delay, if the pre-heat output option is selected then the pre-heat timer is initiated and the
corresponding auxiliary output (if configured) will energise.
NOTE: - If the mains supply returns within limits during the Start Delay timer, the unit
will return to a stand-by state.
After the above delays have expired the Fuel Solenoid (or enable ECU output if configured) is
energised, then one second later, the Starter Motor is engaged.
NOTE:- If the unit has been configured for CAN Bus, compatible ECU’s will receive
the start command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-
004 for more information on utilising DSE modules with electronically controlled engines.
The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then
the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond
the set number of attempts, the start sequence will be terminated and Fail to Start fault will be
displayed.
Alarm
Shutdown
Fail to start
When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency
measured from the alternator output. Alternatively, a Magnetic Pickup mounted on the flywheel
housing can be used for speed detection (This is selected by PC using the 5xxx series
configuration software). Rising oil pressure can also be used to disconnect the starter motor;
however it cannot be used for underspeed or overspeed detection.
NOTE:- If the unit has been configured for CAN Bus, speed sensing is via CAN Bus.

10
After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure,
High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to
stabilise without triggering the fault.
Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to
stabilise before accepting the load.
After the Warm-up timer has expired then the module will transfer the load from the failed mains
supply to the generator output. It will observe the following sequence. The Mains
Contactor/Breaker will be instructed to open and after a short delay (transfer delay), the
Generator Contactor/Breaker will be instructed to close.
The generator will then supply the requirements of the load.
NOTE:-A load transfer will not be initiated until the Oil Pressure has risen. This
prevents excessive wear on the engine.
When the mains supply returns, the Stop delay timer is initiated. Once it has expired, the set is
synchronised and paralleled with the mains supply. The system remains in this condition until
expiry of the Parallel run timer. Once this has expired, the module will ramp the remaining load
from the generator to mains supply. The Generator Contact/Breaker will open and the Cooling
timer is then initiated, allowing the engine a cooling down period off load before shutting down.
Once the Cooling timer expires, the Fuel Solenoid is de-energised, bringing the generator to a
stop.
During the parallel run, the module can be configured to either run at a fixed level output, or to
maintain an output in relation to the load level on the mains. For full details of these mode please
refer to the manual ‘The Guide to sync and load share Pt1’
Should the mains supply fall outside limits once again the set will return on load.
NOTE: - When synchronising is enabled, the mains supply is checked before closing
any load switching device. If the supply is live, synchronising will take place before any
closure takes place.
NOTE: - Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details.

3.2.2 REMOTE START IN ISLAND MODE
This mode of operation is used to start the set in response to an external start requirement from
another device. It may also be used to provide continuity of supply during expected black out
events.
NOTE:- If a digital input configured to panel lock is active, changing module modes
will not be possible. Viewing the instruments and iare NOT affected by panel
lock. If panel lock is active the Panel lock indicator (if configured) illuminates.
This mode is activated by pressing the pushbutton. An LED indicator beside the button
will illuminate to confirm this operation.
If the remote start in island mode input activates, the Remote Start Active indicator (if configured)
illuminates.
To allow for false remote start signals, the Start Delay timer is initiated. After this delay, if the pre-
heat output option is selected then the pre-heat timer is initiated and the corresponding auxiliary
output (if configured) will energise.
NOTE:- If the Remote Start signal is removed during the Start Delay timer, the unit
will return to a stand-by state.
After the above delays, the Fuel Solenoid (or enable ECU output if configured) is energised, and
then one second later, the Starter Motor is engaged.
NOTE: - If the unit has been configured for CAN Bus, compatible ECU’s will receive
the start command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-
004 for more information on utilising DSE modules with electronically controlled engines.
The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then
the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond
the set number of attempts, the start sequence will be terminated and Fail to Start fault will be
displayed.

After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure,
High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to
stabilise without triggering the fault.
Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to
stabilise before accepting the load.
NOTE: - A load transfer will not be initiated until the Oil Pressure has risen. This
prevents excessive wear on the engine.
The Generator will first be instructed to synchronise with the mains supply before closing the
Generator Contact/Breaker and transferring load from mains to generator until the generator is
supplying the required amount of power (adjustable using 5xxx configuration software).
When the supplies have been in parallel for the duration of the parallel run time, the load will
ramp off the mains supply and onto the generator. The Mains Contactor/Breaker will be
instructed to open.
The generator will then supply the requirements of the load.
When the remote start signal is removed, the Stop delay timer is initiated. Once it has expired, the
set is synchronised and paralleled with the mains supply.
The system remains in this condition until expiry of the Parallel run timer. Once this has expired,
the module will ramp the remaining load from the generator to mains supply.
The Generator Contact/Breaker will open and the Cooling timer is then initiated, allowing the
engine a cooling down period off load before shutting down.
Once the Cooling timer expires, the Fuel Solenoid is de-energised, bringing the generator to a
stop.
NOTE: - Synchronising can be disabled if the application does not require this
function. Contact your generating set supplier in the first instance for further details.
NOTE: - The internal ‘Scheduler’ can be configured to operate they system in the
same manner as described for the Remote start input. Please refer to the 5xxx
Configuration Software manuals for full details on the feature.

3.2.3 REMOTE START ON LOAD
This mode of operation is used to start the set in response to rising load levels on the mains supply
(if configured).
NOTE: - If a digital input configured to panel lock is active, changing module modes
will not be possible. Viewing the instruments and iare NOT affected by panel
lock. If panel lock is active the Panel lock indicator (if configured) illuminates.
This mode is activated by pressing the pushbutton. An LED indicator beside the button
will illuminate to confirm this operation.
Should the load level on the mains supply exceed a pre-set level the module will initiate a start
sequence.
To allow for short duration load surges, the Start Delay timer is initiated. After this delay, if the pre-
heat output option is selected then the pre-heat timer is initiated and the corresponding auxiliary
output (if configured) will energise.
NOTE: - If the load level returns below the pre-set level during the Start Delay timer,
the unit will return to a stand-by state.
After the above delays, the Fuel Solenoid (or enable ECU output if configured) is energised, and
then one second later, the Starter Motor is engaged.
NOTE: - If the unit has been configured for CAN Bus, compatible ECU’s will receive
the start command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-
004 for more information on utilising DSE modules with electronically controlled engines.
The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then
the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond
the set number of attempts, the start sequence will be terminated and Fail to Start fault will be

After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure,
High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to
stabilise without triggering the fault.
Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to
stabilise before accepting the load.
After the Warm-up timer has expired then the module will transfer the load from the mains supply
to the generator output. It will observe the following sequence.
The Generator will first be instructed to synchronise with the mains supply. Once these are
matched, the Generator Contact/Breaker will be instructed to close.
The load will then be ramped from the Mains to the appropriate level on the generator.
The generator will then supply the requirements of the load.
NOTE: - A load transfer will not be initiated until the Oil Pressure has risen. This
prevents excessive wear on the engine.
When the remote start on load input is removed, the Stop delay timer is initiated. Once this timer
has expired, the module will ramp the load from the generator to mains supply. The Generator
Contact/Breaker will open and the Cooling timer is then initiated, allowing the engine a cooling
down period off load before shutting down. Once the Cooling timer expires, the Fuel Solenoid is
de-energised, bringing the generator to a stop.
During the parallel run, the module can be configured to either run at a fixed level output, or to
maintain an output in relation to the load level on the mains.
NOTE: - When synchronising is enabled, the mains supply is checked before closing
any load switching device. If the supply is live, synchronising will take place before any
closure takes place.
NOTE: - Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details.
NOTE: - The load level mode of operation relies on a Current Transformer (CT) fitted
to the mains feed of the system. This is then used for measurement of the mains current
used in the load level calculations.

selected energised.
After the above delay, the Fuel Solenoid (or ECU output if configured) is energised, and then one
second later, the Starter Motor is engaged.
NOTE:- If the unit is configured for CAN Bus, compatible ECU’s will receive the start
command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-004 for
more information on utilising DSE modules with electronically controlled engines.
The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then
the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond
the set number of attempts, the start sequence will be terminated and Fail to Start will be
displayed.

stabilise without triggering the fault.
Once the engine is running, the Warm Up timer (if selected) is initiated, allowing the engine to
stabilise before it can be loaded. Once the warm up timer has expired, the generator is then
available to go on load and the Generator Available LED will illuminate on the front panel.
The generator will run off load unless:

1. The mains supply fails,
2. A Remote Start on load signal is applied, or an on-load run is configured in the scheduler.
3. The Close Generator button is pressed.
If any of the above signals are received, the generator is synchronised and paralleled with the
mains supply (if available).
During the parallel run, the module can be configured to either run at a fixed level output, or to
maintain an output in relation to the load level on the mains. For full details of these mode please
refer to the manual ‘The Guide to sync and load share Pt1’
Parallel operation:
•If the Close Generator button is pressed again while in parallel, then the module will
transfer the load fully to the generators, removing the load from the mains supply. This will be
achieved by ramping the load from the parallel operating level to the generator. The Mains
Contactor/Breaker will then be opened. Pressing the Close Mains button will cause the
module to re-synchronise the generator with the mains supply and then return to parallel
operation.
•If the Close Mains button is pressed while in parallel, the module will open the generator
load switching device, transferring the load fully to the mains supply.
If Auto mode is selected and the mains supply is healthy, and the remote start on load signal not
active, and the scheduler is not calling for a run, then the Return Delay Timer will start.
Once this has expired then the module will exit parallel operation and will ramp the load back to
the mains supply. It will then open the Generator Contactor/Breaker. The generator will then run
off load allowing the engine a cooling period.
Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.
WARNING: - Operation of the STOP button in any mode will stop the generator
operation and return the load switching system to a safe state. This operation may lead
to loss of supply to the load. It is recommended that the STOP button is only operated
once the generator is OFF LOAD and the mains is supplying the load.
NOTE: - Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details. If
synchronising is disabled the system will always perform an open transition when
switching the load from the mains to the generator or when returning to the mains. The
parallel run stages of the sequence are not used when operating in this way.
NOTE: - When synchronising is enabled, the mains supply is checked before closing
any load switching device. If the supply is live, synchronising will take place before any
closure takes place.

3.4 TEST OPERATION
Test operation is used to perform a full on load test sequence to allow for diagnosis of faults.
Alternatively, it may also be used to provide continuity of supply during expected black out events,
peak lopping or peak shaving during high tariff periods.
NOTE: - If a digital input configured to panel lock is active, changing module modes
will not be possible. Viewing the instruments and event logs iis NOT affected by
panel lock. If panel lock is active the Panel lock indicator (if configured) illuminates.
TEST mode is initiated by pressing the pushbutton. An LED besides the button will illuminate
to confirm this operation. When the START (I) button is operated, the module will initiate the start
sequence.
NOTE: - There is no Start Delay in this mode of operation.
If the pre-heat output option has been selected, this timer will initiate and the auxiliary output
selected will be energised.
After the above delay, the Fuel Solenoid (or ECU output if configured) is energised, and then one
second later, the Starter Motor is engaged.
NOTE: - If the unit has been configured for CAN Bus, compatible ECU’s will receive
the start command via CAN Bus. Refer to the Manual CAN and DSE Wiring. Part No. 057-
004 for more information on utilising DSE modules with electronically controlled engines.
The engine is cranked for a pre-set time. If the engine fails to fire during this cranking attempt then
the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond
the set number of attempts, the start sequence will be terminated and Fail to Start will be
displayed.
Alarm
Shutdown
Fail to start
When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from
the Alternator output. Alternatively, a Magnetic Pickup mounted on the flywheel housing can be
used for speed detection (This is selected by PC using the 5xxx series configuration software).
Rising oil pressure can also be used to disconnect the starter motor; however, it cannot be used
for underspeed or overspeed detection.
NOTE: - If the unit has been configured for CAN Bus speed sensing is via CAN Bus.
After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure,
High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to
stabilise without triggering the fault.

Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to
stabilise before accepting the load.
After the Warm-up timer has expired then the module will transfer the load from the mains supply
to the generator output. It will observe the following sequence.
The Generator will first be instructed to synchronise with the mains supply. Once these are
matched the Generator Contact/Breaker will be instructed to close.
The load will then be ramped from the Mains to the appropriate level on the generator.
It will remain in this state whilst in the TEST mode.
If the module has an active remote start in island mode input or the internal scheduler has been
configured for island mode then the parallel run time will activate. When this expires, the load will
ramp off the mains supply and onto the generator. The Mains Contactor/Breaker will be
instructed to open
The generator will then supply the requirements of the load.
NOTE:-A load transfer will not be initiated until the Oil Pressure has risen. This
prevents excessive wear on the engine.
The system will then remain in this mode of operation until a different mode is selected. It is
recommended that mode is used to cancel the TEST mode.
When mode is selected the Stop delay timer is initiated. Once it has expired, the set is
synchronised and paralleled with the mains supply. The system remains in this condition until
expiry of the Parallel run timer. Once this has expired the module will ramp the remaining load
from the generator to mains supply. The Generator Contact/Breaker will open and the Cooling
timer is then initiated, allowing the engine a cooling down period off load before shutting down.
Once the Cooling timer expires the Fuel Solenoid is de-energised, bringing the generator to a
stop.
During the parallel run the module can be configured to either run at a fixed level output, or to
maintain an output in relation to the load level on the mains. For full details of these mode please
refer to the manual ‘The Guide to sync and load share Pt1’
NOTE:- When synchronising is enabled, the mains supply is checked before closing
any load switching device. If the supply is live, synchronising will take place before any
closure takes place.
NOTE:- Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details.
