DSE Model 5320 Automatic Mains Failure & Instrumentation System Operators Manual
Part No. 057-014 5320 OPERATING MANUAL ISSUE 5.1 18/06/2007 ADM 5
1 INTRODUCTION
The DSE 5320 automatic mains failure module has been primarily designed to monitor the mains (utility) supply,
starting the generator automatically should it fall out of limits. Transfer of the load is automatic upon a mains supply
failure. If required the generator and can be started and stopped manually, and if required, the user can transfer
the load to the generator either manually (via external push-buttons) or automatically. The user also has the facility
to view all the system operating parameters via the LCD display.
The DSE 5320 module monitors the mains (utility) supply indicating the status of the mains on the module’s
integral LCD display. Additionally the 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
flashing COMMON AUDIBLE ALARM. The exact failure mode is indicated by text messages on the LCD display on
the front panel.
The powerful microprocessor contained within the module allows for a range of complex features to be
incorporated as standard:
•Text based LCD display (supporting multiple languages).
•Voltage, Current and Power monitoring.
•Engine parameter monitoring.
•Fully configurable inputs for use as alarms or a range of different functions.
•Extensive range output functions using built in relay outputs or relay expansion available.
Selective operational sequences, timers and alarm trips can be altered by the customer via a PC using the 5xxx
series configuration software and P810 interface. Additionally, a subset of this information can be adjusted from the
module’s front panel configuration editor.
The module is housed in a robust plastic case for front panel mounting. Connections to the module are via locking
plug and sockets.

3.1 AUTOMATIC MODE OF OPERATION
NOTE:- If a digital input configured to panel lock is active, changing module modes will not be
possible. Viewing the instruments and iis 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 confirms this
action.
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. Additionally, while in AUTO mode, the
remote start input (if configured) is monitored. If active, the Remote Start Active indicator (if configured)
illuminates.
Whether the start sequence is initiated by mains (utility failure) or by remote start input, the following sequence is
observed :
To allow for short term mains supply transient conditions or 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 mains supply returns within limits, ( or the Remote Start signal is removed if the start
sequence was initiated by remote start) 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, then one second
later, the Starter Motor is engaged.
NOTE:- If the unit has been configured for CAN, compatible ECU’s will receive the start command
via CAN.
The engine is cranked for a pre-set time period. 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
Failed 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, speed sensing is via CAN.

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.
If an auxiliary output has been selected to give a load transfer signal, this would then activate.
NOTE:-A load transfer will not be initiated until the Oil Pressure has risen. Thus preventing
excessive wear on the engine.
On the return of the mains supply, (or removal of the Remote Start signal if the set was started by remote signal) ,
the Stop delay timer is initiated, once it has timed out, the load Transfer signal is de-energised, removing the load.
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.
Should the mains supply fall outside limits again (or the Remote Start signal be re-activated) during the cooling
down period, the set will return on load.

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 it
can be loaded.
The generator will run off load, unless the mains supply fails or a Remote Start on load signal is applied. If Close
generator has been selected as a control source, the appropriate auxiliary output will then activate.
The generator will continue to run On load regardless of the state of the mains supply or remote start input until the
Auto mode is selected.
If Auto mode is selected, and the mains supply is healthy with the remote start on load signal not active, then the
Remote Stop Delay Timer begins, after which, the load is disconnected. The generator will then run off load
allowing the engine a cooling down period.
Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.

remains it will not be possible to reset the unit (The exception to this is the Low Oil Pressure alarm and
similar ‘delayed alarms’, as the oil pressure will be low with the engine at rest).
FAIL TO START, if the engine does not fire after the pre-set number of attempts has been made a shutdown will
be initiated. Alarm Shutdown Fail To Start will be displayed.

4.5 HIGH CURRENT SHUTDOWN ALARM
GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the pre-set trip a
warning is initiated. This warning will continue for a period of time depending upon the level of overload that the
generator is subjected to, and the configuration setting for Generator High Current in the 5xxx series configuration
software.
Alarm
Shutdown
High current trip
For instance the factory default settings for Generator High Current allow for a loading of the generator to 110% for
one hour. That is to say if the generator load level exceeds the trip point by 10%, a warning alarm will occur while
the overload condition exists. If the load level does not drop to normal levels within one hour, the set is stopped,
the 5320 module displaying either shutdown alarm or electrical trip alarm depending upon module configuration.
NOTE:- Higher overload levels will result in a faster acting shutdown condition. For instance with
the factory default configuration, an overload level twice that of the trip level ( typically 200%) will result
in a Generator High Current shutdown condition after 36 seconds.
For details of the relationship between the overload and the shutdown time, please see the Appendix
section of this manual.

4.6 ELECTRICAL TRIPS
Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the electrical trip
condition the module will de-energise the ‘Close Generator’ Output to remove the load from the generator. Once
this has occurred the module will start the Cooling timer and allow the engine to cool off-load before shutting down
the engine. The alarm must be accepted and cleared, and the fault removed to reset the module.
AUXILIARY INPUTS, if an auxiliary input has been configured as an electrical trip the appropriate message will be
displayed as configured by the user.
Example
Alarm

GENERATOR HIGH CURRENT. If the module detects a generator output current in excess of the pre-set trip a
warning is initiated. If this high current condition continues for an excess period of time, then the alarm is escalated
to either a shutdown or electrical trip condition (depending upon module configuration). For further details of the
high current alarm, please see High Current Shutdown Alarm.
