DSE Model 560 Automatic Start Engine Management and Instrumentation System Operators Manual
560 OPERATING MANUAL ISSUE 5 4/4/02 MR 7
1.2 AUTOMATIC MODE OF OPERATION
Turning the selector switch to the AUTO position activates the module .
When a Remote Start signal is applied to the remote start input, the following sequence is
initiated:-
The Remote Start Active indicator illuminates (if configured).
To allow for false signals the Start Delay timer is initiated, after this delay, if the pre-heat output
option is selected this timer is then initiated, and the corresponding auxiliary output which is
selected energises.
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 is energised, then the Starter Motor is engaged.
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 accompanied by a flashing red LED.
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 808 interface.) The warning lamp output of
the charge alternator can also be used to disconnect the starter motor, however it cannot be used
for underspeed or overspeed.
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 removal of the Remote Start signal, the Stop delay timer is initiated, once it times 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 Remote Start signal be re-activated during the cooling down period, the set will return
on load.
