DSE Model 5210 Automatic Start Engine Management and Instrumentation System Operators Manual
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 one second later, 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 shutdown symbol.
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 5200 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.
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 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 Remote Start signal be re-activated during the cooling down period, the set will return on load.
