4.2 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 event logs is NOT affected by panel lock.
Activate auto mode be pressing the pushbutton. An LED indicator beside the button confirms this action.
Auto mode will allow the generator to operate fully automatically, starting and stopping as required with no user
intervention.
4.2.1 WAITING IN AUTO MODE
If a starting request is made, the starting sequence will begin.
Starting requests can be from the following sources :
•
Mains supply out of limits (DSE7220/7320 only)
•
Activation of an auxiliary input that has been configured to remote start
•
Activation of the inbuilt exercise scheduler.
4.2.2 STARTING SEQUENCE
To allow for ‘false’ start requests such as mains brownouts, the start delay timer begins.
Should all start requests be removed during the start delay timer, the unit will return to a stand-by state.
If a start request is still present at the end of the start delay timer, the fuel relay is energised and the engine will be
cranked.
NOTE:- If the unit has been configured for CAN, compatible ECU’s will receive the start command via
CAN.
If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the crank rest duration
after which the next start attempt is made. Should this sequence continue beyond the set number of attempts, the
start sequence will be terminated and the display shows Fail to Start.
When the engine fires, the starter motor is disengaged. Speed detection is factory configured to be derived from the
main alternator output frequency but can additionally be measured from a Magnetic Pickup mounted on the flywheel
(Selected by PC using the 7000 series configuration software).
Additionally, rising oil pressure can be used to disconnect the starter motor (but cannot detect underspeed or
overspeed).
NOTE:- If the unit has been configured for CAN, speed sensing is via CAN.
After the starter motor has disengaged, the Safety On timer activates, allowing Oil Pressure, High Engine
Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.
