Automatic Start/Stop Operation - Smartgen HGM410E User Manual

4.3 AUTOMATIC START/STOP OPERATION

Auto mode is selected by pressing the
illuminate to confirm the operation.
Auto Start Sequence,
1) HGM420E: when mains is abnormal (over/under voltage, loss of phase), enter into
"Mains Abnormal Delay" and LCD displays count down time. When the delay is over,
"Start Delay" timer is initiated.
2) HGM410E: When "Remote Start" is active, "Start Delay" timer is initiated;.
3) "Start Delay" countdown will be displayed on LCD;
4) When start delay is over, preheat relay energizes (if configured), "preheat delay XXs"
information will be displayed on LCD;
5) After the above delay, the Fuel Relay is energized, and then one second later, the
Start Relay is engaged. The engine is cranked for a pre-set time. If the engine fails to
fire during this cranking attempt then the fuel relay and start relay are disengaged for
the pre-set rest period; "crank rest time" begins and wait for the next crank attempt.
6) Should this start sequence continue beyond the set number of attempts, the start
sequence will be terminated, the first line of LCD display will be highlighted with
black and Fail to Start fault will be displayed.
7) In case of successful crank attempt, the "Safety On" timer is activated, allowing Low
Oil Pressure, High Temperature, Under speed, Charge Alternator Failure and Aux.
inputs (configured) to stabilise without triggering the fault. As soon as this delay is
over, "start idle" delay is initiated (if configured).
8) During "start idle" delay, under speed, under frequency, under voltage alarms are
inhibited. When this delay is over, "warming up" delay is initiated (if configured).
9) After the "warming up" delay, if generator status is normal, its indicator will be
illuminated. If generator voltage and frequency have reached on-load requirements,
then the generator close relay will be energized; genset will take load; generator
power indicator will illuminate and generator will enter into Normal Running status. if
voltage or frequency is abnormal, the controller will initiate shutdown alarm (alarm
information will be displayed on LCD).
Auto Stop Sequence,
1) HGM420E: during normal running process, if mains normal, enters into "Mains
Normal Delay". When mains indicator illuminates, "Stop Delay" begins.
2) HGM410E: When the "Remote Start" signal is removed, the Stop Delay is initiated.
