4.3 AUTOMATIC START/STOP OPERATION

Auto mode is activated by pressing the
confirms this action.
Starting Sequence,
HGM6120LT: When mains is abnormal (over/under voltage, lack of phase), enter into ―Mains
1)
Abnormal Delay‖ and LCD displays count-down time. When delay is over, ―Start Delay‖ begins.
HGM6110LT: when ―Remote Start‖ input is active, enter into ―Start Delay‖.
2)
―Count- down‖ of start delay is displayed in LCD.
3)
When start delay is over, preheat relay is outputting (if configured), ―Preheat Delay XX s‖ is
4)
displayed in LCD.
5) When preheat delay is over, fuel relay is outputting for 1s and then start relay outputs; if genset
failed to start during ―Crank Time‖, the fuel and start relay stop outputting and enter into ―Crank
Rest Time‖ and wait for next cranking.
If genset failed to start within set start times, the fifth line of LED will turn black and ―Fail to Start‖
6)
alarm will be displayed.
Any time to start genset successfully, it will enter into ―Safe Running‖. During this period, alarms of
7)
low oil pressure, high temperature, under speed, failed to charge and Aux. input (be configured) are
disabled. As soon as this delay is over, genset will enter into ―Start Idle Delay‖ (if configured).
8) During start idle delay, alarms of under speed, under frequency, under voltage are disabled. As
soon as this delay is over, genset will enter into ―Warming up Delay‖ (if configured).
When ―Warming up Delay‖ is over, the indicator is illuminating if gens normal. If voltage and
9)
frequency of engine reach the load requirement, close relay outputs, genset is taking load and
indicator illuminates; if engine voltage or frequency is abnormal, controller will alarm and shutdown
(LCD displays the alarm information).
Stopping Sequence,
HGM6120LT: during normal running, if mains normal, genset will enter into ―Mains Normal Delay‖,
1)
when mains indicator illuminates, ―Stop Delay‖ begins.
HGM6110LT: genset enters into ―Stop Delay‖ as soon as ―Remote Start‖ is inactive.
2)
When ―Stop Delay‖ is over, genset enters into ―Cooling Delay‖. Closing relay is disconnected. After
3)
switch ―Transfer Rest Delay‖, closing relay is outputting, mains is taking load, generator indicator
eliminates while mains indicator illuminates.
When entering ―Stop Idle Delay‖, idle relay is energized to output. (If configured).
4)
When entering ―ETS Delay‖, ETS relay is energized to output, fuel relay output is disconnected.
5)
When entering ―Genset at Rest‖, genset will automatically judge if it has stopped.
6)
7) When genset has stopped, enter into standby mode; if genset failed to stop, controller will alarm
(―Fail to Stop‖ alarm will be displayed in LCD).
