4.3 AUTOMATIC START/STOP OPERATION
Auto mode is activated by pressing the , LED indicator beside the button is illuminating which
confirms this action.
Starting Sequence,
1) HGM6120U2C: When mains is abnormal (over/under voltage, lack of phase), enter into “Mains
Abnormal Delay” and LCD displays count-down time. When delay is over, “Start Delay” begins.
2) HGM6110U2C: when “remote start” input is active, enter into “Start Delay”.
3) “Count- down” of start delay is displayed in LCD.
4) When start delay is over, preheat relay is outputting (if configured), “Preheat Delay XX s” is 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.
6) If genset failed to start within set start times, the fourth line of LED will turn black and Fail to Start alarm
will be displayed.
7) Any time to start genset successfully, it will enter into “Safe Running”. During this period, alarms of low
oil pressure, high temperature, under speed, charge failure 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).
9) When “Warming up Delay” is over, the indicator is illuminating if gens normal. If voltage and 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,
1) HGM6120U2C: during normal running, if mains normal, genset will enter into “Mains Normal Delay”,
when mains indicator illuminates, “Stop Delay” begins.
2) HGM6110U2C: genset enters into “Stop Delay” as soon as “Remote Start” is inactive.
3) When “Stop Delay” is over, genset enters into “Cooling Delay”. Closing relay is disconnected. After
switch “Transfer Rest Delay”, closing relay is outputting, mains is taking load, generator indicator
eliminates while mains indicator illuminates.
4) When entering “Stop Idle Delay”, idle relay is energized to output. (If configured).
