4.4 AUTO START/STOP OPERATION

Press , its indicator lights, and controller enters Auto mode.
Starting Sequence,
HGM8140: Generator enters into "start delay" as soon as "Remote Start" input is active or DC
1)
input volt is below pre-set start volt.
2) Start Delay timer is shown on LCD.
When start delay is over, preheat relay outputs (if this be configured), "preheat start
3)
delay XX s" is shown on LCD.
4) When preheat delay is over, fuel relay outputs 1s and then start relay output; if engine crank fails
during "cranking time", the fuel relay and start relay deactivated and enter into "crank rest time" to
wait for next crank.
5) If engine crank fails within setting times, the fifth line of LCD turn black and Fail to Start message
appears on fifth line of LCD display at the same time.
In case of successful crank attempt, "safety on timer" starts. During this period, low oil pressure,
6)
high water temperature, under speed, charge failure alarms and auxiliary inputs (if configured) are
disabled. As soon as this delay is over, "start idle delay" is initiated (if configured).
During "start idle delay", under speed, under frequency, under voltage alarms are inhibited. When
7)
this delay is over, "warming up delay" starts (if configured).
When "warming up delay" is over, if generator state is normal, its indicator will be illuminated. If
8)
voltage and frequency has reached on-load requirements, the closing relay will be energized,
generator will accept load, generator power indicator will turn on, and generator will enter Normal
Running state; if voltage and frequency are abnormal, the controller will initiate shutdown alarm
(shutdown alarm will be displayed on LCD alarm page).
Stopping Sequence:
HGM8140, generator enters into "stop delay" as soon as "Remote Start on Load" is inactive and
1)
DC input volt exceeds pre-set shutdown voltage.
When stop delay is over, close generator relay is un-energized; generator enters into "cooling
2)
down time". After "transfer rest time", close mains relay is energized. Mains on load and generator
indicator extinguished while mains indicator lights.
Idle relay is energized as soon as entering "stop idle delay" (if configured).
3)
If enter "ETS hold delay", ETS relay is energized. Fuel relay is deactivated.
4)
Then enter gen-set "Fail to stop time", auto decides whether generator is stopped or not
5)
automatically.
