during "cranking time", the fuel relay and start relay deactivated and enter "crank rest time" to wait for
next crank.
6.
If engine crank fails within setting times, the controller sends Fail to Start signal and Fail to Start
message appears on LCD alarm page.
7.
In case of successful crank attempt, "safety on timer" starts. During this period, low oil pressure, high
water temperature, under speed, charge failure alarms are disabled. 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" starts (if configured).
9.
When "warming up delay" is over, if generator state is normal, its indicator will be illuminated. If
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 alarm (alarm type will
be displayed on LCD alarm page).
NOTE: In case of "Remote Start (off Load)", the procedure is the same, except for step NO. 9: the closing relay will NOT
be energized, generator will NOT accept load.
Stopping Sequence:
1.
HGM9620: When mains return normal during gen-set running, it enters mains voltage "normal delay".
When mains normal delay is over, enter "stop delay"; also can be into this mode when "remote start on
load" is inactive.
2.
HGM9610: Generator enters "stop delay" as soon as "remote start on load" is inactive.
3.
When stop delay is over, close generator relay is un-energized; generator enters into "cooling down
time". After "transfer rest time", close mains relay is energized. Generator indicator extinguish while
mains indicator lights.
4.
Idle relay is energized as soon as entering "stop idle delay".
5.
If enter "ETS hold delay", ETS relay is energized. Fuel relay is deactivated and decides whether
generator is stopped or not automatically.
6.
Then enter gen-set "Fail to stop time", auto decides whether generator is stopped or not
automatically.
7.
Enter "after stop time" (if configured) as soon as generator stops. Otherwise, controller will send "Fail
to Stop" alarm. (If gen-set stopped successfully after warning of "Fail to Stop", it will enter "after stop
time" and remove alarm)
8.
Enter "generator at rest" as soon as "after stop time" is over.
