AUTO START/STOP OPERATION
Press
, its indicator lights, and controller enters
Auto
mode.
Starting Sequence,
1)
HGM8110DC:
Generator enters into ―Start Delay‖ as soon as ―Remote Start on Load‖ is active.
2) Start delay timer is shown on LCD.
3) When start delay is ove
r, preheat relay outputs (if this be configured), ―Preheat Start
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 controller sends
―Fail to Start‖ signals and ―Fail to Start‖
message appears on LCD alarm page.
6) In case of success
ful 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).
7)
During ―Start Idle Delay‖, under speed, under frequency, under voltage alarms are inhibited. When
this delay is over, ―Warming Up Delay‖ starts (if configured).
8)
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. 8: the closing relay
will NOT be energized, generator will NOT accept load.
Stopping Sequence:
1)
HGM8110DC
, generator enters into ―stop delay‖ as soon as ―Remote Start‖ is inactive.
2)
When stop delay is over, close generator relay is un-
energized; generator enters into ―Cooling Time‖.
Generator indicator extinguish while mains indicator lights.
3)
Idle relay i
s energized as soon as entering ―Stop Idle Delay‖.
4)
If enter ―ETS hold delay‖, ETS relay is energized. Fuel relay is deactivated and decides whether
generator is stopped or not automatically.
5)
Then enter gen-
set ―Fail to stop time‖, auto decides whether generator is stopped or not
automatically.
6)
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 ―Failed to Stop‖, it will enter
―After Stop Time‖ and remove alarm)
7)
Enter
―Generator at Rest‖ as soon as ―After Stop Time‖ is over.
