Automatic Stop Sequence:
1. HGM9320MPU(CAN), when mains return normal during genset running, enters into mains
voltage “Normal delay” and its indicator illuminated. When mains normal delay is over,
enter into “stop delay”; also can be into this mode when “remote start on load” is inactive.
2. HGM9310MPU(CAN), When the “Remote Start” signal is removed, the Stop Delay is
initiated.
3. Once this “stop delay” has expired, the Generator Breaker will open and the “Cooling
Delay” is then initiated. After “transfer delay”, close mains relay is energized and mains will
take load. Generator indicator extinguish while mains indicator lights.
4. During “Stop Idle” Delay (if configured), idle relay is energized.
5. “ETS Solenoid Hold” delay begins, ETS relay is energized while fuel relay is de-energized,
complete stop is detected automatically.
6. "Fail to Stop Delay" begins, complete stop is detected automatically.
7. When generator is stop completely, “After stop” delay will be initiated. Otherwise, fail to
stop alarm is initiated and the corresponding alarm information is displayed on LCD. ( If
generator is stop successfully after “fail to stop” alarm has initiated, “After stop” delay will
be initiated and the alarm will be removed)
8. Generator is placed into its standby mode after its “After stop” delay.
