procedure h) or i), generator close relay is deactivated, and moreover, genset is off load.

AUTOMATIC STOP SEQUENCE
a)
In the process of genset normal running, if Mains recovers, genset enters "Mains Voltage Normal
Delay". When Mains normal is confirmed, Mains status indicator is illuminated and "Stop Delay" is
initiated. Or when remote start input is inactive, "Stop Delay" is initiated;
b)
After stop delay is over:
1)
Synchronous Transfer Disabled: Cooling Time is initiated, and at the same time gen close relay
is disconnected; after "switch transfer delay", Mains close relay outputs and Mains takes the load;
Gen supply indicator is extinguished and Mains supply indicator is illuminated;
2)
Synchronous Transfer Enabled: Controller issues Mains close signal after waiting for genset and
Mains meeting sync. requirement; when Mains close feedback signal is detected, it immediately
issues Gen open signal; Gen supply indicator is extinguished, and Mains takes the load; Mains
supply indicator is illuminated and Cooling Time is initiated;
c)
At entering "stop idle delay" (if configured), the idling speed relay is energized;
d)
"ETS solenoid hold" begins, ETS relay is energized while fuel relay is de-energized, and complete
stop is detected automatically;
e)
"Fail to stop delay" begins, and complete stop is detected automatically;
f)
When generator is stopped completely, "after stop delay" will be initiated. Otherwise, controller
enters "fail to stop" period, and issues failed to stop alarm (If generator stops successfully after ‗fail to
stop' alarm has initiated, "after stop delay" will be initiated and the alarm will automatically be removed.);
Generator is placed into its standby mode after its ‗after stop delay';
g)
4.5 MANUAL START/STOP OPERATION
a)
HGM9420N_HGM9420LT: Manual mode is selected by pressing the
the button will be illuminated to confirm the operation; then press
detect crank disconnect condition and generator accelerates to high-speed running automatically. With
high temperature, low oil pressure, over speed and abnormal voltage during generator running,
controller can protect genset to stop quickly (please refer to c-i of 4.3.2 Automatic Start Sequence for
detailed procedures).
b)
MANUAL STOP: Press
4.3.3 Automatic Start Sequence for detailed procedures).
