4.3 AUTOMATIC START/STOP OPERATION
Auto mode is selected by pressing the button; a LED besides the button will illuminate to confirm the
operation.
Auto Start Sequence,
1) HGM420N: when mains is abnormal (over/under voltage, loss of phase), enter into “Mains Abnormal
Delay” and LCD displays count down time. “Start Delay” timer is initiated after the delay has expired.
2) HGM410N: When “Remote Start” is active, “Start Delay” timer is initiated;
3) “Start Delay” countdown will be displayed on LCD;
4) When start delay is over, preheat relay energizes (if configured), “preheat delay XXs” information will
be displayed on LCD;
5) After the above delay, the Fuel Relay is energized, and then one second later, the Start Relay is
engaged. The engine is crankedfor a pre-set time. If the engine fails to fire during this cranking attempt
then the fuel relay and start relay are disengaged for the pre-set rest period; “crank rest time” begins
and wait for the nextcrank attempt.
6) This start sequence should continue beyond the set number of attempts, the start sequence will be
terminated, the fifth line of LCD display will be highlighted with black and Fail to Start fault will be
displayed.
7) In case of successful crank attempt, the “Safety On” timer is activated, allowing Low Oil Pressure, High
Temperature, Under speed, Charge Alternator Failure and Auxiliary inputs (configured) to stabilise
without triggering the fault. 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 is initiated (if configured).
9) After the “warming up” delay, if generator status is normal, its indicator will be illuminated. If generator
voltage and frequency have reached on-load requirements, then the generator close relay will be
energized; genset will take load; generator power indicator will illuminate and generator will enter into
Normal Running status. If voltage or frequency is abnormal, the controller will initiate shutdown alarm
(alarm information will be displayed on LCD).
Auto Stop Sequence,
1) HGM420N: During normal running process, if mains normal, enters into “Mains Normal Delay”. When
mains indicator illuminates, “Stop Delay” is initiated.
2) HGM410N: 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”, the mains close relay will be energized; mains will take load; generator
power indicator will extinguish while mains power indicator will illuminate.
4) During “Stop Idle” Delay (if configured), idle relay is energized.
5) “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized.
6) "Fail to Stop Delay" begins, complete stop is detected automatically.
7) Generator is placed into its standby mode after its complete stop. Otherwise, fail to stop alarm is
initiated and the corresponding alarm information is displayed on LCD.

4.4 MANUAL START/STOP OPERATION
1) HGM420N: Manual mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation. In this mode, press button to start the genset, it can
automatically judge crank success and accelerate to high speed running. If high temperature, low oil
pressure, over speed and abnormal voltage occur during genset running, controller can effectively
protect genset to stop (detail procedures please refer to No.4~9 of Auto start sequence). In Manual
Mode, load switch won’t auto-switch. It needs to press to enter close/open interface, it controls
mains switch to close/open by pressing and controls gen switch to close/open by pressing .
2) HGM410N: Manual mode is selected by pressing the button; the LED besides the button will
illuminate to confirm the operation and the genset start. It can automatically judge crank success and
accelerate to high speed running. If high temperature, low oil pressure, over speed and abnormal
voltage occur during genset running, controller can effectively protect genset to stop (detail procedures
please refer to No.4~9 of Auto start sequence). After genset high speed normal running, It needs to
press to enter close/open interface, it controls mains switch to close by pressing and controls
gen switch to open by pressing (gen is on load).
3) Manual stop: pressing key can stop the running genset. (detail procedures please refer to No.3~7
of Auto stop sequence)
4.5 EMERGENCY START
In manual mode, pressing and can compel genset to start. The controller won’t judge whether
the controller has started successfully according to disconnect conditions and the disconnection of starter
needs to control by operators. When operators observed the genset has started successfully, loose the
keys and the controller enter safety delay with start stops to output.
