Operation
4.3 AUTO START/STOP OPERATION
Auto mode is selected by pressing the button; a LED besides the button will illuminate to confirm the
operation.
Automatic Start Sequence:
1. When “Remote Start” is active, “Start Delay” timer is initiated;
2. “Start Delay” countdown will be displayed on LCD;
3. When start delay is over, preheat relay energizes (if configured), “preheat delay XX s”
information will be displayed on LCD;
4. After the above delay, the Fuel Relay is energized, and then one second later, the throttle of
the driving stepper motor will rotate as the pre-set angle and then the Start Relay is engaged.
The engine is cranked for 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 next crank attempt.
5. Should this start sequence continue beyond the set number of attempts, the start sequence
will be terminated, the fourth line of LCD display will be highlighted with black and Fail to Start
fault will be displayed.
6. In case of successful crank attempt, the “Safety On” timer is activated and the throttle of
the driving stepper motor will govern the speed, allowing Low Oil Pressure, High Temperature,
Under speed, Charge Alternator Failure and auxiliary inputs (be configured) to stabilise without
triggering the fault. 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 is initiated (if configured).
8. 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).
Automatic Stop Sequence:
1. When the “Remote Start” signal is removed, the Stop Delay is initiated.
2. Once this “stop delay” has expired, the Generator Breaker will open and the “Cooling Delay” is
then initiated. Moreover, the generator indicator is extinguished.
3. During “Stop Idle” Delay (if configured), idle relay is energized.
4. “ETS Solenoid Hold” delay begins, ETS relay is energized while fuel relay is de-energized.
5. "Fail to Stop Delay" begins, complete stop is detected automatically.
6. When generator is stop completely, generator is placed into its standby mode. Otherwise, fail
to stop alarm is initiated and the corresponding alarm information is displayed on LCD.
