4.6. AUTO START/STOP OPERATION
Auto mode is selected by pressing
operation.
Automatic Start Sequence:
When "Remote Start" is active(6 terminal connect with B-), "Start Delay" timer is initiated;
1)
2)
When start delay is over, preheat relay energizes (if configured), preheat delay starts to count.
3)
After the preheat delay, the Fuel Relay (if configured) is energized, and then one second later,
the Start Relay is engaged. If the engine fails to fire during this cranking attempts then the fuel
relay and start relay are stop to output; "crank rest time" begins and wait for the next crank
attempt.
4)
Should this start sequence continue beyond the set number of attempts, the start sequence will
be terminated,
indicator light is blinking.
In case of successful crank attempt, the "Safety On" timer is activated, allowing Low Oil Pressure,
5)
High Temperature and etc. alarms are without triggering the fault. As soon as this delay is over,
"start idle" delay is initiated (if configured).
During "start idle" delay, under speed, under frequency, under voltage alarms are inhibited.
6)
When this delay is over, "warming up" delay is initiated (if configured).
When "warming up delay" is over, genset start normal running; if generator voltage or frequency
7)
is abnormal, shutdown alarm signals will be sent by the controller.
Automatic Stop Sequence,
When the "Remote Start" signal is removed, the Stop Delay is initiated.
1)
Once this "stop delay" has expired, the Generator Breaker will open and the "Cooling Delay" is
2)
then initiated.
During "Stop Idle" Delay (if configured), idle relay is energized.
3)
"ETS Solenoid Hold" begins, ETS relay is energized while fuel relay is de-energized.
4)
5)
"Fail to Stop Delay" begins, complete stop is detected automatically.
Generator is placed into its standby mode after its "After stop" delay. Otherwise, fail to stop
6)
alarm is initiated.(LCD display
Remark:
a)
When press stop button in auto start status, genset will be stopped and enter into stop mode
simultaneously.
b)
When in process of crank rest delay, preheat and ETS functions are energized when fuel output is
de-energized and crank rest time countdown is less than 7s. After crank rest delay, ETS output is
de-energized, fuel relay starts output, and preheat relay output is off before crank.
