AUTO START/STOP OPERATION

Press , and the indicator besides is on, which means the genset is in auto start mode.
Start Sequence:
When the remote start input is active, LCD displays countdown and it enters "Start Delay";
1)
LCD displays "Start Delay" countdown;
2)
When start delay is over, preheating relay outputs (if configured), LCD displays "preheat start
3)
delay XX s";
4) When preheating delay is over, fuel relay outputs for 1s and then start relay outputs; during the
start time if the genset does not start successfully, the fuel relay and start relay stop outputting and
neter "crank rest time" for waiting for next start;
5) During the set starting attempts, if the genset does not start successfully, the fifth line of LCD
display window turns black, and at the same time it displays start failure alarm;
If the genset starts successfully in any of the start attempts, "safety on delay" starts. During this
6)
period, low oil pressure, high water temperature, under speed, charging failure and auxiliary inputs
(if configured) alarm types are disabled. As soon as this delay is over, "start idle delay" is initiated (if
configured);
During the process of "start idle delay", under speed, under frequency, under voltage alarms are
7)
inhibited. When this delay is over, "warming up delay" starts (if configured);
When "warming up delay" is over, if generator state is normal, the indicator will be illuminated. If
8)
genset voltage and frequency has reached loading requirements, the Gen close relay will be
energized, generator will work with loading, generator power indicator will turn on, and generator
will enter Normal Running state; if the voltage and frequency are abnormal, the controller will
initiate shutdown alarm (Gen alarm type will be displayed on LCD).
Stop Sequence:
When the remote start input is reactive, "Stop Delay" starts;
1)
2) When the stop delay is over, high-speed cooling delay starts, Gen close relay is disconnected,
and Gen power indicator is off;
3) When stop idling speed delay (if configured) starts, idling speed relay is energized and outputs;
When "ETS hold delay" starts, ETS relay is energized and outputs, and the fuel relay output is
4)
disconnected;
When genset "Fail to stop time" starts, it shall judge whether it stops completely automatically;
5)
6) When the genset stops completely, it enters standby status; if the genset cannot stop, the
controller shall alarm (LCD displays stop failure warning.).
