AUTO START/STOP OPERATION
Press
key and the indicator besides lights on, which means generator is in auto mode.
a) Auto Start Sequence
1) When remote start signal is active or mains failure(over/under voltage) delay is expired,
“Start
Delay” time is initiated;
2) When start delay is over, preheating relay outputs (if configured),
“preheat delay” is initiated;
3) After the above delay, the fuel relay outputs, and one second later, the start relay outputs;
During the starting time if the genset fails to start, fuel relay and start relay stop outputting, enter
“Crank Rest Time” and wait for next start;
4) If the genset fails to start during the set starting attempts, LED indicator will display start failure;
5) If the genset starts successfully during the starting attempts, it enters
“Safety On” time, during
which low oil alarm types are inactive; After
“Safety On” time, it enters “Start Idle Delay” (if
configured);
6)
During “Start Idle Delay”, under frequency and under volt alarms are inhibited; When this delay
is over, “Warming Up Delay” is initiated (if configured);
7)
After the “warming up delay”, genset will enter into Normal Running status. If genset voltage or
frequency is abnormal, controller alarm shutdown will be initiated.
b) Auto Stop Sequence
1) When remote start input is invalid or mains normal delay is expired,
“Stop Delay” time is
initiated;
2)
Once this “stop delay” has expired, the “Cooling Down Delay” is then initiated;
3) When
“Stop Idle Delay” (if configured) starts, idle speed relay outputs;
4) When
“ETS Solenoid Hold” begins, ignition control relay is energized and fuel relay is
de-energized; Genset enters standby status.
