4.6. AUTO START/STOP OPERATION
Auto mode is selected by pressing
operation.
Automatic Start Sequence:
1)
When "Remote Start" is active (6 terminal connected with B-), "Start Delay" timer is initiated;
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 genset fails to fire during "Cranking Time", then the fuel relay
and start relay 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.
5)
In case of successful crank attempt, the "Safety On" timer is activated, Low Oil Pressure, High
Temperature and other alarms are inactive during the period. As soon as this delay is over,
"Start Idle" delay is initiated (if configured).
6)
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).
When "Warming up" delay is over, genset starts normal running; if generator voltage or
7)
frequency is abnormal, shutdown alarm signals will be sent by the controller.
Automatic Stop Sequence,
When the "Remote Start" signal is removed, "Stop Delay" is initiated.
1)
Once this "Stop Delay" has expired, the "Cooling Delay" is then initiated.
2)
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)
"Fail to Stop Delay" begins, complete stop is detected automatically.
5)
Generator is placed into its standby mode after its "After stop" delay. Otherwise, fail to stop
6)
alarm is initiated.(LCD display
NOTE:
a)
When press stop button in auto start status, genset will stop and enter into stop mode simultaneously.
b)
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.
4.7. MANUAL START/STOP OPERATION
1)
MANUAL START: Press
Sequence for detail procedures). With high temperature, low oil pressure, over speed and
abnormal voltage during generator running, controller can protect genset to stop quickly.
