4.3. Automatic start/stop operation
Auto mode is selected by pressing the
button; a LED besides the button will illuminate to confirm the
operation.
4.3.1. Auto Start Sequence,
LXC3X20
：
When mains is abnormal (over/under voltage, loss of phase), enter into “Mains Abnormal
Delay” and LCD displays count down time. When the delay is over, “Start Delay” timer is initiated.
LXC3X10
：
When “Remote Start” is active, “Start Delay” timer is initiated.
“Start Delay” countdown will be displayed on LCD.
When start delay is over, preheat relay energizes (if configured), “preheat delay XXs” information will
be displayed on LCD.
After the above delay, the Fuel Relay is energized, and then one second later, 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.
Should this start sequence continue beyond the set number of attempts, the start sequence will be
terminated, the first line of LCD display will be highlighted with black and Fail to Start fault will be
displayed.
In case of successful crank attempt, the “Safety On” timer is activated, allowing Low Oil Pressure,
High Temperature, Under speed, Charge Alternator Failure and Aux. inputs (configured) to stabilize
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. When this
delay is over, “warming up” delay is initiated (if configured).
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).
4.3.2. Auto Stop Sequence,
LXC3X20
：
During normal running process, if mains normal, enters into “Mains Normal Delay”. When
mains indicator illuminates, “Stop Delay” begins.
LXC3X10
：
When the “Remote Start” signal is removed, the stop delay is initiated.
Once this “stop delay” has expired, the Generator Breaker will open and the “Cooling Delay” is then
initiated. After “Transfer Delay”, the mains close relay will be energized; mains will take load;
generator power indicator will extinguish while mains power indicator will illuminate.
During “Stop Idle” Delay (if configured), idle relay is energized.
“ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized.
"Fail to Stop Delay" begins, complete stop is detected automatically.
Generator is placed into its standby mode after its complete stop. Otherwise, fail to stop alarm is
initiated and the corresponding alarm information is displayed on LCD.
