LXC3120:AMF (Auto Mains Failure), updates based on LXC3120, moreover, has mains electric quantity
monitoring and mains/generator automatic transfer control function, especially for automatic system
composed by generator and mains.

4.3.1. Auto Start Sequence,
LXC3120: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.
LXC3110: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
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,
LXC3120:During normal running process, if mains normal, enters into “Mains Normal Delay”. When
mains indicator illuminates, “Stop Delay” begins.
LXC3110: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
4.4. Manual start/stop operation
LXC3120:Manual mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation.
Press key, select “Mode Select”, then choose “Test Mode”. Under the two modes,
press button to start the genset, it can automatically judge crank success and accelerate to high
speed running. If high temperature, low oil pressure, over speed and abnormal voltage occur during
genset running, controller can effectively protect genset to stop. Under Manual Mode, if mains normal,
load breaker won’t transfer; if mains abnormal, load breaker will transfer to generator. Under Test
Mode, after genset high speed normal running, no matter mains normal or not, load will be transferred
LXC3110:Manual mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation; Then press button to start the generator, it can automatically
judge crank success and accelerate to high speed running. If high temperature, low oil pressure, over
speed and abnormal voltage occur during genset running, controller can effectively protect genset to
stop. After genset high speed normal running, controller will send Gen Closed signal.
Manual stop: pressing key can shut down the running genset.
