：
When Mains is abnormal (over and under voltage, over and under frequency, loss of phase,
phase sequence wrong), it enters into “mains abnormal delay” and LCD display count down time.
When mains abnormal delay is over, it enters into “start delay”; it also enters into this mode when
“remote start on load” is active.
�
LXC9210
：
Generator enters into “start delay” as soon as “Remote Start on Load” is active.
�
Start Delay timer is shown at the bottom line of LCD.
�
When start delay is over, preheat relay outputs (if this be configured), “preheat start delay XX s” is
shown at the bottom line of LCD.
�
When preheat delay is over, fuel relay outputs 1s and then start relay output; if engine crank fails
during “cranking time”, the fuel relay and start relay deactivated and enter into “crank rest time” and
wait for next crank.
�
If generator crank fails within setting times, controller will send “Fail to start” and the warning will be
shown on LCD at the same time.
�
In case of successful crank attempt, “safety on timer” starts.During this period, low oil pressure, high
water temperature,
under speed, charge failure alarms are disabled. 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” starts (if configured).
�
When “warming up delay” is over, if generator state is normal, its indicator will be illuminated. If
voltage and frequency
has reached on-load requirements,the closing relay will be energized,
generator will accept load, generator power indicator will turn on, and generator will enter Normal
Running state; if voltage and frequency are abnormal, the controller will initiate alarm (alarm type will
be displayed on LCD alarm page).

LXC9220
：
when mains return normal during gen-set running, enters into “mains voltage Normal
delay”. When mains normal delay are over, enter into “stop delay” and mains indicator lights; also can
be into this mode when “remote start on load” is inactive.
�
LXC9210
：
generator enters into “stop delay” as soon as “Remote Start” is inactive.
�
When stop delay is over, close generator relay is un-energized; generator enters into “cooling time
relay”. After “transfer rest time”, close mains relay is energized. Generator indicator extinguishes
while mains indicator lights.
�
Idle relay is energized as soon as entering “stop idle delay”.
�
If enter “ETS hold delay”, ETS relay is energized. Fuel relay is deactivated and decides whether
generator is stopped or not automatically.
�
Then enter “gen-set Completely stop time”, auto decides whether generator is stopped or not
automatically.
�
When the unit is completely stopped, enter the power generation standby mode;If can't stop the alarm
controller.
