3.2. Automatic start/stop operation
Press ,and the indicator besides the key illuminates, which indicates unit is in auto start mode.
3.2.1. Starting sequence:
Press ，then the button indicating lamp bright. The generator is in “automatic start mode”. In the
automatic mode, the generator will be auto to start and stop according requirement (no need any human
action). In this mode, three type starting request can trigger starting process.
The 1st one is mains failure (over voltage, under voltage, over frequency, under frequency , simulation of
mains failure enter valid).(This condition is valid only for LXC620)
The 2nd one is the remote start input or SMS remote start .
The last one is the schedule running.
Once the start request is triggered and no fault, began to perform automatic boot sequence:
Start Delay timer is shown on Status page of LCD；
When start delay is over, preheat relay outputs (if this be configured),“preheat start delay XX s”is
shown in 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”to wait
for next crank;
If engine crank fails within setting times, the controller sends Fail to Start signal and “Fail To Start”
message appears on LCD alarm page;
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).
NOTE: In case of “Remote Start (off Load)”, the procedure is the same, except for step NO. 7: the
closing relay will NOT be energized, generator will NOT accept load.

3.2.2.Stopping sequence:
LXC620：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.
LXC610：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.Then began "cooling delay", and during the period if mains failure or
remote start is active,generator return to the gens on load.
Idle relay is energized as soon as entering “stop idle delay”.
In the "stop idle delay" after the end,if enter“ETS hold delay”, ETS relay is energized. Fuel relay is
deactivated and decides whether generator is stopped or not automatically.；
In the "ETS delay" after the end,then enter genset "Fail to stop timer",auto decides whether generator
is stopped or not.
When the generator stopped,enter the standby generator;If the generator does not stop the controller
alarm(LCD Screen Display Shutdown failure warning).
3.2.3.Manual start/stop operation:
LXC620: Press , controller enters into Manual mode and its indicator lights. Press then
controller enters into "Manual Test Mode"and its indicator lights. In the both mode, press to start
generator, can automatically detect crank disconnected, and generator accelerates to high-speed
running. With high temperature, low oil pressure and abnormal voltage during generator running,
controller can protect genset to stop quickly (please refer to No.4~9 of Auto start operation for
detail procedures). In“manual mode ”, the procedures of ATS please refer to ATS procedure of
generator in this manual.In“Manual Test Mode ”, generator runs well, whether mains normal or
not, loading switch must be transferred to generator side.
LXC610: Press , controller enters into Manual starts mode and its indicator lights. Then
press to start generator, can automatically detect crank disconnected, and generator accelerates
to high-speed running. With high temperature, low oil pressure and abnormal voltage during
generator running, controller can protect genset to stop quickly (please refer to No.4~9 of Auto start
operation for detail procedures). After generator runs well, if remote start signal is active, controller
will send closing gens signal; if the remote signal is inactive, controller won‟t send closing signal.
Manual shop:press can shutdown the running generator(please refer to No.3~8 of stopping
sequence for detail procedures）

3.3. Switch control procedures
3.3.1.LXC620 ATS switch control procedures
Auto transfer procedures:
When controller is in Manual Test, Auto or Stop mode, switch control procedures will start through
automatic transfer.
Note: When the input port has the following configuration of situations:
1If input port is configured as Close Mains/Gens Auxiliary
When transferring load from mains to generator, controller begins detecting “fail to transfer”, then the
open delay and transfer rest delay will begin. When detecting time out, if switch open failed, the
generator will not switch on, otherwise, generator switch on. Detecting transfer failure while gens
switch on. When detecting time up, if switch on fail, it is need to wait for generator to switch on. If
transfer failed and warning“SELECT Enable”, there is alarming signal whatever switch on or off
failure.
The way to transfer from generator load to mains load is as same as above.
Note: the above is in the middle position switch.
2If input port is not configured as Close Mains/Gens Auxiliary
Mains load be transferred into gens load, after switch off and transfer interval delay, gens switch on.
The way to transfer gens load to mains load is as same as above.
Note: The above configuration is for an no-air-hang type ATS. But it can also be used for an
air-hang type ATS.
When controller is in Manual mode, manual transfer will be executive. After the generator normal starting,
when mains failure or remote start input is valid, mains switch off, then gens switch on.If you have
configured closing state input, during switching transitions also need to check the input state of closing
signals. If fail to close or open it will generate an alarm.
3.3.2.LXC610 Switch control procedures
Auto control procedures,
When controller is in manual test, auto or stop mode, switch control procedures will start auto transfer.
After the generator starting successfully, gens switch on. When the remote start signal fail, gens switch
off.
If input port is configured as Close Mains Auxiliary，Gens load is transferred into generator un-load, after
the delay of switch off, detecting transfer failure while switch off output. When detecting time up, if switch
off failed, to wait for switch off. Otherwise, switch off is completed. Gens unload is transferred into gens
load, after the delay of switch on, detecting transfer failure while switch on outputting. When detecting
time up, if switch on failed, to wait for switch on. Otherwise, switch on is completed.If transfer failed and
warning “SEL Enable”, there is alarming signal whatever switch on or off failure.
If input port is not connected with closing breaker signal，gens un-load is transferred into gens load,
gens switch on and output. Gens load is transferred into gens un-load, gens switch off and output.

Manual control procedures:
When controller is in Manual mode, manual transfer will be executive:
After the generator starting successfully,when remote start input is active, gens switch.on.When gens is
on load, if the remote start input fail, it will not uninstall or shutdown. But uninstall or shutdown will happen
when the conversion to automatic mode or pressing the Stop button . If you have configured the switch
status input, you also need to check the input state of signals. If fail to close it will generate an alarm.
4. SMS remote control、wireless remote control
This feature allows users to use GSM mobile communication terminal device for remote control.When
generators are running , if you want to stop the genset unit, you can send text messages to mobile phone
code“ SMS STOP MODE”. When the controller return code “SMS STOP MODE OK”, it means that genset
has got the command and try to stop.
