5.4 AUTO START/STOP OPERATION
Press , its indicator lights, and controller enters Auto mode.
Starting Sequence,
1) HGM8120N: 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 countdown
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.
2) HGM8110N: Generator enters into “start delay” as soon as “remote start (on load)” is active.
3) Start Delay timer is shown on LCD.
4) When start delay is over, preheat relay outputs (if this be configured), “preheat start
delay XX s” is shown on LCD.
5) 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.
6) If engine crank fails within setting times, the controller sends Fail to Start signals and Fail to Start
message appears on LCD alarm page.
7) 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).
8) During “start idle delay”, under speed, under frequency, under voltage alarms are inhibited. When this
delay is over, “warming up delay” starts (if configured).
9) 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. 9: the closing relay will NOT
be energized, generator will NOT accept load.
Stopping Sequence:
1) HGM8120N:When mains returns normal during gen-set running, it enters into mains voltage
“normal delay”. When mains normal delay is over, it enters into “stop delay”; it also can enter into this
mode when “remote start” is inactive.
2) HGM8110N: Generator enters into “stop delay” as soon as “remote start (on load)” is inactive.
3) When stop delay is over, close generator relay is un-energized; generator enters into “cooling down
time”. After “transfer rest time”, close mains relay is energized. Generator indicator extinguish while
mains indicator lights.
4) Idle relay is energized as soon as entering “stop idle delay”.
5) If enter “ETS hold delay”, ETS relay is energized. Fuel relay is deactivated and decides whether
generator is stopped or not automatically.
6) Then enter gen-set “Fail to stop time”, auto decides whether generator is stopped or not
automatically.
7) Enter “after stop time” (if configured) as soon as generator stops. Otherwise, controller will send
“Fail to stop” alarm. (If gen-set stopped successfully after warning of “Failed to Stop”, it will enter
“after stop time” and remove alarm)
8) Enter “generator at rest” as soon as “after stop time” is over.

high-speed running automatically. With high temperature, low oil pressure and abnormal voltage
during generator running, controller can protect genset to stop quickly. Press (HGM8120N) or
press and (HGM8110N) to open or close the switch. (Please refer to No.4~9 of Auto start
operation for detail procedures, which the difference is only the way of switch open and close).
2) MANUAL STOP: Press can stop the running generators. (Please refer to No.3~8 of Auto
stop operation for detail procedures).
NOTE: In “manual mode”, the procedures of ATS please refer to ATS procedure of generator in this manual.

5.6 GENSET CONTROLLER SWITCH CONTROL PROCEDURES
5.6.1. HGM8120N SWITCH CONTROL PROCEDURES
5.6.1.1. MANUAL TRANSFER PROCEDURES
When controller is in Manual mode, the switch control procedures will start through manual transfer.
Users can control the loading transfer of ATS via pressing button to switch on or off.
A. If “Open breaker detect” is selected “Disable”
Press generator switch on or off key , if generator has taken load, it will send open signals; if
taken no load, it will send gen close signals; if mains has taken load, mains will open breaker, and
then generator will close after open delay over.
Press mains switch on or off key , if mains has taken load, it will send open signals; if taken no
load, it will send mains close signals; if generator has taken load, generator will open breaker, and
then mains will close after open delay over.
B. If “Open breaker detect” is selected “Enable”
To transfer load from mains to generator need to press mains switch on or off key firstly. After
switch off delay, press generator switch on or off key , and generator will close breaker. (there is
no action when pressing generator switch on or off key directly.)
The way to transfer load from generator to mains is as same as above.
5.6.1.2. AUTO TRANSFER PROCEDURES
When controller is in AUTO mode, switch control procedures will start through automatic transfer.
1) If input port is configured as Close Mains Auxiliary
A. If “Open breaker detect” is selected “Enable”
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
generator switch on. When detecting time out, if switch on fail, it needs to wait for generator to
switch on. If transfer failure warning is selected “Enable”, there is warning signals whatever switch on
or off failure.
The way to transfer load from generator to mains is as same as above.
B. If “Open breaker detect” is selected “Disable”
Mains load is transferred into generator load, after the delay of switch off and transfer interval,
generator switch on. Detecting transfer failure while generator switches on. After detecting time out,
if switch on fail, then wait for generator switch on. If transfer failure warning is selected “Enable”,
there is warning signals.
2) If input port is not configured as Close Mains Auxiliary
Mains load is transferred into generator load, after switch off and transfer interval delay, generator
switch on.
The way to transfer generator load to mains load is as same as above.

5.6.2. HGM8110N SWITCH CONTROL PROCEDURES
5.6.2.1. MANUAL CONTROL PROCEDURES
When controller is in Manual mode, manual control will be executive.
Users can control switch on or off by pressing and key.
Press generator switch on key , generator will output load signals. Press generator switch off key
, generator will output unload signals.
5.6.2.2. AUTO CONTROL PROCEDURES
When controller is in auto mode, switch control procedures will start auto transfer.
1) If input port is configured as Close Mains Auxiliary
A. If “Open breaker detect” is selected “Enable”
Generator load is transferred into generator un-load, after the delay of switch off, detecting transfer
failure while switch off output. When detecting time out, if switch off failed, it will wait for switch off.
Otherwise, switch off is completed.
Generator unload is transferred into generator load, after the delay of switch on, detecting transfer
failure while switch on outputting. When detecting time out, if switch on failed, it will wait for switch
on. Otherwise, switch on is completed.
If transfer failure warning is selected “Enable”, there is warning signals whatever switch on or off
failure.
B. If “Open breaker detect” is selected “Disable”
Generator load is transferred into generator unload, after the delay of switch off, switch off is
completed.
Generator unload is transferred into generator load, after the delay of switch on, detecting transfer
failure while switch on outputting. When detecting time out, if switch on failed, to wait for switch on.
Otherwise, switch on is completed.
If transfer failure warning is selected “Enable”, there is warning signal when “switch on fail”.
2) If input port is not configured as Close Mains Auxiliary
Generator un-load is transferred into generator load, close generator output.
Generator load is transferred into generator un-load, open generator output.
NOTE:
1) When using ATS of no interposition, switch off detecting should “SELECT Disable”;
2) When using ATS of having interposition, switch off “SELECT Disable” or “SELECT Enable” both are OK. If choose
“SELECT Enable”, switch off output should be configured;
3) When using AC contactor, switch off “SELECT Enable” is recommended.
