1 OVERVIEW
HGM8110A/8120A genset controllers are especially designed for extremely high/low
temperature environment (-40~+70)°C. The controllers can operate reliability in extreme
temperature conditions with the help of VFD display and the components that resist
extreme temperature. All display information is Chinese (English is optional). Operation
information, status information and faults information are all displayed which make
commissioning convenience for factory personnel. Controller can be used under
complex electromagnetic interference environment with the strong ability of
anti-electromagnetic interference. Easy to maintain and upgrade due to the plug-in
terminal.
HGM8110A/8120A genset controllers integrate digitization, intelligentization and network
technology which are used for genset automation and monitor control system of single
unit to achieve automatic start/stop, data measure, alarm protection and “four remote”
(remote control, remote measuring, remote communication and remote regulating).
HGM8110A/8120A genset controllers adopt micro-processor technology with precision
parameters measuring, fixed value adjustment, time setting and set value adjusting and
etc..Majority parameters can be configured from front panel, and all parameters can be
configured by RS485 interface (or RS232) to adjust via PC. It can be widely used in all
types of automatic genset control system with compact structure, advanced circuits,
simple connections and high reliability.

4.4 AUTOMATIC OPERATION
Press , its indicator lights, and controller enters Auto mode.
Starting Sequence,
1. HGM8120A: When Mains is abnormal (over and under voltage, over and under
frequency), it enters into mains “abnormal delay” and VFD display count down time.
When mains abnormal delay is over, it enters into “start delay”;
2. HGM8110A:Generator enters into “start delay” as soon as “Remote Start” is active.
3. “Start Delay” timer is shown on VFD display.
4. When start delay is over, preheat relay outputs (if this be configured), “preheat delay
XX s” is shown at the bottom line of VFD.
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 signal and Fail
To Start message appears on VFD 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 and Aux. input (if
configured) 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 energised, 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 VFD display).
NOTE: In case of “Remote Start (off Load)”, the procedure is the same, except for step
NO. 9: the closing relay will NOT be energised, generator will NOT accept load.
Stopping Sequence
1) HGM8120A：If mains turns normal during genset is running, enter into mains voltage
“normal delay” and its indicator illuminates after mains is confirmed normally, “Start
delay” is beginning.
2) HGM8110A：Genset enters into “stop delay” as soon as “Remote Start” input is

HGM8110A/8120A Genset Controller
HGM8110A/8120A Genset Controller ISSUE2016-9-28 Version1.6 Page 19 of 63
inactive.
3) HGM8120A：After stop delay ends, enter “cooling time”, and generator close relay is
disconnected, after “switch transfer delay”, mains close relay output, mains is on-load,
generator power supply indicator is extinguishing, and mains power supply indicator is
illuminates.
4) Idle relay is output when the controller enters “idle stop delay”.
5) Enter into “ETS delay” and ETS relay is active. Fuel relay output is disconnected.
6) Genset can automatically judge if it is steady when the controller enters “Genset after
stop time”.
7) After genset stops steadily, enter generator standby status; if genset does not stop,
then controller will alarm (VFD screen display stop failure warn).
8) Enter “generator at rest” as soon as “after stop time” is over.

4.5 MANUAL OPERATION
1) HGM8120A: “Manual Mode” is active when press key and its indicator illuminates.
Press key, then controller enters “Test Mode” and indicator illuminates. Under the
both modes, press key to start genset, and it automatically detects if it starts
successfully and accelerate high speed running. With high temperature, low oil
pressure, over speed and abnormal voltage during diesel genset running, controller
can protect genset to stop effectively and quickly (please refer to No.4~9 of Starting
Sequence for more details). Under “Manual Mode ”, genset on-load is decided by
whether mains are normal or not. If mains are normal, loading switch isn’t transferred;
while mains are abnormal, loading switch is transferred into generator’s side. Under
“Test Mode “, after genset runs well in high speed, no matter mains is normal or
not, loading switch must be transferred into Generator’s side.
2) HGM8110A: “Manual Mode” is active when press key, and its indicator is
illuminates. Then press key to start generator, it automatically detects if it is started
successfully and genset automatically accelerates high speed running. With high
temperature, low oil pressure, over speed and voltage abnormal during diesel genset
running, controller can protect genset to stop effectively and quickly (please refer to
No.4~9 of Starting Sequence for more details). After genset runs well in high speed,
controller will send signal of Generator close.
3) Manual stop: press key can shutdown the running genset (please refer to No.3~7
of Stopping Sequence for more details).
