2PERFORMANCE AND CHARACTERISTICS
HGM8140 military controller: ASM(Aotomatic Start module), it controls generator to start/stop by
detecting DC input voltages or remote start signals.
HGM8140 controller contains two modules: HGM8140M (host module) and HGM8140D
(display module). Two modules are communicate with each other by RS232 or CAN BUS port.
HGM8140M(host module): it is used for collecting genset parameters, monitoring and protecting
genset, and realizing genset auto start /stop function.
HGM8140D(display module): it is used for displaying genset‟s parameters, adjusting parameters
and controlling genset by the keys on the front panel of controller.
Main features are as follows:
132x64 LCD with backlight, selectable language interface (Chinese, English and Spanish),
push-button operation.
Hard-screen acrylic material been used to protect screen with great wear-resisting and
scratch-resisting functions.
Silicone panel and pushbuttons can be used in extreme temperature environment.
RS485 communication interface enable “Three remote functions” (remote control, remote
measuring and remote communication) according to MODBUS protocol.
ETHERNET communication port can achieve multi-monitoring modes.
Equipped with CAN BUS port and can communicate with J1939 genset. Not only can monitor
frequently-used data (such as water temperature, oil pressure, speed, fuel consumption and
so on) of ECU machine, but also control starting up, shutdown , raising speed and speed
droop via CAN BUS port (need controller with CANBUS interface).
HGM8140M can connect with HGM8140 D display module, it is convenient to use in special
occasions. HGM8140 D can be set as RS232 port display module or CAN port display
module via front panel keys operation. HGM8140 D module also be set as enabled/disabled
control, if it is able to control, HGM8140M can be controlled by HGM8140D, otherwise,
HGM8140D without remote control function.
Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire
systems with voltage 120/240V and frequency 50Hz/60Hz;

4.4 AUTO START/STOP OPERATION
Press , its indicator lights, and controller enters Auto mode.
Starting Sequence,
1) HGM8140: Generator enters into “start delay” as soon as “Remote Start” input is active or DC
input volt is below pre-set start volt.
2) Start Delay timer is shown on LCD.
3) When start delay is over, preheat relay outputs (if this be configured), “preheat start
delay XX s” is shown on LCD.
4) 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.
5) If engine crank fails within setting times, the fifth line of LCD turn black and Fail to Start message
appears on fifth line of LCD display at the same time.
6) 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 auxiliary inputs (if configured) are
disabled. As soon as this delay is over, “start idle delay” is initiated (if configured).
7) During “start idle delay”, under speed, under frequency, under voltage alarms are inhibited. When
this delay is over, “warming up delay” starts (if configured).
8) 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 shutdown alarm
(shutdown alarm will be displayed on LCD alarm page).
Stopping Sequence:
1) HGM8140, generator enters into “stop delay” as soon as “Remote Start on Load” is inactive and
DC input volt exceeds pre-set shutdown voltage.
2) 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. Mains on load and generator
indicator extinguished while mains indicator lights.
3) Idle relay is energized as soon as entering “stop idle delay” (if configured).
4) If enter “ETS hold delay”, ETS relay is energized. Fuel relay is deactivated.
5) Then enter gen-set “Fail to stop time”, auto decides whether generator is stopped or not
automatically.

HGM8140 MILITARY GENSET CONTROLLER USER MANUAL
HGM8140 Military Genset Controller Version 1.2 2019-09-12 Page 12 of 56
6) Enter “generator at rest” as soon as “after stop time” is over. If genset fail to stop, controller will
initiate alarms (fail to stop warning shown on LCD).
4.5 MANUAL START/STOP OPERATION
1) HGM8140: Manual mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation; 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 (detail procedures please refer to No.5~8 of Auto start sequence). After genset is
normal running, press button, and genset on load
2) Manual stop: pressing key can stop the running genset. (detail procedures please refer to
No.4~6ofAuto stop sequence)
4.6 EMERGENCY START UP
Simultaneously press and or in manual mode will force generator to crank.
Successful start will not be judged according to crank disconnect conditions, operator will have to
crank the starter motor manually; when operator decides that the engine has fired, he/she should
release the button or disconnect manual force to start input and start output will be deactivated, safety
on delay will be initiated.
