1 OVERVIEW
HGM400E series 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
“three remote” (remote control, remote measuring and remote communication; SG485
module must be fitted). It fit with LCD display, optional languages interface (Chinese,
English, Spanish and Russian), and it is reliable and easy to use.
HGM400E series genset controllers adopt micro-processor technology with precision
parameters measuring, fixed value adjustment, time setting and set value adjusting
and etc. All parameters can be configured from front panel or through programmable
interface (USB to LINK, can use SG72 adaptor) 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.

4.3 AUTOMATIC START/STOP OPERATION
Auto mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation.
Auto Start Sequence,
1) HGM420E: when mains is abnormal (over/under voltage, loss of phase), enter into
“Mains Abnormal Delay” and LCD displays count down time.When the delay is over,
“Start Delay” timer is initiated.
2) HGM410E: When “Remote Start” is active, “Start Delay” timer is initiated;.
3) “Start Delay” countdown will be displayed on LCD;
4) When start delay is over, preheat relay energizes (if configured), “preheat delay XXs”
information will be displayed on LCD;
5) After the above delay, the Fuel Relay is energized, and then one second later, the
Start Relay is engaged. The engine is cranked fora pre-set time. If the engine fails to
fire during this cranking attempt then the fuel relay and start relay are disengaged for
the pre-set rest period; “crank rest time” begins and wait for the next crank attempt.
6) Should this start sequence continue beyond the set number of attempts, the start
sequence will be terminated, the first line of LCD display will be highlighted with
black and Fail to Start fault will be displayed.
7) In case of successful crank attempt, the “Safety On” timer is activated, allowing Low
Oil Pressure, High Temperature, Under speed, Charge Alternator Failure and Aux.
inputs (configured) to stabilise without triggering the fault. 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 is initiated (if configured).
9) After the “warming up” delay, if generator status is normal, its indicator will be
illuminated. If generator voltage and frequency have reached on-load requirements,
then the generator close relay will be energized; genset will take load; generator
power indicator will illuminate and generator will enter into Normal Running status. if
voltage or frequency is abnormal, the controller will initiate shutdown alarm (alarm
information will be displayed on LCD).
Auto Stop Sequence,
1) HGM420E: during normal running process, if mains normal, enters into “Mains
Normal Delay”. When mains indicator illuminates, “Stop Delay”begins.
2) HGM410E: When the “Remote Start” signal is removed, the Stop Delay is initiated.

HGM400E Series Automatic Control Module
HGM400E Series Genset Controller ISSUE 2013-08-28 Version 1.1 Page 12 of 41
3) Once this “stop delay” has expired, the Generator Breaker will open and the “Cooling
Delay” is then initiated. After “Transfer Delay”, the mains close relay will be
energized; mains will take load; generatorpower indicator will extinguish while mains
power indicator will illuminate.
4) During “Stop Idle” Delay (if configured), idle relay is energized.
5) “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized.
6) "Fail to Stop Delay" begins, complete stop is detected automatically.
7) Generator is placed into its standby mode after its complete stop. Otherwise, fail to
stop alarm is initiated and the corresponding alarm information is displayed on LCD.
4.4 MANUAL START/STOP OPERATION
1) HGM420E: Manual mode is selected by pressing the button; a LED besides the
button will illuminate to confirm the operation; Press key, select “Mode Select”,
then choose “Test Mode”. Under the two modes, press button to start the genset,
it can automaticallyjudge 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.4~9 of Auto start sequence). Under Manual Mode , if mains normal,
load breaker won’t transfer; if mains abnormal, load breaker will transfer to generator.
Under Test Mode, after genset high speed normal running, no matter mains normal
or not, load will be transferred to generator.
2) HGM410E: Manual mode is selected by pressing the button; a LED besides the
button will illuminate to confirm the operation; Then press button to start the
generator, 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.4~9 of Auto start sequence). After genset high speed
normal running, controller will send Gen Closed signal.
3) Manual stop: pressing key can shut down the running genset. (detail procedures
please refer to No.3~7 of Auto stop sequence)
