4.3 AUTOMATIC START/STOP OPERATION
This mode is activated by pressing . LED indicator beside the key is illuminating
which confirms this action.

Start Sequence,
1) HGM420: when mains is abnormal (over/under voltage, lack of phase), enter into
“Mains Abnormal Delay” and LCD displays count-down timer. When the delay is
over, “Start Delay” begins.
2) HGM410: genset enters into “Start Delay” when “Remote Start” is active.
3) Count- down timer of “Start Delay” is displayed in LCD.
4) When start delay is over, preheat relay is outputting (if configured), “Preheat Delay
XX s” is displayed in LCD.
5) When preheat delay is over, fuel relay is outputting 1s and then start relay outputs; if
genset failed to start during “Start Time”, fuel and start relays stop outputting and
enter into “Crank Rest Time” and wait for next cranking.
6) If genset failed to start within specified start times, the fourth line of LED will turn
black and “Fail to Start” alarm will be displayed.
7) Whatever time to start successfully, genset will enter into “Safety on Run Time”.
During this period, alarms of low oil pressure, hi-temperature, under speed, charge
failure and auxiliary input (be configured) are disabled. As soon as this delay is over,
genset will enter into “Start Idle Delay” (if configured).
8) During start idle delay, alarms of under speed, under frequency, under voltage are
disabled. As soon as this delay is over, genset will enter into “Warming Up Delay” (if
configured).
9) When “Warming Up Delay” is over, the indicator is illuminating if gens normal. If
engine voltage and frequency reach the load demand, closing relay outputs, genset
takes load and indicator illuminates; if engine voltage and frequency appear
abnormal, controller will alarm to shutdown (alarm is displayed in LCD).
Stop Sequence,
1) HGM420: during genset running, if mains normal, enters into “Mains Normal Delay”.
When mains indicator illuminates, “Stop Delay” begins.
2) HGM410: genset enters into “Stop Delay” when “Remote Start” is inactive.
3) When stop delay is over, genset enters into “Cooling Delay”. Gens closing relay is
open. After switch “Transfer Rest Delay”, mains closing relay outputs, mains will take
load, power indicator of gens eliminates while indicator of gens illuminates.
4) When entering “Stop Idle Delay” (if configured), Idle relay is energized to output.
5) When entering “ETS delay”, ETS relay is energized to output, fuel relay is open.
6) When entering “Genset at Rest”, automatically judge whether genset is stopped or
not.

7) When genset has stopped, enters into standby mode; if failed to stop, controller will
alarm (“Fail to Stop” alarm will be displayed in LCD).
4.4 MANUAL START/STOP OPERATION
1) HGM420: Manual Mode is activated when press and its indicator illuminates.
Press key, choose “Manual Test Mode”. Under the two modes, press key to
start genset, it can automatically judge crank disconnect and accelerate to hi-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 operation). Under Manual Mode ,
if mains normal, load switch won’t transfer; if mains abnormal, load switch will transfer
to gens. Under Manual Test Mode, after genset normally runs in high speed, no
matter mains normal or not, load will be transferred to gens.
2) HGM410: Manual Mode is activated when press key and its indicator illuminates.
Then press key to start generator, it can automatically judge crank disconnect and
accelerate to hi-speed running. If hi-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 operation).
Controller will send closing signal when genset runs in high speed.
3) Manual stop: pressing key can shut down the running genset. (detail procedures
please refer to No.3~7 of Auto stop operation)

1) The crank disconnect condition has three kinds, the magnetic pickup and the
generator voltage can be used alone, oil pressure must be used with the magnetic
pickup and the generator voltage, in order to make the starter disconnect as soon
as possible.
2) Magnetic pickup is installed in the engine for testing flywheel.
3) When choosing magnetic pickup, ensure the number of flywheel teeth is same as
the set, otherwise over speed or under speed shutdown may appear.
4) If the generator is not installed with magnetic pickup, please don't select
corresponding item.
5) If the generator has no oil pressure sensor, please don't choose corresponding.
6) If the generator is not selected, controller will not measure and display relative
parameters (This can be applied to the pump set), if not choose magnetic pickup,
the speed signal will come from the generating AC signal.

8 PARAMETERS SETTING
After controller powered on, press to enter into the parameters setting menu, see fig 1
below:
 Set Parameters
When entering password interface, inputting “1234” can set part of the parameter
items in table 1; inputting “0318” can set all the items. (Table 1) If there is need to
set more parameters, please contact the factory.
NOTES:
1. For HGM410, there are no items from 1 to 5 in table 1; there are no digital outputs
about mains in auxiliary output 1-5.
2. Please modify the parameters (such as crank disconnection, auxiliary input/output
and various timers) in standby mode, otherwise alarm to shutdown or other
abnormal conditions may happen.
3. The over-voltage threshold must be greater than the under-voltage threshold;
otherwise over-voltage and under-voltage will occur at the same time.
4. The over-speed threshold must be greater than under-speed threshold, otherwise
over speed and under speed will occur at the same time.
5. Set the frequency (crank disconnect) as low as possible, in order to separate the
starter quickly when crank disconnect.
6. Auxiliary input 1-4 cannot be set as the same item, or will cause incorrect functions.
But auxiliary output 1-5 can be set as the same item.
7. If need to shut down after cooling, please set any auxiliary input as “Coolant To
Stop”, then connect this input to GND.

10 COMMISSIONING
Before operation, the following checking should be carried out:
1) Check and ensure all the connections are correct and wires diameter is suitable.
2) Ensure that the controller DC power has insurance; battery positive and negative
have correctly connected.
3) Emergence stop input must be connected to positive of starting battery via normally
close contact of emergency stop.
4) Take proper actions to prevent engine to disconnect crank (for example, to remove
the connections of fuel value). If checking is OK, connect start battery, select Manual
Mode, controller will execute the program.
5) Set controller as Manual Mode, press “start” button to start genset. If failed within the
setting crank times, controller will send “Failed to Start” signal; then press “Reset” to
reset controller.
6) Recover actions of preventing engine to disconnect crank (e. g. Connect wire of fuel
value), press “start” button again, genset will start. If everything goes well, genset will
normal run after idle running (if configured). During this period, watch for engine’s
running situations and voltage and frequency of alternator. If abnormal, stop genset
and check all connections according to this manual.
7) Select the Auto Mode from front panel, connect to mains signal. After the mains
normal delay, controller will transfer ATS (if configured) and into mains load. After
cooling, controller will stop genset and into standby state until mains abnormal again.
8) When mains abnormal again, genset will start automatically and into normal running,
send signal to make gens close, transfer ATS and make genset take load. If not like
this, please check connections of ATS according to this manual.
9) If there are any other questions, please contact our technical personnel.

12 INSTALLATION
12.1FIXING CLIPS
The module is held into the panel fascia using the supplied fixing clips.
1) Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
2) Pull the fixing clip backwards (towards the back of the module) ensuring four clips
are inside their allotted slots.
3) Turn the fixing clip screws clockwise until they make contact with the panel.
Note: Care should be taken not to over tighten the screws of fixing clips.

12.2 OVERALL DIMENSION AND PANEL CUTOUT
1) Battery Voltage Input
HGM400 series controller can be applicable to (8-35) VDC battery voltage. Battery
negative must be reliably connected engine shell. The connection between
controller power and battery should not be less than 1.5mm2
, if a float charger is
fitted, please directly connect output line of the charger with battery, then from
battery positive and negative separately connect power input, in case that charger
will interfere with the normal running of controller.
2) Speed Sensor Input
Speed sensor is installed in the engine for testing flywheel teeth. The connection
with controller uses 2-core screen, shield layer should connect terminal1 of
controller with the other end vacant. The other two signal lines are respectively

connected to terminal 1 and terminal 17. At full speed, output voltage range is
1-24VAC (RMS). Recommend using 12VAC (rated speed) voltage. During
installing, make the speed sensor contact the flywheel firstly, then pour out 1/3
laps, finally lock nut on the sensor.
3) Output And Expansion Relay
All outputs of the controller are relay contact outputs, if expansion relay is needed,
please add free-wheeling diode at both ends of the relay coil (expansion relay coil
links DC) or increase RC loop (expansion relay coil links AC) in order to prevent
from interfering controller or other equipment.
4) AC Input
HGM400 series controller must externally connect current transformer, CT
secondary current must be 5A. Besides, the phase of CT and input voltage must
be correct, or the sampling current and active power may be incorrect.
CAUTION！ICOM must connect battery anode of the controller.
WARNING! When there is load current; the CT secondary side cannot open
circuit.
5) Withdraw Voltage Test
When the controller has been installed in the control panel, during the test please
disconnect all the terminals, lest high voltage damages the controller.
