HGM4100LT GENSET CONTROLLER USER MANUAL
HGM4100LT Genset Controller 2019-01-28 Version1.0 Page 39 of 48
HGM4100LT controller can suit wide range of battery voltage DC(8~35)V. Negative of battery must
be connected with the engine shell. Diameter of wire which connects power supply with battery must be
over 2.5mm
2
. If floating charge is configured, please firstly connect output wires of the charger to
battery’s positive and negative directly, then connect wires from battery’s positive and negative to
controller’s positive and negative input ports in order to prevent charge disturbing the controller’s
normal working.

SPEED SENSOR INPUT
Speed sensor is the magnetic equipment which is installed in the starter for detecting flywheel
teeth. The connection wires with controller should apply 2-core shielding line. The shielding layer
should be connected to No. 17 terminal in the controller and another side is hanging in the air. The else
two signal wires are connected to No.1 and No.17 terminals. The output voltage of speed sensor
should be within AC (1~24)V (effective value) during the full speed range. AC12V is recommended (at
rated speed). When speed sensor is installed, let the sensor spun to contacting flywheel first, then, port
out 1/3 lap, and lock the nuts of sensor at last.

OUTPUT AND EXPAND RELAYS
All controller outputs are relay contact output type. If expansion relay is needed, please add
freewheel diode to both ends of expansion
relay’s coils (when relay coils has DC current) or, increase
resistance-capacitance return circuit (when relay coils has AC current), in order to prevent disturbance
to the controller or other equipments.

AC INPUT
Current input of HGM4100LT controller must be connected to external current transformer. And the
current transformer’s secondary side current must be 5A. At the same time, the phases of current
transformer and input voltage must be correct. Otherwise, the colleceted current and active power may
be not correct.
NOTES:
1)
ICOM port must be connected to negative pole of battery.
2)
When there is loading
current, transformer’s secondary side prohibits open circuit.

WITHSTAND VOLTAGE TEST
When the controller had been installed in the control screen, if it is needed to do the high voltage
test, please disconnect controller’s all terminals, in order to prevent high voltage entering the controller
and damaging it.
