HGM8110DC-2 GENSET CONTROLLER USER MANUAL
13 INSTALLATION
13.1 OVERALL DIMENSION
Controller is panel built-in design; it is fixed by clips when installed. The controller's overall and cutout
dimensions are as below.
Fig.6 - Overall Dimensions
13.2 BATTERY VOLTAGE INPUT
HGM8110DC-2 controller can suit for wide range of battery voltage DC(8~35)V. Negative of battery must be
connected with the engine shell. Diameter of wire that connects from power supply B+ and B- to battery
2
positive and negative must be over 2.5mm
. If floating charger is configured, please firstly connect output
wires of charger to battery's positive and negative directly, then, connect wires from battery's positive and
negative to controller's positive and negative input terminals in order to prevent charger disturbing the
controller's normal working.
13.3 SPEED SENSOR INPUT
Speed sensor is the magnetic equipment installed in engine body to detect flywheel teeth. Its connection
wires to controller should apply 2-core shielding line. The shielding layer should connect to No. 16 terminal
in controller while another side is hanging in air. The other two signal wires are connected to No.17 and
No.18 terminals of controller. The output voltage of speed sensor should be within AC(1~24)V (effective
value) at full speed. AC12V is recommended (at rated speed). When installs the speed sensor, let the
sensor spun to contacting flywheel first, then, port out 1/3 lap, and lock the nuts of sensor at last.
13.4 OUTPUT AND EXPAND RELAYS
CAUTION: All outputs of controller are relay contact output type. If it needs to expand the relays, please add freewheel
diode to both ends of expand relay's coils (when coils of relay has DC current) or, increase resistance-capacitance return
circuit (when coils of relay has AC current), in order to prevent disturbance to controller or other equipments.
13.5 AC INPUT
Current input of controller must be connected to outside 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 collected current and active power may not be correct.
NOTE: ICOM terminal must be connected to negative pole of controller power.
