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 for panel, please refers to as following,
Fig.5 - Overall Dimensions
13.2 BATTERY VOLTAGE INPUT
HGM8110DC controller can suit for widely 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 to battery
must be over 2.5mm
2
. If floating charge 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 ports in order to prevent charge disturbing the controller‘s normal
working.
13.3 SPEED SENSOR INPUT
Speed sensor is the magnetic equipment which be installed in starter and for detecting flywheel teeth.
Its connection wires to controller should apply for 2 cores shielding line. The shielding layer should
connect to No. 16 terminal in controller while another side is hanging in air. The else two signal wires are
connected to No.17 and No.18 terminals in controller. The output voltage of speed sensor should be
within AC(1~24)V (effective value) during the full speed. AC12V is recommended (in rated speed). When
install the speed sensor, let the sensor is 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 need 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 others equipment.
