14 INSTALLATION
14.1 FIXING CLIPS
Controller is panel built-in design; it is fixed by clips when installed.
Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
Pull the fixing clip backwards (towards the back of the module) ensuring two clips are inside their
allotted slots.
Turn the fixing clip screws clockwise until they are fixed on the panel.
Note: Care should be taken not to over tighten the screws of fixing clips.
14.2 OVERALL DIMENSION
Figure 9 - Overall Dimensions
HGM7100N series 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 2.5mm2. 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.
a) SPEED SENSOR INPUT
Speed sensoris the magnetic equipmentwhich 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. 18 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 (1~24) VAC (effective value) during the full speed. 12VAC 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.
b) OUTPUT AND EXPAND RELAYS
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.
c) AC INPUT
Current input of HGM7100N series controller must be connected to outside current transformer. And
