12. INSTALLATION
12.1. FIXING CLIPS
1)
Controller is panel built-in design; it is fixed by clips when installed.
2)
Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
3)
Pull the fixing clip backwards (towards the back of the module) ensuring two clips are inside
their allotted slots.
4)
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.
12.2. OVERALL DIMENSION
Overall and cutout dimensions as follows,
BATTERY VOLTAGE INPUT
HGM1790N 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 1.5mm
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 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. 1 terminal in controller while another side is hanging in air. The else two signal
wires are connected to No.1 and No.10 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.
