INSTALLATION
12.1
FIXING CLIPS
1)
The module is designed for panel installation, and fixed by fixing clips.
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 make contact with the panel.
NOTE:
Care should be taken not to over tighten the screws of fixing clips.

OVERALL DIMENSION AND PANEL CUTOUT
Fig.8 Case Dimension and Cutout Size
HGM400N series controller can suit for widely range of battery voltage DC(8~35)V. Negative of battery
must be connected with the engine shell. The diameter of wire from power supply to battery 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 ports in order to prevent charger disturbing the controller’s
normal working.
1)
Speed Sensor Input
Speed sensor is the magnetic equipment installed in starter and for detecting flywheel teeth. Its
connection wires to controller should apply 2 cores shielding line. The shielding layer should connect to
No. 17 terminal in controller while another side is hanging in air. The other two signal wires are
connected to No.1 and No.17 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 the speed sensor is installed, let the sensor is spun to contacting flywheel first, then, port out 1/3
lap, and lock the nuts of sensor at last.
2)
Output and Expansion Relay
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 have DC current) or, add
resistance-capacitance return circuit (when coils of relay have AC current), in order to prevent
disturbance for controller or other equipment.
