Installation
12.2 OVERALL DIMENSION AND PANEL CUTOUT
1. Battery Voltage Input
HSC940 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 which 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.
2. 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.
17 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.
3. Output And Expansion Relay
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, add resistance-capacitance
return circuit (when coils of relay has AC current), in order to prevent disturbance to controller or others
equipment.
4. Withdraw Voltage Test
When controller had been installed in control panel, if need the high voltage test, please disconnect
controller’s all terminal connections, in order to prevent high voltage into controller and damage it.
