14 INSTALLATION
14.1 ILLUSTRATION
Controller is panel built-in design; it is fixed by clips when installed. The controller's overall dimensions
and cutout dimensions for panel, please refers to as following,
14.2 BATTERY VOLTAGE INPUT
HGM8151 controller can suit for widely range of battery voltage (8~35) VDC. Negative of battery
must be connected to the shell of starter stable. The wire's diameter must be over 2.5mm
connected to B+ and B- of controller power. 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.
14.3 SPEED SENSOR INPUT
Speed sensor is the magnetic equipment which be installed in starter and for detecting teeth of
flywheel. 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.
14.4 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 have DC current) or, increase
resistance-capacitance return circuit (when coils of relay have AC current), in order to prevent
disturbance to controller or others equipment.
14.5 AC INPUT
Current input of controller must be connected to outside current transformer. And the current
transformer's secondary side current must be 5A. At the same time, the phases of current transformer
and input voltage must correct. Otherwise, the current of collecting and active power maybe not
correct.
NOTE: ICOM port must be connected to negative pole of battery.
