11 INSTALLATION
Controller is panel built-in design; it is fixed by clips when installed.
1) Battery Voltage Input
NOTE: APC715 controller can suit for widely range of battery voltage
DC(8~35)V. Negative of battery must be connected with the engine shell soundly.
The diameter of wire which from power supply to battery must be over 2.5mm
2
. 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 corresponding input ports in order to prevent charge
disturbing the controller’s normal working.
2) Speed Sensor Input
NOTE: 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 shielding GND
terminal in controller while another side is hanging in air. The else two signal wires
are connected to MP1 and MP2 terminals, moreover, MP2 has already connected
to B- innerly. 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
NOTE: 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.
