INSTALLATION
13.1
CLIPS
Controller is panel built-in design; and it is fixed by clips for installation.
—
Withdraw the fixing clip screws (anticlockwise) until they reach proper position;
—
Pull the fixing clips backwards (towards the back of the module) and ensure two clips are
inside their allotted slots;
—
Turn the fixing clip screws clockwise steady until they are fixed on the panel.
NOTE:
Care should be taken not to over tighten the screws of the fixing clips.

BATTERY VOLTAGE INPUT:
ACC4100 controller can suit battery voltage environment of DC
(8~35)V. Negative of battery must be connected with the engine shell. Diameter of wire which
connects power supply B+ and B- with battery positive and negative must be over 1.5mm
2
. If
floating charger is configured, please firstly connect output wires of the 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;
—
SPEED SENSOR INPUT:
Speed sensor is the magnetic equipment installed in the starter for
detecting flywheel teeth. The connection wires with controller should apply 2-core shielding line.
The shielding layer should be connected to No. 28 terminal in the controller and another side is
hanging up in the air. The other two signal wires are connected to No. 28 and No. 29 terminals. The
output voltage of speed sensor should be within AC (1~24)V (effective value) during the full speed
range. AC12V is recommended (at rated speed). When speed sensor is installed, let the sensor
spun to contacting flywheel first, then, port out 1/3 lap, and lock the nuts of sensor at last;

OUTPUT AND EXPAND RELAYS:
All controller outputs are relay contact output type. If expansion
relay is needed, please add freewheel diode to both ends of expansion relay’s coils (when relay
coils have DC current) or, increase resistance-capacitance return circuit (when relay coils have AC
current), in order to prevent disturbance to the controller or other equipment.
