INSTALLATION
The installation dimension of
HGM8110A
is just the same with
HGM8120A.
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,
Fig.8 Overall and Cutout Dimensions
12.1
BATTERY VOLTAGE INPUT
NOTE:
HGM8110A/8120A 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 2.5mm
2
.
If floating charger 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.
12.2
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 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 (at 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.
12.3
OUTPUT AND EXPAND RELAYS
CAUTION:
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, add resistance-capacitance return
circuit (when coils of relay have AC current), in order to prevent disturbance to controller or others equipment.
12.4
AC INPUT
Current input of HGM8110A/8120A controller must be connected to outside current transformer. And
