HGM93XX MPU(CAN) Series Genset Controller Version: 1.1 2016-11-03 Page 63 of 77
13 INSTALLATION
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,
1)
Battery Voltage Input
NOTE:
HGM93XXMPU(CAN) series 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 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
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 (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 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
has DC current) or, increase resistance-capacitance return circuit (when coils of relay has AC
