Installation - Smartgen HGM9510N User Manual

21 INSTALLATION

The controller is panel built-in design; it is fixed by clips when installed.
1) Battery Voltage Input
NOTE: HGM9510N/9530N controller can suit for wide range of battery voltage (8~35) VDC. Battery negative
electrode must be connected with the engine shell stably. The wire area connecting controller power B+/B- with negative
and positive electrodes must be over 2.5mm
charger to battery's positive and negative directly, and then connect wires from battery's positive and negative to
controller's positive and negative input ports separately in order to prevent the charge from disturbing the controller's
normal working.
2) Speed Sensor Input
NOTE: Speed sensor is the magnetic equipment installed in the engine body to detect flywheel teeth number. The
wires used to connect with the controller shall be 2-core shielding wires. The shielding layer shall be connected to No. 18
terminal on the controller, and meanwhile the other terminal shall be hanging in the air. Another two signal wires shall be
connected to No.19 and No.20 terminals on the controller. The output voltage of the speed sensor shall be within (1~24)
VAC (effective value) in the range of full speed and 12VAC is recommended (at rated speed). As to speed sensor
installation, the sensor can firstly be spun to the connection flywheel, then invert 1/3 lap, and finally tighten up the screw
on the sensor.
3) Output and Expand Relays
CAUTION: All controller outputs are relay contact outputs. If the expansion relay is needed, freewheel diode (relay
coil is DC) and resistor and capacitor circuit (relay coil is AC) shall be added to the two ends of the relay coils in order to
prevent disturbing the controller or others equipment.
4) AC Current Input
Controller current input must be connected to outside current transformer. The secondary side current
of the current transformer must be 5A and at the same time current transformer phase and input
voltage phase must be correct, otherwise the collected current and active power maybe not correct.
NOTE: ICOM port must be connected to negative pole of battery.
WARNING! When there is load current, transformer's secondary side is prohibited open circuit.
