Smartgen HGM400 Series User Manual page 43

HGM400 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 1.5mm
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
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. 1 terminal in controller
while another side is hanging in air. The else two signal wires are connected to
No.1 and No.17 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 Expansion Relay
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.
4) AC Input
HGM400 series controller must be connected to outside current transformer. And
the current transformer's secondary side current must be 5A. At the same time,
the phases of current transformer and input voltage must correct. Otherwise, the
collected current and active power maybe not correct.
CAUTION！ICOM port must be connected to negative pole of battery.
WARNING! When there is load current, transformer's secondary side prohibit
open circuit.
5) Withdraw Voltage Test
When controller had been installed in control panel, if need the high voltage test,
