reliably connected to engine shell. The connection between controller power and battery should not be
less than 2.5mm

. If a float charger is fitted, please connect output line of the charger with battery
directly, and then connect battery positive and negative to power input of controller separately, in case
that charger will interfere with the normal running of controller.
1)
Speed Sensor Input
Speed sensor is the magnetic device installed in the engine body for testing flywheel teeth. The
connection with controller uses 2-core shieling line, shield layer should be connected to terminal 27 of
controller and the other end vacant. The other two signal lines are respectively connected to terminal
26 and terminal 27. At full speed, output voltage range is (1~24)VAC (RMS), 12VAC is recommended
(rated speed). During installing, make the speed sensor contact the flywheel firstly, then pour out 1/3
laps, finally lock nut on the sensor.
2)
AC Input
HGMS62 controller must externally connect to current transformer; CT secondary current must be
5A. Besides, the phase of CT and input voltage must be correct, or the sampling current and active
power may be incorrect.
NOTE:
Icom must connect to battery cathode of the controller.
WARNING:
When there is load current, open circuit is inhibited in the CT secondary side.
3)
Withstand Voltage Test
When the controller has been installed in the control panel, during the test please disconnect all
the terminals, in case high voltage damages the controller.
