12.2 OVERALL DIMENSION AND PANEL CUTOUT
1) Battery Voltage Input
HGM6100U
series controller can be applicable to (8~35) VDC battery voltage.
Battery negative must be reliably connected to engine shell. The connection
between controller power and battery should not be less than 2.5mm
2
. 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.
2) Speed Sensor Input
Speed sensor is installed in the engine for testing flywheel teeth. The connection
with controller uses 2-core screen, shield layer should be connected to terminal16
of controller and the other end vacant. The other two signal lines are respectively
connected to terminal15 and terminal16. 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.
3) Output And Expansion Relay
All the outputs of controller are relay output. If need to expand relay, please add
freewheeling diode in both ends of relay coil (when expansion relay coil links DC),
or add RC loop (when expansion relay coil links AC), in case controller or other
equipments are interfered.
4) AC Input
HGM6100U series 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.
