12 INSTALLATION
12.1 FIXING CLIPS
— The module is held into the panel fascia using the supplied fixing clips.
— Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
— Pull the fixing clip backwards (towards the back of the module) ensuring four clips are inside their
allotted slots.
— Turn the fixing clip screws clockwise until they make contact with the panel.
NOTE: Care should be taken not to over tighten the screws of fixing clips.
12.2 OVERALL DIMENSION AND PANEL CUTOUT
Fig.9 – Case and Overall Dimensions
HGM6100LT 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 (B+ and B-) and
battery (B+ and B-) should not be less than 2.5mm
2
. If a floating 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 installed in the engine for testing flywheel teeth. The connection with controller
uses 2-core screen, shield layer should be connected to terminal 16 of controller and the other end
vacant. The other two signal lines are respectively connected to terminal 15 and terminal 16. 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) 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 interfering controller or other equipment.
3) AC Input
HGM6100LT 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.
