Controller Wiring Diagram (Examples)

The basic wiring diagrams for a Class III pallet truck use wired inputs from switches and
potentiometers, driving the traction motor. The Interlock, Forward, Reverse, Lift, Lower, and the
redundant Emergency Reverse inputs are by external mechanical switches pulled to KSI (B+).
Quick Links: The traction motor feedback shall match the motor technology. The throttle input is a 3-wire
Appendix E p.262
potentiometer (which meets EEC fault protection). Beyond these assigned I/O usages, the available
(non-assigned) switch inputs, drivers, and the analog output, are programmable to suit a diverse
range of the controller applications.
The F4/6-A illustrates both the non-isolated and isolated CAN port options. See Appendix E for
the controller models and specifications, which support these options. The F2-A does not offer an
isolated CAN port option.
