WIRING: Pedal Switch
When the Pedal Switch option is enabled, controller output is possible only when
the pedal input (Pin 8) is pulled to B+. This feature allows a switch connected to
the throttle mechanism to guarantee zero controller output when the operator
releases the throttle. This adds a safety feature to protect against throttle failures
that cause controller output when the throttle is in neutral.
Alternatively, the pedal input can be wired into the brake pedal circuit to
automatically force zero controller output when the brake pedal is depressed,
regardless of throttle request.
WIRING: Hour Meter
The hour meter output (Pin 12) pulls to B+ to enable an hour meter whenever
current is flowing in the motor. This allows accurate accumulation of vehicle
operating hours. The output is current limited to 20 mA, and is compatible with
Curtis 700 and 800 series hour meters. For wiring, consult the documentation
supplied with the hour meter.
WIRING: CAN Bus Interface
Refer to the Curtis CAN Protocol Document for information about the CAN
Bus interface.
WIRING: Emergency Reverse
If you are installing a 1244 controller in a walkie vehicle, the emergency reverse
switch should be wired to Pin 7, as shown in Figure 13.
