CAUTION
Throttle Parameters
It is strongly recommended that the throttle type and
direction parameters be adjusted only when the controller
is in a bench test setup. Changing these parameters while the
controller is installed in the vehicle could result in vehicle
runaway. If, for example, the throttle is a wigwag and the
throttle type parameter is changed from wigwag to single-
ended, the vehicle will register a throttle input and begin to
move without any operator control. If it is necessary to adjust
the throttle parameters with the controller in the vehicle, the
vehicle drive wheels should be jacked up until the mechanical
throttle, the programmed throttle type, and the programmed
direction type all match.
THROTTLE TYPE [default access: OEM]
The controller can be programmed to accept single-ended, wigwag, or inverted
wigwag signals from a 5kΩ, 3-wire pot or from a 0–5V voltage source. These
throttle styles are described in Table 2 (page 19).
The throttle input signal type options—Types “0” through “3” in the
Throttle Type programming menu—are listed in Table 4.
