of range if it is congured
as a voltage input or may
include potentiometer faults if
congured as a 2/3-wire pot.

1. Incorrect sequence in application
of Keyswitch, Interlock, Direction,

2. Faulty wiring, crimps, or switches at
KSI, Interlock, Direction, or Throttle.
3. Moisture in above-noted digital
input switches causing invalid (real)
On/Off state.
4. Verify input switch status. See

have not been returned to neutral.
Set: At the conclusion of
Emergency Reverse, the fault
was set because various inputs
were not returned to neutral.
Clear: If EMR_Interlock = On,
clear the interlock, throttle, and
direction inputs.
If EMR_Interlock = Off, clear
the throttle and direction inputs.
