4,4
HPD/Sequencing Fault
Shutdown Throttle
•
The keyswitch, interlock,
direction, and throttle
switches were not applied
in the correct order.
• Faulty wiring, crimps, or
switches for the keyswitch,
interlock, direction
switches, or throttle.
• Moisture in the keyswitch,
interlock, direction
switches, or throttle.
The controller detected that
the keyswitch, interlock,
direction, and throttle switches
were not cycled in the correct
order after an HPD action.

Cycle the switches in the
correct order.

If that doesn’t clear the
fault, check the wiring and
for moisture, then cycle the
switches in the correct
order.
4,9 BB Wiring Fault
Shutdown Throttle
Shutdown EM-Brake
Shutdown Main Contactor
Bad crimps or faulty wiring for
the emergency reverse normally
open switch.
The wire connecting Driver
2 and the emergency reverse
normally open switch is broken.

Fix the wiring, then cycle
the keyswitch.

Emergency braking
Shutdown thumb throttle
Electromagnetic brake shutdown
The inputs for throttle and
forwards and backwards were
not returned to the neutral state
after an emergency braking.
The operator attempted to
drive after an emergency
reverse without first clearing the
throttle, direction, and interlock
inputs.

If the EMR Dir Interlock
parameter’s value is On,
clear the interlock, throttle,
and direction inputs.
Otherwise, clear the
throttle and direction
inputs.
5,2 Parameter Change Fault
Shutdown Motor
Shutdown Main Contactor
Shutdown EM-Brake
Shutdown Throttle
A parameter was changed but
the keyswitch was not cycled.
A parameter that requires the
keyswitch to be cycled has
changed.
 Cycle the keyswitch.
