Fault Description
Pressure sensor voltage output < 0.4V for
240ms
Pressure sensor voltage output > 4.5V for
240ms
Pressure transducer reads > 3250 psi for 2
seconds while main dump valve energized
and engine is running
Pressure transducer reads < 1500 psi for 2
seconds while main dump valve energized
and engine is running
The model selection has been changed.
Driving is not possible while the vehicle
generator is running AND is configured to
prevent drive.
Boom functions are not possible while the
vehicle is being driven AND is configured to
not allow simultaneous drive & boom oper-
ation.
Driving is not possible while the vehicle
above elevation AND is configured to pre-
vent drive while above elevation.
Driving is not possible while Boom func-
tions are selected AND is configured to not
allow simultaneous drive & boom opera-
tion.
Driving is not possible while the vehicle is
tilted and above elevation AND is config-
ured to prevent drive while tilted and
above elevation.
JIB Swing is not possible while the vehicle is
in 1000 LB Mode.
CAN Dongle attached. Very limited restric-
tions for all hydraulics systems.
The control system has determined that the
platform is leveled under and is being con-
sidered to be in a loading/unloading posi-
tion. Boom, Tower, and Level Override
functions will operate at creep speed.
Sensor output < 0.1V
Sensor output >4.9V
