CONFLICTING
STATES 2558 1 Illuminate the vehicle system
distress indicator in the cabin’s
display.
Activate the buzzer for a period of 5
seconds in the cabin’s display.
Illuminate the vehicle system
distress indicator at the platform
station.
Activate the buzzer for a period of 5
seconds at the platform station.
If a platform is detected as attached
and both AM J1-4 and J7-8 are
LOW and the J3-8 Boom Retracted
input is HIGH.
Power cycled.
BOOM RETRACTED
SENSOR FAULTY –
SENSING INVALID 2560 1 Consider any information on input
J3-8 Boom Retracted invalid.
Set the system as if the boom is
always extended.
The UGM has detected one of the
following failures of the boom
retracted sensor when configured
for LSI-CAN or LSI-CAN + LMI:
With no telescope functions active,
a boom retracted sensor state
changes occur.
With Telescope In active, a boom
retracted sensor transition of HIGH
to LOW occurs.
With Telescope Out active, a boom
retracted sensor transition of LOW
to HIGH occurs.
With Telescope Out active, the
boom retracted sensor has not
HIGH for a period of 5 seconds with
at least 950mA commanded on the
function AND the Load Moment
Warning Point has been met or
exceeded.
Power cycled.

VALVE –
OPEN CIRCUIT 33181 1 Deactivate output J2-11 Main Lift
Up Valve.
The UGM detects an open circuit at
this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.

Deactivate output J2-22 Main Lift
Down Valve.
Decouple/disable current feedback
input J3-2 Lift Return (Disables Lift
Up and Down).
The UGM detects a short to battery
at this output.
Power cycled.

GROUND 33183 1 Deactivate output J2-11 Main Lift
Up Valve.
Decouple/disable current feedback
input J3-2 Lift Return (Disables Lift
Up and Down).
The UGM detects a short to ground
at this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
