Solution
Determine why messages are not
being received. When problem is
corrected the alarm will clear
Get temperature into acceptable
range and alarm will clear after 1
minute
Cycle power to receiver. If
problem continues. Find what
caused the overcurrent draw and
cycle power.
Determine the cause of the short.
Fix the cause and cycle power to
the receiver
Determine the cause of the short.
Fix the cause and cycle power to
the receiver
Hoist down load if applicalble.
Raise boom off any supports.
Alarm will clear once pressure in
cylinder is restored.
Rotate ccw to clear the error.
Once the switch is deactivated
the alarm will clear.
Rotate cw to clear the error.
Once the switch is deactivated
the alarm will clear.
Move vehicle to level ground
Move vehicle to level ground
Move load away from the boom
by either retracting, hoisting
down, or booming up. If there is
no load near the tip of the boom
check function of the bail
weldment, it must come into
contact with the switch plunger
under normal conditions
Reduce load to clear the alarm
Reduce the load by retracting the
boom, lowering the boo, or
raising the boom.
This is a safety feature that
prevents excessive swinging of
heavy loads. It will reset when
the load decreases and function
is deactivated.
Check connections to boom
angle sensor. Verify lights are on
at sensor base.
Boom angle sensor is mounted
incorrectly. Check the mounting.
The arrow should be facing the
tip of the crane.
Check connections to pressure
transducer located on the lift
cylinder. Check the wiring
harness for damage
Replace filter. Part number is
