Boom Angle

D 1
Voltage failure of SQ520 sensor
--> SQ520 > 6.00V
F07.04
Boom Angle
SQ521/SQ523
General check on angle position can be done as following :
Telescope retracted, boom down
Raise the boom to nearly 10deg
Raise the boom (nearly 50deg)
Raise the boom (nearly 50deg+)
Raise the boom (nearly 50deg++)
Raise the boom to high end
Descent the boom (nearly 50deg++)
Descent the boom (nearly 50deg+)
Descent the boom (nearly 50deg)
Descent the boom (nearly 10deg)
Telescope retracted, boom down
To erase F07.04 failure: fold the machine completely (boom telescope, then arm and boom), check the
position detectors (repair if one is broken), power OFF the machine and then power ON.
If failure is still active then one of the six detectors defining the machine position is not in the expected
state.
