General check on angle position can be done as following :
Telescope retracted, horizontal boom : --> SQ533=ON & SQ531=OFF & SQ590=OFF & SQ591=OFF
Extend the boom (nearly 1m) :
--> SQ533=ON & SQ531=OFF & SQ590= & SQ590=
Extend the boom (nearly 8m) :
--> SQ533=ON & SQ531= & SQ590=OFF & SQ590=OFF
Extend the boom (nearly 8m+)
--> SQ533= & SQ531=ON & SQ590=OFF & SQ590=OFF
Extend the boom (nearly 8m++) :
--> SQ533=OFF & SQ531= & SQ590=OFF & SQ590=OFF
Extend the boom to high end : --> SQ533=OFF & SQ531=OFF & SQ590=OFF & SQ590=OFF
Retract the boom (nearly 8m++) :
--> SQ533=OFF & SQ531= & SQ590=OFF & SQ590=OFF
Retract the boom (nearly 8m+) :
--> SQ533= & SQ531=ON & SQ590=OFF & SQ590=OFF
Retract the boom (nearly 8m) :
--> SQ533=ON & SQ531= & SQ590=OFF & SQ590=OFF
Retract the boom (nearly 1m) :
--> SQ533=ON & SQ531=OFF & SQ590= & SQ591=
Telescope retracted, boom down : --> SQ533=ON & SQ531=OFF & SQ590=OFF & SQ591=OFF
To erase F07.11 failure if SQ590 and SQ591 are ON: fold the machine, check the position detectors (repair if
one is broken), power OFF the machine and then power ON.
To erase F07.11 failure if SQ590 and SQ591 are OFF: raise the boom to max position, retract the telescope,
fold the machine, 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.
