Boom Stowing Light
The Boom Stowing Light turns on to indicate the
boom is stowed.
The Boom Stowing Light changes between a
steady green, steady yellow, and flashing red,
depending on which of the following two storage
positions are detected:
The light flashes red when neither of the two
stowage positions are detected.
The light is steady yellow if only the slewing
stowage position is detected.
The outrigger is determined to be stowed once
both detection positions are simultaneously
detected and the Boom Stowing Light illuminates
in green.

Determined as stowed once the boom stops at the
slewing stowage position.
Boom movement is detected by interactions
between the depression (2) on the post (slewing
side) and the detector switch (1) on the travel
undercarriage (fixed side).
