SWITCHES
See Figure 4-35., Boom Sensor Locations - Dual Capacity,
Length, & Main Boom Transport and Figure 4-44., Main
Boom Transport Length Switch Wiring
The Transport Length Switches are located on the right
side of the Main Base boom underneath the cover. These
switches run on cams mounted to the upper fly boom to
determine if the main boom is telescoped within or
beyond the transport position. They also work with the
Dual Capacity Switches to determine the length of the
main boom to restrict the main boom length between the
main boom angles of +55° and -45° for the 1000 lb (450
kg) envelope.
Analyzer Readings
The analyzer reading for these switches can be found in
