Activates the axle oscillate circuit on the right side.
LSA2OS: Limit switch, Axle #2 Oscillating Operational.
Activates the axle oscillate circuit on the left side.
LST1O: Limit switch, Operational. Activates the drive enable
zone.
Turntable Angle Sensor: Measures the X axis and Y axis of
the turntable. The alarm sounds at 4.5 degrees.
Primary Boom Angle Sensor (PBS): Measures the Y axis
angle of the primary boom. The operational range shall be +33
degrees to +73 degrees. The safety cutouts are set at +70
degrees and will disable boom up and stop the engine.
Platform Angle Sensor: Measures the angle of the platform.
The range of measurement is +/- 20 degrees. The safety cutout
is set at +/- 10 degrees from gravity and will disable the primary
and secondary boom up/down functions and the platform level
up/down functions.
LSS2AO: Limit switch, Secondary Boom #2 Angle Operational
Switch. Secondary boom angle full extension, angle up all the
way (secondary boom extend allowed).
LSS3AO: Limit switch, Secondary Boom #3 Angle Operational
Switch. Secondary boom elevated to 30-35 degrees. Used to
switch platform/primary boom leveling parameters.
LSS2AS: Limit switch, Secondary Boom #2 Angle Safety
Switch. Secondary boom angle full extension, angle up all the
way (secondary boom extend allowed).

LSS1RO: Limit switch, Secondary Boom #1 Retract
Operational Switch. Secondary boom fully retracted
(secondary boom down allowed).
LSS1RS: Limit switch, Secondary Boom #1 Retract Safety
Switch. Secondary boom fully retracted
(secondary boom down allowed). Backup switch for LSS1RO.
LSS1AO: Limit switch, Secondary Boom #1 Angle Operational
Switch. Open when the secondary boom is fully lowered, closes
when the boom is raised out of the stowed position. This switch
limits the drive speed and disables the drive motor destroke.
The other contacts close when the boom is fully lowered
allowing the platform to be tucked underneath the mast for
transport.
LSP1AO: Limit Switch, Primary Boom #1 Angle Operational.
One side closes when the primary boom is raised from the
stowed position, disabling the drive motor destroke and limiting
the drive speed. The other side of the switch closes when the
boom is fully lowered allowing the platform to be tucked
underneath the mast for transport.
LSJ1EO: Limit Switch, Jib Boom #1. Closes when the platform
leveling cylinder is fully extended, disabling the primary boom
down function.
LSP1EO: Limit Switch, Primary Boom #1 Extend Operational.
Switch closes as the primary boom extends the last 6 to 12
inches signaling the computer.
LSP1RO: Limit Switch, Primary Boom #1 Retract Operational.
Switch closes when the primary boom is fully retracted.
