Limit Switch Functions
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.
Jib Bell Crank Angle Sensor: Measures the
angle of the jib bell crank. The range of
measurement is + 60 / -70 degrees.
Safety Controller (SCON): Redundant dual axis
tilt sensors measuring the X and Y tilt angles of the
turntable. Also provides safety switch logic for
function cut-off. Alarm sounds at ±4.5 degrees.
Part No. 218700
Limit Switches and Angle Sensors
LSFA1ES: Limit switch, Front Axle #1 Extended
Safety. Prevents boom functions with the axles
retracted. Switch closes when axles are fully
extended.

Safety. Prevents boom functions with the axles
retracted. Switch closes when axles are fully
extended.
LST1O: Limit switch, Turntable #1 Operational.
Activates the drive enable zone when the turntable
is rotated in the left direction.
LST2O: Limit switch, Turntable #2 Operational.
Activates the drive enable zone when the turntable
is rotated in the right direction.
LST1S: Limit switch, Turntable #1 Safety.
Prevents the turntable from rotating out past either
rear tire when axles are retracted.
LSS1RO: Limit switch, Secondary Boom #1
Retracted Operational. NOHC when secondary
boom is fully retracted. Used to reduce turntable
rotate speed when secondary boom is extended
and to disable secondary boom down unitl fully
retracted.

Used to cut circuits P9B, P_11 and P_30.
LSJ1RO: Limit Switch, Jib Boom #1 Retract
Operational. Switch is held closed when the jib
boom fully retracted. Used to limit turntable rotate
speed and drive speed when jib boom is extended.
