Primary Boom Angle Sensor
The primary boom angle sensor works in
conjunction with the boom extend limit switches,
maintaining the working envelope. The primary
boom angle sensor is located underneath the
swing chassis between the timing link arms.
How to Replace the Primary
Boom Angle Sensor
1 From the ground controls lower the primary
boom to the stowed position and then rotate
the swing chassis so that it is perpendicular to
the drive chassis.
2 Push in the red Emergency Stop button at the
ground controls and turn the key switch to the
off position.
3 Locate the primary boom angle sensor under
the swing chassis, between the timing link.
Remove the cover to gain access to the
sensor.
4 Locate and disconnect the angle sensor
harness connector.
5 Remove the angle sensor mounting bracket
retaining fasteners and set aside to be reused.
Remove the angle sensor and bracket
assembly.
6 Remove the angle sensor from the mounting
bracket and install the new angle sensor using
the same fasteners.
7 Referring to the illustration, hold the angle
sensor/bracket assembly at an angle away
from the mounting plate and match up the hex
shaft to the sensor. Rotate the assembly
towards the mounting plate and install the
angle sensor assembly to the mounting plate
using the fasteners removed in step 5. Do not
completely tighten at this time.
Note: This will index the sensor to obtain the
required voltage to allow calibration.
