5. Current Production adjustment procedure:
NOTE: The angle sensor and printed circuit board are a
matched set. The zero adjustment potentiometer
on the printed circuit board must not be re-
adjusted.
It is recommended two people perform this
adjustment procedure.
a. When replacing the angle sensor and printed circuit
board, remove batteries and install the new angle
sensor and printed circuit board with the angle
sensor loosely mounted for adjustment rotation.
Mount angle sensor in position shown.
b. Install batteries.
c. Adjust the block level controller assembly box as
needed such that box mounting surface (backside)
is 90 degrees to the horizontal mounting surface of
the load block assembly.
d. Turn cab power on and scroll to the Level screen for
the block level sensor and block level angle
diagnostic display readings (see Section 3, Crane
Diagnostics, Block Level Sensor topic).
e. While one person is monitoring the block level
diagnostic display in the operator cab, the second
person rotates the angle sensor in the block level
controller assembly until 0 degrees is achieved on
display screen.
f. Carefully tighten angle sensor mounting hardware.
g. Confirm angle sensor reading on diagnostic display
remains 0 degrees.
h. Close block level controller assembly cover
ensuring proper seal and fasten screws (2 each).
Six Lithium type size D batteries are recommended for
longer battery life.
