Adjusting the 90
o
Proximity Switch
Before delivery of a new INFLEXION, all switches are properly set and tested and normally no switch adjustment is
necessary. However, if the 90
o
switch needs adjusted, like after the actuator was replaced, follow these steps to adjust
the 90
o
switch:
1. Make certain that the INFLEXION base is level.
2. Remove the base side cover.
3.
Loosen the upper jam nut to lower the switch approximately 1/8”.
4. Raise the mast to 90
o
by holding the “Mast Up” button until the mast is at 90
o
.
5. Check that the mast is at 90
o
by using a level and also ensuring that the mast is square to the
sheet metal side plate on the base. A value in the range of 89.5
o
to 90.5
o
is acceptable.
6. Raise the 90
o
switch until it senses the actuator. This will be indicated by the status LED on the
base circuit board (Figure 4-2).
7. Secure the switch in position using the upper and lower jam nuts.
8. Raise and lower the mast several times, checking that the mast is plumb each time and adjust the
switch if necessary.
9. Replace the cover.
Adjusting the Stow Proximity Switch
Before delivery of a new INFLEXION, all switches are properly set and tested and normally no switch adjustment is
necessary. However, if the stow switch needs adjusted, like after the actuator was replaced, follow these steps to adjust
the stow switch:
1. Make certain that the INFLEXION base is level.
2. Remove the base side cover.
3. Loosen the upper jam nut to lower the
switch approximately 1/8”.
4. Raise the mast to 90
o
by holding the “Mast Up” button until the mast is at 90
o
.
5.
Hold the “Mast Down” button until the mast stows firmly into the saddle then release the “Mast
Down” button.
6. With the mast stowed, carefully grasp the payload and attempt to slowly lift the payload off the
saddle. If the saddle is not snug into the saddle, repeat steps 4 through 6 until the mast is firmly
in the saddle.
7. Secure the switch in position using the upper and lower jam nuts.
