A
uxiliary Switches
The M9216-xxC models have built-in auxiliary switches
which can be set for any angle between 0 and 90°
(factory set for 10 and 80°) using either an input signal
or the manual crank. (Refer to the
Specifications
section for auxiliary switch ratings.)
The following procedures serve as examples to
change the position of the auxiliary switch angles.
Adjusting Switch Cam S1
To change the angle of Switch Cam S1 to 20°:
1. Insert the manual crank into the manual override
gear.
2. Push in and turn the manual crank CW. Using the
0 to 90° nodule guides, rotate the coupler until the
position indicator is at 20°.
3. Rotate Switch Cam S1 CCW, aligning the edge of
the switch cam with the switch plunger until the
plunger rises. (See Figure 14.)
