Rotate cycle cam adjustments
(Fig. 7 & 8)
The rotation cycle cam is used to adjust
the stopping position of the unit. When the
rotate home limit switch rolls back up onto
the cam, the unit will stop. Depending on
rotation speed and load, a varying amount
of “dwell” will be required for the unit to
come to a stop after the limit switch has
engaged the cam.
The amount of dwell on the rotation cycle
cam is pre-set at the factory for a nominal
“home” position based on a clockwise
direction, full-speed rotation, and no load.
However, some final adjustment will be
required once the unit is installed. The
amount of adjustment will vary depending
on the load and speed of rotation. Also, the
direction of rotation will change the orienta-
tion of the cam (see Fig. 7 & 8).
Adjust the cam by loosening the set-screw
and rotating the cam on the shaft. The cam
is in position with the proper amount of
dwell once the unit’s rotation cycle ends
with the exciter for the “rotate complete”
proximity switch aligned with the proxim-
ity switch. See the following sections for
specifics on cam orientation for clockwise
and counterclockwise rotation.

Clockwise lift-plate rotation
(Fig. 7)
With the drive motor wired for clockwise
lift-plate rotation, the cam lobe will rotate
counterclockwise. With the Rotate Com-
plete proximity switch in the on position,
loosen the set screw in the rotate cycle
cam and turn it until the Rotate Home
limit switch is just starting the dwell cycle
(Fig. 7). The unit will automatically initiate
another rotate cycle if the cam passes
beyond the dwell area of the Rotate Home
limit switch.
Counterclockwise lift-plate
rotation (Fig. 8)
With the drive motor wired for counter-
clockwise lift-plate rotation, the cam lobe
will rotate clockwise. With the Rotate
Complete proximity switch in the on posi-
tion, loosen the set screw in the rotate
cycle cam and turn it until the Rotate Home
limit switch is just starting the dwell cycle
(Fig. 8). The unit will automatically initiate
another rotate cycle if the cam passes
beyond the dwell area of the Rotate Home
limit switch.
Adjustments
NOTE: Counterclockwise cam lobe rotation
results in clockwise lift plate rotation.
NOTE: Clockwise cam lobe rotation results
in counterclockwise lift-plate rotation.
