Pneumatic cylinder
adjustments
Cycle the air cylinder to raise and lower the
lift plate. Check and adjust the lift speed
by turning the flow controls in the top and
bottom port of the cylinder (see page 9
Fig. 4). The bottom port controls the lift and
the top port controls the lowering of the
cylinder. Turn the screw clockwise to slow
down cylinder travel or counterclockwise to
speed it up. Adjust both the up and down
travel speed to best suit your application.
End cushion adjustments
NOTE: The end cushions are preset
and usually require no adjustment.
Adjust the end cushions only if a softer
or harder stop is required at the end of
the cylinder stroke.
Using a hex key wrench adjust the end
cushions at the top and bottom of the lift
cylinder, (next to the flow controls). Turn
the valve clockwise to give the cylinder
a softer stop, or counterclockwise for a
harder stop.
Switch adjustments (Fig. 6)
Adjust the three (3) proximity switches
mounted on the unit so that there is 0.5 mm
gap (Fig. 6) between the end of the switch
and switch exciter. Adjust the lift raised and
lift lowered switches by loosening the jam
nuts on the switch body. Adjust the rotate
complete switch by loosening the phillips
head screws on the switch clamp. Reposi-
tion the switch by sliding it in or out of the
clamp; then retighten the clamp screws.
Start push-button
CAUTION! Before using the
START feature, raise the lift plate by
supplying air to the lift port of the air
cylinder (see page 9, Fig. 4 ). Press-
ing the START push-button with the
lift-plate in the lowered position will
damage the rotate mechanism.
Raise the lift plate and push the start button
(Fig. 12) to manually rotate the unit. When
the button is pushed, the controller causes
the pallet plate to make one 90° rotation.
This will be one 360° rotation of the rotate
cycle cam. The start push-button can also
be used to drive the rotate unit to its home
position if the rotate unit is interrupted dur-
ing the rotate part of its sequence. Rotate
speed should be as slow as possible to
provide maximum module life.
Rotate speed control
Turn the rotate speed control P1 in the
electrical enclosure to its center of ro-
tation. Push the start button to check
rotational speed. If required, the speed
can be changed by turning the control P1
clockwise to speed up rotation of the lift
plate or counterclockwise to slow it down.
Experiment with the speed control and
set it to fit your application. Do not set the
speed control so fast that the payload on
the pallet shifts as the pallet rotates. Rotate
speed should be as slow as possible to
provide maximum module life
