Sequence of Operation
The recommended sequence of operation for a lift-rotate unit is described below.
For 90° rotation
1. Ensure the “Rotate Complete”
proximity switch is activated. This
indicates the lift-rotate unit is in the
“Home” position.
2. Ensure the “Lift Lowered” proximity
switch is activated. This indicates the
lift-rotate unit is lowered and ready
to load a pallet.
3. Release a pallet from the pre-stop
and wait for the “Pallet Present”
above lift unit proximity switch (cus-
tomer supplied) to activate.
4. Lift the pallet by actuating the lift cyl-
inder. The pneumatic solenoid valve
(Fig. 4) is customer supplied.
5. Wait for the “Lift Raised” proximity
switch to activate. This indicates the
pallet is raised.
6. Start the rotate cycle by sending a
0.3 second start signal from your
controller to enable relay CR1 (Ro-
tate Start) in the lift-rotate unit control
enclosure.
7. Wait for the “Rotate Complete” prox-
imity switch to activate, indicating the
unit has stopped rotation.
8. Lower the pallet by actuating the lift
cylinder.
9. Wait for the “Lift Lowered” proximity
switch to activate, indicating the unit
has returned to lowered position.
10. Cycle complete.
For 180° rotation
For 180° rotation, repeat steps 6 & 7 in the
above sequence. Note that the planetary
gearmotor will rotate 360° for each 90°
rotation of the pallet lift plate.
Installation
Mounting the equipment to the trans-
port line
1 Mount the lift-rotate unit to the bottom
T-Slots of the TSplus conveyor sec-
tion using the T-bolts supplied with
the mounting plate. (Fig. 2).

2 Mount the control enclosure to the
outside T-slot of the TSplus conveyor
section using the T-bolts supplied
with the enclosure. Position the en-
closure within 1.5 meters (59”) of the
lift-rotate unit to allow interconnection
of the control cables.
