Pallet Master - PMD 25, 35, 50 & 100

High Speed

POWER

The system is designed to operate on 120 VAC 50/60 HZ power. The unit is provided with a
power cord that distributes the power to a terminal strip located under the pallet reel dial plate.
The power is then distributed to the proper control panel. The distributed power is circuit
breaker protected and is intended as a power source for the Pallet Reel and any additional
Rapid-Air accessory. Simply plug the main power cord into any grounded 120 VAC recepta­cle.

EMERGENCY STOP & POWER MONITOR INTERFACE

The system provides a control relay for emergency stop and power monitoring. These are con­trols provided to the user as an optional interface. If the user does not require or desire these
features the system is operational as received from the factory.

An isolated form “C” contact arrangement is provided for customer interface to monitor
“emergency stop” or “taut stock” detection. The contact is terminated on the base terminal
block (ref. Fig. RA-4/RA5) pin out is N.O. term-10; N.C. term-11; common term-12. The con­tacts are rated at .5 amps at 28 VDC.

SETUP & INSTALLATION

Determine the direction and rotation that the material shall decoil as it leaves the PMD. Posi­tion the PMD as close as possible to the end of the press.

Install the control arm assembly in the control head hub such that the counter weight is pointing
toward the turntable. Position the control head and arm then lock in the appropriate exit side of
the PMD.

The following sketches will show the four basic decoiling arrangements. The choice depends
upon such factors as weight, geometry of the material, C.W., or C.C.W. decoiling and available
floor space.

Pre-Operation Check

Before placing any material on the turntable ensure that all functions are in the correct mode for
machine operation. i.e.

1. Switch “OFF”

2. Run/Stop/Jog “stop” position.

3. Control arm arranged with counter weight toward the turntable at its max. extension.

4. Lock the control head.

5. Rotation directions switch to agree with the decoiling direction of the material on the pallet
that is ready to be loaded onto the PMD.

6. Loop range at maximum 3”.

7. Loop height—0.

8. Stock direction switch located just under the control arm pivot, switch to direction of mate­rial flow to the press.

Start up and Run Check

9. Switch “ON”.

10. Run / Stop / Jog - “RUN”

11. Slowly push (rotate) the control arm toward the turntable to start the rotation.

(a) If the table turns in the wrong direction, reverse rotation direction switch.
(b) The turntable speed should increase as the control arm is moved toward the table.
If otherwise. Reverse the stock direction switch.

Operation

12. Place the coiled stock on the turntable. Center the material on the turntable within 1/2 inch
from center.

13. Rotate the table slowly by pushing the control arm toward the turntable. Unwind the first
coil until the material can be threaded around the roller and back toward the press. The con­trol arm and turntable will, now, operate automatically.

14. Slowly walk the material to the press. An alternate means of moving the material toward
the press is the Run/Stop/Jog switch in repetitive Jog actuations. This may be a preferred
method since this function overrides the control arm that may not be properly set at this
time.

15. Run/ Stop/ Jog - “STOP”

16. Adjust the roller angle so that the material makes full contact.

17. Adjust the height of the control arm.

18. Adjust the counter weight to just offset the affect of the material loop so that the control arm
will go back to the starting (rest) position when the press is not demanding material. (Refer
to Inst #24 for loop height.)

Control Adjustments

19. Run/Stop/Jog: (see inst. #14)

20. Rotation directions: (see inst. #5)

21. Loop Range: This switch selects the sensitivity of the control arm travel from minimum to
maximum speed in a narrow to a wide range depending upon the arm length of the control
arm and press material demand.

22. Loop Height: This switch sets the start position in the arc of the control arm as it swings off
of its mechanical stop.

(see dia. next page)

Electronic loop height adjustment

Eight different loop sensing arm operating positions are
selected manually during set-up. In operation, the desired
position is monitored and maintained electronically. Each
separate position will move the operating angle of the arm
so that top-to-bottom travel is located to accommodate
specific material and loop height requirements.

Loop sensing arm operating range

30º- Loop sensing arm travels through a
full 30º arc to vary turntable rotation speed
from slow to full speed.

20º - Travel through a 20º arc changes
rotation speed from slow to full speed.

10º - Slow to full speed varies as the loop
sensing arm travels in a 10º arc.

5º - Only the first 5º of loop sensing arm
travel is required to control turntable
rotation from slow through full speed.

Instruction for wiring Pallet Master Decoiler after shipping

1. See drawing (fig RA-1)

2. Feed wires from base through hole in control arm.

3. Bolt control assembly to base with (4) 1/2-13 x 3/4 screws provided.

4. Take off control sub-panel access cover by removing (14) screws.

5. See drawing (fig RA-4) for 230 V system

See drawing (fig RA-5) for 110 V system

6. Connect wiring shown on drawing (fig RA-4) or (fig RA-5) which ever applies.

7. Replace cover.
