Warning!!!

Taut Stock (over travel reset) not connected.

Check wiring schematic to connect interface with material pulling device.

INSTALLATION

1. The machine that you have just received is fully assembled and ready to be put into posi­tion. Due to shipment vibration the machine should be checked to be sure all screws and
bolts are tight and that all electrical components are in place inside cabinet. Visually in­spect the machine for damaged parts due to shipment. If the machine was damaged in ship­ment, contact the carrier first to report the damage, and then Rapid-Air.

2. Install the machine on a level surface with sufficient clearance for loading and unloading
coils.

3. The machine is completely self-contained and need only be plugged into a 20 amp, 120 volt,
60 HZ outlet. If an extension cord is used as the source to the machine, it should be a mini­mum #12 gauge wire to keep the voltage loss down and for electrical safety reasons.

The main control unit is located behind the pushbutton cover. Below is an illustration of the
layout of the control panel. This diagram lists all the components and the approximate location
of each that could be used for troubleshooting the machine if a problem should occur. The reel
is shipped with—120 VAC (1 phase) input. Visually check all electrics before starting the reel.

Mechanical Operating Procedure

To Load or Unload a Coil Ring

The PMD can handle any coils that are on a pallet, table diameter is 42 inches for the PMD-35
and 51 inches for the PMD-50 and max 3500 lbs on a PMD-35 and MAX 5000 lbs on a PMD
50, but only up to 30 inches in height from the table top.

Step 1:

Decide if the material that is paying out will go over the table or beside the table and which side
of the table. If all the coils are wrapped the same way then choose a side that will be in line
with the press and don’t forget the ease of loading of the pallets. If the coils are wrapped so the
table direction has to be switched to unwind the next coil then over the top will be best other­wise the PMD will have to be moved to pay off the other side as the material flow is the oppo­site way.

Step 2:

Make sure the arm is clear of the loading zone and load the pallet onto the table. Align the pal­let so it is in the center of the table. Adjust the dancer arm roller assembly so that it is even
with or slightly above the coil that is being unwound. Jog the table around so the end is within
reach from the operator station and stop. Cut the material free and grab the loose end and then
jog the table around so the material can be threaded in behind the roller. When there is suffi­cient material available, the PMD can be put into “run” and as the material is walked to the ma­terial work station the PMD will rotate and keep up.

Setting up the control

Turn on the main power switch and select “LH” for loop arm horizontal at “Loop Type” on
the pushbuttons.

Turn off the main power switch, press and hold the “Run/Stop/Jog” button while turning the
main power switch on. The first screen you see will display the jog speed percentage.
_________________________________
| JOG SPEED 23% + |
| NEXT - |
|_________________________________|

If you want the jog speed faster then press the “Reel Speed “+ “ “ pushbutton. If you want
the jog speed slower then press the “ Reel Speed “-” “ pushbutton. The jog speed is shown
in percent of max jog speed. If the jog speed is “OK “ then push the Run/Stop/Jog button
once for next.

The next screen asks if you want to set up the sensor? As before the percent speed buttons
are used for the yes-no. Select “yes”! And then next.
_________________________________
| SETUP SENSOR YES |
| NEXT NO |
|_________________________________|

The next screen asks you to set the low set point. If the dancer arm is at “No Material
Rest” then just save the setting by pushing the Stop/Run Jog pushbutton.
_________________________________
| SENSOR LOW SETPOINT |
| SAVE XXX |
|_________________________________|

The next screen is to set the offset of the program. Potentiometers are hard to get set from
left to right so we built in an offset. If you set the low and high range and go into run and
the reel runs for no reason then an offset has to be put in. Go through the setup procedure
again and put in an offset of –3 to –5 and now the pot is zero.

_________________________________
| LOW OFFSET +0 + |
| NEXT - |
|_________________________________|

5

You have now set the dancer arm limits.
The next screen is to exit the setup and start working.
_________________________________
| EXIT SETUP? YES |
| NO |
|_________________________________|

Choose yes and next and the next screen appears.

_________________________________
| SHUT OFF POWER TO |
| SAVE AND EXIT |
|_________________________________|

The dancer arm is now ready for production running.

DANCER ARM LOOP POSITION ADJUSTMENT

Eight different loop sensing arm operating positions can be selected during set-up. The mate­rial thickness determines the dancer arm rest position. Once the material is threaded up and
the material is resting on the dancer arm and the reel runs in the rest position then select a
higher number on the height adjustment until the reel stops rotating. The zero point of the
dancer arm is moved from it’s no material rest position to the current rest position shown (as
indicated 0-8). The dancer arm will start the material dereeling from the new rest position se­lected. The function is active and can be changed in the run mode.

DANCER ARM LOOP RANGE FUNCTION

The loop range function selects the degree of arm movement to achieve maximum motor
speed selected. If a loop range of “0” was selected then the arm would only have to move ap­proximately 1/2 inch to have the reel at full speed whereas if the loop range “8” was selected
then the arm would have to move almost the full travel or approximately 41/2 inches to get to
full speed. The function is active and can be changed in the run mode.
