Step 1 - Determine the System Orientation
Goal:
Determine the best machine orientation for application. The PA/4600 and PA/6000 are
capable of rotating and pitching about various axes to accommodate a wide range of label
placement opportunities. Select the best orientation from the given measurements and
desired label locations. Keep in mind that if barcodes are to be printed, some feel that rotated
barcodes print the best.

Min=30 in.
Step 2 - Connect Compressed Air and AC Power
Goal:
Provide the unit with clean, dry compressed air and connect the power supply to a noise-free
AC power line.
Note:
The system employs an automatic drain air filter, which will remove most of the condensation
in the incoming pneumatic line. Since the purged water will exit from the bottom of the filter
bowl, it may be desired to add a short hose to the drain valve to route the water to a nearby
floor drain.
Note:
When connecting the AC power outlet, do not use extension cords to power the unit.
Extension cords can reduce the amount of current supplied to the unit and introduce
electrical noise. A dedicated AC line drop is preferred. This eliminates problems caused by
other AC loads on the same line, such as motors, which create back EMF. Disturbances such
as these can cause erratic behavior, system resets, and other anomalies.
Connect the dry compressed air line supplying 60 psi or greater at 2.5 CFM or better to the inlet air
filter/regulator of the system with the OSHA valve closed. Next, connect the AC line to a dedicated
line drop supplying noise-free power. The unit will turn on automatically. Turn on the air valve to the
system by pressing down and turning the valve clockwise, be aware that the tamp cylinder will move
to the home position once air is supplied.

Step 3 - Mount and Adjust the Product Detector
Goal:
Determine which mounting location is ideal, either on the baseplate or on the conveyor
system.
Goal:
Adjust the sensor to detect just the product, and ignore background objects, such as forklift
trucks, personnel, or other objects that may pass in front of the sensor’s view.
•••• Sub-Step (a) ••••
Determine if a product detector mounting location on the baseplate
will work for this application. Typically, the location on the
baseplate is ideal for mounting ease and mobility. This location
works best if the products are approaching from the side of the
sensor, in relation to the tamp pad. If this location cannot apply the
label in the desired position due to timing, mount the sensor in an
alternate location using the supplied mounting bracket.
•••• Sub-Step (b) ••••
Adjust the sensor’s sensitivity to detect just the product, and ignore
the background. This can be done by placing the actual product in
the path of the sensor’s view. Adjust the sensitivity setscrew (A)
until the yellow light (B) illuminates, and the green light (C) is
steady and bright. The yellow light shows that the output is active.
The green light shows the relative signal strength in the presence
of the product. When the sensor is not detecting a product, the
green light is on to show that the sensor is powered on. This can be
useful for troubleshooting and calibration. Remove the product and
verify that the yellow light is off. If not, adjust the setscrew counter-
clockwise to reduce sensitivity. Once the background is eliminated
from triggering the sensor, place the product under the sensor
again to verify output.

Step 4 - Configure the One Time Settings (OTS)
Goal:
Enter the One Time Settings screens and select the configuration of this particular system.
Note:
Most of these items were determined when the unit was assembled; so only configurations
that have changed require this adjustment.
Note:
These selections can only be accessed when the unit is first powered up. This can be done
when the power is first applied, or when the unit is taken out of

Step 7 - Adjust the Inlet Filter / Regulator
Goal:
Apply air to the system, adjust the incoming regulator, and verify air quality
Be certain that nothing is going to interfere with the cylinder extending or retracting, and
apply air line pressure to the system by switching on the OSHA-approved shutoff switch on
the inlet filter/regulator. Adjust the regulator by
lifting up on the knob and rotate counter-
clockwise to increase the system air pressure.
View the pressure setting on the pressure sensor
digital display, located on the air manifold. Set
the pressure between 60 and 100 psi. Once the
correct pressure is set, press down on the knob
to lock it in position. Remove the knob entirely by
lifting it up past the unlock point, if there is
concern about system tampering.

Step 9 - Adjust the Tamp Pad Position
Goal:
Slide the tamp cylinder module across the dovetail track to the correct position in front of the
printer, this will be approximately 1/8th of an inch from the peel blade edge.
Goal:
Align the tamp pad height to the peel blade feed position; this should be close to 1/8th of an
inch below the peel blade edge.
Goal:
Adjust the tamp pad closer to or further away from the baseplate to align the label to the pad.
This position should allow a column of vacuum holes to be covered, while triggering the label
present sensor.
•••• Sub-Step (a) ••••
Loosen the two dovetail track screws [A] (1/4 inch socket-
head cap screws) and slide the tamp cylinder assembly
into a position that gives approximately 1/8 inch gap
between the peel blade edge and the tamp pad. Once in
position, tighten the dovetail track screws firmly.
•••• Sub-Step (b) ••••
Loosen the tamp cylinder mounting screws [B] (1/4 inch
socket-head cap screws) and slide the tamp cylinder in
and out from the baseplate to align the label with the pad.
It is important that the label dispensed covers the ported
vacuum holes and covers the label present sensor (if
equipped). These screws adjust the tamp pad height, in
relation to the peel blade edge. Before locking the screws
in place from adjusting the in-and-out position, set the
height. The labels are optimally transferred to the tamp
pad when the pad is 1/8th inch below the peel blade edge.
This keeps any label curl at the end of the label from
landing back on the peel blade edge. As the label’s
adhesive is exposed to air, the tendency is to shrink, or
curl away from the tamp pad. Some curl at the end is
expected, and by keeping the pad below the peel blade
edge, labels curling back to the liner will be avoided.
Once the pad has been adjusted, tighten the screws and
apply air pressure to the system and re-check the tamp
pad position. The adjustment of the tamp cylinder’s air
cushion will effect the resting height at home of the
cylinder, and thus the tamp pad. Be sure to check this
height again, after all pressures and adjustments to the
tamp system are complete. If the position looks correct,
tighten the mounting screws firmly.
