Fig. 20 Sensors on cylinder Z
Sensor Start Position 1
1. Loosen screw (1) on sensor (3) "Start Position" and move the sensor so that the top edge of the sensor is on the
samelevelasthesensorholderandtscomfortablyintoit.
2. Close the compressed air supply and pull out the tubes from cylinder-Z. Switch on the printer with an existing
connection to the applicator via the electronic interface (SUB-D).
3. Manually move the pad to the top of the stopper.
4. Loosen screw (2) on the sensor holder.
5. Move the sensor so that the LED lights up when the cylinder is completely contracted. A distance of 10 mm
between the top edge of the sensor and the lower edge of the connecting ring of cylinder is required as illustrated
inthegureabove.
6. Tighten screw (2).
Labelling Sensor 2
The position of the labelling sensor (6) is dependant on the pad assembly's weight and the angle of the mounting
position. The triggering magnet is integrated into the adapter bolt.
1. Bring the printer and applicator into their intended operational position.
2. Swing the pad in the labelling position.
3. Loosen screw (5) and move the sensor (4) so that it triggers and the LED lights up when the adapter bold is
driven into the tamp assembly group.
4. Tighten screw (5).

Fig. 21 Throttle valves on the cylinder Z
The speed of the pad movement can be regulated via two throttle valves (1 and 3).
Adjust the pad movement speed as necessary.
To increase the downward speed turn the screw (4) at the lower valve (3) counterclockwise.
To increase the upward speed turn the screw (2) at the upper valve (1) counterclockwise.
!
Attention!
The time for the downward movement of the pad may not exceed 2 seconds
Otherwise the error message "Lower position" will appear.
i
Note!
To reduce the air pressure in Z-direction an optional pressure reduction valve (5) is available.

The pressure reduction valve (2) will when labelling pressure-
sensitive products or to increase generally safety by reducing
the pressure of the cylinder in Z-direction.
The standard value is 2.5 bar.
Connect the manometer between tube and exit (3) and
adjust the pressure to 2.5 bar via knurled screw (1).
It is possible to upgrade to the pressure reduction as a set
order with instructions, or as an integrated part of the default
factory order.

hindering the label on its way from the printer to the pad this is also dependant on the label material being used.
The label should cover all the suction holes of the pad.
The standard factory value of the vacuum of the pad is -0.6 bar.
i
Note!
By adjusting the vacuum of the pad the transportation of the label from the dispensing edge to the pad will
be affected.
If the vacuum is too strong the label will not reach the intended position on the pad.

Fig. 23 Throttle valve "vacuum"
Adjust the vacuum with the throttle valve "vacuum" (1) so that the label is sucked onto the pad over the entire
area of the label.
To increase the vacuum turn the setting screw of the throttle valve (1) counterclockwise.

Fig. 24 Measure the vacuum
Use a manometer with a measuring range of -7 to 7 bar.
MP V: Vacuum (default value -0.6 bar)
1. Remove the cover.
2. Cover the suction plate hermetically.
3. Attach the manometer to the MP V.

4. Activate the valve manually by pressing the micro switch
(3) while the compressed air is switched on.
5. Adjust the vacuum via the throttle valve "vacuum" as
required.
6. Remount the cover.

Attention!
After pressure measurements, connect all component exactly and check it.
