Refitting the wafflepack changer
NOTE
Every other time the cutter unit is maintained you should also maintain the wafflepack changer.
Re-install the wafflepack changer (see the Component supply section of this user’s manual)
Pay attention to the rotational position of the magazines and the correct assignments of the magazines to
the tray (see Section 9.8, Wafflepack Changer). The position of the wafflepack changer is automatically
recorded following loading of a placement program which includes components being picked up from the
wafflepack changer.
9.3.5 Compressed Air Unit
NOTE
The intervals at which this maintenance work is carried out will depend directly on the quality of the com-
pressed air used. If you fail to meet the quality requirements of the compressed air specification, you should
carry out maintenance more frequently. To prevent contamination in the vacuum circuits of the placement
heads (which is very complicated to remove) you should make sure you change the filter cartridges before
error messages occur.
9.3.5.1 Checking the 5.1 bar Operating Pressure
NOTE
Excessive or inadequate operating pressure will primarily result in vacuum faults, leading to a fatal error mes-
sage and interruption of placement.
For the following work the main switch of the machine is switched on.

Hose connector with hose clamp
Check the pressure displayed on lefthand manometer (see Fig. 9.3.5): during operation the manometer
should display a pressure of 5.1 bar.
If this is not the case, this may be due to the following reasons:
– The pressure in the supply network is too low. It must be 6 bar
– The filter in the compressed air unit is contaminated
– There is a leak in the compressed air supply or
– The drain plug has not been tightened up or is leaky.
NOTE
For the compressed air supply use a ½" hose without reducer. The operating pressure of 5.6 bar is preset in
the compressed air unit and cannot be changed.
If it is not possible to achieve the operating pressure of 5.0 bar despite none of the above-mentioned reasons
applying, this means the compressed air unit is defective. You should inform Siemens’ SMD service depart-
ment.
9.3.5.2 2.3 bar Pressure for Stopper
Check the pressure displayed on the right-hand, upper manometer (see Fig. 9.3.5, page 9 - 29): a pres-
sure of 2.3 bar must be displayed.
If this is not the case, remove the cover plate (see Fig. 9.1.1, page 9 - 3) from the machine base (hexagon
socket spanner, size 3) and correct the setting at the adjustment knob up and to the right.
9.3.5.3 Draining the Condensate
PLEASE NOTE
Make sure that there are no components on the placement heads before you carry out this work.
WARNING
NEVER drain off the condensate under pressure.
Remove the cover plate from the compressed air unit.
Close the shut-off valve the compressed air unit (see point 12 in Fig. 9.3.5, pages 9 - 29).
Wait a few moments until the lines have depressurized. The two manometers (see points 4 and 11 in Fig.
9.3.5, pages 9 - 29) must read 0.
