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.

Using your finger, push the drain plug (see point 2 in Fig. 9.3.5, page 9 - 29) at the bottom end of the filter
hose (see point 3 in Fig. 9.3.5, page 9 - 29) up so that the condensate can drain into the tray.
Then open the shut-off valve for the compressed air supply (see point 12 in Fig. 9.3.5, page 9 - 29). The
drain plug will close automatically.
9.3.5.4 Replacing the Filter Cartridge, Cleaning the Filter Bowl
PLEASE NOTE
Make sure that there are no components on the placement heads when you carry out this work since the
automatic placement system must be switched off.
DANGER
• Switch off the automatic placement systems at the main switch and disconnect from the power supply.
• Switch off the compressed air supply at the shut-off valve in the compressed air unit.
Remove the cover plate from the compressed air unit (see Fig. 9.1.1, page 9 - 3).
In addition turn off the compressed air supply at the stop valve of the compressed air unit (see Fig. 9.3.5,
page 9 - 29).
Wait a few moments until the lines have depressurized.
WARNING
Never push the drain plug with a screwdriver in order to depressurize the lines.
Both manometers (see points 4 and 11 in Fig. 9.3.5, page 9 - 29) must read 0.
Remove the filter bowl by rotating it a quarter-turn and pulling it downwards (bayonet closure).
Clean the filter bowl if necessary. Never use acidic cleaning agents. Only use soapy water for this work.
Empty the condensate container.
Unscrew and remove the support spring and remove the sealing ring.
Pull the filter cartridge downwards and out.
Slide in the new filter cartridge.
Place the seal on the threaded rod and then screw on the support spring. The black plastic disk must be
placed in the filter bowl.
Screw the filter bowl back on.
Open the stop valve of the compressed air supply (see Fig. 9.3.5, page 9 - 29).
Switch the machine back on at the main switch.
Check the pressure at both manometers:
– operating pressure of the lefthand manometer: 5.6 bar
– operating pressure for the stopper at the right-hand manometer: stopper: 2.3 bar

NOTE
If, despite changing the filter cartridges, the manometers still do not show 5.0 bar and 2.3 bar this will be
due to other reasons, as described in Section 9.3.5.1 on page 9 - 28.
Reinsert the cover plate.
