– If you cannot get the required 5 bar pressure, replace the pressure regulating valve (after disconnect-

ing the machine from the power supply and compressed air network!) or inform the SMD Service

department of Siemens AG.

– If the compressed air was at the correct pressure, check the pressure at the block of the components

table pneumatic system (service manometer). If you measure a different value:

DANGER QQQ

Switch off the machine at the main switch and disconnect it from the main power supply.

● If necessary, check the compressed air hose which runs in the interior of the machine base. If the

compressed air hose is pinched, replace it. Fit the cable lacings back in place, reconnect the

compressed air hose to the block and to the components table compressed air supply.

● Connect the machine to the mains and switch on.

● Fit the cover to the machine base (size 3 screwdriver for socket-head screws).

● If you still have not been able to determine what the fault it, check the components table compressed air

supply unit.

7.7.3.1 Fault Location and Correction: Components Table Compressed Air Supply

● Check the clamping clip of (see Fig. 7.7.2, Item 1) of the module which is not conveying properly. It must

be correctly closed and press the module correctly against the support strip. If necessary, replace the

clamping clip (undo 2 countersunk screws M3).

● If this does not correct the fault, switch off the machine at the main switch and slide the corresponding

placement head by hand into the area within the PCB conveyor to prevent the head being damaged when

the modules are subsequently removed.

Note: You must observe a minimum clearance here of the x gantry axes - the axis must not be at the crash

switch (see User Manual, Section 9, subsection "Empty tape cutting device".
