6.13.4.2 Removal/installation
NOTE:
The limit switches are pre-assembled and include cables.
However, if the limit switch itself is faulty, the wiring can also be unsoldered/soldered right at the
switch in question.
Æ Unsolder the connection wires on the faulty limit switch (see also Section 6.16 and Section
6.17).
Æ Undo and remove the two screws on the faulty limit switch.
NOTE:
If you have discovered a break in the limit switch cable during a continuity check, the cable must
be woven out as far as the conversion board of the mounting tray (see circuit diagrams of the
same name) and unplugged at the corresponding point. (see also Section 6.16
and Section 6.17).
This may be somewhat complicated depending on the routing of cables inside the machine base.
You may wish to contact Siemens Dematic AG SMD Service regarding this work.
Æ Install the new limit switch and re-solder the connection wires with the correct allocation.
6.13.4.3 Checking the position of the limit switch
Æ Check the minimum and maximum width for the relevant machine type and the parallelism of
the conveyor sides.

Parts
– 00363779-02 Adjustment unit valve 1
– 00363780-02 Adjustment unit valve 2
Æ Move the PCB conveyor to the position which allows you best access to the adjustment unit.
Æ Move the Y-gantries into the area outside the PCB conveyor.
Æ Turn the machine off at the main switch and disconnect the machine from the mains voltage.
Æ Switch off the compressed air supply.
Æ Make sure the machine has been properly secured to prevent it being switched on again during
servicing.
Æ Undo and remove the screw fastening the connection plug (see also Fig. 6.13.27).
Æ Disconnect from the pneumatic system.
Æ Undo the two fastening screws and remove the valve from the short-stroke cylinder.
