4.4.12 Replacing the Limit Switch for the End Position Width Adjustment System [00365108-xx]
Replacing the Limit Switch for the End Position Width Adjustment System [00365108-
xx]
Parts
▪ Limit switch on the assembly tray [00365002-xx]
▪ Limit switch for width adjustment 1 [00365108-xx]
▪ Limit switch for width adjustment 2 [00365109-xx]
▪ Limit switch for width adjustment - on the conveyor side [00362345-xx]
Overview

Limit switch on the input conveyor:
In the vicinity of the input conveyor there are 4 limit
switches under the conveyor sides. The limit switch is de-
signed to prevent the conveyor sides hitting one another
or the conveyor base.
Limit switch on the output conveyor:
There are 2 limit switches for the adjustment unit in the vi-
cinity of the output conveyors. They serve to secure the
transport area and to initialize the adjustment unit during
width adjustment.

modular PCB conveyor only)
Parts
▪ Solenoid valve with cable for adjustment unit 1 [00363779-xx]
▪ Solenoid valve with cable for adjustment unit 2 [00363780-xx]
Overview
NOTICE! The limit switches are preassembled
and include cables.
However, if the limit switch itself is faulty, the wiring can
be unsoldered/soldered right at the switch in question.
► Unsolder the connection wires on the faulty limit
switch (1).
► Loosen and remove the two screws (2) fastening the
defective limit switch.
► Fit the new limit switch and re-solder the connection
wires in the correct allocation.
NOTICE! If you have discovered a break in the
connection cable during a continuity check, this cable
must be unthreaded as far as the conversion board of the
assembly tray and unplugged there.
This might be somewhat complicated depending on the
routing of cables inside the machine base.
You may wish to contact Siemens AG SMD Service re-
garding this work.
Checking the position of the limit switch:
► Check the minimum and maximum width of the rele-
vant machine type and the parallelism of the convey-
or sides.

► Move the PCB conveyor to the position which gives
you best access to the adjustment system.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Switch off the compressed air supply.

Replacing the Cylinder Switch for the Adjustment Unit [00369016-xx] (applicable to
modular PCB conveyor only)
Parts
▪ Cylinder switch of width adjustment 1 [00363267-xx]
▪ Cylinder switch of width adjustment 2 [00363291-xx]
Overview
► Move the PCB conveyor to the position which gives you best access to the adjustment system.
► Move the Y gantries into the area outside the PCB conveyor.
► Switch off the machine and secure it to prevent unauthorized reactivation.
► Switch off the compressed air supply.
► Remove the compressed air connections (2).
► Loosen the two fastening screws and remove the so-
lenoid valve (3) from the short-stroke cylinder.
► Unthread the connection cable (1) as far as the rele-
vant assembly tub conversion board and unplug.
NOTICE! This might be somewhat complicated
depending on the routing of cables inside the machine
base.
You may wish to contact Siemens AG SMD Service re-
garding this work.
► Fit the new solenoid valve (3) and reconnect the sys-
tem to the electrical (1) and compressed air (2) sup-
plies.

The cylinder switch on the adjustment unit cylinder
should operate when the adjustment unit pin is pushed
out by the pneumatic cylinder and therefore connected to
the conveyor side. This signal enables the width adjust-
ment motor.
