Replacing the Solenoid Valve for the Adjustment Unit [00369014-xx] (applicable to
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.

Replacing the Proximity Switch for the Adjustment Unit [00363268-xx] (applicable to
modular PCB conveyor only)
Parts
▪ Proximity switch for adjustment unit 1 [00363268-xx]
▪ Proximity switch for adjustment unit 2 [00363292-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.
► Loosen the grub screw at the cylinder switch (1) and
push the cylinder switch out of the adjustment unit
guide rail (2).
► Unthread the connection cable as far as the conver-
sion board of the assembly tub.
► Run the connection cable of the new cylinder switch
(2).
► Insert the new cylinder switch into the guide rail.
► Switch the machine on.
NOTICE! The width adjustment system cylinder
switch is set in engaged mode.
► Move the width adjustment system until the cylinder
switch switches - LED (H36/H37).
► Engage the cylinder - i.e. the cylinders are moved to
the upper limit by the controls.
► Set the cylinder switch so that the LED lights up when
it is in engaged mode.
► Fix the position of the cylinder switch (2) with the grub
screw.

The proximity switch serves as a signal for controlling the
pneumatic valve of the adjustment unit. Once the switch-
ing point has been reached, the conveyor edge is con-
nected via the short-stroke cylinder.
