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.

Parts
Please note the different item numbers for the individual light barriers - these are for the different lengths
of the connection cable.
Please consult the parts catalogue for the individual article numbers.
► Loosen the grub screw on the clamping device (1)
and unthread the connection cable as far as the con-
version board of the assembly tub.
► Fit the new proximity switch and reconnect the sys-
tem to the electrical system.
► Fix the proximity switch with the grub screw.
► Tighten the grub screw to a torque of 20 Ncm
(+3 Ncm). The proximity switch must be level with the
adjustment unit housing (2).
► The switching point is set at the actuator on the con-
veyor edge:
► Move the adjustment unit until it is under the convey-
or edge.
► Place a 4/10 mm distance gauge on the adjustment
unit, press the actuator onto the distance gauge and
tighten the screw.
NOTICE! This setting must be performed at all
conveyor edges.
► Use the SITEST program to calibrate the conveyor
edges.

NOTICE
Important instructions for replacing the light barrier
The transmitters are installed on the moveable side of conveyor models, while the receivers are
on the fixed side (applies to the standard conveyor system, fixed side - right).
Check whether it would be helpful to feed in the new cable with the aid of the old one, at least
in some areas.
The connection plug is equipped with contacts, which are pressed onto the wires. You may find
it helpful to remove the contacts from the connection plug, in order to run the cable better
through openings.
For replacement purposes, the connection cable must be unthreaded as far as the relevant
conversion board of the conveyor side. This might be somewhat complicated depending on the
routing of cables inside the machine base.
► You may wish to contact Siemens AG SMD Service regarding this work or proceed as fol-
lows.
