4.4.15 Replacing the Proximity Switch for the Adjustment System [00363268]
Parts
Proximity switch for adjustment unit 1 [00363268]
Proximity switch for adjustment unit 2 [00363292]
Overview
X Move the PCB conveyor to the position which gives you best access to the adjustment system.
X Move the Y gantries into the area outside the PCB conveyor.
X Switch off the machine and secure it to prevent unauthorized reactivation.
X Switch off the compressed air supply.
Removal/Installation
The proximity switch serves as a signal for
controlling the pneumatic valve of the adjustment
unit. Once the switching point has been reached,
the conveyor side is connected via the short-
stroke cylinder.

X Loosen the grub screw on the clamping device
(1) and unthread the connection cable as far
as the conversion board of the assembly tray.
X Fit the new proximity switch and reconnect the
system to the electrical supply.
X Fix the proximity switch with the grub screw.
X The grub screw must be tightened with a
tightening torque of 20 Ncm (+ 3Ncm). The
proximity switch must to lie flat with the
housing (2) of the adjustment unit.
X The switching point is set at the actuator on the
conveyor side:
X Move the adjustment unit until it is under the
conveyor side.
X Place a 4/10 mm distance gauge on the
adjustment unit, press the actuator onto the
distance gauge and tighten the screw.
NOTE:
This setting must be performed at all
conveyor sides.
X Use the SITEST program to calibrate the
conveyor sides.

NOTE: 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.
