Replacing the Proximity Switch for the Adjustment Unit [03040795-xx] (applicable to
modular PCB conveyor only)
Overview
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 edge is connected via the short-stroke cylinder.

3. Transport direction
► 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.
► 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 conveyor
edge:
► Position the adjustment unit, with the help of the width
adjustment belt, so that the proximity switch can be
easily accessed.
► Place a 4/10mm distance gauge on the adjustment
unit and press this distance gauge against the adjust-
ment unit.
► Push the proximity switch upwards, as far as the stop
and tighten the fastening screw.
NOTICE!
Perform a width adjustment function test at all conveyor
sides.
► Use the SITEST program to calibrate the conveyor
edges.

Replacing the Transmitter
► Dismantle the holder and the transmitter.
► Unscrew the transmitter from the holder.
► Unthread the connection cable as far as the relevant plug in the conveyor edge.
► Unplug the connector plug.
► Rerun the connection cable accordingly and reconnect the plug on the conveyor edge to the electri-
cal system.
► Fix the new light barrier in the original position.
Parts
Please note the different item numbers for the individual
light barriers - these are for the different lengths of the
connection cable.

NOTICE
Important instructions for replacing the light barrier
► When looking in the direction of transport, the transmitter is always on the left.
► Check whether it would be helpful to feed in the new cable with the aid of the old one, at
least in some areas.
