Replacing the Light Barriers for Transmitter and Receiver Modules [00370063]
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.

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.
