Removal
► Use the software or manually move the conveyor rail into a position which allows you best
access.
To move the conveyor side wall manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation.
Fig.127: Removing transmitter and receiver
The transmitters are always near the laser
warning labels(1). The receivers are always on
the opposite rails.
► (A) Transmitter:
Remove the five fastening screws(2)
and(3). Make sure that no parts fall into
the conveyor rail.
► (B) Receiver:
Remove the two fastening screws(4).
Make sure that no parts fall into the con-
veyor rail.
► Unplug the electrical connection.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
CAUTION
Installation instructions
► Reconnect the transmitter/receiver before installation.
► Make sure that all the other cables in the conveyor rail are run under the transmitter/receiver.
There is a particular lack of space at the transmitters.
► Use the bushing for the bottom screw. This screw is used to fix the sensor.
The two upper screws are used to adjust the laser beam.
► The transmitters are fixed hand-tight with the lower screw and adjusted with the top two screws.
► Check the setting for the transmitter / receiver and correct it if necessary (see 3.5.1.6.4.1 "Setting
the fiber optic sensor" [}101]).
► Teach the PCB sensors using the station software (see Teaching the PCB sensors (SW70x)).

Correcting the laser light barrier setting
DANGER
Laser Class 2
The laser light barrier transmitter emits class 2 laser beams. You therefore do not require additional
protective measures!
► However, you should never look into the laser beam.
► Adjust the laser beam only from the rear side of the laser!
