Removal
► Use the software or manually move the conveyor rail into a position which allows you best ac-
cess.
– To move the conveyor rail 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. Observe the instructions in section 1.2 "Preparatory Work..." [}15].
► Move all gantries out of the transport area as far as possible at one side of the machine.
Fig.223: Removing transmitter and receiver
The transmitters are always near the laser warning la-
bels(1). The receivers are always on the opposite
sides.
► (A) Transmitter:
Remove the five fastening screws(2) and(3).
Make sure that no parts fall into the conveyor rail.
► (B) Receiver:

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 if necessary (see 7.6.5.1
"Setting the Fiber Optic Cable Sensor" [}176]).
► Teach the PCB sensors using the station software (see 7.10 "Teaching the PCB
Sensors (SW70x)" [}192]).
