5.3 System with 2 light curtain and rotary encoder
NOTICE
Important for correct installation!
The light curtain for height measurement and the light curtain for width measurement must be
installed in one plane!
There must be no interfering contours between the transmitter and receiver, except in the
peripheral areas!
The encoder must be installed in such a way that no slippage can occur between the conveyor
belt and the friction wheel of the encoder!
The clamping device on the friction wheel must be set so that the friction wheel can be easily
moved with the conveyor belt!

The installation of the light curtains for width and height measurement is carried out analogously to
chapter 5.2.1.
Encoder installation
For a process-safe application, it is recommended to mount the friction wheel of the encoder from
below and slip-free opposite the conveyor belt.
The assembly instructions are enclosed with the encoder as a leaflet.
To replace the measuring wheel, consult the encoder mounting instructions.
For the electrical connection of the encoder, see chapter 6.4.
