3.6 Interference / Beam coding
If there is a risk of a receiver picking up the light signals from other
transmitters, each system must be operated with its own beam coding

No interference
Reciprocal interference!
Beam coding is required
Four different beam codings can be set (see section on setting the
parameters) The beam coding must be set in pairs (transmitter and
receiver)

Reciprocal interference from systems is to be avoided by
choosing suitable mounting positions or by configuring
different beam codings
The user is at risk if systems are operated with reciprocal
interference
The response time of the system changes with the selected
beam coding The safety distance must be adapted
accordingly See section on reaction time
When the system starts, the integrated signal lamp indicates
the set beam coding by the corresponding number of light
impulses
If an AOPD is operated with no other neighbouring systems,
beam coding 5 with a very short reaction time (7 milliseconds)
can be selected
