beam coding
Notes · Beam coding increases the availability of the protected machine. Beam coding also en-
hances the resistance to optical interference such as welding sparks and similar.
· In a cascaded system, host and guest can be operated only with the same beam coding.
· Beam coding will increase the response time of the system. This may also change the re-
quired safety distance. For details refer to chapter 4.1 “Determining the safety distance”
on page 22.
· After activating the system, sender and receiver will briefly display the coding.
· If operated with beam coding, the number of beams in cascaded systems must not ex-
ceed 405 beams.

3.4.4 Scanning range
WARNING
a
Match the scanning range with the protective field width!
The scanning range of the system (host, guest 1 and guest 2) must be adapted to the width
of the protective field.
· If the scanning range is too small, the light curtain will not change to green.
· If the scanning range is too great, the light curtain may malfunction. This would mean that
the user/operator is at risk.
Note If you are using the additional front screen (see page 56) available as an accessory, the
useful scanning range will be reduced by 8% for each additional front screen.
The available settings depend on the physical resolution of the system:
