4.3.4 Protection against interference from systems in close proximity to each other
Overview
Figure 12: Preventing mutual interference from system
1
and system
2
The infrared light beams of the sender of system1 can interfere with the receiver of
system2. This can disrupt the protective function of system2. This would mean that
the operator is at risk.
Important information

The integrated laser alignment aid may influence the receiver of a safety light curtain
in close proximity. In such cases, the neighboring safety light curtain may not detect
persons or parts of the body that require protection.
►
Perform an alignment or take other measures to ensure that the laser beam only
hits the front screen of the relevant receiver. The laser beam must not hit any
external receiver should the integrated laser alignment aid be switched on by
mistake or due to a fault. An external receiver is a receiver that is not part of the
same safety light curtain.
►
During alignment in particular, make sure that the laser beam does not hit any
external receiver.

Systems of safety light curtains in close proximity to each other can mutually interfere
with each other.
►
Use appropriate measures to prevent systems in close proximity from interfering
with each other.
Preventing interference between systems in close proximity to each other
T
he following measures prevent interference from systems in close proximity:
•
Different beam coding for neighboring systems
•
Reversed direction of transmission for neighboring systems
•
Optically opaque partitions
