4.1.4 Mutual optical interference of systems mounted in close
proximity
Prevent mutual optical interference between systems mounted in
close proximity!
If several L 4000 systems work in close proximity, then the sender
beams from one system can cause interference in the receiver for
the other system such that the protective function of the various
L 4000 systems is no longer provided and there is a hazard for the
operator. You must avoid this type of mounting situation or take suit-
able precautions, e.g., by mounting non-reflective screens or by re-
versing the transmission direction of one of the systems.
