Important information
DANGER
Hazard due to lack of effectiveness of the protective device
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.
b
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 or same cascade.
b
During alignment in particular, make sure that the laser beam does not hit any
external receiver.
DANGER
Hazard due to lack of effectiveness of the protective device
Systems of safety light curtains in close proximity to each other can mutually interfere
with each other.
b
Use appropriate measures to prevent systems in close proximity from interfering
with each other.
Preventing interference between systems in close proximity to each other
The following measures prevent interference from systems in close proximity:
•
Different beam coding for neighboring systems
•
Reversed direction of transmission for neighboring systems
•
Sender with a small scanning range
•
Optically opaque partitions

Using beam coding
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
Different beam codings only prevent mutual interference if both safety light curtains are
of type deTec4.
b
In the case of systems in close proximity that are of a different type, take different
measures to prevent mutual interference.
