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.

Using reversed direction of transmission
Using reversed direction of transmission
The direction of transmission of the system
2
can be changed during mounting by
switching the positions of the sender and receiver. With reversed direction of mounting,
the receiver

Important information
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
b
Make sure that the following control and electrical requirements are met so that
the product can fulfill its protective function.
Requirements for use
The output signals of the protective device must be analyzed by downstream controllers
in such a way that the dangerous state of the machine is ended safely. Depending
on the safety concept, signal evaluation is carried out e.g. with safety relays or with a
safety controller.
