Systems of safety light curtains that operate in close proximity to each other can inter‐
fere with each other.
b
Use appropriate measures to prevent systems in close proximity from interfering
with each other.

Using reversed direction of transmission
T
he direction of transmission of the system " can be changed during mounting by
switching the positions of the sender and receiver. With reversed direction of mounting,
the receiver " is not affected by the infrared light from the sender !.

4.4 Integration in electrical control
Overview
T
his chapter contains important information about integration in the electrical control.
Information about the individual steps for electrical installation of the device: see "Elec‐
trical installation", page 43.
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, the signal is analyzed by safety relays or a safety controller, for
example.

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 safety light curtain can fulfill its protective function.
•
It mus
t be possible to electrically influence the control of the machine.
•
The electrical control of the machine must meet the requirements of IEC 60204-1.
•
A restart interlock must be implemented depending on applicable national regula‐
tions or required reliability of the safety function. Because the safety light curtain
