4.3.4.3 Combining sufficient distance and reversed direction of transmission
Overview
T
o prevent mutual interference in the case of more than two neighboring systems, you
can combine the reversed direction of transmission and sufficient distance with each
other.
Example: Mounting 3 systems

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 39.
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.
