6.5.2 Example: Connecting an inductive proximity switch (BEROs)
Boundary conditions
When connecting a BERO the following rules must be observed:
● BEROs can always be connected to each input.
● Because both the DI input terminals as well as the parameterizable DI/DO terminals are
isolated, the ground of the supply must be connected to the associated M terminal.
● When a connection is made to one of the parameterizable terminals, the positive pole of
the power supply must also be connected to the associated P connection terminal.
● Each group can be supplied with its own supply that is independent of the device supply.
In the simplest case can, however, everything can be fed from a single supply.
Nevertheless, all M and P terminals must be connected.
