In the antivalent circuit, switches can be
connected in different ways. The decisive
factor for enabling is where the normally
closed contact is connected.
n
Example 1: The LEDs of the inputs are off
when not actuated and light up when
actuated. Use: e.g. for door monitoring with
magnetic reed contacts

Example 2: The LEDs of the inputs are off
when actuated and light up when not
actuated. Use: e.g. for two-hand switches
with two separate contacts

With this connection and corresponding para-
meterization, the pulsing of pins 1 and 5 is
switched off. The supply voltage at pin 5 re-
mains switched on.
To avoid errors, do not use 5-pole cables
to the sensor.

With this connection and corresponding para-
meterization, the pulsing of pins 1 and 5 is
switched off. The supply voltage at pin 5 re-
mains switched on. The NC contact is connec-
ted to pin 2 in order to receive a release when
it is actuated. Connection example: Banner STB

To avoid errors, do not use 5-pole cables
to the sensor.
