1. 2.
In the antivalent circuit, switches can be con-
nected in different ways. The decisive factor
for enabling is where the normally closed con-
tact is connected.
n Example 1: The LEDs of the inputs are off
when not actuated and light up when actu-
ated. Use: e.g. for door monitoring with
magnetic reed contacts
n Example 2: The LEDs of the inputs are off
when actuated and light up when not actu-
ated. Use: as programming 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.
Note:
„ To avoid errors, do not use 5-pin 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
