3.2 Wiring plan
Floating transistor output
(SWING E72 T)
Power supply: 10 … 55 V DC
(for further information see the following con-
nection examples as well as technical data)
To determine the switching status of the tran-
sistor output (mode A/B), the supply cable
(terminals 1 and 4) must be polarised re-
spectively.
Mode A
Max. detection or overfill protection:
- terminal 1: +
- terminal 4: –
Mode B
Min. detection or dry run protection:
- terminal 1: –
- terminal 4: +
Through different connections of the con-
sumer (load), NPN or PNP action can be
preset. Take care that during connection,
terminal 2 has always a more positive voltage
potential than terminal 3.
Connection examples
The transistor switches the supply voltage of
the oscillator to the binary input of a PLC or to
an electrical load.
