6.6.2 Logic output (optional)

Analog output OUT3 can be used also as a logic output (O.typ = 0). This output can be used e.g. for pre-alarms.

6.6.3 Transmitter supply (optional)

With setting O.typ = 5, two-wire transmitter supply is possible via output OUT3.

In this case, the analog output of the unit is not available.
