The value "no position detection" means that no final position feedback is connected to the valve coupler.
The current reference value is returned as valve position to the function block.

If "Use sensor values for PV_D" is selected, the two signals of the PFCs are transferred to the function block
without evaluation. The two binary signals are represented on bit 0 (PFC A) and bit 1 (PFC B). Here numer-
ical values can be generated from 0 ... 3. The problems which may result here are described in section
"PV_D generation".

When selecting one of the options A to D, the transducer block determines from the PFC signals in which
position ("open", "closed", "intermediate") the valve is just at that moment. Whether an actuated sensor or
activated mechanical contact represents an open or closed valve, depends on the construction of the posi-
tion feedback and the electrical characteristics of the PFCs. A general representation is thus not possible.
Each of the four options corresponds to one set of combinations of the two PFC signals and the valve po-
sitions "open", "intermediate" and "closed". The following four tables show which valve position which com-
bination of the signals of PFC A and PFC B are assigned for the options A to D.

The letter/number combinations after the options A to D give the signal input for the positions "open" (O),
"intermediate" (I) and "closed" (C). The assignment of the PFC signals "0" and "1" to the numerical values
0 ... 3 is given in the following table.

The valve coupler interprets a PFC signal as follows:
high current

=> logical 1

low current

=> logical 0
