Potentiometer fault: for end position CLOSED highest value is signali-sed,
for end position OPEN lowest value.
otherwise

Hardware fault: If this bit is set the PROFIBUS board must be checked.
otherwise

0
No reference operation: The values of the position transmitter cannot be used as long as the
reference operation (end position OPEN, end position CLOSED) has not been performed. A nominal
operation is not possible.

0
Remote operation via PROFIBUS in direction OPEN (remote operation bit for logic board set and
movement of potentiometer detected). Signalling of this bit requires a position transmitter.
otherwise

Remote operation via PROFIBUS in direction CLOSE (remote operation bit for logic board set and
movement of potentiometer detected). Signalling of this bit requires a position transmitter.
otherwise

Actuator runs locally in direction OPEN (local control or handwheel). Signalling of this bit requires a
position transmitter.
otherwise
