16.5 Position feedback signal
The valve position feedback indicates the valve travel. It uses an analog signal issued at the
terminal U OUT or I OUT. The span of the position feedback signal is adjusted over the lower
and upper range value parameters.
− At least 2.5V or 5mA (depending on the input signal used) must separate the upper and
lower range values.
− When c37 = YES, the position feedback signal is 12V or 24mA in the event of a fault.
− During initialization, transit time measurement or zero calibration, the position feedback
signal = 0V or 0mA.

16.6 Binary input
Thefunctionofthebinaryinputcanbeconguredasrequired.Codec12isusedtodeter-
mine the switching state for the active function. c12 = NINV: the binary input is active when
the input terminals IN4+/IN4– are connected with each other. c12 = INV: The binary in-
put is active when the connection between the input terminals IN4+/IN4– is interrupted.
Î Do not connect an external supply voltage to the input terminals.
− Inactive (c11 = NONE): No function is assigned to the binary input.
− Priority position (c11 = PRIO): The priority position is triggered and the actuator stem
moves to the position entered in Code c34 as soon as the binary input changes to the ac-
tive switching state. The valve leaves the priority position and follows the input signal af-
ter the binary input changes to the inactive switching state.
− Next entry in information level (c11 = NEXT): If the NEXT function is selected in
Codec11,therstcodeoftheinformationlevel(i01)isdisplayedassoonasbinaryin-
