(Output Open)
Signal is output with the corresponding valve
position. Detection of Open depends on the setting of the
parameter
Position Feedback
(index 0x51 (see “Actuator po-
sition feedback“, page 45)) and a correct initialization.
1
(Output Close)
Signal is output with the corresponding valve
position. Detection of Close depends on the setting of the
parameter
Position Feedback
(index 0x51 (see “Actuator po-
sition feedback“, page 45)) and a correct initialization.

(Output Error)
Only output error detection.
3
(Output Error & Warning)
