DIP Switches Position Function
1 ON Reversal of the effective direction of the set-point value ( DIR.CMD)
(set-point value 20 – 4 mA corresponds to position 0 – 100 %),
descending
OFF Normal effective direction of the set-point value
(set-point value 4 – 20 mA corresponds to position 0 – 100 %),
ascending
2 ON Sealing function active. The valve completely closes below 2 % 10) and
opens above 98 % of the set-point value ( CUTOFF)
OFF No sealing function
3 ON Correction characteristic for adjustment of the operating characteristic
(linearization of the process characteristic
CHARACT) 11)
OFF Linear characteristic
4 ON Operating status MANUAL (BY HAND)
OFF Operating status AUTOMATIC (AUTO)

Information about the communications software:
The switching position of the DIP switch has priority over the settings via the communications software!
If the values of the sealing function ( CUTOFF) or the correction characteristic (CHARACT) are changed
via the communications software, the corresponding function must be active (DIP switches set to ON).
The effective direction of the set-point value (
DIR.CMD) can be changed via the DIP switches only.
If the correction characteristic ( CHARACT) is not changed via the communications software, a linear char-
acteristic is saved when DIP switch 3 is set to ON.
A detailed description of the functions can be found in the chapter entitled “Basic functions” and in the
operating instructions for the communications software.
