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.
Factory setting, can be changed via communications software.
