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 “12.1. Basic functions” and in
the operating instructions for the communications software.
