Tab. 3: Function of the DIP switches
Information about the communications software:
The switching position of the DIP switch has priority over
the communications software!
If the values of the sealing function (CUTOFF) or the cor-
rection characteristic (CHARACT) are changed via the
software tool, the corresponding function must be active
(DIP switch set to ON).
The effective direction of the set-point value (DIR.CMD) can
be changed via the DIP switches.
