Integral part of the controller
(0 = not effective)
Reset time:
Differential part of the

(0 = not effective)
In the case of an error, the
current output supplies the
current value defined in the
Current with error field (any in
the range
0 ... 21 mA).
In the case of an error, the
current on the output remains
unchanged.
Explanation
Using Save and quit, the nominal
amperage that was input as Inom
