AUTOMATIC LEARNING MODE: IΔ

AUTO CONFIGURATION MODE
Principle
Auto coniguration feature on the
DIRIS A80
allows
the user to build the IΔn and I
PE
threshold curve direct
-
ly based on his electrical installation. The
DIRIS A80
integrates a method of threshold auto learning allowing
the user to conigure easily the threshold curve.
In auto coniguration mode, the points for IΔn and I
PE
are illed with the values directly measured by the dif
-
ferential current transformers.
During the automatic learning process, the user has
to be able to change the load level of its installation
on a wide range in order to create the curve of the
nominal differential current according to the load cur-
rent representative of the installation.
The user adds an offset value on the IΔn and I
PE
mea-
sured points to deine the threshold level.
This offset value represents the delta between the
normal IΔn (or I
PE
) current level of the installation and
the level generating an alarm. By default the offset
value is set to 0.
