PROGRAMMING
Principle of deining the threshold curves
CONFIGURATION MODE:
There are 2 ways of deining these curves :
MANUAL MODE:
Up to 6 points can be conigured to deine a curve.
The user has to give for each point 2 values:
• Pt LD => Value of the current load
• Pt TH => Value of the threshold of the differential
current
AUTOMATIC LEARNING MODE:
The automatic learning mode measures the nominal
differential current according to the load current of the
installation.
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.
Select “NO” to configure in MANUAL mode: see
chapter “MANUAL MODE”, page 33.
Select “YES” to conigure in AUTOMATIC mode: see
chapter “AUTOMATIC LEARNING MODE”, page 29.
