2.12. Programmable stages (99)
For special applications the user can built his own protection
stages by selecting the supervised signal and the comparison
mode.
The following parameters are available:

Priority
If operation times less than 60 milliseconds are needed
select 10 ms. For operation times under one second 20 ms
is recommended. For longer operation times and THD
signals 100 ms is recommended.

Link
The name of the supervised signal (see table below).

Cmp
Compare mode. „>‟ for over or „<‟ for under comparison.

Pick-up
Limit of the stage. The available setting range and the
unit depend on the selected signal.

t
Definite time operation delay

Hyster
Dead band (hysteresis)

NoCmp
Only used with compare mode under („<‟). This is the limit
to start the comparison. Signal values under NoCmp are
not regarded as fault.
