Heading. For protections S, I and G it is possible to select disablement of the function. For protections S and G
it is also possible to select the type of curve.
Select which threshold value I1 to set. At the side of selection of threshold I1, its value expressed in Amperes
will also be displayed automatically.
Select which trip curve t1 to set.
Select whether to enable or disable operation of protection L with thermal memory.

Select which trip curve to set (this is not possible for I).
For protection S it is possible to decide whether to enable or disable the thermal memory.
For protections S and G it is possible to decide whether to enable or disable the zone selectivity.
For protection G it is possible to decide whether to enable or disable the trip control at the end of timing.

13.15.2.2 Modification of protection functions
The basic configuration of the unit must be made in EDIT mode.
This paragraph allows the user to program the protection functions implemented with the PR112 unit. Only the data programming methods and
which values can be set are given. For all the other information relative to the technical characteristics of these protection functions, please refer
to the “Protection functions” par..
Following the instructions given under chapter. 13.12, show the following on the display to set protection functions L, S, I and G:
Depending on the method used on the first line, the following pages will be displayed if PR020/K=ON:
