Reset LEDs
If the element tripped have gone back to rest condition, the latched LEDs and/or relays may be
reset.
Set profile
Inside Pro-N devices, two independent setting profiles (A and B) are available. Whereas different
settings are required, they are made in the setting profiles and stored in the non volatile memory of
relay. Applicable setting profile is activated usually via a binary input; when the programmed input is
activated, the profile B becomes operative as a replacement for the default profile A.

Fault trigger
When the programmed input is activated, a trigger is issued for fault record SFR). Data storing takes
place with the same procedure resulting from a trip of any protective elements
Note 1 To enable the profile switching the “Input-selected” parameter must be set inside the “Profile selection” submenu.
If multiple setting groups are not required, Group A is the default selection
