FUNCTION CHARACTERISTICS

Reset LEDs
If the element tripped have gone back to rest condition, the latched LEDs and/or relays may be reset.
Set profile
Inside XMR devices, four independent setting profiles (A, B, C, D) [two (A, B) for XMR-D only] 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 or C or D and viceversa.

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
