Factory settings restoration

In case of configuration data loss or any other file system error that prevents the

protection relay from working properly, the whole file system can be restored to the

original factory state. All default settings and configuration files stored in the factory

are restored. For further information on restoring factory settings, see the operation

Function block

The protection relay is provided with a load profile recorder. The load profile feature

stores the historical load data captured at a periodical time interval (demand interval).

Up to 12 load quantities can be selected for recording and storing in a nonvolatile

memory. The value range for the recorded load quantities is about eight times the

nominal value, and values larger than that saturate. The recording time depends on a

settable demand interval parameter and the amount of quantities selected. The record

output is in the COMTRADE format.

Selectable quantities are product-dependent.
