3.18 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 manual.

3.19.2 Functionality
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.
