Restoring factory settings
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. Only the ADMINISTRATOR can restore the factory settings.

The protection relay restores the factory settings and restarts.
Avoid unnecessary restoring of factory settings, because all the
parameter settings written to the relay will be overwritten with the
default values. During normal use, a sudden change of the settings can
cause a protection function to trip.
