7.3.2 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 stored in the factory are restored. As
the device has no configuration, the warning Config. not available is
displayed.
Only the administrator can restore the factory settings.
1.
Select Main menu/Configuration/General/Factory setting and press
.
2.
Set the value with
or and press .
3.
Confirm by selecting Yes with or and press .
The protection relay restores the factory settings and restarts. Restoring takes 1...3
minutes. Confirmation of restoring the factory settings is shown on the display a
few seconds, after which the relay restarts.
Avoid the unnecessary restoring of factory settings, because all the
parameter settings that are written earlier 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.
