7.2 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.
7.3 Restoring the administrator password
If authentication is enabled in the protection relay and the administrator password
is lost, it is no longer possible to change passwords or operate the relay with full
access rights.
• Contact ABB technical customer support to retrieve back the administrator
level access to the protection relay.
•
Generate a one-time password by pressing and simultaneously.
The OTP can be generated only when the LHMI display prompts for the
ADMINISTRATOR password.
