When the relay is in IRF error (the Home button flashes red fast), the
backup is not made.
The relay's device certificate and the CA root certificate are not part of
the backup. If PKI has been configured, this must be reconfigured using
the corresponding tools. In addition, when PKI is in use, CAM settings are
not restored to avoid the condition where the relay is not able to contact
the configured CAM server.
6.3.2 Rebooting the software
1. Select Configuration> General> Software reset.
2.
Tap Edit, select Activate and tap
.
6.3.3 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.
• Select Configuration> General> Factory setting to restore factory settings.
•
Tap Edit, select Activate and tap .
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.
