In case of configuration data loss or any other file system error that prevents the protection device 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 a user with System Update right (refer to table Default roles-to-rights in the Cyber Security Deployment Guideline) (e.g. ADMINISTRATOR) can restore the factory settings.
The protection device 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 device restarts.
Avoid the unnecessary restoring of factory settings, because all the parameter settings that are written earlier to the device will be overwritten with the default values. During normal use, a sudden change of the settings can cause a protection function to trip.
