1.1.1 Default settings restore
To restore the default values to the settings in any protection settings group, set the ‘restore
defaults’ cell to the relevant group number. Alternatively it is possible to set the ‘restore
defaults’ cell to ‘all settings’ to restore the default values to all of the relay’s settings, not just
the protection groups’ settings. The default settings will initially be placed in the scratchpad
and will only be used by the relay after they have been confirmed. Note that restoring
defaults to all settings includes the rear communication port settings, which may result in
communication via the rear port being disrupted if the new (default) settings do not match
those of the master station.
