configuration column, provided it is not the present active group. Similarly, a disabled setting
group cannot be set as the active group.
The column also allows all of the setting values in one group of protection settings to be
copied to another group.
To do this firstly set the 'Copy from' cell to the protection setting group to be copied, then set
the 'Copy to' cell to the protection group where the copy is to be placed. The copied settings
are initially placed in the temporary scratchpad, and will only be used by the relay following
confirmation.
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.

Front panel user interface (keypad and LCD)

When the keypad is exposed it provides full access to the menu options of the relay, with the
information displayed on the LCD.
The , ,  and  keys which are used for menu navigation and setting value changes
include an auto-repeat function that comes into operation if any of these keys are held
continually pressed. This can be used to speed up both setting value changes and menu
navigation; the longer the key is held depressed, the faster the rate of change or movement
becomes.
