1.2 Configuration column (“Configuration” menu)
The relay is a multi-function device that supports numerous different protection, control and
communication features. To simplify the setting of the relay, there is a configuration settings
column which can be used to enable or disable many of the functions of the relay. The
settings associated with any function that is disabled are made invisible; i.e. they are not
shown in the menu. To disable a function change the relevant cell in the Configuration
column from Enabled to Disabled.
The configuration column controls which of the four protection settings groups are selected
as active through the ‘Active settings’ cell. A protection setting group can also be disabled in
the 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.
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 placed in the
temporary scratchpad and are only used following confirmation.
