GROUPED ELEMENTS
5.7 Grouped elements
5.7.1 Overview
Each protection element can be assigned up to six sets of settings with designations 1 to 6. The performance of these
elements is defined by the active setting group at a given time. Multiple setting groups allow the user to conveniently
change protection settings for different operating situations (for example, altered power system configuration or season of
the year). The active setting group can be preset or selected in the
later in this chapter). See also the Introduction to Elements section at the beginning of this chapter.

Each of the six setting group menus is identical. Setting group 1 (the default active group) is active automatically when no
other group is active.
If the device incorrectly switches to group 1 after power cycling, upgrade the firmware to version 7.31 or later to correct
this issue.
