5.6 GROUPED ELEMENTS

5.6GROUPED ELEMENTS
Each protection element can be assigned up to six different sets of settings according to setting group 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 config-
uration, season of the year, etc.). The active setting group can be preset or selected via the
Control Elements section later in this chapter). See also the Introduction to Elements section at the beginning of this chap-
ter.

Each of the six setting group menus is identical. Setting group 1 (the default active group) automatically becomes active if
no other group is active (see the Control elements section for additional details).
If the device incorrectly switches to group 1 after power cycling, upgrade the firmware to version 7.25, 7.31, or later to cor-
rect this issue.
