The non-volatile latches provide a permanent logical flag that is stored safely and do not reset upon restart after the relay
is powered down. Typical applications include sustaining operator commands or permanently blocking relay functions,
such as Autorecloser, until a deliberate interface action resets the latch.
LATCH 1 TYPE
— This setting characterizes Latch 1 to be Set- or Reset-dominant.
LATCH 1 SET

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
SETTING GROUPS
menu (see the Control Elements section
later in this chapter). See also the Introduction to Elements section at the beginning of this chapter.
