Using ProLogic
to Qualify
Group Logic
Statements
Select from any available ProLogic inputs to make specific blocking logic to
be used as a qualifier for any group logic decisions. In this example we use ei-
ther the zone 1 or zone 2 phase distance elements or the communications trip
or the communications send or the Power Swing outer blinder alarm to drive
the Block Group Logic statement. There is no intentional pickup delay and 0.5
second drop-out delay to hold the block on after the block condition has reset.
