Therefore, the delay between pow loss and the opening longer
than (e.Strategy delay set too long com pared the other delays, once the gen
set started and the delay has elapsed, the 010 till aits the net anomaly
detection delay, T1, elapse before opening irc breaker -N..

Ind icatio the signals the diagrams:
V ok: norm line voltage present and ith set lim its
(1 ok, ko)
C on: norm line breaker closed closed, open)
G start: gen set started start, stop)
V-E ok: emergency line voltage present and ith set lim its
(1 ok, ko)
C B-E on: emergency line breaker closed closed, open)
L off: ity tiv s
