When source
I
reappears, 1RT is started. At the end
of 1RT, source
I
is considered present. If source
I
disappears before the end of 1RT, the switchover is not
executed. If the replacement source disappears during
1RT, the latter dynamically and temporarily adopts the 3 s
setting value.

voltage is above the hysteresis value. This time delay must
be completed to enable transfer to Source
