– mode
If the monitored value is
less than the lower-
limit and, time T1 has
expired.
I
Up
– mode
If the monitored value is
higher than the
upper limit, and
time T1 has expired.
I
Lo
I
Up
– mode
If the monitored value
of voltage is outside
of the upper or lower
limits, and time T1 has
expired.
Inrush current < T2
is ignored
Current dips < T1 do
not result in output
relay switching off.
