relay
On application of the supply
voltage the output relay pulls in
and the timing period ts starts.
Current control with no latch
(auto reset) function
At the end of ts,
when the
measured current exceeds the
set threshold, timing period tr
starts. At the end of tr the output
relay changes over if the current
measurement still exceeds the
threshold.
The output relay resets immediately
when the monitored
current reaches the hysteresis
set value.
.
Current control with latch
(manual reset) function.
At the end of ts,
if the measured
current exceeds the set threshold,
timing period tr starts. At the end
of tr the output relay changes over
and remains in this condition, even
if the monitored current reaches
the hysteresis set value.
An external reset (S1) must be
operated to reset the relay.
