Type 71.41.8.230.1021 Switch off
ULo – mode
If the monitored value is
Programmable
less than the lowerlimit
and, time T has
expired.
MEMORY ON MEMORY OFF
U Lo...U Lo + Hys U Up...U Up – Hys U Up...U Lo
*RESET MEMORY = Pressing “SET/RESET“ > 1 s
Phase asymmetry
Incorrect phase rotation
Phase loss
LED ASY yellow
Phase asymmetry
LED DEF red
Voltage to A1 (1) and/or
A2 (5) > 1.11 U N
LED ON green
Monitoring system is
active and 400 V supply
voltage is connected to
1-5 or A1-A2.
C = output contact
Normally open 11-14
(6-2) closed.
U Up – mode
If the monitored value is
higher than the
upper limit, and
time T has expired.
U Lo U Up – mode
If the monitored value
of voltage is outside
of the upper or lower
voltage limits, and
time T has expired.
Voltage dips < T do
not result in output
relay switching off.
Switch on
U Lo or U Up – modes
When passing the
hysteresis value.
U Lo U Up – mode
When passing the
U Lo or U Up value.
RESET MEMORY
Pressing “SET/RESET”
> 1 sec.
C = output contact
Normally open 11-14
(6-2) closed.
