Description
out of range and will be reset if all
phases of L-L and all phases of L-N
are in range.
2-phase
Uses the two lowest/highest
phases for triggering the alarm. If
"1771 Mains voltage monitoring"
is configured to “All”, the alarm
will be triggered if at least two
phases L-L or at least two phases
L-N are out of range and will be
reset if at least two phases of L-L
and at least two phases of L-N are
in range.
3-phase
Uses all three phases (symmetric
condition) for triggering the alarm.
If "1771 Mains voltage
monitoring" is configured to “All”,
the alarm will be triggered if all
phases L-L or all phases L-N are
out of range and will be reset if at
least one phase of L-L and at least
one phase of L-N is in range.

Init threshold
2
0.0 to 200.0%
[80.0%]
The time-dependent voltage 2
monitoring initial threshold is
configured here. If the measured
voltage falls below/exceeds this
threshold, the monitoring
sequence starts and the voltage
threshold will change in time
according to the configured
threshold curve points.
If the measured voltage 2 falls
below/exceeds this curve, the
monitoring function triggers and
the configured relay will energize.

Fallback threshold
2
0.0 to 200.0%
[90.0%]
The time-dependent voltage 2
monitoring fallback voltage is
configured here. If the measured
voltage falls below/exceeds the
voltage configured here for at
least the configured "Fallback
time" (parameter
monitoring sequence will be reset.
Notes
This parameter should always be
configured to a value higher/lower
than the "Init threshold"
(parameter
) for proper
operation.
