Time-dependent voltage
monitoring is carried out
according to the following
parameters.

No monitoring is carried out.

Characteristic
2
The mains time-dependent
monitoring works with different
characteristics.
[1-phase]
Uses the lowest/highest phase for
triggering the alarm. If "1771
Mains voltage monitoring" is
configured to “All”, the alarm will
be triggered if at least one phase
L-L or at least one phases L-N is
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.

Monitoring at
2
Selects whether the system shall
do over- or undervoltage
monitoring.
[Underrun]
The undervoltage monitoring is
carried out (The monitoring
function triggers if the measured
voltage is below the curve).
Overrun
The overvoltage monitoring is
carried out (The monitoring
function triggers if the measured
voltage exceeds the curve).

Init threshold
2
0.0 to 150.0%
[80.0%]
The time-dependent voltage
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 falls
below/exceeds this curve, the
