Monitoring
(Limit 1/Limit 2)
2 [On]
Overfrequency monitoring is carried
out according to the following
parameters. Monitoring is performed
at two levels. Both values may be
con󰈡gured independent from each
other (prerequisite: Level 1 limit
< limit 2).
O󰈠 Monitoring is disabled for Level 1 limit
and/or Level 2 limit.

Limit
(Limit 1/Limit 2)
2 100.0 to 130.0 %
2854: [100.4 %]
2860: [102.0 %]
The percentage values that are to be
monitored for each threshold limit are
de󰈡ned here.
If this value is reached or exceeded
for at least the delay time without
interruption, the action speci󰈡ed by
the alarm class is initiated.
Notes
This value refers to the System rated
frequency (parameter 1750).

Delay
(Limit 1/Limit 2)

[0.06 s]
If the monitored system A frequency
value exceeds the threshold value for
the delay time con󰈡gured here, an
alarm will be issued.
Notes
If the monitored frequency falls below
the threshold (minus the hysteresis)
before the delay expires the time will
be reset.
