If this protective function is triggered, the display indicates "SyA. overvoltage 1" or
"System A overvoltage 2" and the logical command variable "07.10" or "07.11" will be
enabled.
Refer to ╚═▷ “9.1.1 Triggering Characteristics” for the triggering characteristic of this
monitoring function.
The system A overvoltage Level 2 limit con󰈡guration parameters are located below the
"SyA. decoupling" function menu on the display.

Monitoring 2 [On] Overvoltage 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 2 50.0 to 150.0 %
2954: [108.0 %]
2960: [110.0 %]
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 1766).

Delay
(Limit 1/Limit2)
2 0.02 to 99.99 s
2955: [1.50 s]
2961: [0.06 s]
If the monitored voltage value
exceeds the threshold value for the
delay time con󰈡gured here, an alarm
will be issued.
Notes
If the monitored voltage falls below
the threshold (minus the hysteresis)
before the delay expires the time will
be reset.

Alarm class
(Limit 1/Limit2)
2 Class A/B/C/D/E/F/Control
2951: [A]
2957: [B]
Each limit may be assigned an
independent alarm class that speci󰈡es
what action should be taken when the
limit is surpassed.
