Mains Operating Ranges
4.5.3.3.1
General Mains Operating Range
General notes
The mains operating voltage/frequency parameters are used to trigger mains failure
conditions and activate an emergency run.
The mains values must be within this ranges to synchronize the mains circuit breaker. It
is recommended to configure the operating limits within the monitoring limits.
Example
If the mains rated voltage is 400 V, the upper voltage limit is 110 % (of the mains rated
voltage, i.e. 440 V), and the hysteresis for the upper voltage limit is 5 % (of the mains
rated voltage, i.e. 20 V), the mains voltage will be considered as being out of the
operating limits as soon as it exceeds 440 V and will be considered as being within the
operating limits again as soon as it falls below 420 V (440 V – 20 V).
If the rated system frequency is 50 Hz, the lower frequency limit is 90 % (of the rated
system frequency, i.e. 45 Hz), and the hysteresis for the lower frequency limit is 5 % (of
the rated system frequency, i.e. 2.5 Hz), the mains frequency will be considered as being
out of the operating limits as soon as it falls below 45 Hz and will be considered as being
within the operating limits again as soon as it exceeds 47.5 Hz (45 Hz + 2.5 Hz).

Description
5810
Upper voltage limit
2
100 to 150%
[110%]
The maximum permissible
positive deviation of the mains
voltage from the mains rated
voltage (parameter
) is
configured here.
This value may be used as a
voltage limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.09).
5814
Hysteresis upper
voltage limit
2
0 to 50%
[2%]
If the mains voltage has exceeded
the limit configured in
parameter
must fall below the limit and the
value configured here, to be
considered as being within the
operating limits again.
5811
Lower voltage limit
2
50 to 100%
[90%]
The maximum permissible
negative deviation of the mains
voltage from the mains rated
voltage (parameter
) is
configured here.
This value may be used as a
voltage limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.09).
