Description
(Maximum permissible
negative phase angle
MCB)
[-7.0°]
angle between busbar and mains
is below the configured maximum
permissible angle.
Notes
This parameter is only displayed,
if parameter
is
configured to "Phase matching".

Voltage differential
MCB
2
0.00 to 20.00%
[5.00%]
The maximum permissible voltage
differential for closing the mains
circuit breaker is configured here.
Notes
This value refers to the generator
rated voltage (parameter
) and mains rated voltage
(parameter
If the difference between mains
and busbar voltage does not
exceed the value configured here
and the mains voltage is within
the operating voltage window
(parameters
), the "Command: MCB close"
may be issued.
5711
Pos. freq. differential
MCB
(Positive frequency
differential MCB)
2
0.02 to 0.49 Hz
[0.18 Hz]
The prerequisite for a connect
command being issued for the
MCB is that the differential
frequency is below the configured
differential frequency.
This value specifies the upper
frequency (positive value
corresponds to positive slip →
busbar frequency is higher than
the mains frequency).
5712
Neg. freq. differential
MCB
(Negative frequency
differential MCB)
2
-0.49 to 0.00 Hz
[-0.10 Hz]
The prerequisite for a connect
command being issued for the
MCB is that the differential
frequency is above the configured
differential frequency.
This value specifies the lower
frequency limit (negative value
corresponds to negative slip →
busbar frequency is less than the
mains frequency).
5709
MCB sync. with
separate slip
2
On
The MCB is synchronized with an
individual slip frequency (also
negative).
Notes
The setting for the slipping
frequency (parameter
via display is located under
'configure frequency control'.
