automatically when this setpoint is changed.
NOTE:
The actual setpoint units and range depend on setting of the Power format in
GenConfig.
NOTE:
If different voltage on BusL and on BusR is required the following procedure
is required:
Both setpoints (BusLNomVph-ph and BusRNomVph-ph) must be adjusted to
the same values according to the value of actual BusL or BusR nominal
voltage. E.g. BusR nominal is 400 V but BusL nominal is 415 V.
In this case both setpoints need to be adjusted to 400 V and setpoints of
corresponding protections for BusL need to be set assymetrically.
For 415 V on BusL it is typical to open BTB when voltage reaches 440 V or
390 V. Since the setpoint is adjusted to 400 V corresponding protection
setpoints need to be adjusted to BusRight >V = 106% and BusRight <V = 97
% (hence the desired values are reached).
12.2.2.9 Setpoint: Nomin current
This setpoint is used for adjusting the maximal allowed current at the busL.
The nominal current is used as the basis (100%) for busL thermal-
overcurrent protection (2POvrldStEvDel), and for short current protection
(BusL2Inom del).
NOTE:
The setpoints BusLeftCTprim and BusLeftCTsec must be adjusted properly
to obtain correct busL current readings.
CAUTION!
The maximum measurable input current to the controller current terminals is
11A.
WARNING!
Do not discconnect the CT terminals from the controller while there is
nonzero current in the CT primary circuit!
