This setpoint selects the range of the bus voltage terminals. The 120V range is
available only in IG-NTC and IS-NT. The IG-NT has the range adjusted fixedly to
277V regardless of this setpoint.
NOTE:
See all notes mentioned above.
This setpoint is used to adjust the nominal (rated) generator voltage (phase to
neutral). If you do not know the phase-neutral nominal voltage, you can adjust the
phase-phase nominal voltage GenNomVph-ph. The controller will then recalculate
the phase-neutral nominal voltage automatically.
NOTE:
The actual setpoint units and range depend on setting of the Power format in
GenConfig.
NOTE:
If different voltage on gen-set and on Bus/Mains is required the following
procedure is required:
Both setpoints (MainsNomV and GenNomV) must be adjusted to the same values
according to the value of actual generator nominal voltage. E.g. gen-set nominal is
231 V but Bus/Mains nominal is 240 V.
In this case both setpoints need to be adjusted to 231 V and setpoints of
corresponding protections for Bus/Mains need to be set assymetrically.
For 240 V on Bus/Mains it is typical to open MCB when voltage reaches 254 V or
225 V. Since the setpoint is adjusted to 231 V corresponding protection setpoints
need to be adjusted to Mains >V MP = 106% and Mains <V MP = 97 % (hence
the desired values are reached).
This setpoint is used to adjust the nominal (rated) generator voltage (phase to
phase). This setpoint is also recalculated automatically when the phase-neutral
nominal voltage GenNomV is changed.
This setpoint can be used if you know the phase-phase nominal voltage only. The
controller will recalculate the phase-neutral nominal voltage automatically when
this setpoint is changed.
