IGS-NT-BC-1.2.0 Reference Guide.PDF
Nominal current of the secondary side of the current transformer connected to
the controller terminals labeled IN. The primary side is adjusted by setpoint
Im3/ErFlCurCTp.
NOTE:
The IN terminals can be used either for measurement of earth current or mains
current (mains import). See also the setpoint I/E-Pm meas.
NOTE:
The CT secondary nominal current is adjustable only in IG-NTC and IS-NT. The
IG-NT has the CT secondary nominal current adjusted fixedly to 5A regardless of
this setpoint.
The setpoint is used to adjust the generator voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.0 if the generator voltage is connected directly
to the controller terminals, i.e. without transformers.
NOTE:
Example: if you have transformers with ratio 6000/100V adjust the setpoint to the
value of 60.0.
NOTE:
The range of the generator voltage inputs must be adjusted properly. See the
setpoint Vg InpRangeSel.
This setpoint selects the range of the generator 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:
The 277V range is suitable for both European (230V) and American (277V)
measurement. The range 120V is intended for high-voltage applications where
voltage transformers with 100V secondary range are used or for alternative
American (120V) measurement.
