Vb VT ratio
Bus Voltage Transformers ratio.
Step: 0,1 V / V
0,1 – 500,0 V / V
Range:
Hint:
Set VT ratio to 1,0 if no Voltage Transformers are used.
Vb InpRangeSel
Bus voltage sensing inputs range selection. Available in IG-xxC and IS-NT versions. In standard IG-EE/NT
units only 277 V range available.
GenNomV
Nominal generator voltage (phase to neutral).
Step: 1V
80 – 30000 V
Range:
Force value: Yes
Hint:
The nominal value can be externally changed using Force value function. However, it is intended for
changes between standard nominal voltages only (230 / 120 V) using Force value X source setpoints.
It is prohibited to use another controller values as a source for Force value in this case!!!
GenNomVph-ph
Nominal generator voltage (phase to phase).
Step: 1V
130 – 60000 V
Range:
Hint:
If one of the nominal voltages is changed, the other is automatically adjusted to correspond with the new
value. E.g. if GenNomV is changed to 220 V, the GenNomVph-ph is changed to 220*1,73 = 381 V.
MainsNomV
Nominal bus voltage (phase to neutral).
Step: 1V
80 – 30000 V
Range:
Force value: Yes
Hint:
The nominal value can be externally changed using Force value function. However, it is intended for
changes between standard nominal voltages only (230 / 120 V) using Force value X source setpoints.
It is prohibited to use another controller values as a source for Force value in this case!!!
MainsNomVph-ph
Nominal bus voltage (phase to phase).
Step: 1V
130 – 30000 V
Range:
Hint:
Both Gen and Bus nominal voltages must be set to the same value when no PT is used.
