The following adjustments must be made to make the system ready for the split phase measuring (example
240/120V AC):
Setting Adjustment Description Adjust to
value
6004 G nom. voltage Phase-phase voltage of the generator 120V AC
6041 G transformer Primary voltage of the G voltage transformer (if installed) U
NOM
6042 G transformer Secondary voltage of the G voltage transformer (if installed) U
NOM
6051 BB transformer Primary voltage of the BB voltage transformer (if installed) U
NOM
6052 BB transformer Secondary voltage of the BB voltage transformer (if installed) U
NOM
6053 BB nom. voltage Phase-phase voltage of the busbar U
NOM
The measurement U
L3L1
shows 240V AC. The voltage alarm setpoints refer to the nominal volt-
age 120V AC, and U
L3L1
does not activate any alarm.
The AGC 100 has two sets of BB transformer settings, which can be enabled individually in this
measurement system.
3.3.3 Three-phase system
When the AGC 100 is delivered from the factory, the three-phase system is selected. When this principle is
used, all three phases must be connected to the AGC-100.
The following adjustments must be made to make the system ready for the three-phase measuring (example
400/230V AC):
Setting Adjustment Description Adjust to
value
6004 G nom. voltage Phase-phase voltage of the generator 400V AC
6041 G transformer Primary voltage of the G voltage transformer (if installed) U
NOM
6042 G transformer Secondary voltage of the G voltage transformer (if installed) U
NOM
6051 BB transformer Primary voltage of the BB voltage transformer (if installed) U
NOM
6052 BB transformer Secondary voltage of the BB voltage transformer (if installed) U
NOM
6053 BB nom. voltage Phase-phase voltage of the busbar U
NOM
The AGC 100 has two sets of BB transformer settings, which can be enabled individually in this
measurement system.
