Systems Operation, Testing and Adjusting, SENR5832, "Electronic Modular Control Panel II+ (EMCPII+) for MUI Engines", "External Potential Transformer Connections"

The following two illustrations that appear in the External Potential Transformer Connections topic of the referenced publication are incorrect:

• Open Delta Configuration of External Potential Transformers on Three-Wire Delta Generator

• Open Delta Configuration of External Potential Transformers on Four-Wire Wye Generator

These illustrations show an incorrect connection between "Phase B" and "F14". Both of these illustrations have been corrected. The correct illustrations will appear in subsequent revisions of SENR5832. The two incorrect illustrations that appear in the referenced publication should be replaced by the following two illustrations.

Illustration 1	g00584153
Open Delta Configuration of External Potential Transformers on Three-Wire Delta Generator This configuration allows the GSC+ to accurately measure power parameters when loads are unbalanced and when circulating current is present. The following real power phases cannot be determined: phase A, phase B and phase C. The following power factor phases cannot be determined: phase A, phase B and phase C. These phases are not shown on the GSC+ display.

Illustration 2	g00584154
Open Delta Configuration of External Potential Transformers on Four-Wire Wye Generator This configuration does NOT allow the GSC+ to measure all power parameters when loads are unbalanced and neutral current is present. The following real power phases cannot be determined: phase A, phase B and phase C. The following power factor phases cannot be determined: phase A, phase B and phase C. These phases are not shown on the GSC+ display.
