All Generator Sets With The EMCP II+
Reference: Service Manual Module; SENR5832-01; Electronic Modular Control Panel II+ (EMCP II+) For MUI Engines; Page 148; "External Potential Transformer Connections".
The illustration of the 3-Wire Delta Generator on page 148 and the illustration of the 4-Wire Wye Generator on page 149 have been corrected. The illustrations in Service Manual Module; SENR5832-01 had a connection between phase B and fuse 14. This connection has been removed from both illustrations. The illustrations on page 148 and 149 of Service Manual Module; SENR5832-01 should be replaced with the following illustrations.
Open Delta Configuration Of External PT's On 3-Wire Delta Generator.
This configuration allows accurate measurement of power parameters by the GSC+ including when the loads are unbalanced and circulating current is present. Real power phase A, B, C and power factor phase A, B, C can not be determined and are not shown on the GSC+ display.
Open Delta Configuration Of External PT's On 4-Wire Wye Generator.
This configuration results in less accurate measurement of all power parameters by the GSC+ when the loads are unbalanced and neutral current is present. Real power phase A, B, C and power factor phase A, B, C can not be determined and are not shown on the GSC+ display.
