Electric Power Generation AllIntroduction
This Special Instruction provides information about upgrading electric power generator set control mounted panels to the EMCP 4.4 control. The following is a list of the controls that can be upgraded to the EMCP 4.4:
EMCP engine status control (ESC)
EMCP1 (per 7C-1000 Control Panel Chart)
EMCP2
EMCP2+
EMCP3.1
EMCP3.2
EMCP3.3The EMCP4.4 control is intended for applications that require generator paralleling for low voltage applications less than 1000 V. Cat® floor-standing control or switch gear must be utilized for medium and high voltage applications.Proper application of EMCP4.4 paralleling controllers is critical. In various areas of this document, the document will refer to the unit as the generator set or engine. These terms are to be used interchangeably.Reference: Systems Operations Troubleshooting/Testing and Adjusting, UENR1210-01, "EMCP4.3/4.4"Reference: Application and Installation Guide, LEBE0007, "EMCP 4.3/4.4 Generator Set Control"Important Safety Information
