Millennium SC_MAN
Rev 2.0
Introduction
The Galaxy Millennium® SC controller (MSC) brings next generation features of the controller to
plants with legacy rectifiers. It provides integrated control and monitoring of plants with a mixture of
rectifier technologies by interfacing with parallel rectifiers (legacy, non
-
serial rectifiers) as well as all
Galaxy Protocol (GP) serial rectifiers and converters. It provides control, monitoring, and alarm
monitoring functions over a multi
-
drop serial interface that interconnects Galaxy Protocol (GP)
rectifiers, GP converters, Bay Interface Cards (BICs), and other serial devices. Galaxy Protocol
communication is via robust RS
-
485 serial buses. MSC has a plethora of I/O and monitoring options.
It can monitor and control battery plants containing up to 72 GP serial rectifiers, up to 16 serial
converters, up to 32 BICs, and up to 16 parallel rectifiers. A maximum combination of 90 GP nodes can
be directly managed on the rectifier serial bus. MSC performs many functions described more
thoroughly in following sections.
