Overview
Introduction There are two controllers available with the GPS 4848/100: the Galaxy 
SCF and the Galaxy Millennium. The SCF mounts inside the cabinet 
and has front access. The Millennium mounts inside the front door with 
the display viewed from the outside.
Both controllers are equipped with a Basic control board for basic 
operations and an optional Intelligent control board that provides 
advanced local and remote monitoring and data acquisition features. 
These control boards monitor each other’s status and issue appropriate 
alarms in the event a failure occurs.
