4.8 SMM - Site Monitor Module
Site Monitor Module is an expansion of the RT MCSU-4. It allows the user to monitor status
of equipment that is not a part of an RT power system. It may also be used to monitor other
(third party) DC power systems. Its usefulness can be specially appreciated in remote,
unmanned installations. Using the same communication link and WinCSU-2 monitoring
software it is possible to supervise a number of such sites from a central monitoring station.
Four control outputs are provided in the form of voltage free change-over relay contacts. The
relays can be automatically activated in response to an event on any of the module inputs
(assigned by user), or operated manually from a PC.
Note: If the Site Monitor is to be added to an existing installation with RT Power System,
change of the Controller software may be required. WinCSU-2 software will also need an
upgrade.
