Presentation User-machine interface MT11102 MT11103 SFT2841: measurement screen. SFT2841: protection function 50/51 setting screen. Expert UMI This UMI is available as a complement to the basic or advanced UMI on the screen of a PC equipped with the SFT2841 software tool and connected to the RS 232 link on the front panel of the Sepam (operating in a Windows environment). All the data used for the same task are grouped together in the same screen to facilitate operation. Menus and icons are used for fast, direct access to the required information. Current operating mode This UMI is the solution suited to occasional local operation for demanding personnel who require fast access to all the information. b display of all metering and operating data b display of alarm messages with the time of appearance b display of diagnosis data such as: v tripping current v number of switchgear operations and cumulative breaking current b display of all protection and parameter settings made b display of the logic status of inputs, outputs and signal lamps. Parameter / protection setting mode Used for the display and setting of all the parameters; input data may be prepared ahead of time and transferred into the corresponding Sepam units in a single operation (downloading function). Main functions performed by SFT2841: b changing of passwords b entry of general settings (ratings, integration period, …) protected by a parameter setting password b entry of protection settings in the same page, protected by a setting password b modification of program logic assignments b enabling/disabling of functions b saving of files. Saving - printing of reports b protection and parameter setting data may be saved b reports may also be printed, by exporting the data into a text file. This UMI may also be used to recover disturbance recording files and display them using the SFT2826 software tool. Operating assistance Access from all the screens to a help section which contains all the technical data required for Sepam installation and use. SFT2841 kit The expert UMI software tool comes in a kit which contains: b 1 CD-ROM with: v SFT2841 software v SFT2826 software for disturbance recording file display b 1 PC/Sepam serial link cord. Minimum configuration required Processor PC compatible, Pentium 133 MHz Operating systems Microsoft Windows 98/NT4.0/2000/XP RAM 64 MB (32 MB for Windows 98) Space on disk 64 MB 7
