Basic Unit and Optional Module



15

To manage your installation

locally!

The keypad and display are used to set the Sepam parameters and protection

functions and to display measurements and alarms.

The advanced UMI does not give access to the matrix (use SFT2841).


Advanced User Machine Interface



16

To make the most of your

Sepam !

The SFT2841 tool may be used to set parameters and protection functions and

«customize» Sepam. It provides the alarm history, disturbance records and

parameter down and uploading.


SFT2841 Configuration Software

4 logic outputs as a

standard feature

a choice of 2 additional

input/output modules:

MES108: 4 logic
