SFT2841: control matrix.<br />
PCRED301005EN - 06/<strong>20</strong>08<br />
Control matrix<br />
The control matrix is used for simple assignment of the logic outputs and signal<br />
lamps to information produced by the protection units, program logic and logic inputs.<br />
Each column creates a logic OR between all the lines selected.<br />
The following data are managed in the control matrix and may be set using the<br />
SFT2841 software tool.<br />
Data Meaning Comments<br />
All of the application protection functions Protection time-delayed output and additional<br />
outputs when applicable<br />
79 - cleared fault The recloser function has sucessfully reclosed Impulse type output<br />
79 - permanent fault The circuit breaker is definitively open after the<br />
reclosing cycles<br />
Impulse type output<br />
Logic inputs I11 to I14 and I21 to I26 According to configuration If MES114 module is configured<br />
BI transmission Sending of the blocking information to the<br />
following Sepam in logic discrimination chain<br />
O3 by default<br />
TCS Trip circuit fault or mismatching of CB position<br />
contacts<br />
If the circuit breaker / contactor control<br />
function is activated<br />
CB control fault A circuit breaker open or close order has not<br />
been executed<br />
Sensor fault Hardware problem on an MET module or on an<br />
RTD<br />
Pick-up Logical OR of the instantaneous output of all<br />
protection units<br />
Watchdog Monitoring of Sepam operation Always on O4 if used<br />
