6 Supervision Functions
Parameter: 50BF-n CB Faulty
•
Default Setting: <None>
This input is connected to the CB monitoring circuits. If this input is operated when a trip initiation is
received an output will be given immediately (the timers are by passed), (see
section 50BF Circuit-Breaker Failure Protection – 3 Pole).
