ABB 615 Series - Signals

Example 1
The protection operation time is 0.5 seconds, the Fourth delay in SOTF parameter is set
to "1" and the Str 2 delay shot 4 parameter is 0.05 seconds. The protection pickup signal
is connected to the DEL_INIT_2 input.
If the protection picks up after the circuit breaker closes, the fast trip follows after the set
0.05 seconds. The total trip time is the protection pickup delay + 0.05 seconds + the time
it takes to open the circuit breaker.
