parameter to "1" and connecting the protection start information to the corresponding
DEL_INIT_ input.
When the function detects a closing of the circuit breaker, that is, any other closing
except the reclosing done by the function itself, it always prohibits shot initiation for
the time set with the Reclaim time parameter. Furthermore, if the Fourth delay in
SOTF parameter is "1", the Str _ delay shot 4 parameter delays are also activated.
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 start
signal is connected to the DEL_INIT_2 input.
If the protection starts after the circuit breaker closes, the fast trip follows after the set
0.05 seconds. The total trip time is the protection start delay + 0.05 seconds + the time
it takes to open the circuit breaker.
