APPLICATION NOTES
GEK-106273L
MIF Digital Feeder Protection
17-3
LOGIC#3:
After re-closing the breaker, the logic must count the Reset time, to determine if the fault has disappeared or if it still
exists.
If the fault exists, the relay will trip again and the recloser will go to LOCKOUT, as only one shot is required.
Timer in LOGIC#3 counts the reset time, set to 10 seconds.
LOGIC#4:
While the output from LOGIC#3 is active, while the reset time is being counted down after re-closing the breaker, if
the relay trips then the 79 is sent to Lockout and output B9 is closed and latched.
B9 also activates input A9 to avoid new reclosing attempts.
