Logic
2. Activate shortly the set lockout (SETLOCKOUT) signal in the IED.
3. Check that the circuit breaker lockout (CLLKOUT) signal is set.
4. Activate shortly thereafter, the reset lockout (RSTLKOUT) signal in
the IED.
5. Check that the circuit breaker lockout (CLLKOUT) signal is reset.
6. Initiate a three-phase fault
A three-phase trip should occur and all trip outputs (TRLn) should be ac-
tivated. Functional outputs TRIP and TR3P should be active at each fault.
The output CLLKOUT should not be set.
7. Activate the automatic lockout function, set AutoLock = On and re-
peat
Beside the trip outputs, CLLKOUT should be set.
8. Reset the lockout signal by shortly thereafter activating the reset
lockout (RSTLKOUT) signal.
9. Activate the trip signal lockout function, set TripLockout = On and
repeat
All trip outputs (TRLn) and functional outputs TRIP and TR3P should be
active and stay active after each fault, CLLKOUT should be set.
10. Repeat
All functional outputs should reset.
11. Deactivate the trip signal lockout function, set TripLockout = Off and
the automatic lockout function, set AutoLock = Off .
Completing the test
Continue to test another function or end the test by changing the test mode setting to off.
