active during first fault. No other outputs should be active. Functional outputsTRIP, all TRLn and TR3P should be active during second fault.6. Initiate a single phase-to-earth fault and switch it off immediately when thetrip signal is generated for the corresponding phase. Initiate the second single-phase-to-earth fault in one of the remaining phases within the time interval,shorter than tEvolvingFault (default setting 2.0s) and shorter than the dead-time of SMBRREC, when included in the protection scheme.Check that the second trip is a three-phase trip and that a three-phaseautoreclosing attempt is given after the three-phase dead time. Functionaloutputs TRIP, TRLn and TR1P should be active during first fault. No otheroutputs should be active. Functional outputs TRIP, all TRLn and TR3P shouldbe active during second fault.7. Initiate a phase-to-phase fault and switch it off immediately when the tripsignal is issued for the corresponding two phases. Initiate a second phase-to-phase fault between two other phases within the time interval, shorterthantEvolvingFault (default setting 2.0s).Check, that the output signals, issued for the first fault, correspond to a two-trip for included phases. The output signals generated by the second faultmust correspond to the three-phase tripping action.13.11.1.4 Circuit breaker lockout SEMOD54375-170 v11The following tests should be carried out when the built-in lockout function is usedin addition to possible other tests, which depends on the complete configuration ofan IED.1. Check that AutoLock and TripLockout are both set to Off.2. Activate shortly the set lockout (SETLKOUT) 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 TRL1, TRL2, TRL3should be activated. Functional outputs TRIP and TR3P should be active ateach fault. The output CLLKOUT should not be set.7. Activate the automatic lockout function, set AutoLock = On and repeat.Besides the TRIP outputs, CLLKOUT should be set.8. Reset the lockout signal by activating the reset lockout (RSTLKOUT) signal.9. Activate the trip signal lockout function, set TripLockout = On and repeat.All trip outputs (TRL1, TRL2, TRL3) and functional outputs TRIP and TR3Pmust be active and stay active after each fault, CLLKOUT should be set.10. Reset the lockout.All functional outputs should reset.11. Deactivate the trip signal lockout function, set TripLockout = Off and theautomatic lockout function, set AutoLock = Off.1MRK 502 073-UEN A Section 13Testing functionality by secondary injectionGenerator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 253Commissioning manual
