The Signal Monitoring tool in PCM600 shows the service values that are availableon the Local HMI as well.Values of the logical signals belong to the breaker monitoring are available on thelocal HMI under: Main menu/Test/Function status/Monitoring/BreakerMonitoring/SSCBR:x10.10.3.1 Verifying the settings GUID-962A344D-5F8D-49A6-B3AC-29C7FEED0A3D v41. Connect the test set for the injection of a three-phase current to the appropriatecurrent terminals of the IED.2. If current need to be injected for a particular test, it should be done in thephase selected by the PhSel parameter.3. Follow the sequence for positioning the auxiliary contacts before testing:POSCLOSE 0 1 0POSOPEN 0 0 14. Test of CB contact travel time4.1. Test the set timing defined by OpenTimeCorr, CloseTimeCorr,tTrOpenAlm and tTrCloseAlm.4.2. Change the status of the auxiliary contacts such that travel time to openTTRVOP and travel time to close TTRVCL exceed the respective setvalues (tTrOpenAlm and tTrCloseAlm). The measured travel time foropening and closing is shown on TTRVOP and TTRVCL respectively.4.3. Check that TRVTOPAL and TRVTCLAL are activated.5. Test of CB status5.1. Test the set current level defined by AccStopCurr.5.2. Check the CLOSEPOS output by changing the POSOPEN to 0 andPOSCLOSE to 1.5.3. Check the OPENPOS output by changing the POSOPEN to 1 andPOSCLOSE to 0 and also inject the current in the selected phase slightlylower and higher than AccStopCurr set value. Only for a current lowerthan set AccStopCurr should activate the output POSOPEN.5.4. Check the circuit breaker is in INVDPOS if auxiliary contacts read samevalue or CB is open and inject the current in selected phase more thanAccStopCurr set value.6.
