5.
Activate BLOCK binary input and check that the outputs TEMPALM, TEMPLO, ALARM and
LOCKOUT disappear.
6.
Reset the BLOCK binary input.
7.
Ensure that temperature lockout condition exists and then activate the reset lockout input
RESETLO and check that the outputs TEMPLO and LOCKOUT reset.
11.11.2.4
Completing the test
Continue to test another function or end the test by changing the TestMode setting to Off. Restore
connections and settings to their original values, if they were changed for testing purposes.
11.11.3
Breaker monitoring SSCBR
Prepare the IED for verification of settings outlined in section "Testing the IED operation".
The Signal Monitoring tool in PCM600 shows the service values that are available on the Local HMI as
well.
Values of the logical signals belong to the breaker monitoring are available on the local HMI under: Main
menu/Test/Function status/Monitoring/BreakerMonitoring /SSCBR:x
11.11.3.1
Verifying the settings
1.
Connect the test set for the injection of a three-phase current to the appropriate current terminals of
the IED.
2.
If current need to be injected for a particular test, it should be done in the phase selected by the
PhSel parameter.
3.
Follow the sequence for positioning the auxiliary contacts before testing:
POSCLOSE
POSOPEN
4.
Test of CB contact travel time
4.1. 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 open TTRVOP and travel
4.3. Check that TRVTOPAL and TRVTCLAL are activated.
5.
Test of CB status
5.1. Test the set current level defined by AccStopCurr.
5.2. Check the CLOSEPOS output by changing the POSOPEN to 0 and POSCLOSE to 1.
5.3. Check the OPENPOS output by changing the POSOPEN to 1 and POSCLOSE to 0 and also
5.4. Check the circuit breaker is in INVDPOS if auxiliary contacts read same value or CB is open
6.
Test of remaining life of CB

time to close TTRVCL exceed the respective set values (tTrOpenAlm and tTrCloseAlm). The
measured travel time for opening and closing is shown on TTRVOP and TTRVCL respectively.
inject the current in the selected phase slightly lower and higher than AccStopCurr set value.
Only for a current lower than set AccStopCurr should activate the output POSOPEN.
and inject the current in selected phase more than AccStopCurr set value.
