4. Activate BLOCK binary input and check that the outputs TEMPALM, TEMPLO,
ALARM and LOCKOUT disappear.
5. Reset the BLOCK binary input.
6. Make sure that temperature lockout condition exists and then activate the reset
lock out input RESETLO and check that the outputs TEMPLO and LOCKOUT
reset.

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.

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

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 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.
4.3. Check that TRVTOPAL and TRVTCLAL are activated.
5. Test of CB status
