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.
10.12.2.3 Completing the test
GUID-1A0D8AF0-4C48-45E8-B31D-96734ED1A4D2 v2
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.
10.12.3 Breaker monitoring SSCBR
GUID-10D26C82-79FF-4EAD-AE4A-2F2DBE965087 v3
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
10.12.3.1 Verifying the settings
GUID-962A344D-5F8D-49A6-B3AC-29C7FEED0A3D v4
1. Connect the test set for the injection of a three-phase current to the appropriate
current terminals of the IED.Connect the test set for the injection of a two-
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
0 1 0
POSOPEN 0 0 1
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
