11.13.2.3 Testing the gas medium supervision for temperature alarm and temperature
lockout conditions
1. Activate the binary input SENTEMPQ.
2. Consider the analogue temperature input SENTEMP and set SENTEMP to a value higher than
TempAlarmLimit, check that outputs TEMPALM and ALARM are activated after a set time delay of
tTempAlarm.
3. Temperature lockout input SETTLO can be used to set TEMPLO signal.
4. Ensure that binary input SENTEMPQ is activated and increase further the temperature input above
TempLOLimit, check that the outputs TEMPLO and LOCKOUT appear after a set time delay of
tTempLockOut.
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.
11.13.2.4 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.
11.13.3 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
11.13.3.1 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:
POSCLS
POSOPN
4. Test of CB contact operation time
4.1. Test the set timing defined by OpTmOpnCor, OpTmClsCor, OpTmOpnAlmLev and
4.2. Change the status of the auxiliary contacts such that operation time to open OPTMOPN and
