No TRIP signal should appear.10. Switch off the fault current.11. Reset the RELEASE binary input.12. Switch the fault current on.No TRIP signal should appear.13. Switch the fault current off.11.5.8.2 Completing the test M14922-50 v4Continue to test another function or end the test by changing the TESTMODEsetting to Off. Restore connections and settings to their original values, if they werechanged for testing purposes.11.5.9 Pole discordance protection CCPDSC SEMOD55625-59 v6Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".11.5.9.1 Verifying the settings SEMOD55625-63 v81. External detection logic, Contact function selection = ContSel setting equalsCCPDSC signal from CB. Activate the EXTPDIND binary input, andmeasure the operating time of CCPDSC.Use the TRIP signal from the configured binary output to stop the timer.2. Compare the measured time with the set value tTrip.3. Reset the EXTPDIND input.4. Activate the BLKDBYAR binary input.This test should be performed together with Autorecloser SMBRREC.5. Activate the EXTPDIND binary input.No TRIP signal should appear.6. Reset both BLKDBYAR and EXTPDIND binary inputs.7. Activate the BLOCK binary input.8. Activate EXTPDIND binary input.NO TRIP signal should appear.9. Reset both BLOCK and EXTPDIND binary inputs.10.

Then set inputsPOLE1OPN...POLE3CL in a status that activates the pole discordance logicand repeats step 2 to step 6.11. Unsymmetrical current detection with CB monitoring: Set measured currentin one phase to 110% of current release level. Activate CLOSECMD andmeasure the operating time of the CCPDSC protection.Use the TRIP signal from the configured binary output to stop the timer.12. Deactivate the CLOSECMD: Set measured current in one phase to 90% ofCurrent Release level. Activate CLOSECMD.NO TRIP signal should appear.Section 11 1MRK 505 378-UEN ATesting functionality by secondary injection188 Line differential protection RED670 2.2 IECCommissioning manual
