11.10.3.9 Completing the test SEMOD175185-374 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.11.10.4 Single command, 16 signals SINGLECMD SEMOD172444-5 v3For the single command function block, it is necessary to configure the outputsignal to corresponding binary output of the IED. The operation of the singlecommand function (SINGLECMD) is then checked from the local HMI byapplying the commands with Mode = Off, Steady or Pulse, and by observing thelogic statuses of the corresponding binary output. Command control functionsincluded in the operation of different built-in functions must be tested at the sametime as their corresponding functions.11.10.5 Interlocking M11755-2 v8Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".Values of the logical signals are available on the local HMI under Main menu/Tests/Function status/Control/Apparatus control/Interlocking. The SignalMonitoring in PCM600 shows the same signals that are available on the local HMI.The interlocking function consists of a bay-level part and a station-level part. Theinterlocking is delivery specific and is realized by bay-to-bay communication overthe station bus. For that reason, test the function in a system, that is, either in acomplete delivery system as an acceptance test (FAT/SAT) or as parts of thatsystem.11.11 Scheme communication SEMOD53569-1 v111.11.1 Scheme communication logic for distance or overcurrentprotection ZCPSCH M13868-2 v7Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".Check the scheme logic during the secondary injection test of the impedance orovercurrent protection functions.Activation of the different zones verifies that the CS signal is issued from theintended zones. The CS signal from the independent tripping zone must have atSendMin minimum time.1MRK 504 165-UEN A Section 11Testing functionality by secondary injectionTransformer protection RET670 2.2 IEC 247Commissioning manual
