8.1.2 Preparing the IED to verify settings M11741-2 v11If a test switch is included, start preparation by making the necessary connectionsto the test switch. This means connecting the test equipment according to a specificand designated IED terminal diagram.Put the IED into the test mode to facilitate the test of individual functions andprevent unwanted operation caused by other functions. The busbar differentialprotection is not included in the test mode and is not prevented to operate duringthe test operations. The test switch should then be connected to the IED.Verify that analog input signals from the analog input module are measured andrecorded correctly by injecting currents and voltages required by the specific IED.To make testing even more effective, use PCM600. PCM600 includes the Signalmonitoring tool, which is useful in reading the individual currents and voltages,their amplitudes and phase angles. In addition, PCM600 contains the Disturbancehandling tool. The content of reports generated by the Disturbance handling toolcan be configured which makes the work more efficient. For example, the tool maybe configured to only show time tagged events and to exclude analog informationand so on.Check the disturbance report settings to ensure that the indications are correct.For information about the functions to test, for example signal or parameter names,see the technical manual. The correct initiation of the disturbance recorder is madeon start and/or release or trip from a function. Also check that the wantedrecordings of analog (real and calculated) and binary signals are achieved.Parameters can be entered into different setting groups. Make sureto test functions for the same parameter setting group. If needed,repeat the tests for all different setting groups used. The differencebetween testing the first parameter setting group and the remainingis that there is no need for testing the connections.During testing, observe that the right testing method, that corresponds to the actualparameters set in the activated parameter setting group, is used.Set and configure the function(s) before testing. Most functions are highly flexibleand permit a choice of functional and tripping modes. The various modes arechecked at the factory as part of the design verification. In certain cases, onlymodes with a high probability of coming into operation need to be checked whencommissioned to verify the configuration and settings.1MRK 511 425-UEN A Section 8Testing IED operationBay control REC650 2.2 IEC 55Commissioning manual
