function is configured, test it together with the function that operates it. Trig thefunction and check that the counter result corresponds to the number of operations.10.12.6.1 Completing the testContinue to test another function or end the test by changing the Test mode setting toOff. Restore connections and settings to their original values, if they were changed fortesting purposes.10.13 Metering10.13.1 Pulse-counter logic PCFCNTThe test of the Pulse-counter logic function PCFCNT requires the Parameter Settingtool in PCM600 or an appropriate connection to the local HMI with the necessaryfunctionality. A known number of pulses with different frequencies are connected tothe pulse counter input. The test should be performed with settings Operation = On orOperation = Off and the function blocked or unblocked. The pulse counter value isthen checked in PCM600 or on the local HMI.10.13.2 Function for energy calculation and demand handlingETPMMTRPrepare the IED for verification of settings as outlined in section ”Overview “ andsection ”Preparing for test“ in this chapter.10.13.2.1 Verifying the settingsCommon test equipment can be used to determine the injection of current and voltageand time measurement.Verification of EAFACC & ERFACC output1. Connect the test set for injection of three-phase currents and three phase voltageto the appropriate current and voltage terminals of the IED.2. Ensure the instantaneous values of active and reactive power from CVMMXNfunction block are connected to ETPMMTR function block active and reactivepower inputs.3. Enable the EnaAcc setting and set tEnergy as 1 minute.4. Activate the STARTACC input and supply the IED with three phase currents andvoltages at their rated value.5. Check that the ACCINPRG signal appears continuously.6. Note the EAFACC and ERFACCvalue after 1 minute and compare it withcalculated energy value.Section 10 1MRK 511 360-UEN ATesting functionality by secondary injection186 Bay control REC670 2.1 IECCommissioning manual
