6.4.7.2 Completing the testContinue to test another function or end the testing by setting the parameterTestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. Ifanother function is tested, then set the parameter Blocked to No under Main menu/Tests/Function test modes/Current/CCRPLD(52PD)/X:CCRPLD for thefunction, or for each individual function in a chain, to be tested next. Remember toset the parameter Blocked to Yes, for each individual function that has been tested.6.4.8 Directional underpower protection GUPPDUPPrepare the IED for verification of settings as outlined in 5.1 "Preparing the IED toverify settings".Values of the logical signals for GUPPDUP are available on the local HMI underMain menu/Tests/Function status/Current/GUPPDUP(37,P<)/1:GUPPDUP.The Signal Monitoring in PCM600 shows the same signals that are available on thelocal HMI.6.4.8.1 Verifying the settingsThe underpower protection shall be set to values according to the real set values tobe used.The test is made by means of injection of voltage and current where the amplitudeof both current and voltage and the phase angle between the voltage and currentcan be controlled. During the test the analog outputs of active and reactive powershall be monitored.1. Connect the test set for injection of voltage and current corresponding to themode to be used in the application. If a three-phase test set is available thiscould be used for all the modes. If a single-phase current/voltage test set isavailable the test set should be connected to a selected input for one-phasecurrent and voltage.Use the formulas stated in Table 2 for the different calculation modes used.The set mode Mode can be found on the local HMI under Main menu/Settings/IED Settings/Current/GUPPDUP(37,P<)/1:GUPPDUP/General.1MRK 504 126-UEN - Section 6Testing functionality55Commissioning Manual
