function blocks can also be individually blocked to ensure that no events are reported to aremote station during the test. This is done by setting the parameterEvDisable toYes.Any function is blocked if the corresponding setting in the local HMI under Mainmenu/Test/Function test modes menu remainsOn, that is, the parameterBlocked is set toYes and the parameterTestMode under Main menu/Test/IEDtest mode remains active. All functions that were blocked or released in aprevious test mode session, that is, the parameterTest mode is set toOn, arereset when a new test mode session is started.Procedure1. Click the Function test modes menu.The Function test modes menu is located in the local HMI under Main menu/Test/Function test modes.2. Browse to the function instance that needs to be released.3. Set parameterBlocked for the selected function toNo.11.6 Verifying analog primary and secondary measurementM11745-2 v13Verify that the connections are correct and that measuring and scaling is done correctly. Thisis done by injecting current and voltage to the IED.Besides verifying analog input values from the merging unit via the IEC/UCA 61850-9-2LEprocess bus, analog values from the transformer input module can be verified as follows.Apply input signals as needed according to the actual hardware and theapplication configuration.1. Inject a symmetrical three-phase voltage and current at rated value.2. Compare the injected value with the measured values.The voltage and current phasor menu in the local HMI is located under Main menu/Measurements/Analog primary values and Main menu/Measurements/Analogsecondary values.3. Compare the frequency reading with the set frequency and the direction of the power.The frequency and active power are located under Main menu/Measurements/Monitoring/ServiceValues(MMXN)/CVMMXN:x. Then navigate to the bottom of the listto find the frequency.4. Inject an unsymmetrical three-phase voltage and current, to verify that phases arecorrectly connected.If some setting deviates, check the analog input settings underMain menu/Configuration/Analog modules11.7 Testing the protection functionality GUID-125B6F28-D3E5-4535-9CD6-6C056B79F496 v2Each protection function must be tested individually by secondary injection.1MRK 502 067-UEN B Section 11Testing IED operation89Commissioning manual
