active. All functions that were blocked or released in a previous testmode session, that is, the parameter Test mode is set to On, are resetwhen 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 parameter Blocked for the selected function to No.10.6 Verifying analog primary and secondarymeasurement M11745-2 v13Verify that the connections are correct and that measuring and scaling is donecorrectly. This is done by injecting current and voltage to the IED.Besides verifying analog input values from the merging unit via the IEC/UCA61850-9-2LE process bus, analog values from the transformer input module can beverified as follows.Apply input signals as needed according to the actual hardware andthe application 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 Mainmenu/Measurements/Analog primary values and Main menu/Measurements/Analog secondary values.3. Compare the frequency reading with the set frequency and the direction of thepower.The frequency and active power are located under Main menu/Measurements/Monitoring/ServiceValues(MMXN)/CVMMXN:x. Thennavigate to the bottom of the list to find the frequency.4. Inject an unsymmetrical three-phase voltage and current, to verify that phasesare correctly connected.If some setting deviates, check the analog input settings underMain menu/Configuration/Analog modules1MRK 505 378-UEN A Section 10Testing IED operationLine differential protection RED670 2.2 IEC 93Commissioning manual
