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 secondary measurement
M11745-2 v14
Verify that the connections are correct and that measuring and scaling is done correctly. This is done by
injecting current and voltage to the IED.
Besides verifying analog input values from the merging unit via the IEC/UCA 61850-9-2LE process bus,
analog values from the transformer input module can be verified as follows.
Apply input signals as needed according to the actual hardware and the 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 Main menu /
Measurements /Analog primary values and Main menu /Measurements /Analog secondary
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 list to find the frequency.
4. Inject an unsymmetrical three-phase voltage and current, to verify that phases are correctly
connected.
If some setting deviates, check the analog input settings under
Main menu /Configuration /Analog modules
If the IEC/UCA 61850-9-2LE communication is interrupted during current injection, the
disturbance report tool in PCM600 will display the current that was injected before the
interruption.
