When SMVRCV is connected to ULTVTR1 in the Application Configuration tool, ULTVTR1 is disconnected from the physical channels U1, U2 and U3 and uses three phase voltages from the received IEC 61850-9-2 LE sample value. All functions which have 3U input begin working with the IEC 61850-9-2 LE sample value.

Note: All three signals UL1, UL2 and UL3 must always be connected between SMVRCV and ULTVTR1 in Application Configuration.
Note: The IEC 61850-9-2 LE stream always contains UL1, UL2, UL3 and Uo. When the three phase voltage channels are received from IEC 61850-9-2 LE, the setting VT connection in Configuration > Analog inputs > Voltage (3U,VT) must be “Wye”.
