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 be connected between SMVRCV and ULTVTR1 in the Application Configuration tool.
Note: ULTVTR2, SECRSYN1 and VAMMUX2 cannot be used in this configuration.
