SyncLostMode is not required to set as Block/BlockonLostUTC when differential
protection based on ECHO mode. A missing PPS however will lead to a drift between
MU and IED. Therefore protection functions in this case will be blocked.
Functions can be blocked by loss of analog data, for example if a IEC/UCA
61850-9-2LE source malfunctions. Figure
malfunctions, and all function blocks connected to that 3-phase group get blocked as a
result, this is also known as conditional blocking functionality.
