3.2.9 Binary recording and LED configuration
All the start and operate outputs from the respective protection functions, various
alarms from supervision functions, and important signals from control and protective
functions are connected to a binary recorder. In case of a fault, the binary recorder is
triggered and all the signals connected to the recorder are recorded.
