If double-ended fault locating is not desired, set address 3807 two ended = OFF. The
default setting is ON.
If the fault location is required to be output as BCD-code, set the maximum time period
the data should be available at the outputs using address 3811 Tmax OUTPUT BCD.
If a new fault occurs, the data are terminated immediately even when it occurs before
this time has expired. Allocate the corresponding output relays as stored if a longer
time period is desired for the output. Once a fault occurred the data will be latched until
the memory is reset or a new fault is registered.
