If this option enabled, the switching state the binary inputs during the last search for
the resonance point are taken into account. change the binary inputs also detected
during the earth fault and the P-coil readjusted the requirements.

ing the fault current curve the left.
If Line also switched-off, another correction -40 100 performed
