A lighting condition of RUN

Answer

Because this relay derives the control power from input of the CT secondary current, when the input current falls below about 0.5 A for 2-phase input or about 0.7A for single-phase input, it will light out. When the current is around this range, because of fluctuation of current values, LED (RUN) will lights up/out repeatedly. That is not a failure.
