A lighting condition of RUN
Let me know the light up 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.
