Hello,

Some years ago I bought this KIT of AC sensor to turn relay on when current flows.

Finally have put this together but the problem is the relay is buzzing (50hz or something) when it should just stay on.
What can be the problem? I tried adjusting the trim pots but they do not adjust this. They one adjusts on/off thershold the other who knows what.

Problem solved.

You have to adjust the theshold pot without any load connected !
Still waiting for reply from manufacturer about second pot.
