Relay pull while\nover-current, relay released while not over-current. Users can use the relay\nCOM, NC, NO three ports to control the external circuit on and off, in order\nto achieve over-current protection. Use the potentiometer to set the\novercurrent protection point, the clockwise adjustment reduces the detection\ncurrent. 1. Measured the wire through the current transformer, connect VCC and\nGND to DC12V power supply. 2. Adjust the potentiometer, when you hear the\nsound of the relay pull (can be measured with a multimeter COM and NO whether\nwas turned on, if connected to the relay means activated), then reduce or cut\noff the current flowing that through the tested wire , if the relay release at\nthis time that over-current protection point has been identified (available to\nmultimeter COM and NC measurement whether is connected, if connected to the\nrelay means been released). 3. When reduce or cut off the current flowing\nthrough the wire , the relay is not released, will still need to continue to\nadjust the potentiometer to find the over-current protection point.
