Operation
AC Current Sensing
An Input voltage must be supplied to the CJD continuously. With the current adjustment at the desired set point, the internal relay will energize and transfer the output contacts when the current through the C-T on the side of the CJD exceeds the adjustable set point for the time delay. When the current drops 2% below the set point, the internal relay will de-energize after the time delay. Current ranges on the multi-range CJD are selected by jumpers on the socket.
