Wiring instructions for PH ORP Controller:

Place the controller with the screen facing down on the foam pad.Use a phillips screwdriver to unscrew the screws of the back cover.Take out the cable glands.Insert the cable glands into the reserved hole,tighten the nut inside the rear cover.Loosen the nut on the outside of the rear cover.Insert the power cable into the gland on one side.Pass the pH sensor wire through the other side.Note: Do not cross the power line and the sensor line to prevent the drift of the measurement data caused by interference.The power cable has two ends.The brown live wire is connected to the terminal hole marked "L".The blue neutral wire is connected to the terminal hole marked "N".The pH sensor with temperature has four wire ends and are usually marked with a wire mark.The red wire end is connected to the terminal hole marked "ACT".The black wire end is connected to the terminal hole marked "REF".Two temperature wire ends are connected to the terminal hole marked "TEMP" .Both the left and right sides of the ACT terminals can be inserted, and they should be tightened after insertion.The pH sensor without a temperature unit has two wire ends.Just insert it according to the line mark .After the wiring is completed, close the back cover, tighten the screws on the four corners, and tighten the nuts of the glan head.Turn on the power switch,The pH controller screen will light up.Now it can start to work normally.
