    Wiring options

    • Two wires and reverse polarity (DC3-6V / DC12V / DC24V)

    1.Connecting SW to OPEN , the valve opens , getting the position ,automatically power off, the valve remain fully open position

    2.Connection SW to CLOSE , the valve close , getting the position ,automatically power off, the valve remains side passes position(fully closed)

    • Three wires and two control points (DC3-6V / DC12V / DC24V)

    1. Connecting SW to OPEN, the valve opens , getting the position ,automatically power off, the valve remain fully open position

    2. Connection SW to CLOSED, the valve close , getting the position ,automatically power off, the valve remains side passes position (fully closed)

    Note:AC24V/AC220V can only be used for 50K series electric valves

    • Three wires and one control point (DC3-6V/12V /ADC9-24V /AC220V)

    1.Connecting SW, the valve opens , getting the position ,automatically power off, thevalve remain fully open position

    2.Disconnecting SW, the valve close , getting the position ,automatically power off, the valve remains side passes position (fully closed)

    Note:When power is DC voltage and Red Wires is “+”,Blue wire is “—”

    • Two wires and power off return (DC3-6V/ADC9-24V/AC220V)

    1.SW connecting, the valve open, getting the position and the power off automatically, the valve remains fully open/close position

    2.SW disconnecting, the valve close, getting the position and power off automatically, the valve remains fully open/close position

    • Five wires micro conntroller with signal feedback (DC3-6V/12V/24V)

    1.Connecting SW and OPEN, the valve opens, getting the position green wire output the OLS signal, the controller tests the signal OLS, connect SW to STOP, the valve stops and remains fully open position

    2.Connecting SW and CLOSE, the valve close, getting the position red wire output the CLS signal, the controller tests the signal CLS, connect SW to STOP, the valve stops and remains fully close position,

    Note:Please make sure the signal wires "red", "black" and "green" be connected at first, then connect the power wires " yellow" and "blue".
