Technical Manual 3-Wire, 2-Control Mode – Adjustable Power Failure Reset Operating Voltage: AC/DC 9–24V 1. Specifications Control Type: 3-wire, 2-control mode Power Failure Reset: Adjustable Operating Voltage: AC/DC 9–24V 2. Wiring Diagram Connect the black wire (BK) as the common line. Use red wire (RD) to initiate the Close function. Use yellow wire (YW) to initiate the Open function. External switch (SW) selects open/close command. 3. Operating Instructions 3.1 Opening the Valve When the switch (SW) is connected to the yellow wire (OPEN), the valve begins to open. Once the valve reaches the fully open position, the internal power supply automatically shuts off. The controller remains in the open state until the next command is given. 3.2 Closing the Valve When the switch (SW) is connected to the red wire (CLOSE), the valve begins to close. Once the valve reaches the fully closed position, the internal power supply automatically shuts off. The controller remains in the closed state until the next command is given. 4. Notes Ensure the power supply is within the rated range (AC/DC 9–24V). Do not connect both open and close control wires simultaneously. The actuator automatically stops when the end position is reached, preventing motor overload. For safety, disconnect power before wiring or maintenance.
