Answer

After installation, connect the air supply and 4–20mA signal to the positioner.

  1. Press and hold the “▶” button for 3 seconds to enter the menu.
  2. Select “INITA”.
  3. Press and hold the “●” button for 3 seconds.

The positioner will automatically detect the valve stroke, direction, and optimize control parameters.

When the display shows “FINISH”, press the “●” button to exit.

Some models also support one-key auto tuning by pressing and holding the “O” button for 3 seconds.
