4. Failure to stop the motor after the valve reaches its position (overshoot, overtravel): The motor continues to run after the valve is fully opened or closed, until the torque protection triggers a shutdown. Detection method: 1. The position of the on/off limit switches is offset, and triggering does not occur in advance ； 2. Oxidation of limit contacts, poor contact ； 3. The travel adjustment mechanism is loose or slipping ； 4. The limit signal of the control board is invalid. Solution: 1. Re-adjust the travel limit to precisely set the full open and full close positions ； 2. Grind the contacts or replace the limit switch ； 3. Tighten the travel adjustment screw and locking mechanism ； 4. Repair or replace the main control circuit board.
