Manually move the actuator to the closed position, loosen the limit cam screw with a 4 mm hex key, turn the cam clockwise until a “click” is heard, then tighten the screw; repeat for the open position in the opposite direction.
Swap the wiring of terminals 9 and 10, and also swap terminals 11 and 12; for PCU modules also exchange the P1 and P3 inputs, then recalibrate if needed.
