      PU-81 manual says fuse is a T500mA (230V) or T1.0A (120V); I believe the "T" means time-delay to tolerate transformer inrush.

        But then what happens to the problem? Fuse will not cause that symptom.

          I think the problem is when i was cinnecting dimm bulb it will cause some voltage drop and sensor cannot work propper
