Quoted from Lowrent:
Just unpacked mine. Moat doesn't recognize the ball (switch 36). The switch triggers if I break the opto signal with a pencil though.
Do you have any idea what I could do to adjust the opto switch ?
Check and see if it's aligned with the height of the ball as it passes through it. Pencil test means the circuit is working which is good. Maybe just need to get the height/angle correct
