Good Day, It's Saturday so I cannot call LNS so I'm trying this. I'm getting an alarm "Positioning Stop Proximity Switch B5 Signal Faulty" In the manual I cannot even locate a B5 switch. They mention and show where B2,3, and 4 are, but never 5. Would anyone have a suggestion what might be going on here? Lifts the new bar up and then it gets this error. Thank you
