WW2 thinks occupied when it isn't (also alarm 108 & alarm 109)

[Rainway]

So we were having issues with our Gold Line cashier, kept saying hopper drop. Not sure if related but when someone pays what happens is it will do the wash fine but once they leave it seems to think the bay is occupied with a car so won't turn light green for next car to enter.

My treadle prox seems fine, reading properly.

I did get alarm 108 (boom safety prox alarm) and alarm 109 (boom prox detected slack). Do you think this is related at all possibly? How do I go about troubleshooting these two alarms?

Thank you for suggestions!

Go back and look at your permanent alarm history and see if there are any others.

I don't know if those alarms will take the unit out of service. If it does try a reset followed by a boom count test. If it passes it might clear it up. keep a close eye on your boom proxes. If one is coming on when its not supposed to it could cause a problem.

Also, how are you determining the treadle eye is fine? You should go read the inputs on the red lion and make sure thats what the PLC is seeing.

Treadle reading fine on the inputs on the red lion. We did learn that we could reset things by flipping the switch in the kiosk between P & A and it lets the next car through. Another car wash buddy said to check the fuse in the ECU that's responsible for resetting the cashier. We checked it and found it's blown. It's a 230v 5 or 6 amp.

So the problem was that the cycle wire on the relay inside the Gold Line autocashier came out (on our system the phoenix clip was gone, and it was a couple wires taped together. Plugged those back into the cycle receptacle and it was back online.
