Thank you for your input! I really appreciate it!The problem is probably inside of your Goldline ACW. Depending on the age of your Goldine ACW there are 2 different relay panels. One has removable relays, the other one the relays aren't removable, they are built into the relay pan. If you have the relay pan that the relays are removable you want to look at the CI relay or Cycle inhibit. The wash equipment sends a signal back to the ACW telling the ACW that I'm ready for the next wash. If it doesn't get that signal the ACW will say Car wash busy or some on those lines.If you have the relay pan that doesn't have the removable relays your going to have to send your relay pan into Hamilton and have it repaired. Just hope and pray you don't need a new relay pan they are almost $600.00. Call Hamilton on Monday morning.
It'll have the new style relay panel in it.It’s about 4/5 years old
There may be a toggle switch located inside the goldline that sets the goldline to look for a constant on relay or a pulse. I would first find that switch and try the opposite position from where it is set. It is easy to bump the switch and cause the problem you are describing.
Going forward and back is likely not going to resolve it. I'm going to assume you have a setup using a physical bayplate on the floor and an air hose as the backup air switch. the machine needs to know the vehicle pulled forward and that it has left the bay before that control power will drop low for it to receive the next wash package from the kiosk.
The way they PLC will know is that while the machine is performing the wash, the vehicle is on the bayplates. This is PLC input X24. At the end of the wash, the vehicle will pull forward off the bayplate, so X24 should go off. The vehicle should slowly drive forward, and this should pulse the backup air switch PLC input X25. It should go on, then off again. Next, the front tire should block the tire finder photoeye, PLC input X20. As the vehicle continues exiting the bay, the rear tire should force the same things to happen. X28 on, then off. X25 on, then off. X20 should be on, go off, then back on again. Once this has happened for both the front and rear tires, you should see PLC output Y4 go off, then about 1.5 seconds later, it should come on again. This entire sequence is called "vehicle detect". It must happen IN ORDER. If something happens out of order, it will look like the vehicle is backing up. After it happens in order, it will be ready for the kiosk to send the next signal.
To make it easier, just think 1-2-3-1-2-3. Bayplate is 1. Backup airswitch is 2. Tire photoeye is 3. If something is missing (like the backup airswitch input), that would be 1-3-1-3. Vehicle detect isn't satisfied, so it won't be ready to be armed until the vehicle detect timer times out.
Sounds complicated, but it's all there to prevent vehicle 1 from backing up and stealing vehicle 2's wash, or accidentally starting vehicle 2's wash because someone is hanging out in the dryer too long and backing up for a better dry.
Update and Thankyou for the lead. We ended up resetting our computer box for our DAN system. Things are up and running for the moment anyway. Thank you all for your ideas and leads!!
Thank you!! I appreciate all your help : )If you don't have the bayplate, the concept is still similar. As the vehicle is leaving, the gantry photoeye input should come back on, then the backup photoeye input along with 2 pulses of the tire finder photoeye. The inputs will vary depending on the exact model, but there is an I/O chart inside the electrical cabinet door on the right side.
First place I would look is the tire finder photoeye. Make sure it's clean, and that someone hadn't run over it.
