Check your back up hose for holes

I'm using a pressure pad no air and is working 100%.

You have to have a backup hose to signal the customer to backup if they travel further then the pressure pad. Also make sure the photo-eyes are aligned.

They both open and close perfect when the vehicle is exiting maybe the tire size or the eyes adjusted up to high and seeing something low on the cars I dont get this code continuously so it could be low cars I guess. Will watch next car thats in the bay

You are looking at the exit door photo eyes. Check both the "entrance end tire locator" photo eye and the "exit end tire locator" photo eyes. Make sure the pressure pads are in the exact location of where the original bay switch and back up hose were. The machine must also stop in the exact location after every wash. This should be the same unless you end one of your wash packages with a different cycle than one of the other packages. If all of your wash speeds are adjusted with your end stops this is a mute point (every time a wash ends the machine should be within a half inch or closer to the bumper without slamming into it).

actually I was referring to the exit end and enter end photo eyes on the machine one is before the hub scrubber and one is after I have position the bay and backup pads as instructed in my installation manual that I received with the unit the machine starts and stops consistently with every wash no code 49 today . would an ultrasonic sensor be some cause it has a few issues sometimes it's reading 103-120 at rest i have it programmed at 102 and the light on the PLC at times is blinking. Im going to replace it first and see if any change.

Open the electrical panel on the machine. I'm assuming this is a Soft Gloss. Step on the pressure pad closest to the exit (should be the one that is for back-up. Ensure input#25 comes on. Next block the the phot-eye at the rear of the wheel brush input #20 should go off. Next block the photo-eye on the exit side of wheel brush and input #12 should go off. Back-up pad should be about 15" from the entrance side photo-eye. It has to go off before the photo-eye detects the tire, if it does not this is why you are getting the code.

Problem solved after watching a few vehicles wash I notice after trucks no 49 but almost every car set the code and further investigation led me to the photo eys were about a half of inch to high dosent sound like much but adjusted down and works perfect no 49 as for the ultra sonic I didnt think it would have any thing to do with the 49 but have found the some issues are linked to another. as for the untrasonic I continue to have false readings and have one in from ordering just need to pickup and install.
