Your machine was built to include both ClearCoat as well as Surface Sealant (RainShield). To make this work properly, you need to have timer D874 set to a value of 2. This will allow the clearcoat to be actuated by PLC output Y42 using relay K90, and your Surface Sealant to turn on through PLC...

Not sure what you are chasing with your equipment, but if two devices aren't communicating, that is always a good place to start, as well as verifying connections are corroded, etc.

All, just a quick follow-up if you are following this thread: The AMTT losing it's program appears to have been caused by a minor crack in the bitmap socket on the AMTT. As it expands and contracts, this would cause it to lose programming The rearming appears to have been caused by an...

The AMTT issues and the carwash issues shouldn't be related. For the AMTT losing it's program, you mentioned you had replaced the board. power down, and look really closely at the main CPU board. Specifically, the program and bitmap IC chips go into the sockets U17 (program) and U8 (bitmap)...

The first thing I would recommend is to go into diagnostics in the AMTT, and go into the network diagnostics option. I'd begin with the Network SBX test (this tests the comm board in the AMTT), then run the PLC network test (this tests comm to the PLC node). If the PLC network test fails, it...

I read the technician comments, and looks like the boost pump circuit protector had been tripped causing the issues with the ColorWave, and it was a bad injector on the RainShield. Is it working properly now?

Yes, I'm still thinking pinched lines. That seems more likely than 2 failed injectors. When you disconnect that line and just use a short one headed to a bucket, you are taking out any back pressure further upstream. If your injectors are providing chem into the bucket, that way, they are fine.

If you remove the 1/2" polytube coming off the injector that routes through the boom and you start getting chem out the injector, you have too much back pressure somewhere further down the line. If it just started happening, it's most likely something like a pinched line somewhere in the boom...

Is the boost pump turning on, and if so, what pressure is it running at? Are you getting water at the nozzles or from the Colorwave manifold?

Looks great! Thank you for your business, and I hope the machine runs well for you!

You need to monitor your 24VAC side at the point in time when the top brush should begin to spin. For the top brush, check between wire 10 (24VAC hot for that section of outputs), and wire 25 common. If you are less than around 22.5VAC, it's likely not enough to pull in the contactor and you...

If the machine is stopping mid-cycle, it will generate a 2 digit code. I've sent you a PM with some other ideas to try to diagnose the issue.

Does your machine have a touchscreen controller, or is it the older 2 digit display? When the machine stops at the rear, it could be a number of different things. If you have a touchscreen controller, please go into the diagnostics history and send me a list of what is shown. If you have a 2...

I'm actually the one that found that old Voyager video for you. I looked for the R7B, but couldn't find one. Was surprised to find that one! Amazing how far all the manufacturers have come!

The valve is our P/N 18318-007 and is a 1" Lexair valve. We do have a repair kit (P/N 18318-812 that contains a poppet w/o-ring, u-cup, static seal and the assembly tool available for repairs.

It sounds like the front endstop prox input may be coming on (PLC input X7), and when it happens, it thinks it is at home position so it decelerates until it stops.

The valve Y5 should be a water valve for a rocker panel blaster, but an undercar could have been plumbed to it.

From the output of the 25HP pump, it feeds the undercar valve Y12 (plc output Y44) and the high impact to arm solenoid for valve Y4 (plc output Y50). It just sounds like the UC valve may have too much pressure behind it to fully seat until it either bleeds down, or the arm valve kicks in. You...

On a Ryko, we are looking for the loss of the bayplate before we see the tire and backup airswitch pulses. This is how we can tell direction of travel, and if that sequence occurs twice, we know the vehicle has exited. We did have to modify our program logic when we developed a photoeye...

During the wash, in most systems it should be that simple. You may run into issues at the end of the wash though when the PLC is trying to recognize the vehicle has left the bay and is ready for the coinbox to arm for the next vehicle in line. On Ryko equipment, we use the loss of bayplate as...
