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...

A lot of sites say "Touchfree Automatic", and "SoftTouch Automatic" on a side by side Thank you for your business, and hope the machine runs well for you!

When you replaced the MAC valve and gauge, did you also replace the regulator for trailing air? If so, it's possible you may not have replaced it with the correct one. Most of the MAC regulators are the standard pressure versions, but for trailing air, it uses a low pressure version, P/N...

If the machine is at the rear and driving towards the front (exit), the rear brushes are controlled by "rear trailing air". If you read the gauge for rear trailing air, it is labelled at 10PSI. On all Ryko rollover machines, the pressure designations in the MAC panels should be considered the...

Depends on how your setup questions are answered, and which application you are doing. Presoak will always be fed from the RO/softwater tank in the pump stand. Valve Y7 in the pump stand feedds the 2HP boost pump and this feeds the appropriate water valve for the chemical being applied. If...

As Waxman said, it could be the boost pump running backward. If it is backwards and run that way for a while, that could also damage the impellor. Is Y7 in the pump stand opening? You could put a screwdriver on top of the coil (while coil is on the valve), so see if you can feel the magnetic...

On the older Rainmaker EnviRO units, we did use the 11219-203 valve. I thought you were talking about the Y7 valve that is the RO/soft water inlet valve that comes off the bottom of the soft/RO holding tank in the pump stand that feeds the 2HP boost pump. Still same concept though. If you...

Q14 is the 5A breaker that supplies the 24VAC hot signal labeled as wire 526 to the PLC that controls PLC outputs Y40 through Y77. If Q14 is tripping when you turn on the presoak test, the three outputs that should be coming on are Y40 (presoak air and water), Y66 for the soft water pump...

In both situations, it depends "when" these happened in the cycle. If they were in the first pass of presoak, the machine is basically using the readings from the ultrasonics to map the vehicle. If it were in one of the subsequent passes, it's more likely mechanical or a prox. In the first...

I would also recommend checking your 24VAC at that point in the wash cycle by monitoring wires 26 and 25. At that point in the wash, the wash water solenoid should be turning off, and the wax/CC water solenoids will be turning on, depending on how your wash package is setup. It's possible you...

If I understand you correctly, the machine does it's pass from front to rear where the brushes close. Machine continues to drive reverse as needed because of the short bay. When the machine starts to drive forward for rinse, the rear arms aren't opening fast enough. Is that correct? The...

Sorry, but can't really speak to "how" something is formulated.
