Water Wizard 2.0 - Alarm 9 Drives ran for too long

[oznola38]

I have a Water Wizard 2.0. We have owned it for nearly a year now. We chased a number of issues through last winter but had it running pretty decent. This summer we have had a couple new issues.

1) We are getting "Alarm 9 Drives ran for too long". This only seems to happen with longer trucks. Originally it was happening at the back of the truck. The machine would stop there. Running a test the machine would run until it hit the hard stop at the end of rail. I found that the metal plate on the floor to sense the end of the rail was bent down. I bent it back up and we no longer have this issue. The rail test works correctly now.

Now we get this Alarm when the gantry is back at the front of the vehicle AFTER the complete cycle. It seems it might be when the gantry is moving back to its home location.

I believe this is only happening on our top package (this is the only package with 2 blower passes). Before this started we did change the last 2 passes (blower) to a fast pass then a slow pass (might even be ultra slow).


2) occasionally while pulling in the STOP message will display to the customer before they are anywhere near the front wheel eye. It is after passing the entry eye and the undercarriage blast turning on. I assume it is from the water mist in the air. There is nothing blocking the front wheel eye. Do they get weaker over time?

I believe the gantry has to complete a pass in 60 seconds. As wheels wear down the machine moves a little slower. If only happening on the ultra slow pass on trucks, I would suspect this problem. You can speed your gantry up by either selecting slow speed, or tweak your VFD settings to speed up ultra slow a touch. . Or, put new wheels on it

As far as the eye problem, those eye are pretty strong. They will see through the fleshy part of your hand. Only when they have been n the sun and they have oxidized to complety opaque white have I seen them be a problem. You can try cleaning them with a plastic polish if they are really bad. But I'd honestly be more suspect of a cable connection of that eye. Always replace bad eyes with a replacement that has the long cable attached. My twenty years old wizard is more reliable now than when it was five years old, and I attribute that to the pigtail eyes being replaced with the eyes with the long cable.
