Laser and Chiller problems

I am hoping someone has some ideas for me to check because I am at a loss. I have a FS Pro Laser that I converted to a Ruida and Lightburn machine. I have an Omtech CW-5202 chiller.

I was using it this morning with no problems, but I had to run errands so I shut it down for about 2 hours and when I turned it on again, the alarm on the chiller won’t shut off. I checked the water level, water flow, water temp, all are working fine. I tried running a short job even thought the alarm was sounding, but the laser wouldn’t fire. It would run through the the motions, but not actually fire.

Any ideas where to look?

If connected properly, the chiller is wired to the controller, not the lps. That would prevent the lps from being enabled and consequently no lase.

Really depends on how you have it wired. How is the chiller connected to the co2 machine?


There’s a pretty low cost controller in the 5202 machine. It’s more likely that there is a controller issue with the chiller.

Here’s a couple of manuals that might help.

The CO2 machine has a specified spot for the chiller. It has been connected there for years. I doubt it is a wiring issue. The chiller board is certainly more likely. The chiller is about 2 ½ years old.

There are multiple answers to the same issues, without knowing how it’s wired I have to guess.

If the chiller is connected to the laser, does the machines console show a water protection or any other type of error?

What I should do, I guess, is treat these as separate problems. Fix one then go to the other.

The chiller problem occurs whether or not it is connected to the laser.

You might find out if you fix the chiller, then the laser might also work… meaning there was only one problem.


If you need help or have questions, don’t hesitate to sing out.

Update: The chiller is the issue. Some sort of malfunction in the board.
