VF3 power failure alarm

[agsy103]

I am getting a power failure alarm a few times a day on my 1994 VF3. The control freezes up and I have to cycle the power to clear. No alarm code is given, just the words 'power failure alarm' as you can see in the image attached. Has anyone had a similar problem and found the source of the problem?

I would google Haas Australia and call the closet hfo near you and talk with tech support.

Did you end up fixing this if so what was the problem?

Thanks

No, it just went away. It usually only happens on hot days. I believe there are some diodes on the powerboard that wear out.
