Yep. Out there making central Wisconsin a "cooler place" . . .
I'm having trouble with my Evaporative Condenser control code. The fan & pump VFDs don't like it when you turn them on & off repeatedly several times a second. Go figure . . .
Last night, I came within 25 PSI of blowing the system relief valves and venting the entire 50,000lb charge. You would have heard about me in the news.
:o(
Note to Self:
Don't write control code that automatically disables every fan & pump on the condenser. Sheesh!
I guess I had a "Microsoft Moment" . . .
*Cool*. :o) {sorry, couldn't help myself...}
I must admit the very notion anyone would have to *try* making Wisconsin a "cooler" place -- especially in November -- really sounds absurd. {g}
Was up last weekend as you know, and KnI had to *chistle* the frost off the car windows at 6:45AM before we could leave for Allenton.

Go figure myass, those are compressors you're *toggling* & yea, I'd imagine one could wreck 'em doing that.
Just as one would ruin any AC, refridg, or other types of compressor driven devices where the initial I inrush draw is high (~they say 300% or *more* of normal operating I, y'know) in order to get the things cranking.
I know I'm talking to a controls genius & all, and that since I retired (7 years ago at 44) my skills insofar as controls engineering go are minimally rusty -- if not altogether *obsolete* -- but what the hell, if I'm off base on my theory you can always sue me. ;^)
OK at the risk of sounding like a complete moron, have you considered constructing a "debounce circuit" condition -- using soft timer(s) possibly on the MCR rung -- so even an idiot cannot toggle; UNLESS, an engineer over-rides the "debounce timer" manually? (~at their own risk, BTW)
...just a thought.
