With respect to a chiller motor, what do the abreviations "OLTA", "LRYD" and "LRYA" mean?
Thanks for your help and HAPPY HOLIDAYS!

LRYA-Locked Rotor Y Amps, LRDA-Locked Rotor Delta Amps. OLTA is for the ovlerloads. I think they state Y and Delta values as it is pretty common to use Y/delta starting for centrifugal chillers.

Given the OPs handle, I'd venture to say we have just done his homework for him.
And corrected his abbreviations, possibly?

You engineers with the sharp eye for detail. I didn't notice the typo until you pointed it out.
Well, thank you.
However, I'm not sure whether that sharp eye, if I have such, is a result of my engineering background.
I read a lot, I got punished at school for incorrect spelling, I do cryptic crosswords for fun and I play Scrabble on line with varying degrees of success.
A masochist, maybe.
As Mrs B would readily confirm, I am pernickety about documents that go out from our office. We try to portray a professional image so Kw just doesn't cut the mustard. Nor KW nor kw.
But maybe I'm just a pedantic old bar steward....

Kidding aside, we appreciate your attention to detail and your sense of humor. Merry Christmas

Sense of humour....
Maybe. Besides my day job and my posts here, I'm a bit of a petrol head. Interested in cars, that is. See avatar. Did about 100,000 miles in that sweet V-12.
Somewhat related, I did a bit of Paint Shop Pro to make this bit of humour a bit British.....
Mods, be kind.
