large tonnage RTAA

Is there a way to lock Compressor b out and run just A

[motoguy128]

Model number would help. Is this a 2 compressor or 3 compressor unit? Are A&B on the same circuit or separate circuits?

I thought in the menu there was an option to disable or take a circuit or single compressor out of service.

We're running a 300T until with just compressor C, since circuit 1 has too many leaks in impossible to fix locations, so its' been abandoned. The building only actually need 100-120 Tons anyway.

Large tonnage AA yes a and b are twinned b and c it a single compressor I know you can lock out circuits but not compressors it is the old black box type controller

Is there a way to lock Compressor b out and run just A

Yes, in the service test menu.

I will cycle through pumpdown cicuits, then EXV test and then lockout circuit A, B,.

Idividual compressors on a tandem (twinned ? ) configuration can be isolated by pulling the control wire.

Is one bad ?

If it's a burnout I wouldnt recomend running it.

I dont like to isolate individual compressors on a tandem assembly after compressor failure.

Large tonnage...

that's vague. what is large to you? what is small?

[klove]

that's vague. what is large to you? what is small?

Large/small, fat/thin, short/tall, smart/stupid, ugly/pretty, normal/weird: all depends on who you're standing next to at the moment.

but what if you're 'pretty ugly' like me?

[milkyway]

Then we shoot ourselves ,

That's a fair question concerning the idiosyncracies of the American English language. Not knowing you personally, I can't comment on how it actually applies in your case......

Well, you could always find somebody uglier to hang around.

I think when he says "large tonnage RTAA" he is referring to the 130 to 400 ton RTAA with the 'UCP1 style' controls as opposed to the "small tonnage RTAA" which would be the 70 to 125 RTAA with 'UCP 2' style controls.

see why I said large tonnage lots easier to say than that.
It was a rental it showed up with a bad transducer and the contractor started it up and the system showed it had gas in it but it was flat and it started one time and one time only haha they said it bogged the genny down so much it about shut off.

[R123]

Do you mean bad temp sensor? The RTAA doesn't have transducers.

This is why people who dont understand RTAAs shouldnt start them up .
No gas , = no lube = metal to metal rotors =dead compressor .
Happy Canada Day.

and the first 10 digits of the model number is even easier and tells us much more.

You have a very good point there. I knew what he meant by large tonnage RTAA. It's a common informal way of describing the machines around here.

Is the blue kool-aid making you a little grumpy, Jay? lol

[Healey Nut]

10 !!!............. I would be happy with the first 7 !!
That blue cool aid is makin you very fussy Jay ??
