What means Atlas Copco Error code ST2?

by Collins
(Columbus, Ohio.)

I have 2007 Atlas copco diesel air compressor model XAS 375 with john deer T3 engine (model 4045hf285).


It was running good until a red light turns up on the dash and it stopped.

We had tried every thing to fix it but, it wouldn't start again. It was diagnosed and error message code ST2 came up.

I have no idea what it means, Can you help to decode the meaning of Code ST2.

We have double checked all the fluid levels and they gauged up fine.

Thanks,

ATLAS COPCO XAS 756 error code "engine not responding"

ATLAS COPCO XAS 756 Portable Diesel -error code-"engine not responding

Fluid Level all OK. Radiator clean and degreased flowing well.

No problems with Caterpillar 200hp diesel engine.

But error code on display states..."engine not responding"

Will run loaded for 20 mins then shuts itself down.

What the heck is going on here?

Sounds like it may have a bad tach, where the controller is expecting a change and either doesn't see it at all, or sees it responding out of normal range. May be it's heat related.

VSD

You are trying to get an answer from tech support from Atlas Copco itself, that's going to be extremly hard to get.

You might want to give more details about your problem here, instead.

Those VSD "variable speed drive" compressors are something else.

Is it a MK4 or MK5 controller?

Is it using a NEOS?

Maybe it has a different drive, like a Yaskawa or an ABB, or perhaps a Siemens.

It could be a communication error. Between the controller and the VFD.
