You need to replace the Sigma Controller itself
by: Carl

There is only one way to fix this, you need to replace the Sigma Controller itself.

You need to contact Kaesar (HPC) and tell them all the details of the compressor (Model, Serial number, pressure settings etc).

There is nothing else you can do I'm afraid.

The controller is the whole part where you turn the compressor on and off. Tthe Sigma controller needs replacing. You need to contact Kaesar

Hi,
Having a critical error on your Sigma isn't good I'm afraid. I work for HPC (Kaesar.)

There are only 2 possible ways of getting rid of this, one being replacing the controller, the other is getting it "K-loaded" which means getting Kaeser in to wipe the software and reinstall, even doing that isn't a guaranteed fix as it could possibly do it again.

Temporarily it sometimes works by turning off at the isolator, leave for 20 minutes and turning back on again. But again, it will possible do it again either straight away or soon after.

This fault wouldn't be because of your update, it can happen at anytime, it isn't often that this happens but when it does, unfortunately it is expensive.

Bene -

Are you trying to update the controller soft/firm ware?

If so, you'll need to work it out with Kaeser, sorry.

I presume this error prevents compressor operation -

Were there any symptoms prior to this?

Anything happened to input power?
