Could be software, voltage to it, plain broke/failed.

Try checking the power to it, if that’s OK, then a power-off reset. If that doesn’t do it, probably have to call in A-C service.


Unreadable format in elektronikon(r) display

I did not get you properly please explain me how it will happen I checked input supply that is correct.
And I also clean and reassemble the cards of controller . What else I have to do if I m facing this problem?

Actually we have 3 compressor having same problem with elektronikon (r) controller all of them show on display nothing or unreadable format.


3 controllers?

Vijay –

Did they all go down around the same time?

If so, you could be looking a power problem – as in voltage spikes in either the primary power, or possibly extreme RFI from somewhere.

You’d need a oscilloscope to check that, probably.

Similarly, if these are on communications circuits, that could have garbage on it, causing them to overload and fault.

By the way, how old are these units?

Sounds like you’ve been making progress.

Re the controller “old” and “new” just mentioned –

Are they the same model and rev. number? Or different?

Either way it sounds like you just have couple of differently placed inputs, or they are not making contact. If the “new” is otherwise working, you should troubleshoot the two problems as what they are: new.

Good luck.
