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?

Thanks for sharing your knowledge.

I need help on elektronikon display i installed new this week a new elektronikon but it’s show sensor error after checking all parameters and configuration as well.but it wouldn’t help me out.so plz share your review on this subject …old one is working well but if installed on new it’s shows sensor error and dp air filter as well but on same hardware old elektronikon working well….

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.

Elektronikon graphic shows inoperative. Please help

Elektronikon, display Inoperative. Help me please

Same issue Atlas Copco GA 37 , after the main breaker trips , resetted check all contactors and fuses inside are good then checked the power supply voltage for this control panel it show 19 Vac but display shows nothing and start button unresponsive.

AC? There’s your problem – the controller runs on 24VDC. So fix or replace the DC power supply.

Good luck.

Pls. Help me my main controll atlas dryer g18 med sudenly the screen show like that i did check the power and wiring is all ok… Maybe what is the cause?

If it hasn’t already restarted itself, if you shut power down and back up, does this screen come up directly, or is there some intermediate stuff displayed?
Is the actual compressor itself running?

hi, have you solved this problem already? i get this problem too, could you share how to solve this, thanks
