dear members:
please help me about atlas copco elektronikon ga90 vsd with p.n:1900070102ed01.
the system failure 20 appear in display,i don't know this message error,but i think checksum error is happened and data of time keeper m48t02 missed.in some forum read that elektronikon need reprogramming with elektronikon software (DFM4WIN)but this software not found in web's so i need data files for this elektronikon controller with the same version .please if everybody have binary files for chips of this controller (m48t02-at28c64-m27c256 and m28f101)send me or share it in this forum.
thanks

System failure 20 mean two things.
First DC Over Voltage and second Earth fault so, verify wiring. If nothing obvious contact Atlas Copco.
cs.dk:
If the stupid timekeeper IC battery dies, the compressor will show error 200, not 20.

I've had a topic on the subject long time ago, another member sent me a PM, about flashing the device;
--- Quote ---Even if you put new one or copy one chip reprogramming of the whole elektronikon is needed because they have security and parity test inside every ROM.

thank you very much for reply,sorry do you have data files of atlas copco products(such as ga90 vsd,)?
and do you have manual of software for elektronikon controller?
montarbo:
No programming for your unit is possible by any third part. Only A.C or a registered repair agency.
