elektronikon reprogramming

[usefi5961]

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.

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;

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.

sorry,have anyone instruction manual for dfm4win software?please if anyone have it share or send me.
thank's

Never say Never , I can if you need send me a message

I'm actually trying to do the same. I've Elektronikon I and it's broken, it doesn't pull GA7FF screw relays that control the contactors. I replaced the darlington array between the HC08 and the relays, but still the same problem. It looks like the HC08 i/o line that drives the relays is just dead, it never changes its state.

Before I replace the MCU, I would need to get the flash, EEPROM and probably other nv-mem content (hour counters, settings) before I replace the MCU. I'm trying to read it through MON08 interface, but did not manage to connect yet with in-circuit BDM.

I guess the unknown variables here are:
- device power for HC08 during MON08 connection: system or MON08 connection?
- security code
- connection parameters (clock supply, divider, HC08 sub-type etc)

Already did some preliminary debugging from MON08 connection during attempts and it's voltages seemed to be expected. Maybe my data-pin is fried too - or I'm doing something really wrong here.

At least I've learned a lot while getting this far, regardless the final result.

Just fixed one.. replaced timekeepper battery and reprogrammed eprom with universal programmer and final programming with atlas copco software 4 windows. If this case is still open i can help you
