atlas copco seqencer es8

hello gays

I have five atlas copco compressors connected in canbus with ES8 Sequencer, one day one controller burned and replaced by another one same type and same address but the sequencer warm me that there is new controller found in the network i don't know how to overcome this issues, any help?

You need the user's manual. Have you tried atlas copco website for the download?

i can not found user manual any where , i have only instruction book

I tried too, couldn't find a thing. Have you got an Atlas distributor near you, or you might try calling them directly.
