We need to figure out where the "fatal error is coming from"
What software are you running? What model autosampler do you have?
If you look at the sequence logbook or "open logbook" are there any hard errors pointing to any specific modules?
Do you have anything connected via the 9 pin remote cable or via CAN that is not seen in the software running the system?
Also, do you have an external degasser hooked up to the remote port? If yes, is it red? please remove the remote cable and if that is the cause, then it should error out after 8 minutes.
