[RASMB] XL-I Diagnostic 61 Error: Drive Malfunction

[John J. Correia]

Ron, we had occasional 61 errors that cleared when we turned everything off. It came with other random errors that never persisted. In our case after many months the solution was replacing the Eproms which were old ( > 6 or 7 yrs)?  Knock on wood it has worked thus far…

Subject: [RASMB] XL-I Diagnostic 61 Error: Drive Malfunction

Hello members!

I was wondering if any of you have experience with the Diag 61: Drive malfunction error on the XL-I. Beckman says it will take a month to get an engineer out and I'm wondering if it's something I could resolve myself, as we have samples that need to be run.

The error displayed on the machine is as follows:
Diag 61: Drive malfunction. Door will remain closed for one hour

>From what I've gathered so far, this may be a failure of the machine to sense the rotor, and it wants to wait an hour because of the danger that the rotor may still be coasting in the vacuum. However, even after several hours the error message will still not clear and allow the door to be opened.

After turning off the machine and releasing the vacuum and the door manually, I have seen that the rotor is not still spinning, however even after returning the vacuum screw to its original position and turning the machine back on with the rotor in the chamber, the error will not clear.

The relevant log files are as follows, thank you all in advance for any advice or tips you may have!
