Hello,
Our BACs autosampler (on a Bruker AV400) is producing a "DOWNWARDS MOTION
FAILED" error, which disrupts the queue in ICON (and leaves the lift air on,
sometimes all night!). The advice I was given by Bruker was to clean the
arm. It is not 100% clear to me what specifically needs to be cleaned. In
addition, we are getting this error more and more frequently and I'm having
to clean the arm more and more often. It is not clear that it is really
that dirty!
My method is to take special care to remove the arm, remove the bolts with
an allen wrench and wipe the piston thoroughly with chemwipes and methanol.
I also use q-tips and methanol to swab the o-rings, etc. I'm wondering if
anyone has any more specific advice on how to stop (or at least decrease
the frequency of) these DOWNWARD MOTION FAILED errors.
Thanks
Justin
