Autosampler arm motor over temp

Hey guys,

The last couple runs, the sequence stopped due to the autosampler arm's motor getting overheated (error code: Motor overtemp [EE 4027, > 70 1da9 5cd20049   0 ).   Are there any steps I can take to fix this issue?  It's a G1313A.



  • Hi B,

    You may need to leave the sampler off too cool down and try again. After you let it "cool down how many injection do you get through?

    What version of software and firmware are you running?

    The transport may be wearing out.

  • Thanks for your help!  We still have the issue, it will run 25 samples, or it may stop at the 4th or 5th.  Regarding the transport, what exactly is that and are there ways to service/clean?

  • It's most likely worn out and needs to be replaced. It is expensive but easy to replace if you are so inclined. The part number is on the top of the transport. Both covers have to come off before you can see the part number, but it should be G1313-60009; updated with new part numberG1329-60009. List price in catalog is almost $2800.

  • Please try procedure as per attached file.

    It will surely help.
