Our autosampler 1260 freezes when running a sequence but not for an individual run.  Why?

It would be very tricky to troubleshoot your problem without having more details. What is the model number, which firmware are you running, which CDS, which drivers etc. What exactly happens and when?

Beside from gathering those details and get in touch with your local customer contact center, I would suggest you try a forced cold start. This can be done from LabAdvisor or with the DIP switches at the rear of the module. Depending on the so-called platform the sampler is based on, your module will have either six or eight DIP switches, Turn off the module, put DIP switches 1, 2 and 6 (or 1, 2 and 8, if you have eight switches) to the upper position. Turn on the module and wait about 30s. Turn off and bring all DIP switches to their original position. Then check if the issue is gone.
