Hi all,


I have a GC PAL (A200S) autosampler used with a gas bench. I recently replaced the PAL controller with a new one. All the settings on the GC PAL are the same as they were on the old one. The problem I am having is that every time I try to run a sequence the autosampler will move to the correct position, and the black bottom part of the syringe holder will bang on the sample block twice and then I get a message which reads "Collision before Z tolerance." I have changed the z tolerance setting to quite a few other settings, which hasn't helped. Has anyone seen this before, and do you know how to fix this? Thanks in advance for any advice!


Best,

Dana
