Hi all we have a 6850 that is intermittently not achieving ready status. The FID detector temperature reads 0, not recognizing gas flows, and a method resolution report shows Configuration Mismatch : Detector, we have resolved the method, saved and error will re appear. In the GC parameters its showing as an FID. Cycling GC power and restarting Chemstation will work, and we can make 3-4 runs or a sequence, but after a random run it will not ready. I checked the small fan/temp probe cables are connected and I removed the electrometer and inspected the detector. All looks clean and well connected.
I suspect its a networking issue, as this GC (GC2) was recently added to our Chemstation via BootP using an external networking switch, its a used GC from another lab and I added it myself. We can run both GCs (another 6850) concurrently. So theres definitely an opportunity for error. Thoughts or comments appreciated!
We have been able to run up to 4 6890 GCs concurrently on the same PC with network switch so unless the switch is bad or one of the network cards, unless the two GCs have the same IP address there shouldn't be a problem.
I would think it is more a problem with the electrometer board communicating with the main board or the gas controller board possibly. Can you switch either of those between the two GCs and see if the problem follows?
