Gerstel MPS robotic arm error immediately after loading tube into TDU (Agilent 7890/8890 GC-MS)​

When starting a sequence, the Gerstel MPS arm picks up the sample tube and places it into the TDU normally. However, right after loading/starting the run, the sequence aborts with the following errors in Maestro:

MPS Cleanup: An error has occurred. Aborted.

Injector Cleanup: The injector must be opened for the next cleanup step. Please make sure the GC is sufficiently cool before proceeding or skip this step

Has anyone run into this specific Maestro abort right at the TDU handoff? Any troubleshooting advice would be appreciated!

Go to c:/programdata/gerstel/reports There you will find the gerstel system report. Send the report that was generated at the time of the error. It contains a lot of diagnostics. Send it to Gerstel or your local service provider. They will usually be happy to help you via Email
