We recently swapped out an EPC from an Agilent 6890 (with 5973 MS) in order to troubleshoot another 6890. Once the troubleshooting was complete the EPC was reinstalled. I now get a FAULT "B det type mismatch" that does not allow the GC to reach a ready state. Other than the 5973 MS, there are no other detectors connected to this GC. How can I fix or clear this FAULT?
