Hello, everyone!
The system is GC-MS 7890/5975A, integrated with Gerstel MultiPurpose Sampler (MPS), Thermal Desorption Unit 2 (TDU2) and CIS4 with C506 controller.
I have a problem with TDU2. After placing a tube to TDU and start of analysis, the error is showing up during heating cycle of TDU and when CIS4 cycle working also. Sometimes, analysis run with no any error. Troubleshooting guide in manuals doesn't have a solution for this.
Cable connections have been checked. Reservoir in UPC controller was filled with new coolant solution (ethanol/water 50%).
The error is
""Error: TDU Heater Fault Id=2:Tref> Limit @ TDU""
