Thermocouples (K, J, E, S, T) and RTDs (Pt100, Cu50).
Cause: PID parameters are poorly tuned for the thermal mass, or the control period () is too high.
The controller will flash At and run through several heating/cooling cycles to calculate the best P, I, and d values. 4. XMTG-2000 Troubleshooting xmtg-2000 temperature controller manual pdf

The XMTG-2000 is a capable controller once you understand its parameter structure. – especially when configuring input type and PID parameters. Bookmark this guide, download the official manual, and always test with a low-power load first. Thermocouples (K, J, E, S, T) and RTDs (Pt100, Cu50)
Up to two configurable relay alarms (1A/250VAC). Terminal Wiring Diagram and Connections
Proper wiring is critical for safety and accuracy. While specific terminal numbers can vary by brand, a typical XMTG-2000 configuration includes: Often connected to terminals 9 and 10 . – especially when configuring input type and PID
If AT gives poor results (e.g., slow heating or cycling), use these rules from the manual:
, the 2000 series is more "old-school." It lacks the advanced time/temperature ramping (soaking) capabilities of the 7000 or
