: This indicates an input open-circuit or over-range error. Check if your thermocouple or Pt100 sensor is broken, disconnected, or wired backward.
: Connect the positive wire to the positive terminal and the negative wire to the negative terminal.
Red LEDs displaying the current real-time temperature. xmtg-2000 temperature controller manual pdf
A: The manual’s "Optimization" section covers this. It is likely due to an oversized heater. Go back to the PDF and look for the dF (Damping Factor) parameter. Increase dF from 0.1 to 0.3 to stabilize the reading.
Terminal 3 is typically positive (+) and Terminal 4 is negative (-). It outputs a 12V DC pulse to trigger a Solid State Relay. 3. Alarm Outputs (Terminals 5 and 6) : This indicates an input open-circuit or over-range error
Press and hold the button (or cycle through the parameter menu to locate the AT code). Change the AT value from 0 (Off) to 1 (On).
Based on standard documentation for the XMT-2000 series, the controller generally features: Control Method : Intelligent PID control or simple ON/OFF return difference control : Typically or better. Input Types : Supports multiple sensor types, most commonly K-type thermocouples Output Options : For driving contactors (standard 3A/240VAC). SSR (Solid State Relay) : 12VDC pulse for high-speed, wear-free switching. Red LEDs displaying the current real-time temperature
To prevent accidental modification during standard operational workflows, parameters are split into security tiers managed by lock keys. Level 1: Standard Set Point Adjustments
Solution: Swap the positive (+) and negative (-) wires on the sensor terminal.
Disclaimer: Always follow local electrical safety codes. When in doubt, consult a certified instrumentation technician.
: Verify that the output indicator light on the controller faceplate is turning on. Check your external relay, SSR, or fuse links.
