PID control (for precise stability) or On/Off control (for simpler tasks).
| Error Code | Meaning | Fix from Manual | |------------|---------|----------------| | HHH | Sensor input > maximum range | Check thermocouple wiring (polarity). Replace sensor. | | LLL | Sensor open or below min range | Test continuity. If Pt100, check for 3-wire bridging. | | Er1 | Internal EEPROM fault | Power cycle. If persists, return for calibration. | | Er2 | Output short or overcurrent | Disconnect load. Test SSR/relay with multimeter. | | no | No sensor detected | Check connection at terminals 4, 5, 6 (for RTD). | xmtg2000 temperature controller manual pdf top
: For a thermocouple, the positive (red) wire often connects to terminal 18 and the negative (blue) wire to terminal 19 . PID control (for precise stability) or On/Off control
Understanding these basics ensures you don't damage the unit or your heating element: | | LLL | Sensor open or below min range | Test continuity
