Xmta-2c Manual [updated] Jun 2026

Manual PID tuning is difficult. The XMTA-2C includes an function that calculates optimal P, I, D values.

The is a popular, low-cost PID (Proportional-Integral-Derivative) temperature controller manufactured by several Chinese OEMs, including YuDian and RKC rebranded units. It is widely used in:

: The device performs self-diagnosis and will display error prompts if a malfunction occurs. Input Errors xmta-2c manual

This article serves as your comprehensive guide. We will break down the essential information found in the standard manual, translating technical jargon into actionable steps. From understanding the panel symbols to wiring diagrams and PID calibration, consider this your definitive resource for the XMTA-2C.

: If the display shows unexpected readings, check the input signal wiring and sensor type compatibility. CNC Electric Manual PID tuning is difficult

| Symptom | Likely Cause | Fix (from the XMTA-2C manual) | |---------------------------|-----------------------------------|-----------------------------------------| | | Sensor open or polarity reversed | Check wiring; reverse TC leads. | | Display shows LLL | Sensor shorted or below range | Inspect thermocouple for damage. | | Temperature unstable (oscillation) | PID values incorrect | Run auto-tune (At=1). | | Relay chatters rapidly | Cycle time (T) too short | Increase T to 20 seconds. | | PV reads wrong but sensor works | Need offset | Adjust Sc parameter (±5.0). | | Buttons do nothing | Key lock active | Set LCK = 0 . | | Heater stays ON | Output relay failed | Check relay contacts; replace unit. |

The XMTA-2C is designed for stability in demanding environments, such as chemical processing, metallurgy, and laboratory equipment. ±0.5% to ±1.0% of full scale. Power Supply: AC 85-242V, 50/60Hz. It is widely used in: : The device

While the physical units may vary slightly by batch (button colors, terminal numbers), the core menu structure and parameter codes remain standard for the XMTA-2C series.

: Standard relay contact (250V AC/7A) or voltage pulse for solid-state relays (SSR).
