is an intelligent digital temperature controller typically used in industrial applications such as injection molding, food processing, and chemical production. It is designed to replace older analog or pointer-style controllers with precise microprocessor-based PID control. Core Specifications & Features Control Modes : Supports both PID control (with auto-tuning) and ON/OFF control (with adjustable hysteresis). Input Types : Compatible with standard sensors like K, E, J thermocouples Output Options : Commonly available with Relay contact SSR (Solid State Relay) voltage pulse outputs. Auto-Tuning (AT)
: If the display shows unexpected readings, check the input signal wiring and sensor type compatibility. CNC Electric xmta-2c manual
| Code | Name | Setting Range | Explanation | |------|-------------------|-------------------|------------------------------------------------| | | Alarm 1 value | Full range | Temperature threshold for first alarm. | | AL2 | Alarm 2 value | Full range | Threshold for second alarm (if present). | | HY | Hysteresis | 0.1 – 100.0 °C | Deadband for ON/OFF control; prevents relay chatter. | | P | Proportional band | 0 – 999.9 °C | P=0 activates ON/OFF control; >0 enables PID. | | I | Integral time | 0 – 9999 sec (0=off) | Eliminates steady-state error. | | D | Derivative time | 0 – 9999 sec (0=off) | Anticipates future error; dampens overshoot. | | T | Cycle time | 1 – 100 sec | Relay output: 20 sec typical; SSR: 2 sec. | | Sc | Sensor correction | -100.0 – +100.0 | Offset to compensate for probe inaccuracy. | | LCK | Key lock | 0 – 2 | 0: Unlock; 1: Lock SV only; 2: Full lock. | | InP | Input type | See table below | Matches controller to your sensor (K, J, Pt100). | | dP | Decimal point | 0 / 0.0 / 0.00 | Resolution of PV display. | | At | Auto-tune | 0 / 1 | Set to 1 to start self-tuning (resets to 0 after). | Input Types : Compatible with standard sensors like

The basic XMTA-2C lacks a built-in ramp function. However, you can simulate it by manually increasing SV in steps or using an external PLC.
