Xmtd-2201 Manual [top] -

Do not exceed the maximum relay rating (3A inductive load, 1A resistive). For larger heaters, use a contactor.

: Standard Thermocouple or RTD configurable sensor input terminal arrangement. Terminal Block Wiring & Connection Map

Follow the diagram on the side of the unit carefully. Ensure your thermocouple or thermal resistor (like a K-type) is placed away from power cords to avoid electrical interference.

If the temperature is unstable, adjust the proportional band to reduce overshooting. xmtd-2201 manual

Compatible with Thermocouple (K, E) or RTD (Pt100, Cu50) sensors.

| Code | Name | Description | Typical Setting | | :--- | :--- | :--- | :--- | | | Proportional Band | Controls sensitivity. A lower number makes the controller react faster but may cause overshoot. | 10–20 | | I | Integral Time | Eliminates offset (error). | 200–300 | | D | Derivative Time | Prevents overshoot. | 30–50 | | AL1 | Alarm 1 | Sets a high-temperature alarm limit. | Set above max operating temp | | SC | Sensor Correction | Calibrates the sensor if it reads slightly off. | 0 | | Sn | Sensor Type | Selects the sensor input (K, J, T, etc.). | K (Default) |

| Error Code | Meaning | Solution | | :--- | :--- | :--- | | HHHH | Sensor input open (Over-range) | Check sensor wiring. Thermocouple broken? | | LLLL | Sensor polarity reversed (Under-range) | Swap thermocouple wires (Terminal 6 & 7) | | Errr | System fault / parameter corruption | Power cycle. If persists, restore factory defaults (see below). | | --- | No sensor detected | Check for loose terminal screw or broken Pt100. | Do not exceed the maximum relay rating (3A

Slide the controller into the 68×68mm panel cutout and secure it using the provided brackets.

The XMTD-2201 supports multiple standard thermal sensors. Check your specific model suffix or the internal software configuration to match your sensor type. Sensor Type Temperature Range K 0°C to 1300°C E Type Thermocouple E 0°C to 600°C J Type Thermocouple J 0°C to 800°C S Type Thermocouple S 0°C to 1600°C Pt100 RTD Pt -200°C to 600°C Cu50 RTD Cu -50°C to 150°C Front Panel Layout and Interface

Always turn off the system before inspecting wiring or replacing internal components. Alibaba.com For further technical details, you can view the full XMT Series Instruction Manual ControllerMeter wiring diagram specific to a relay or an SSR setup for this unit?

: Input mode compatibility optimized primarily for standard Thermocouples (such as Type K or E). Panel Display Elements and Button Functions

Usually set between 3–6% to prevent excessive temperature overshooting.
