Xmtd-2201 Manual ((hot)) Page

The XMTD-2201 is a digital temperature controller widely used in industrial heating and cooling systems. This guide provides a comprehensive breakdown of its features, wiring, and programming. 🛠️ Key Specifications Input Type: K-type thermocouple (standard) or RTD (Pt100). Control Mode: Intelligent PID or ON/OFF control. Output: Relay contact (5A) or SSR drive signal. Display: Dual LED (Process Value and Set Value). Power Supply: 85–264V AC. 🔌 Wiring Diagram & Installation

Before powering the device, ensure the terminal connections match your specific model.

Power Terminals: Connect your AC power source to the designated L and N terminals (usually pins 1 and 2). Sensor Input:

Thermocouple: Connect positive to pin 8 and negative to pin 9. Pt100: Uses pins 8, 9, and 10 (three-wire compensation). Load Output:

Relay Model: Use the COM and NO (Normally Open) terminals to switch your heater or cooler.

SSR Model: Connect the DC output directly to the SSR input terminals. ⚙️ Programming and Parameter Settings

To enter the parameter menu, press and hold the SET key for 3 seconds. Use the ▲ and ▼ keys to adjust values. Basic Configuration

Set Point (SV): Tap the SET key once, adjust the value, and press SET again to save.

Hy (Hysteresis): Used in ON/OFF mode to prevent rapid switching.

P, I, D: These control the responsiveness of the PID algorithm. Advanced Parameters (Passcode: 0088)

Accessing the deeper menu allows for calibration and input changes: Inty: Change the input type (K, S, E, Pt100). Outy: Change the output method. xmtd-2201 manual

SC: Sensor calibration (offset adjustment if the reading is slightly off).

At: Auto-tuning. Set this to "1" to let the controller automatically calculate the best PID values for your system. 💡 Troubleshooting Common Issues

Display shows "EEEE": This usually indicates a sensor error. Check for a broken thermocouple or loose wiring.

Temperature overshoots: The "P" (Proportional) band may be too narrow. Run the Auto-tuning (At) function to fix this.

No output: Check the "AL1" or "AL2" settings; an alarm might be overriding the main control loop. 📋 Safety Precautions Always disconnect power before wiring.

Ensure the sensor is rated for the maximum temperature of your application.

Keep high-voltage power lines separate from low-voltage sensor wires to avoid interference. If you'd like to dive deeper, let me know: Are you using a thermocouple or a Pt100? Are you driving a mechanical relay or an SSR?

Do you need help calculating PID values for a specific process?

I can provide a custom step-by-step programming sequence based on your hardware.

digital temperature controller includes several features designed for industrial and laboratory precision. Based on its technical manuals and specifications, here are the most helpful features: 1. Dual LED Display The unit features a dual-window LED display that shows both the Measured Value (PV) Set Value (SV) The XMTD-2201 is a digital temperature controller widely

simultaneously. This allows operators to monitor real-time temperature fluctuations alongside their target temperature without switching between screens. Made-in-China.com 2. Cold End Automatic Compensation

To ensure high accuracy (typically Class 1.0 or 1.5), the device includes automatic cold-end compensation

for thermocouples. This feature adjusts for ambient temperature variations at the terminal connection, preventing measurement drift and ensuring stable readings in changing environments. Made-in-China.com 3. Multi-Input Compatibility

A key versatile feature is its support for various sensor types, often including K, E, PT100, and Cu50

. This flexibility allows the same controller to be repurposed for different industrial applications, from low-temperature refrigeration to high-temperature kilns (up to 400°C or 1300°C depending on the specific sub-model). 4. Safety and Alarm Functions The XMTD-2201 supports diverse alarm modes , including upper and lower limit alarms

. This is critical for protecting equipment from overheating or ensuring a process stays within a specific thermal window. www.clin-ele.com 5. PID & Control Flexibility Depending on the specific variant, the device offers: PID Control:

Provides precise adjustment to minimize overshoot and maintain a "flat" temperature line. Hysteresis (On-Off) Control:

A simpler mode for heating or cooling where a specific "deadband" is set to prevent the relay from clicking rapidly. Manual/Automatic Switchover:

Allows users to manually override the automated control when troubleshooting or starting a process. AliExpress Quick Technical Summary Standard 72x72mm DIN size for easy panel mounting. Adjustment

I understand you're looking for a manual for the XMTD-2201 (a common temperature controller / PID regulator), but I cannot directly make or give you a physical paper manual — I can only provide information. Print this summary – Below is a condensed

However, here's what you can do to get a paper manual:

1. Print this summary – Below is a condensed version of the key settings from the XMTD-2201 manual. Copy it into a document (Word/Google Docs) and print it.

2. Download the official PDF – Search online for:
   "XMTD-2201 manual PDF"
   Look for results from sites like datasheet.live, manualslib.com, or fotek.com.tw (Fotek makes these). Then print the PDF.

3. Contact the seller/manufacturer – If you bought it from a supplier (e.g., AliExpress, Amazon, or local electronics store), ask them for a printed manual.

Part 5: Deep Dive – The Parameter Menu (The "Real" Manual)

This is where most users get lost. The XMTD-2201 contains a hidden secondary menu for configuring input type, PID values, and alarms.

4. Parameter Configuration (The P Menu)

To access advanced settings, press and hold the SET button for approximately 3-5 seconds until the upper display shows a code (usually LC for Lock) and the lower display shows 0.

Enter the lock code (usually 003 or 001 depending on the firmware) using the arrow keys, then press SET to access the parameter menu.

Common Parameters:

| Code | Name | Description | Typical Setting | | :--- | :--- | :--- | :--- | | P | 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) |

Note: After adjusting parameters, press and hold SET to exit and return to normal operation.

How to Enter Full Configuration Mode:

1. Press and hold SET for approximately 5 seconds until the display shows LC (Lock code).
2. Use ▲/▼ to set the code to 0000 (or 0001 depending on firmware).
3. Press SET again. You are now in the parameter list.

Quick-Reference Cheat Sheet

• Boot to config: hold MODE on power-up.
• Serial defaults: 115200 8-N-1.
• Default I/O states: outputs off, inputs pulled-down.
• Firmware update: serial bootloader → send SREC/HEX → verify checksum.
• Reset to factory: hold MODE + RESET for 10 s.

If you want, I can expand any section into full manual-style text (detailed pinouts, full serial command reference, wiring diagrams, or troubleshooting flowcharts).

If you can confirm the brand (e.g., XINJE, Yudian, RKC, or generic) and exact model suffix (e.g., XMTD-2201, XMTD-2202, etc.), I can refine this further.
