4. Configurare
4.1 Montare
The XMTD-3002 controller is designed for flush mounting. Ensure adequate space for ventilation and access to wiring terminals. Secure the controller using the provided mounting brackets.
Figura 3: Latura view illustrating the mounting bracket mechanism and a general wiring diagram. The diagram shows connections for both thermocouples and RTDs (thermal resistors).
4.2 Cablare
All wiring should be performed by a qualified electrician in accordance with local electrical codes. Ensure the power supply is disconnected before making any connections.
- Identify the power input terminals (AC 220V).
- Connect the CU50 RTD sensor to the designated input terminals. For CU50 (RTD), typically a three-wire connection is used for compensation. Refer to the wiring diagram on the unit or in Figure 4.
- Connect the control output terminals to your heating or cooling element as required.
- Asigurați-vă că toate bornele cu șurub sunt strânse bine pentru a preveni conexiunile slăbite.

5. Instrucțiuni de utilizare
5.1 Pornire/Oprire
- To power on the device, ensure all wiring is correct and then connect the main power supply. The 'ON' indicator light will illuminate, and the display will show the current measured temperature.
- To power off, disconnect the main power supply.
5.2 Setting the Temperature (Set Point)
The XMTD-3002 features a simplified operation process for setting the desired temperature.
- Apăsați tasta SET button once. The display will typically show the current set point, often indicated by a small light next to '设定值' (Set Value).
- Utilizați Up (↑) şi Down (↓) arrow buttons to adjust the set point to your desired temperature.
- Apăsați tasta SET button again to confirm and save the new set point. The display will return to showing the measured temperature.
5.3 Parameter Adjustment (Advanced Settings)
For advanced parameters such as proportional band, integral time, derivative time, alarm settings, or sensor calibration, a longer press of the SET button (e.g., 3-5 seconds) may be required to enter the parameter setting mode. Consult the specific parameter codes and adjustment procedures provided with your unit, as these can vary.
6. Întreținere
- curatenie: Keep the controller's front panel clean and free from dust. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspecţie: Periodically check wiring connections for tightness and signs of corrosion or damage.
- Mediu: Ensure the operating environment is within the specified temperature and humidity ranges to prolong the life of the device.
7. Depanare
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Fără afișaj/Fără alimentare | No power supply; Loose wiring; Blown fuse (internal/external) | Check power connection; Verify wiring; Check fuse. |
| Citirea incorectă a temperaturii | Sensor wiring error; Damaged sensor; Incorrect sensor type selected (if configurable) | Verify sensor wiring (CU50); Replace sensor; Check parameter settings. |
| Controller not heating/cooling | Output wiring error; Damaged heating/cooling element; Set point not reached; Control mode issue | Check output wiring; Test heating/cooling element; Adjust set point; Review control parameters. |
| Afișajul arată „HHHH” sau „LLLL” | Sensor open circuit (HHHH) or short circuit (LLLL); Temperature out of range | Check sensor and wiring; Replace sensor if damaged. |
