5. Configuración e instalación
Proper installation is crucial for the safe and correct operation of the temperature controller. Always ensure power is disconnected before beginning installation.
5.1 Montaxe
The controller is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals.
5.2 Diagrama de cableado
Refer to the diagram on the back of the unit (Figure 2) for precise wiring connections. Use the provided removable terminal blocks for secure connections.
- Power Input (L, N): Connect the main 230V~ power supply to terminals L and N.
- Control Outputs (1, 2, 3): These are relay contacts for controlling external devices (e.g., compressor, fan). Connect your load circuits to these terminals as per your system design.
- NTC Probes (4, 5, 6): Connect the NTC temperature sensor(s) to these terminals. Ensure correct polarity if specified by the sensor. The image shows three terminals for probes, suggesting support for multiple sensors or a specific configuration.
- Tipo de condutor: Always use copper conductors for all electrical connections.
Warning: Incorrect wiring can cause damage to the device, electrical shock, or fire. Consult a qualified electrician if unsure.
6. Funcionamento
Once installed and powered, the controller will display the current temperature. Use the front panel buttons to configure and operate the device.
6.1 Encendido/apagado
Preme o Botón de acendido (normalmente marcado cun círculo e unha liña vertical) para acender ou apagar a unidade.
6.2 Setting Temperature and Parameters
Preme o Botón Establecer to enter the parameter setting mode. The display will typically show a parameter code or the current set point. Use the arrow buttons (if present, or repeated presses of Set/Mute in some models) to navigate through parameters and adjust values. Press Set again to confirm changes and exit programming mode.
Os parámetros comúns inclúen:
- Punto de axuste (SP): A temperatura desexada.
- Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
- Calibración da sonda: Adjusting the sensor reading if necessary.
- Limiares de alarma: Setting high or low temperature alarm limits.
6.3 Xestión de alarmas
If an alarm condition occurs (e.g., temperature outside set limits), the controller may trigger an audible alarm and display an error code. Press the Botón de silencio to silence the audible alarm. Address the underlying cause of the alarm condition.
7. Mantemento
Regular maintenance ensures the longevity and optimal performance of your Rittal temperature controller.
- Limpeza: Limpa periodicamente o panel frontal cun pano suave e seco. Non empregues produtos de limpeza abrasivos nin disolventes.
- Comprobación de conexión: Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
- Inspección do sensor: Check the NTC temperature sensor and its cable for any physical damage. Ensure it is properly positioned to measure the desired temperature.
- Software/Firmware: There are no user-upgradable software components.
8 Solución de problemas
If you encounter issues with your temperature controller, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| O controlador non se acende. | No power supply; incorrect wiring; internal fuse blown. | Check power connections (L, N). Verify power source. Consult a technician for internal issues. |
| Lectura de temperatura incorrecta. | Faulty NTC sensor; sensor incorrectly placed; wiring issue. | Check sensor connections (4, 5, 6). Ensure sensor is in the correct measurement area. Replace sensor if damaged. |
| Control output (e.g., cooling) not activating. | Set point not reached; differential setting too wide; faulty relay; incorrect wiring. | Verify set point and differential settings. Check wiring to control outputs (1, 2, 3). Test external device. |
| Audible alarm sounds frequently. | Temperature consistently outside alarm thresholds; alarm thresholds set too narrow. | Check system operation to ensure temperature is stable. Adjust alarm thresholds if necessary. |
8.1 Consellos para o usuario
- For critical applications, consider installing a secondary temperature monitoring system.
- Keep a record of your parameter settings for quick restoration after power outages or resets.
- Ensure the NTC sensor is placed in a location representative of the cabinet's internal temperature, away from direct airflow from cooling units or heat sources.
