5. Configuration et installation
Proper installation is crucial for the safe and correct operation of the temperature controller. Always ensure power is disconnected before beginning installation.
5.1 Montage
The controller is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals.
5.2 Schéma de câblage
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.
- Type de conducteur : 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. Fonctionnement
Once installed and powered, the controller will display the current temperature. Use the front panel buttons to configure and operate the device.
6.1 Mise sous/hors tension
Appuyez sur le Bouton d'alimentation (usually marked with a circle and vertical line) to turn the unit on or off.
6.2 Setting Temperature and Parameters
Appuyez sur le Bouton de réglage 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.
Common parameters include:
- Set Point (SP): La température souhaitée.
- Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
- Étalonnage de la sonde : Adjusting the sensor reading if necessary.
- Seuils d'alarme : Setting high or low temperature alarm limits.
6.3 Gestion des alarmes
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 Bouton muet to silence the audible alarm. Address the underlying cause of the alarm condition.
7. Entretien
Regular maintenance ensures the longevity and optimal performance of your Rittal temperature controller.
- Nettoyage: Nettoyez régulièrement le panneau avant avec un chiffon doux et sec. N’utilisez pas de nettoyants abrasifs ni de solvants.
- Vérification de la connexion : Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
- Inspection du capteur : Check the NTC temperature sensor and its cable for any physical damage. Ensure it is properly positioned to measure the desired temperature.
- Logiciel/Firmware : There are no user-upgradable software components.
8. Dépannage
If you encounter issues with your temperature controller, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Le contrôleur ne s'allume pas. | No power supply; incorrect wiring; internal fuse blown. | Check power connections (L, N). Verify power source. Consult a technician for internal issues. |
| Lecture de température incorrecte. | 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. |
| L'alarme sonore retentit fréquemment. | 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 Conseils aux utilisateurs
- 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.
