4. Specificazioni

5. Setup è Installazione

Proper installation is crucial for the safe and correct operation of the temperature controller. Always ensure power is disconnected before beginning installation.

5.1 Muntamentu

The controller is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals.

5.2 Schema di cablaggio

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.
• Tipu di cunduttore: 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. Operazione

Once installed and powered, the controller will display the current temperature. Use the front panel buttons to configure and operate the device.

6.1 Power On/Off

Press u Pulsante di putenza (di solitu marcatu cù un cerchju è una linea verticale) per accende o spegne l'unità.

6.2 Impostazione di a temperatura è di i parametri

Press u Set buttone 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:

• Puntu di impostazione (SP): A temperatura desiderata.
• Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
• Calibration de la sonde : Adjusting the sensor reading if necessary.
• Soglie di alarme: Setting high or low temperature alarm limits.

6.3 Gestione d'alarme

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 buttone Mute to silence the audible alarm. Address the underlying cause of the alarm condition.

7. Mantenimentu

Regular maintenance ensures the longevity and optimal performance of your Rittal temperature controller.

• Pulizia: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Verificazione di a cunnessione: Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
• Ispezione di sensori: 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. Risoluzione di prublemi

If you encounter issues with your temperature controller, refer to the following common problems and solutions:

8.1 Cunsiglii per l'utilizatori

• 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.
