4. Sònrachaidhean

5. Setup agus Stàladh

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

5.1 Stàladh

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

5.2 Diagram uèiridh

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.
• Seòrsa stiùiriche: 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. Obrachadh

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

6.1 Cumhachd air / dheth

Brùth an Putan cumhachd (usually marked with a circle and vertical line) to turn the unit on or off.

6.2 A’ suidheachadh teòthachd agus paramadairean

Brùth an Suidhich am putan 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): The desired temperature.
• Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
• Calibration dearbhaidh: Adjusting the sensor reading if necessary.
• Ceumannan Alarm: Setting high or low temperature alarm limits.

6.3 Riaghladh Alarm

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 Putan mute to silence the audible alarm. Address the underlying cause of the alarm condition.

7. Cumail suas

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

• Glanadh: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Sgrùdadh ceangail: Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
• Sgrùdadh sensor: Check the NTC temperature sensor and its cable for any physical damage. Ensure it is properly positioned to measure the desired temperature.
• Bathar-bog/Firmware: There are no user-upgradable software components.

8. A ’dèanamh trioblaid

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

8.1 Molaidhean Cleachdaiche

• 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.
