5. Pengaturan dan Instalasi

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

5.1 Pemasangan

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

5.2 Diagram Pengkabelan

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.
• Jenis Konduktor: 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. Operasi

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

6.1 Daya Hidup/Mati

Tekan tombol Tombol daya (biasanya ditandai dengan lingkaran dan garis vertikal) untuk menghidupkan atau mematikan unit.

6.2 Pengaturan Suhu dan Parameter

Tekan tombol Tombol setel 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.

Parameter umum meliputi:

• Titik Setel (SP): Suhu yang diinginkan.
• Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
• Kalibrasi Probe: Adjusting the sensor reading if necessary.
• Ambang Batas Alarm: Setting high or low temperature alarm limits.

6.3 Manajemen 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 Tombol bisu to silence the audible alarm. Address the underlying cause of the alarm condition.

7. Pemeliharaan

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

• Pembersihan: Bersihkan panel depan secara berkala dengan kain lembut dan kering. Jangan gunakan pembersih abrasif atau pelarut.
• Pemeriksaan Koneksi: Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
• Inspeksi Sensor: Check the NTC temperature sensor and its cable for any physical damage. Ensure it is properly positioned to measure the desired temperature.
• Perangkat Lunak/Firmware: There are no user-upgradable software components.

8. Penyelesaian masalah

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

8.1 Tips Pengguna

• 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.
