5. セットアップとインストール
Proper installation is crucial for the safe and correct operation of the temperature controller. Always ensure power is disconnected before beginning installation.
5.1 取り付け
The controller is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals.
5.2 配線図
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.
- 電源入力（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.
- 導体タイプ: 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. 操作
Once installed and powered, the controller will display the current temperature. Use the front panel buttons to configure and operate the device.
6.1 電源オン/オフ
を押す 電源ボタン (usually marked with a circle and vertical line) to turn the unit on or off.
6.2 温度とパラメータの設定
を押す 設定ボタン 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.
一般的なパラメータは次のとおりです。
- Set Point (SP): 希望する温度。
- Differential/Hysteresis (dIF): The temperature difference before the output changes state again.
- プローブの校正: Adjusting the sensor reading if necessary.
- アラームしきい値: Setting high or low temperature alarm limits.
6.3アラーム管理
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 ミュートボタン to silence the audible alarm. Address the underlying cause of the alarm condition.
7. メンテナンス
Regular maintenance ensures the longevity and optimal performance of your Rittal temperature controller.
- クリーニング： 定期的に、柔らかく乾いた布でフロントパネルを拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。
- 接続チェック: Annually inspect all wiring connections for tightness and signs of corrosion. Ensure terminal blocks are securely seated.
- センサー検査: Check the NTC temperature sensor and its cable for any physical damage. Ensure it is properly positioned to measure the desired temperature.
- ソフトウェア/ファームウェア： There are no user-upgradable software components.
8。 トラブルシューティング
温度コントローラーで問題が発生した場合は、次の一般的な問題と解決策を参照してください。
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| コントローラの電源が入らない。 | No power supply; incorrect wiring; internal fuse blown. | Check power connections (L, N). Verify power source. Consult a technician for internal issues. |
| 温度の読み取りが正しくありません。 | 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. |
| 警報音が頻繁に鳴ります。 | 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 ユーザーのヒント
- 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.
