セットアップとインストール
取り付け
The DDS529MR energy meter is designed for standard 35mm DIN rail installation. Ensure the DIN rail is securely mounted in a suitable enclosure or panel.
- Align the meter's DIN rail clip with the DIN rail.
- カチッと音がするまでメーターをレールにしっかりと押し付けます。
- Verify the meter is securely fastened and does not wobble.
図4: 後方 view showing the DIN rail mounting mechanism.
配線図
Refer to the following diagram for correct wiring connections. Ensure all power is disconnected before wiring.
図5: Wiring diagram for the DDS529MR energy meter, including power and RS485 connections.
- ターミナル1と2: Live (L) and Neutral (N) input for power supply.
- ターミナル3と4: Live (L) and Neutral (N) output for load.
- ターミナル21と20: Pulse output (SO+ and SO-).
- Terminals A & B (RS485): Data communication lines for RS485 (MODBUS-RTU).
Connect the main power supply to the input terminals (L and N). Connect the load to the output terminals (L and N). For RS485 communication, connect the A and B terminals to your RS485 network.
操作手順
電源オン
Once correctly wired and mounted, switch on the main power supply. The LCD display will illuminate, and the power indicator LED (G in Figure 1) will light up.
ナビゲーションを表示
The meter features a rotating display of various parameters. Use the 順番 button to manually cycle through the displayed values:
- 総有効エネルギー（kWh）
- リアルタイムVoltage（V）
- Real-time Current (A)
- Real-time Active Power (W)
- 力率（PF）
- 周波数 (Hz)
The display will automatically rotate through these parameters at regular intervals. Pressing the 順番 button allows for manual advancement to the next parameter.
RS485通信
The DDS529MR supports RS485 communication using the MODBUS-RTU protocol. This allows for remote reading of energy data and other parameters. Refer to the MODBUS protocol documentation for detailed register addresses and communication settings.
の セット button (K in Figure 1) is typically used for configuring communication parameters such as baud rate and address, or for resetting certain values. Consult the full technical datasheet for specific programming instructions if available.
メンテナンス
- クリーニング： メーターの外装を清掃する際は、柔らかく乾いた布をご使用ください。研磨剤入りの洗剤や溶剤は使用しないでください。
- 検査： Periodically inspect the wiring connections for tightness and signs of wear or damage.
- 環境： メーターの寿命を延ばすには、動作環境が指定された温度と湿度の範囲内に保たれていることを確認してください。
- ユーザーが修理可能な部品はありません: The meter contains no user-serviceable parts. Do not attempt to open or repair the device.
トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| 表示が空白 | No power supply; incorrect wiring; internal fault. | Check power connections and ensure power is on. Verify wiring according to the diagram. If problem persists, contact support. |
| 誤った測定値 | Incorrect wiring; meter not calibrated; external interference. | Double-check all wiring. Ensure the meter is installed correctly for single-phase measurement. If readings are consistently off, contact support. |
| RS485 通信障害 | Incorrect wiring of A/B lines; wrong baud rate/address; software configuration issue. | Verify RS485 wiring. Check baud rate, parity, and address settings on both the meter and the communication device. Consult MODBUS protocol documentation. |
| Pulse indicator not flashing | No load connected; very low power consumption; internal fault. | Ensure a load is connected and drawing power. The pulse rate is 1000 imp/kWh, so for very low loads, flashes may be infrequent. |
