Wiring Diagram
Refer to the following diagram for correct wiring connections. Ensure all power is disconnected before wiring.
Gambar 5: Wiring diagram for the DDS529MR energy meter, including power and RS485 connections.
- Terminal 1 & 2: Live (L) and Neutral (N) input for power supply.
- Terminal 3 & 4: Live (L) and Neutral (N) output for load.
- Terminal 21 & 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.
Instruksi Operasi
Power On
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.
Tampilan Navigasi
The meter features a rotating display of various parameters. Use the NGABUK button to manually cycle through the displayed values:
- Total Energi Aktif (kWh)
- Wektu nyata Voltage (V)
- Real-time Current (A)
- Real-time Active Power (W)
- Faktor Tenaga (PF)
- Frekuensi (Hz)
The display will automatically rotate through these parameters at regular intervals. Pressing the NGABUK button allows for manual advancement to the next parameter.
Komunikasi RS485
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.
Ing SET 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.
Pangopènan
- Reresik: Gunakna kain alus lan garing kanggo ngresiki njaba meter. Aja nggunakake pembersih utawa pelarut sing abrasif.
- Pemriksaan: Periodically inspect the wiring connections for tightness and signs of wear or damage.
- Lingkungan: Priksa manawa lingkungan operasi tetep ana ing kisaran suhu lan kelembapan sing ditemtokake supaya umur meter luwih dawa.
- Ora ana bagean sing bisa dilayani pangguna: The meter contains no user-serviceable parts. Do not attempt to open or repair the device.
Ngatasi masalah
| Masalah | Kemungkinan Penyebab | Solusi |
|---|---|---|
| Tampilan kosong | 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. |
| Wacan sing salah | 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. |
| Gagal komunikasi RS485 | 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. |
