6. Persediaan dan Pemasangan
The Baomain DM25S is designed for easy installation on a standard 35mm DIN rail. Ensure power is disconnected before proceeding.
6.1. Pemasangan
- Locate a suitable 35mm DIN rail within your distribution panel or control cabinet.
- Align the meter's DIN rail clip with the rail.
- Press the meter firmly onto the DIN rail until it clicks into place, ensuring it is securely fastened.
6.2. Sambungan Pendawaian
Refer to the wiring diagram below for correct connections. This meter is a single-phase, 2-wire device.
Figure 4: Wiring Diagram for Baomain DM25S Energy Meter.
- Terminal 1 (L): Connect the incoming Phase (Live) line.
- Terminal 3 (L): Connect the outgoing Phase (Live) line to the load.
- Terminal 4 (N): Connect the incoming Neutral line.
- Terminal 6 (N): Connect the outgoing Neutral line to the load.
- Terminals 20 & 21 (SO): These are for the pulse output contact. Connect external monitoring equipment here if pulse output is required.
After all connections are made, double-check for proper polarity and secure terminals before restoring power.
7. Arahan Operasi
7.1. Hidupkan kuasa
Once the meter is correctly installed and wired, restore power to the circuit. The meter will automatically begin measuring energy consumption.
7.2. Display Reading
The meter features a 5+1 digit mechanical counter display, showing total energy consumption in kilowatt-hours (kWh). The last digit (after the decimal point) represents tenths of a kWh.
7.3. Petunjuk LED
- Green LED (Power Supply Indicator): Illuminates when the meter is connected to power and operating correctly.
- Red LED (Consumption Indicator): Flashes to indicate active energy consumption. The flash rate is 2000 impulses per kWh (0.5Wh/imp). A faster flash rate indicates higher power consumption.
8. Penyelenggaraan
The Baomain DM25S energy meter is designed for long-term, maintenance-free operation. However, periodic checks are recommended:
- Pembersihan: Pastikan meter bersih dan bebas daripada habuk. Gunakan kain lembut dan kering untuk membersihkan. Jangan gunakan pembersih atau pelarut yang kasar.
- Semakan Sambungan: Periksa sambungan pendawaian secara berkala untuk memastikan ia kekal ketat dan kukuh.
- Keadaan Persekitaran: Pastikan persekitaran operasi kekal dalam julat suhu dan kelembapan yang ditetapkan.
- Tiada Bahagian Boleh Servis Pengguna: Do not attempt to open or repair the meter. Refer all servicing to qualified personnel.
9. Penyelesaian masalah
If you encounter issues with your Baomain DM25S energy meter, refer to the following common troubleshooting steps:
- Meter Not Powering On (Green LED Off):
- Periksa sama ada kuasa dibekalkan ke litar.
- Verify all wiring connections (Terminals 1, 4) are correct and secure.
- Pastikan input voltage is within the operational range (100-300V AC).
- Red LED Not Flashing (No Consumption Indication):
- Ensure there is an active load connected to the meter (Terminals 3, 6).
- Verify the load is drawing current (operational current range 0.25A ~ 40A).
- Check wiring to the load for continuity.
- Bacaan Tidak Tepat:
- Confirm correct wiring according to the diagram (Figure 4). Incorrect wiring can lead to inaccurate measurements.
- Ensure the meter is not exposed to strong magnetic fields or extreme environmental conditions.
If the problem persists after performing these checks, contact customer support for further assistance.
