1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of the BEMKO BM A30-BM01B-L Single-Phase Energy Meter. Please read this manual thoroughly before attempting any installation or operation to ensure proper functionality and safety.
The BEMKO BM A30-BM01B-L is a compact, single-phase electronic energy meter designed for measuring active electrical energy consumption in residential, commercial, or industrial applications. It is specifically engineered for mounting on a standard 35mm DIN rail.
2. Safety Information
Warning: Electrical installation and maintenance should only be performed by qualified personnel in accordance with all national and local electrical codes and regulations. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always disconnect power to the circuit before installing, servicing, or removing the energy meter.
- Do not operate the device if it appears damaged or if any part is broken.
- Ensure proper grounding connections are made where required.
- The device is rated IP20, meaning it is protected against solid objects larger than 12.5mm but has no protection against water or moisture. Do not expose the meter to liquids.
- Observe the specified operating temperature range of -10 °C to +45 °C.
3. Product Overview
The BEMKO BM A30-BM01B-L energy meter is designed for accurate and reliable energy measurement. Key features include:
- Rated Voltage: 230V AC
- Rated Current: 10(80)A (Base current 10A, Maximum current 80A)
- Frequency: 50/60Hz
- Accuracy Class: 1.0 (CI.1)
- Pulse Constant: 1000 imp/kWh
- Display: LCD with 5+1 digits for energy readings
- Mounting: 35mm DIN rail (1 module width)
- Power Consumption: < 0.4W / 8VA
4. Setup and Installation
Before installation, ensure that the main power supply is switched off at the circuit breaker to prevent electrical hazards.
4.1 Mounting
- Locate a suitable position within your electrical panel for DIN rail mounting.
- Clip the BEMKO BM A30-BM01B-L meter onto a standard 35mm DIN rail. Ensure it is securely fastened.
4.2 Wiring Connections
Refer to the wiring diagram typically provided on the meter itself or in supplementary documentation. The meter has input and output terminals for the live and neutral conductors.
- Connect the incoming live (L) and neutral (N) wires to the designated input terminals.
- Connect the outgoing live (L) and neutral (N) wires to the designated output terminals, leading to the load circuit.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
After all connections are made and verified, restore power to the circuit. The meter's LCD display should illuminate, indicating it is operational.
5. Operating Instructions
5.1 Reading the Display
The LCD display shows the total accumulated active energy consumption in kilowatt-hours (kWh). The display typically has 5 digits for whole kWh and 1 decimal digit (e.g., 12345.6 kWh).
5.2 Pulse Indicator
The meter features a pulse indicator (often an LED) that flashes at a rate proportional to the energy being consumed. For this model, 1000 flashes correspond to 1 kWh of energy consumption.
5.3 Reset Function
The orange 'RESET' button on the front panel is used to clear the accumulated energy reading. Press and hold the button for a few seconds until the display resets to zero. This function is useful for monitoring energy consumption over specific periods (e.g., daily, weekly, monthly).
6. Maintenance
The BEMKO BM A30-BM01B-L energy meter is designed for maintenance-free operation under normal conditions.
- Cleaning: If cleaning is necessary, gently wipe the exterior with a dry, soft cloth. Do not use abrasive cleaners, solvents, or liquids, as these can damage the device or compromise its IP rating.
- Regular Checks: Periodically inspect the wiring connections to ensure they remain tight and free from corrosion. Check for any visible signs of damage to the meter casing.
7. Troubleshooting
If you encounter issues with your energy meter, consider the following troubleshooting steps:
- No Display/No Power:
- Check if the main power supply to the circuit is active.
- Verify that all wiring connections are correct and secure.
- Ensure the meter is properly seated on the DIN rail.
- Incorrect Readings:
- Confirm that the meter is correctly wired according to the input/output designations.
- Ensure the load connected does not exceed the meter's maximum current rating (80A).
- Pulse Indicator Not Flashing:
- Verify that there is an active electrical load connected and drawing power through the meter.
- Check power supply to the meter.
If problems persist after performing these checks, contact a qualified electrician or the manufacturer's support for assistance. Do not attempt to open or repair the meter yourself.
