Logarex LK13BE904xxx Energy Meter Guide

This document provides a comprehensive guide to the Logarex LK13BE904xxx three-phase energy meter, detailing its specifications, operation, display, communication, and error handling.

Core Principles

• Measures active electrical energy in 3-phase, 4-wire networks with high accuracy (Class A).
• Features an LCD display with OBIS identifiers for detailed energy data and status.
• Supports both optical (PUSH) and RS485 (PULL) communication interfaces for data output.
• Conforms to European MID 2014/32/EU directive and relevant EN standards.
• Offers configurable PIN protection and service modes for advanced functionality and data access.
• Designed for precise energy measurement and robust data communication in modern electrical grids.

Action Steps

• Access the menu by a short press of the mechanical or optical button on the rolling display.
• Enter PIN by short presses for digit selection and waiting 3 seconds to confirm each digit.
• Toggle "Inf" (Information) setting between "on" (full data) and "OFF" (reduced data) using a long press to control optical interface output.
• Activate/deactivate PIN protection by long-pressing the button when "Pin on" or "Pin OFF" is displayed.
• Connect the meter via RS485 to a Logarex BAB-Adapter for communication with a Smart Meter Gateway or LMN-Auslesesoftware.

Key Terms

• LK13BE904XXX: Specific model designation for the Logarex three-phase energy meter.
• OBIS-CODE: Object Identification System code, used to identify specific data points on the meter's display.
• MID 2004/EEC: Measurement Instruments Directive, European regulation for measuring instruments.
• RS485: A standard for serial communication, used for bidirectional data exchange with the meter.

Pro Tips

• The "Inf" setting directly impacts the completeness of data transmitted via the optical interface.
• Service mode displays energy with higher precision (3 decimal places) and only for the active tariff.
• PIN settings are retained even after power interruptions, requiring re-entry if active.

Pitfalls to Avoid

• Incorrect PIN entry will return the display to the rolling view, requiring re-entry.
• Attempting to activate/deactivate calibration mode simultaneously with other commands is not possible.
• Ignoring EEPROM or checksum error indications (FF(010000), FF(100000)) can lead to incorrect readings or malfunction.

People

• Electrical Engineer: Designs and implements electrical systems, including energy metering.
• Meter Technician: Installs, maintains, and troubleshoots energy meters.
• Regulatory Body Representative: Ensures compliance with measurement standards like MID 2014/32/EU.
