Product Information

Full details

The Finder 7M.38.8.400.0312 is a professional-grade, 3-phase digital energy meter designed for accurate monitoring of electricity consumption in industrial and commercial settings. Its key benefit is precise bidirectional measurement with dual-tariff functionality, allowing for efficient energy management and cost optimization. A potential caveat is its 3-phase focus, though it can be used in single-phase applications up to 80A. Key features include an 80A capacity, 230/400V AC compatibility, MID certification, an LCD display, and multiple communication interfaces like M-Bus and SO.

Extended Product Information

FAQs

Can this meter be used for single-phase applications?

Yes, the Finder 7M.38.8.400.0312 can be used in single-phase applications with a current rating up to 80A, although it is designed with 3-phase systems in mind.

What does MID certification mean for this meter?

MID (Measuring Instruments Directive) certification means the meter has been tested and approved according to European standards for accuracy and reliability, making it suitable for use in applications where energy consumption needs to be billed accurately.

How do I reset the partial consumption reading?

The partial consumption (resettable kWh, kVAh, kvar) can be reset using a specific button or sequence as indicated in the meter's user manual. Consult the detailed manual for the exact procedure.

What is the pulse rate for the SO interface?

The SO interface outputs 500 pulses per kWh.

What is the maximum conductor size supported?

For the main circuit, the meter supports single-wire conductors from 1.5 to 16 mm² and multi-wire conductors from 1.5 to 25 mm².

Does the LCD display have a backlight?

Yes, the Dot Matrix LCD display is backlit for improved visibility in various lighting conditions.

What is the warranty period for this energy meter?

Please refer to the official Finder warranty documentation for specific details regarding the warranty period applicable to this product model.

Troubleshooting

Display is blank / Meter not powering on

Verify that the main circuit is energized and that the voltage is within the nominal range (230/400V AC). Check all wiring connections to ensure they are secure and correctly installed according to the diagram.

Inaccurate readings

Ensure the meter is correctly wired for the system type (3-phase/single-phase) and that current direction is properly accounted for if applicable. Check that the ambient temperature is within the operating range. If issues persist, contact technical support.

M-Bus or SO communication not working

Confirm that the communication cables are correctly connected to both the meter and the receiving device. Verify that the correct communication parameters (e.g., baud rate for M-Bus) are set on both ends. Check the documentation for the connected system.

Error message on LCD display

Refer to the meter's specific technical manual for a list of error codes and their meanings. Common solutions may involve power cycling the device or checking for specific environmental conditions.

Pros and Cons

Pros

  • Highly accurate bidirectional energy measurement.
  • Dual-tariff support for optimized energy costs.
  • MID certification ensures compliance and reliable billing.
  • Versatile communication options (M-Bus, SO).
  • Robust 80A capacity suitable for demanding loads.
  • Clear, backlit LCD display with comprehensive data.

Cons

  • Primarily designed for 3-phase systems, requiring specific wiring.
  • M-Bus and SO interface configuration may require technical expertise.
  • Installation requires DIN rail mounting, not suitable for all enclosures.
  • Short-term overcurrent rating (2400A for 10ms) is specific and needs consideration for fault scenarios.

Setup, Compatibility & Care

Setup:

  1. Mounting: Install the meter on a standard 35mm DIN rail (EN 60715) within a suitable enclosure. Ensure adequate ventilation.
  2. Wiring: Connect the main circuit conductors according to the 3-phase or single-phase configuration, observing the specified conductor cross-sections (Single-wire: 1.5 to 16 mm²; Multi-wire: 1.5 to 25 mm²).
  3. Communication: Connect M-Bus or SO interface cables to your respective monitoring or automation system.
  4. Power Up: Energize the circuit to activate the meter and its LCD display.

Compatibility:

  • Voltage: Compatible with 3 x 230/400V AC nominal voltage systems.
  • Current: Supports up to 80A continuous current.
  • System Type: Suitable for 3-wire and 4-wire systems.
  • Communication Protocols: M-Bus (300-9600 baud) and SO interface protocols.

Care:

  • Cleaning: Disconnect power before cleaning. Wipe the exterior with a dry or slightly damp, soft cloth. Avoid harsh chemicals or abrasive materials.
  • Environment: Operate within the ambient temperature range of -25 to +70°C. Ensure the enclosure provides adequate protection against dust and moisture (IP50 for housing, IP20 for connections).
  • Sealing: The terminal cover is designed for sealing, maintaining the integrity of the electrical connections.
