5. Instruccions de funcionament

5.1 Power-Up and Display

Once correctly installed and powered, the meter's 5+1 digital display will show the accumulated energy consumption in Kilowatt-hours (KWh). The display format is 99999.1 KWh.

5.2 Indicadors LED

• POWER (Green LED): Illuminates when the meter is receiving power, indicating normal operation.
• PULSE (Red LED): Flashes to indicate energy consumption. Each flash represents a specific amount of energy (e.g., 1600 imp/KWh), as specified on the meter's faceplate. A faster flash rate indicates higher power consumption.

5.3 Sortida d'impulsos

The meter provides a standard passive (non-polar) pulse output, allowing it to interface with various AMR systems for remote energy monitoring. Refer to IEC 62053-31 and DIN43864 standards for pulse output specifications.

6. Manteniment

The Walfront DDM75S energy meter is designed for long-term, maintenance-free operation. However, periodic checks are recommended:

• Neteja: Gently wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Integritat de la connexió: Periodically inspect wiring connections to ensure they remain secure. Loose connections can lead to inaccurate readings or operational issues.
• Condicions ambientals: Assegureu-vos que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats per evitar danys.

7. Solució De Problemes

• Meter not displaying: Check power supply and wiring connections. Ensure the green POWER LED is illuminated.
• El LED de pols no parpelleja: Verify that there is an active load connected and consuming power. If the load is active but the LED is not flashing, check wiring or contact support.
• Lectures inexactes: Ensure all connections are tight and correct according to the wiring diagram. Verify the meter's specifications match the electrical system.

If issues persist, consult a qualified electrician or contact Walfront customer support.
