5. Installazione (configurazione)

The Circutor CEM-C30-312 MID is designed for DIN rail mounting. Ensure all safety precautions are followed before beginning installation.

5.1 Montaggio

1. Ensure the power supply to the installation is completely disconnected.
2. Mount the meter onto a standard DIN rail (35mm) in an electrical panel.
3. Ensure adequate ventilation around the meter to prevent overheating.

5.2 Collegamenti di cablaggio

The CEM-C30-312 MID uses indirect measurement, requiring external current transformers (CTs). Refer to the wiring diagram provided with your current transformers and the meter for precise connections. Below is a general guide:

• Voltage Connessioni: Collegare il volumetage inputs (L1, L2, L3, N) to the corresponding phases and neutral of the electrical system.
• Current Transformer Connections: Connect the secondary outputs of the current transformers (e.g., S1, S2) for each phase to the meter's current input terminals. Ensure correct polarity.
• Uscita impulsiva: If using the pulse output, connect it to the desired external device (e.g., PLC, BMS) according to DIN 43864.
• Porta ottica: The lateral optical port is for connecting the optional CEM-M communication module.

Important: Incorrect wiring can lead to inaccurate readings or damage to the meter. Always double-check all connections before restoring power.

6. Funzionamento

Once installed and powered, the CEM-C30-312 MID will begin measuring electrical energy. The meter's operation is primarily managed through its LCD display and two control buttons.

6.1 Display e navigazione

The 7-digit LCD display shows various electrical parameters in a rotating sequence. Use the control buttons to manually cycle through the available screens or access specific functions.

• Button 1 (Unsealable): Typically used for navigating through display screens and confirming selections.
• Button 2 (Sealable): Often used for resetting partial counters or accessing advanced settings. This button is typically sealed after commissioning to prevent unauthorized resets.

Commonly displayed parameters include:

• Total Active Energy (kWh)
• Partial Active Energy (kWh)
• Total Reactive Energy (kvarh)
• Vol. istantaneotage (V) per phase
• Instantaneous Current (A) per phase
• Instantaneous Active Power (kW) per phase and total
• Fattore di potenza (PF)
• Frequenza (Hz)

6.2 Resetting Partial Counter

To reset the partial energy counter, press and hold the designated (sealable) button for a few seconds until the display confirms the reset. This function is typically protected to prevent accidental data loss.

7. Specifiche tecniche

8. Manutenzione

The Circutor CEM-C30-312 MID energy meter is designed for long-term, maintenance-free operation. However, periodic checks can help ensure its continued performance.

• Pulizia: Gently wipe the exterior of the meter with a soft, dry cloth. Do not use abrasive cleaners, solvents, or liquids that could enter the device.
• Ispezione visiva: Periodically inspect the meter for any signs of physical damage, loose connections, or discoloration.
• Nessuna parte riparabile dall'utente: The meter contains no user-serviceable parts. Do not attempt to open or repair the device, as this will void the warranty and may pose a safety risk.

9. Risoluzione Dei Problemi

If you encounter issues with your CEM-C30-312 MID meter, refer to the following common problems and solutions:

• Nessuna visualizzazione:
  • Controllare se l'alimentazione del contatore è attiva.
  • Verifica tutti i volumitage connections are secure and correct.
• Incorrect Readings / "Mal Conexionado" (Incorrect Connection) Message:
  • Ensure current transformer (CT) connections are correct, paying attention to polarity.
  • Verifica volumetage connections are correctly matched to phases.
  • Confirm the CT ratio settings (if applicable and configurable) match your installed CTs.
• Pulsanti che non rispondono:
  • Assicurarsi che il misuratore sia acceso.
  • If a button is sealed, it may be intentionally disabled for certain functions.

If the problem persists after attempting these solutions, please contact Circutor technical support.
