• Electronic automatic overload and over-temperature protection.
• Function and time settings are entered via two buttons (MODE and SET) and displayed numerically on an integrated LCD screen.

4. Configurazione e installazione

The Eltako MFZ12PMD-UC is designed for series installation within an electrical distribution board. Due to the inherent risks associated with electrical installations, it is mandatory that installation is carried out by a qualified electrician in accordance with all local and national electrical codes and regulations.

4.1. Schema elettrico

Refer to the detailed wiring diagram printed on the side of the device and consult the comprehensive electrical schematics provided with the product packaging for precise connection instructions.

• Connect the main power supply (L-N 230V~) to the designated terminals.
• Connect the electrical load (e.g., lamps) to the X1 and X2 terminals.
• Connect control inputs (+A1, -A2, +E1, -E2, +F1) for universal control voltage (8-230V UC) as required by the chosen function and your specific application.
• Ensure all terminal connections are secure and properly tightened to prevent loose contacts.

The display shows 'ARV' and '9.0S', indicating function and time settings. The device also has 'MODE' and 'SET' buttons visible below the display.

5. Istruzioni per l'uso

The MFZ12PMD-UC offers 18 distinct functions, which are selected and configured using the MODE and SET buttons in conjunction with the integrated LCD screen.

5.1. Selezione della funzione

1. Premere il tasto MODALITÀ button repeatedly to cycle through the 18 available functions. Each function will be indicated on the LCD display.
2. Once the desired function is displayed, press the IMPOSTATO pulsante per confermare la selezione.

5.2. Impostazione dell'ora

1. After selecting a function that requires a time setting (e.g., delay ON, delay OFF), use the IMPOSTATO button to adjust the time value. The LCD will show the current time setting, typically in seconds (S).
2. Continua a premere IMPOSTATO to increment the time, or hold it down for faster adjustment.
3. Refer to the specific function descriptions in the complete product documentation for detailed timing parameters and ranges.

5.3. Dimming Functions

For functions involving dimming, the minimum and maximum brightness levels can be adjusted. If the minimum brightness is not set to 0, the connected lamp will dim to the set percentage rather than switching off completely. This feature allows for customized lighting control.

6. Manutenzione

The Eltako MFZ12PMD-UC is designed to be a maintenance-free device under normal operating conditions. To ensure optimal performance and longevity, adhere to the following guidelines:

• Ensure the operating environment is clean, dry, and within the specified temperature and humidity ranges.
• Periodically, a qualified electrician should check terminal connections for tightness to prevent potential issues from loose wiring.
• Do not expose the device to excessive moisture, corrosive substances, or extreme temperatures.
• Cleaning should only be performed with a dry, soft cloth. Do not use liquid cleaners, solvents, or abrasive materials.

7. Risoluzione Dei Problemi

If the device is not functioning as expected, consider the following troubleshooting steps:

• Nessun potere: Verify that the main power supply to the device is active and all connections to terminals N and L are secure.
• Load Not Responding: Check that the connected load (e.g., lamp) is functional and correctly wired to terminals X1/X2. Ensure the selected function is appropriate for the load type.
• Tempistica/Funzione errata: Re-check the function selection and time settings using the MODE and SET buttons. Refer to the full product manual for specific function details and their corresponding settings.
• Overload/Overheating: The device features electronic protection. If it has shut down, reduce the connected load or ensure adequate ventilation around the device. Allow the unit to cool down before attempting operation again.
• Problemi di oscuramento: Confirm that the connected lamps are explicitly rated as dimmable. Review the minimum and maximum brightness settings.

IMPORTANTE: For any persistent issues, complex electrical problems, or if you are unsure about any step, consult a qualified electrician. Do not attempt unauthorized repairs or modifications to the device.
