4. Prodotto finitoview e componenti

The Walfront Timer Relay Module is a compact circuit board designed for precise timing applications. Familiarize yourself with its key components:

Figura 4.1: Sopraview of the Walfront Timer Relay Module with key components labeled. This image shows the relay, power indicator, switch indicator, and the two adjustment potentiometers.

• Relè: The blue rectangular component responsible for switching the load on and off. It has NO (Normally Open), COM (Common), and NC (Normally Closed) terminals.
• Indicatore di alimentazione (LED verde): Illuminates when the module is powered on.
• Switch Indicator (Red LED): Illuminates when the relay is activated (switched on).
• "On" Time Adjustment Potentiometer: Used to set the duration for which the relay remains ON.
• "Off" Time Adjustment Potentiometer: Used to set the duration for which the relay remains OFF (in cycle mode).
• Mode Jumper (Mon./Cycle): A small jumper pin that allows selection between single (Mon.) and continuous cycle (Cycle) modes.
• Input Terminals (+, -): For connecting the DC power supply to the module.
• Key Input Terminal: For connecting an external start/stop button.

5. Configurazione e installazione

Before proceeding with installation, ensure the power supply is disconnected. Refer to the wiring diagrams below for correct connections.

5.1. Wiring Diagram 1: Separate Power Supplies for Module and Load

This configuration is used when the module and the load are powered by different power sources, or when the load requires an AC power supply.

Figura 5.1: Wiring diagram showing separate power supplies for the module (BT1) and the load. The module's power input is connected to BT1, and the load's power is connected through the relay's COM and NO terminals.

1. Connect the module's power input (labeled '+' and '-') to your DC power supply (BT1), ensuring correct polarity.
2. Connect the load's power supply (Power 2) to one side of the load.
3. Connect the other side of the load to the NO (normalmente aperto) terminal of the relay.
4. Collegare il COM (Comune) terminal of the relay to the other side of the load's power supply (Power 2).
5. Optionally, connect an external start/stop button (S1 Key) to the 'Key' input terminals.

Important: Do not reverse the positive and negative of the power supply. If you need to power on and cycle immediately without an external button, short the start button wire directly.

5.2. Wiring Diagram 2: Shared Power Supply for Module and Load

This configuration is used when the module and the load share the same DC power source.

Figura 5.2: Wiring diagram showing a shared power supply for both the module and the load. The module's power input and the load's power are derived from the same source, with the load connected through the relay's COM and NO terminals.

1. Connect the module's power input (labeled '+' and '-') to your DC power supply, ensuring correct polarity.
2. Connect the positive (+) terminal of the power supply to one side of the load.
3. Connect the other side of the load to the NO (normalmente aperto) terminal of the relay.
4. Collegare il COM (Comune) terminal of the relay to the negative (-) terminal of the power supply.
5. Optionally, connect an external start/stop button (S1 Key) to the 'Key' input terminals.

Important: Ensure the shared power supply can handle the current draw of both the module and the load without exceeding its capacity.

6. Istruzioni per l'uso

6.1. Mode Selection (Mon./Cycle)

The module supports two operating modes: Single (Mon.) and Continuous Cycle (Cycle). Select the desired mode using the jumper pin on the board.

Figura 6.1: Avvicinamento view of the mode selection jumper. The jumper can be placed in either the 'Mon.' position for single operation or 'Cycle' for continuous cycling.

• Mon. (Single Mode): In this mode, the relay will activate for the set "On" time once triggered, then remain off until triggered again.
• Cycle (Continuous Cycle Mode): In this mode, after being triggered, the relay will continuously cycle between the set "On" time and "Off" time until stopped.

6.2. Regolazione dell'ora

Use the two potentiometers on the board to adjust the "On" and "Off" times. These are typically blue square components with a screw slot for adjustment.

Figura 6.2: The two potentiometers for adjusting the 'On' and 'Off' durations. Rotate them clockwise to increase time and counter-clockwise to decrease time.

• "On" Time Potentiometer: Adjusts the duration the relay is active (load is ON).
• "Off" Time Potentiometer: Adjusts the duration the relay is inactive (load is OFF). This is primarily used in Cycle mode.

The timing range depends on the specific model variant (e.g., 0-30 minutes, 0-24 hours). Refer to the specifications for your module's exact range.

6.3. Avvio e arresto del funzionamento

• Using an External Button: If an external start/stop button is connected to the 'Key' terminals, press it once to start the timing cycle. Press it again to stop the cycle.
• Avvio automatico: If no external button is connected and you wish for the module to start immediately upon power-up, short the 'Key' input terminals. This will simulate a button press.

7. Manutenzione

The Walfront Timer Relay Module is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• Mantenere pulito: Periodically inspect the module for dust or debris accumulation. Use a soft, dry brush or compressed air to gently clean the circuit board. Do not use liquids or solvents.
• Controllo ambientale: Ensure the operating environment remains within specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive heat, or moisture.
• Integrità della connessione: Occasionally check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Evitare lo stress fisico: Do not bend, drop, or apply excessive force to the module. Handle with care to prevent damage to components or solder joints.
