1. Introduzione
This manual provides essential instructions for the safe and effective use of the Keyence FS-V31 Fiber Optic Sensor. The FS-V31 is a digital, single-control fiber optic sensor designed for industrial applications, featuring NPN output and selectable Light-ON/Dark-ON operation. It operates on a 12-24 VDC input and has a low power consumption of 0.71 WATT.
Si prega di leggere attentamente il presente manuale prima dell'installazione, dell'uso o della manutenzione per garantire il corretto funzionamento e prevenire potenziali pericoli.
2. Informazioni sulla sicurezza
Observe the following safety precautions to prevent injury to personnel and damage to the equipment.
- Sicurezza elettrica: Ensure the power supply is disconnected before wiring or performing any maintenance. Incorrect wiring can lead to electric shock or equipment damage.
- Alimentazione elettrica: Use only a 12-24 VDC power supply as specified. Exceeding this voltage range can damage the sensor.
- Ambiente: Do not install the sensor in locations subject to excessive vibration, shock, high temperatures, corrosive gases, or direct sunlight.
- Cablaggio: Tutti i cablaggi devono essere eseguiti da personale qualificato in conformità con le normative elettriche locali.
- Modifiche: Do not attempt to disassemble, repair, or modify the sensor. Unauthorized modifications can lead to malfunction and void the warranty.

4. Configurazione e installazione
4.1 Montaggio
Mount the FS-V31 sensor securely in a location free from excessive vibration and heat. Ensure adequate space for wiring and access to control buttons. Use appropriate mounting hardware (not included) for your specific application.
4.2 Cablaggio
Refer to Figure 3.2 for wiring color codes. Connect the sensor to a stable 12-24 VDC power supply according to the following:
- BROWN Wire: Connect to +V (Positive DC Power Supply)
- BLUE Wire: Connect to 0V (Negative DC Power Supply / Ground)
- BLACK Wire: NPN Output (Connect to load, then to +V)
Assicurarsi che tutti i collegamenti siano sicuri e isolati per evitare cortocircuiti.
5. Funzionamento
5.1 Accensione
Once wired correctly, apply 12-24 VDC power. The sensor will power on, and indicator lights will illuminate to show its status.
5.2 Light-ON / Dark-ON Selection
The FS-V31 allows selection between Light-ON and Dark-ON modes. In Light-ON mode, the output activates when light is detected. In Dark-ON mode, the output activates when light is interrupted (darkness is detected).
Refer to Figure 3.3 for control button locations. Use the 'MODE' or 'SEL' button to cycle through operating modes. Consult the sensor's display (if present) or indicator lights to confirm the selected mode.
5.3 Regolazione della sensibilità
The 'SET' and 'DSC' buttons (refer to Figure 3.3) are typically used for sensitivity adjustment or teaching functions. Follow these general steps:
- Place the target object in the desired detection position.
- Press and hold the 'SET' button (or follow specific sequence) to initiate teaching.
- Remove the target object (if applicable for 2-point teaching).
- Press the 'SET' button again to complete the teaching process.
The sensor will automatically adjust its threshold for optimal detection based on the taught conditions.
6. Manutenzione
The Keyence FS-V31 is designed for minimal maintenance. However, regular inspection and cleaning can prolong its lifespan and ensure reliable operation.
- Pulizia: Periodically clean the sensor's detection surface and housing with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Ispezione dei cavi: Check the integrated cable for any signs of damage, such as cuts, abrasions, or kinks. Replace the sensor if the cable is damaged.
- Sicurezza del montaggio: Verify that the sensor remains securely mounted and that all connections are tight.
7. Risoluzione Dei Problemi
If the sensor is not operating as expected, refer to the following common issues and solutions:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Sensor does not power on. | No power supply, incorrect wiring, or faulty power supply. | Check power connections (BROWN to +V, BLUE to 0V). Verify power supply voltage (12-24 VCC). |
| Output does not switch. | Incorrect Light-ON/Dark-ON mode, improper sensitivity adjustment, or target out of range. | Verify selected operating mode. Re-adjust sensitivity using 'SET' button. Ensure target is within detection range. |
| Erratic detection. | Dust/dirt on sensor lens, external light interference, or unstable mounting. | Clean sensor lens. Shield sensor from strong ambient light. Securely mount the sensor. |
