How to set the power of the fiber optic sensor
The power of a fiber optic sensor is set by selecting the appropriate power mode and calibrating the light intensity using the sensor's buttons or amplifier settings.
Steps to Set Power
- Access Power Mode
- Press and hold the MODE button for about 3 seconds to enter advanced settings or power mode selection on most industrial fiber optic sensors (e.g., Keyence FS-N series) .
- The display will indicate the current mode, such as FINE, TURBO, or SUPER.
- Select the Appropriate Power Mode
- FINE: For detecting small differences at short distances.
- TURBO: For longer detection distances when FINE mode is insufficient.
- SUPER: For harsh environments with dust, debris, or variable conditions .
- Use the manual button to scroll through and select the desired mode, then press MODE to confirm .
- Calibrate Light Intensity
- Place the target object at the farthest detection point and press the SET key to record the minimum light intensity.
- Move the object closer to the sensor until the desired maximum intensity is reached and press SET again.
- The sensor will automatically calculate the trigger threshold and display it as a percentage of light intensity (e.g., 15% threshold) .
- Adjust Sensitivity (Optional)
- Some sensors allow fine-tuning of sensitivity using △ and ▽ buttons or the amplifier interface.
- This ensures reliable detection even if environmental conditions change .
- Confirm and Save Settings
- After selecting the power mode and calibrating, press MODE or SET as instructed to save the configuration.
- Some sensors allow locking the settings to prevent accidental changes .
- Output Signal Configuration
- Choose between LIGHT-ON or DARK-ON output modes depending on whether the sensor should trigger when light is detected or blocked .
Tips
- Always ensure the sensor is clean and free from dust or debris before calibration.
- For reflective sensors, align the optical axis carefully to maximize received light intensity.
- If the environment is highly variable, consider using SUPER mode to maintain stable detection. By following these steps, you can effectively set the power and sensitivity of a fiber optic sensor to match your application requirements, ensuring accurate and reliable detection.
