How to adjust the supplementary light function of a fiber optic amplifier

To adjust the supplementary light function, you typically enter the amplifier's program or set mode, select the light set or offset option, and then teach or fine-tune the switching threshold using the control buttons.

Step-by-Step Adjustment

1. Enter Program or Set Mode Move the mode switch to the PRG or SET position to access the programming menu. This allows you to modify the light set or supplementary light parameters (Banner DF-G, Datalogic S7) . 2. Select the Light Set Function Use the rocker or push buttons to navigate to the light set or supplementary light option. Press the button to confirm selection. The display will typically flash to indicate that the teach mode is active . 3. Adjust the Offset Percentage The light set function often includes an offset percentage, which determines how far above or below the taught condition the switching threshold is set. Use the control buttons to select the desired offset, which is recommended to set before teaching the amplifier . 4. Teach the Amplifier Move the mode switch to ADJ or remain in the set mode. Present a target object representing the furthest detectable condition. Press the rocker or SET button to teach the amplifier. The display will confirm the new switching threshold and offset percentage . 5. Fine-Tune Manually If needed, manually adjust the switching threshold using the + or – buttons. Hold the button for a few seconds to increment or decrement the value. The display will flash to confirm the new setting . 6. Save and Exit After adjustments, save the parameters by pressing the SET button or following the amplifier's menu instructions. Return the mode switch to RUN to lock the settings and resume normal operation .

Additional Tips

• Automatic vs. Manual Sensitivity: Some amplifiers, like the IFM OBF502, allow automatic sensitivity setting for diffuse or through-beam fibers, which can simplify the process .
• EASY TOUCH or Fine Detection: Datalogic S7 offers standard EASY TOUCH for quick setup and Fine Detection for critical conditions, allowing improved precision .
• Check Stability LED: Ensure the stability LED indicates a sufficient safety margin before finalizing the settings .
• Environmental Considerations: Adjust the light set function considering ambient light, object reflectivity, and fiber type to avoid false triggers . By following these steps, you can effectively configure the supplementary light function to optimize detection performance and ensure reliable operation of your fiber optic amplifier.
