Installation Guide

• Mount the sensor on a stable bracket and tighten the mounting hole to 0.5 N·m maximum.
• Keep the sensing face clean and free of dust, oil, and water droplets.
• Align the sensor toward the target and confirm the green stable LED lights up.
• Turn the 230° trimmer to set sensitivity for your specific target and background.
• Select LIGHT-ON or DARK-ON mode according to your control logic.
• Wire the 2 m cable to a 10 to 30 VDC supply and observe polarity.
• Space units apart or use the different frequency function to avoid interference.
• Avoid direct sunlight above 20,000 lux and strong incandescent light above 5,000 lux.
