Determine the safety distance, mount the emitter and receiver at the correct position and angle, verify power voltage, and perform alignment checks before powering on.
Connect the device to a DC 12‑24 V supply, use the appropriate NPN or PNP output, keep power consumption under 10 W, and follow the wiring diagrams for I/O and safety relay connections.
Inspect and tighten all screws, clean the housing with soft water‑soaked cloth, replace broken filters, and conduct six‑month checks of wiring and functionality.
Check the power supply, verify correct wiring, ensure proper alignment, confirm the device is within its protection range, and examine output fault indicators for possible wiring or internal faults.
