Installation Guide

• Mount the transmitter and receiver facing each other across the guarded opening.
• Keep the detecting distance between 0.2 m and 10 m for stable operation.
• Align both units carefully to stay within the ±2.5° effective aperture angle.
• Choose optical or wire synchronization according to your wiring plan.
• Connect the 24 VDC supply and confirm the OSSD outputs switch correctly.
• Separate nearby GL-R systems using the Channel A/B switch for optical mode.
• Verify the ø14 mm detection capability with a test rod before production starts.
