Installation Guide

• Mount the transmitter and receiver facing each other at the planned guard opening.
• Keep the effective aperture angle within ±2.5° when the operating distance reaches 3 m or more.
• Choose optical or wire synchronization before wiring, because the wiring method sets the mode.
• Use the Channel A/B switch for optical synchronization when two GL-R systems operate nearby.
• Connect the 24 VDC Class 2 supply and confirm the indicator turns ON before testing.
• Verify that the OSSD turns ON only when no interruption exists in the detection zone.
• Test the ø14 mm detection capability with a test rod across the full 460 mm detection height.
