• Synchronization: Optical or wire synchronization, determined by wiring
• Detection mode: Output turns ON when no interruption exists in the detection zone

Installation Guide

• Mount the transmitter and receiver face to face so all 87 beam axes align across the guarded opening.
• Keep the effective aperture angle within ±2.5° when the operating distance reaches 3 m or more.
• Choose optical synchronization for simple layouts, or wire synchronization for fixed cabinet wiring.
• Set the Channel A/B switch when two GL-R systems operate near each other.
• Feed a stable 24 VDC Class 2 supply and keep ripple at 10% or less for consistent OSSD switching.
• Wire the two OSSD outputs to the safety relay or controller and confirm the 13.8 ms response budget.
• Verify the ø14 mm detection capability with a test rod after alignment and before production starts.
