Installation Guide
Mount the transmitter and receiver facing each other. Use the metal housing for robust fixing. Keep the distance between 0.3 m and 15 m. Align the units for optical synchronization. The effective angular aperture is ±2.5°. Connect the 24 VDC power supply. Ensure the ripple is 10% or less. Use a Class 2 power source. Wire the PNP outputs to your safety circuit. The response time is fast at 4.3 ms. This helps stop the machine quickly.
Debugging and Maintenance
Check the indicator LEDs for status. The transmitter draws max. 62 mA. The receiver draws max. 74 mA. Use the switch setting for interference prevention. You can connect up to 2 units in series. Clean the front cover with a soft cloth. Do not use abrasive cleaners. The protection rating is IP65/IP67. This allows use in dusty or wet areas. The operating temperature range is wide. It works from -30 to +55 °C.
Compatibility Notes
This light curtain uses PNP output. It works with most safety relays and controllers. The optical synchronization means no extra wires for sync. No built-in communication ports are available. No expansion is possible. It is a standalone safety device. The GL-V series offers other models. Check your machine voltage before connection.
