Light source interference • Is there any external glare affecting device?
• Installation of multiple light curtains should use transmitter/ receiver staggered format Blue/green/red lights are lit simultaneously Over-current • Check load at output end • Check output mode setting Only blue light is lit, and green light is not lit; red light is lit when shielded Power saving setting • Turn off power saving setting Orange light Wiring error, or input voltage exceeds specifications • Check if wire connection is normal • Check if input voltage is within range Abnormal internal signal/ voltage • Contact DELTA service center Red/green lights are lit, and blue lit is not lit Abnormal number of beams • Beam number setting error, or abnormal number of internal beams Contact DELTA service center
