Installation instructions
When installing the light curtain, ensure a safe distance between the light curtain and the hazardous area of the machine. Failure to stop the machine before reaching its hazardous area may result in severe injury or death.
Calculate the safe distance correctly and maintain the minimum safe distance between the detection zone and the hazardous parts of the machine.
Safe distance refers to the minimum distance between the detection plane of the light curtain and the cutting edge or hazardous parts of the machine.
