8.5 Response Time for Cascaded Light Screens
Response time is an important factor in determining a light screen’s safety distance (minimum distance). For cascaded EZ-
SCREEN systems, that response time is dependent on the number of light screens, the number of beams in the light
screens, and their positions in the cascade. It can be calculated easily, in two ways:
• Based on the worst-case time for the entire cascade (where all light screens in the cascade have the same safety
distance)
• Individually for each light screen in the cascade (safety distance is calculated for each light screen in the cascade)
