Installation Considerations

AG4 Safety Laser Scanner

At a minimum, a risk assessment must address: Unmonitored Areas

– Behind and to the sides of the scanner– "Shadowing" within the Protective Field– Needle-shaped and cone-shaped contours

Adjacent Scanners– Could add 40 ms to

response time

Application Examples

AG4 Application Overview

Two-Hand Control

Diverse redundant and self-checking

– Dual microcontrollers

– Multiple optical paths The patented diverse-redundant,

self-checking design will detect an internal safety-critical circuit fault and immediately switch its outputs to the OFF state.
