Two zones can be widely monitored with Panasonic SD3-A1, the warning zone (within a radius 15 m 49.213 ft) and the detection zone (protection zone) (within a radius 4 m 13.123 ft). The contours of these zones are fully configurable for a perfect fit in every application. Up to eight zone patterns can be set and switched over at any given time, even during operation. By activating the reference boundary function which enables constant detection of stationary objects, the safety laser scanner memorizes the position of stationary objects, and monitors for beam misalignment after installation. The response time is adjustable within the range from 80 to 640 ms. When setting up multiple safety laser scanners in close vicinity, mutual interference can be prevented by adjusting the response time. Configurations can be saved in the optional configuration plug which has a built-in memory. Even after maintenance or interchanging of safety laser scanners, the configurations from the memory in the plug can be easily loaded and recovered without the need to configure through a PC.
