The LS-500 series can detect any reduction in incident light intensity, for example, due to the accumulation of dirt such as dust, and issue an alarm. Sensing output 2 can be set as self-diagnosis output. When you reach the threshold for sensing output 1, sensing output 2 is set accordingly, allowing you to shift the threshold by a previously set margin. The LS-500’s threshold-tracking function helps maintain stable sensing over the long term and reduces maintenance man-hours. The incident light intensity can be checked and the threshold automatically reset at a user-selected interval to track changes in light intensity due to environmental changes (such as dust, etc.) over extended periods of time. The LS-500’s ability to perform three logic operations (AND, OR, and XOR) on a standalone basis eliminates the need for a dedicated controller, cuts down on wiring, and lowers costs. Eight sets of amplifier settings can be stored in the unit’s built-in memory. The ability to save and load settings reduces workload when changing the setup in a multimodel production environment.
