This application uses a Photoelectric Sensor with light-intensity switching.
The E3Z Sensor with Light-intensity Switching achieves preventive maintenance by periodically performing a sensor test.
Conventional self-diagnosis functions could not inspect operating margins of light intensity because the sensor stopped emitting.
If the Sensor fails to operate when the incident level is switched to 1/2 by a signal sent by a PLC, you can determine that the operating margin is too small and maintenance is required. Thus you will maintain the system.
