What is the self-diagnostic function?
The self-diagnostic function checks for errors in Safety Sensors.
Self-diagnosis occurs when the power is turned ON (within 1 s) and periodically during operation.
This function is called self testing for F3SN/F3SH Series Safety Light Curtains.
Applicable models:
F3SL Series Safety Light Curtain
F3SS-AT60P Single-beam Safety Sensor
