Fault Detection - Omron D40A-G9SX-NS Brochure

Fault Detection

When the Non-contact Door Switch Controller detects a fault, the ERR indicator and/or other indicators light up or flash to inform the user about
the fault.
Check and take necessary measures referring to the following table, and then re-supply power to the Non-contact Door Switch Controller.
