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 a
b
out
the fault.
Check and take necessary measures referring to the following ta
b
le, and then re-supply power to the Non-contact Door Switch Controller.
