Description

EIN

green

on , if power supply is applied

MAX

red

on , if distance goes above Max level (*)

OK

green

on , if distance is inbetween Min-level and Max-level (*). F1 and F2 are not activated.

MIN

yellow

on , if distance is below Min level (*)

F2

red

on , if surface is reflecting too much light

F1

yellow

on , if surface is reflecting too little light (f.i. when the object is too far, or if the reflecting surface or the lenses are dirty.

(*) Min and Max level are user-adjustable
