(Thru-beam type EX-33□, Diffuse reflective type EX-32□)
Thru-beam type EX-33□
● When using EX-33□, turn the sensitivity adjuster fully clockwise to the MAX. position.
However, if the beam penetrates a sensing object, adjust the sensitivity as follows.
Step
1. Turn the sensitivity adjuster fully counterclockwise to the
minimum sensitivity position.
2. In the light received condition, turn the sensitivity adjust-
er slowly clockwise and confirm the point A where the
sensor enters the "Light" state operation.
3. In the dark condition, turn the sensitivity adjuster further
clockwise until the sensor enters the "Light" state opera-
tion and then bring it back to confirm point B where the
sensor just returns to the "Dark" state operation.
4. The position at the middle of points A and B is the opti-
mum sensing position.
Note: Use the flathead screwdriver (purchase separately) to turn the adjuster slowly. Turning with excessive
strength will cause damage to the adjuster.
