CONTRAST SENSORS

Concept of operation

Teach-in dynamic

Press the teach-in button and

keep it pressed. LED flashing

slowly.

1. Position background

Keep the teach-in button

> 3 < 30 s pressed.

2. Move at least the mark

and background using

the light spot.

Release the teach-in button.

Yellow LED will illuminate, when

emitted light is on the mark.

Switching characteristics

The optimum emitted light is selected automatically (at RGB variants).

Static teach-in: light/dark setting is defined using teach-in sequence.

Dynamic teach-in: switching output active on mark, if background is longer in the field of view during the teach-in.

The switching threshold is set in the center between the background and the mark.

If the button is pressed again within 10 s of the teach (> 20 ms < 10 s), the relative switching threshold

is placed 75 % between mark (100 %) and background (0 %) (dotted line in Figure).

Teach-in can also be performed using an external control signal.

Keylock activation and deactivation: hold down teach-in button > 30 s.

Teach-in failure: yellow LED indicator and the transmitted light of the sensor flashing quickly.
