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.
For dynamic teach-in with ET signal (5 Hz) via switching output Q.
