LEDs are lit when the light beam is unobstructed, they flash when the value falls short of the function reserve and they go
out when the beam is interrupted.
After 1 s, the LED flashes slowly (approx. 1.5 Hz). The sensor is now ready to be set for a specific contrast detection value
either via the mechanical switch (pos. I, II or III) or an external signal.
Contrast recognition values: I for 10 %, II for 18 %, III for 40 %
1. LED permanently lit: light path unobstructed
2. LED off: element to be sensed detected
3. LED flashes rapidly: detection failure, excessive soiling, function reserve too low.
The desired contrast recognition capability can be adjusted by applying of a logic „high“ pulse with a certain pulse lenght when the switch is in position T.

It is possible to change the contrast detection level without re-teaching. For contras detection mode (Teach-Mode) the stability reseve must be at least 2.5
(see curve „relative received light strength“).
