• Switch position "N" (normal operation):
Yellow LEDs light if the light beam is free, flash if the functional reserve is used, turn off if the light beam is interrupted.
• Switch position "T" (TEACH-IN operation):
Yellow LED flashes slowly after 1 second (about 1.5 Hz).
The sensor is now ready to be set to a particular contrast detection value using the mechanical switch (position I, II, or III) or an exter-
nal signal.
• Switch positions "I", "II", and "III" (contrast detection operation)
Contrast detection values: I for 10 %, II for 18 %, III for 40 %.
1. Yellow LED lights continually: light path free
2. Yellow LED off: object detected
3. Yellow LED flashes quickly: unsure detection, too much contamination, functional reserve too low.
A direct switching of the contrast detection levels is possible without having to put the switch back into position "T" first.
• External teach input (ET):
In switch position "T", you can apply a pulse over a control line to plug pin 5 to select the corresponding contrast detection.
The desired contrast detection is set by applying a high pulse of a particular width:
I: 50 ms (30 ms ... 100 ms)
II: 150 ms (100 ms ... 200 ms)
III: >200 ms
• Pre-fault output (optional):
Switch position "N":
Inactive if the functional reserve is used after approx. 5 sec. Immediately inactive if 4 light beam interruptions occur within the flashing time.
Contrast detection levels:
The output goes inactive if the contamination no longer permits readjustment; the yellow LED flashes quickly. In the case of additional contamination, the detection
of low contrast is no longer guaranteed.
• Warm-up period:
Any warm-up period can be shortened by repeating the learn (teach) process.
