• Switch position "N" (standard operation):
• Switch position "T" (Teach-in mode):
• Switch positions "I", "II" and "III" (contrast detection mode)
• Ext. TEACH-IN input
Mounting instructions:
The sensor is held in place by two pass-through drill holes for M5. The surface underneath must be flat to prevent the housing
from moving when it is tightened into position. We recommend securing the nuts in place with spring screws to prevent the sen-
sor from going out of adjustment.
Outdoor mounting:
The sensors must be protected from shock and splashed water. It may be necessary to provide a covering.
Adjustment:
Additional information
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“).
