Tab. 1: Pin assignment
As shipped or after resetting the sensor to factory defaults
Pin 2 and Pin 4 are configured as a PNP switching output
(Q1/Q2). The switching logic for Q1 is normally open, Q2 is
normally closed. The sensor uses the diffuse energetic
sensor principle (see section Factory setting on page 5).

Yellow LED function indicator
LED on: light at the receiver
LED off: no light at the receiver
LED flashing: Uncertain range or error indication (see
page 19)
Green LED power and short-circuit indication
LED on: Power present, SIO mode

LED off: Sensor not ready
Setter (digital potentiometer)
Used for setting the switchpoint and displaying the sensor
principle as well as various other functions.
The settings can also be made using IO-Link
(see section Sensor function principle and Teach-In
procedure on page 6).
The sensitivity of the setter depends on the
turning speed.
Fast turning results in a larger increment size of
the switchpoint.

Display and operating elements (continued)
Multi-color LED (in setter)
LED blue: Diffuse energetic sensor
LED pink: Diffuse sensor with background suppression
LED white: Retro-reflective
LED orange: Through-beam receiver
LED off: Through-beam emitter
Flashing:
–
LED flashes red (synchronous with LED 1 and LED 2):
Lifetime end reached.
–
All LEDs flashing synchronous with turning of the
setter: End of the setting range reached.
–
LED flashing when switchpoint is applied: 3-time
flashing when saving the just set switchpoint.
Settings on the sensor in the sensor principle
Diffuse energetic sensor /
Diffuse sensor with background suppression
Note correct approach direction in this mode!
Standard setting
1. Position the sensor to the desired distance from the
object.
2. Set the setter to the minimum switching distance.
3. Slowly turn the setter clockwise until the yellow LED is
on constantly. The object has been detected.
4. Remove object: the yellow LED goes out.
Fine adjustment
1. Continue turning setter clockwise until the yellow LED
comes on: the background is detected.
2. Set the setter in the middle between both detected
switchpoints.
