Standard teaching for average sensor sensitivity
 Press teach button until the yellow LED flashes.
 Release teach button.
 Ready.
After the standard teaching, the sensor
switches when half of the light beam is
covered by the object.
Teaching for increased sensor sensitivity
 Press teach button until green and yellow LEDs
flash alternately.
 Release teach button.
 Ready.
After the teaching for increased sensor
sensitivity, the sensor switches when
about 25% of the light beam are covered
by the object.
Teaching for maximum operating range (factory setting at delivery)
 Prior to teaching:
Cover
the light path to the reflector!
 Procedure as for standard teaching.
Adjusting the switching behavior of the switching output – light/dark switching
This function permits inversion of the sensors' switching logic.
 Press teach button until the green LED flashes.
 Release teach button.
 The LED then displays the changed switching logic for
2s:
YELLOW = switching outputs light switching
Continuous light (in the case of complementary sen-
sors, Q1 (pin 4) light switching, Q2
(pin 2) dark switching), this means
output active when object is
detected.
GREEN = switching outputs dark switching
Flashing light (in the case of complementary sen-
sors, Q1 (pin 4) dark switching, Q2
(pin 2) light switching), this means
output inactive when object is
detected.
 Ready.
