6 Electrical installation
The sensors must be connected in a voltage-free state (UV = 0 V). The following informa‐
tion must be observed depending on the connection type:
– Plug connection: pin assignment
– Cable: wire color
Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐
tions have been established.
Explanation of connection terminology:
BN = Brown
WH = White
BU = Blue
BK = Black
n. c. = no connection
Q = switching output 1
Q = switching output 2
L+ = supply voltage (Uv)
M = common
L.ON = light operate
D.ON = dark operate

7 Commissioning
7.1 Alignment
Align sensor on object. Select the position so that the red emitted light beam hits the
center of the object. You must ensure that the optical opening (front screen) of the sen‐
sor is completely clear [see figure 0].
7.2 Sensing range
Adjust the mounting position so that the sensing range and background are within
specification. Refer to see figure 2, page 9.
NOTE
Please note the minimum range of 5 mm.

Use see table 2, page 7 to check the function. If the switching output fails to behave in
accordance with see table 2, page 7, check the application conditions.

7.3 Settings
Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensing range is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:
sensing range increased; counterclockwise rotation: sensing range reduced. We recom‐
mend placing the object within the sensing range, e.g. see figure 2. Once the sensing
range has been adjusted, the object is removed from the path of the beam, which
causes the background to be suppressed and the switching output to change [see
table 2].
Table 3: Adjustment sensing range

Subject to change without notice 9

The sensor is adjusted and ready for operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 4: Troubleshooting
LED indicator/fault pattern Cause Measures
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
object / Clean the optical sur‐
faces / Check sensing range
and adjust if necessary
Yellow LED lights up, no object
in the path of the beam
The sensing range distance is
too large
Reduce the sensing range
Object is in the path of the
beam, yellow LED does not
light up
Distance between the sensor
and the object is too long or
sensing range is set too short
Reduce the sensing range
9 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).

18.1 Angleichung
Sensor am Objekt ausrichten. Die Position so wählen, dass der rote Sendelichtstrahl
die Mitte des Objekts trifft. Es muss sichergestellt werden, dass die Optiköffnung
(Frontscheibe) des Sensors komplett frei ist [siehe Abbildung 0].
18.2 Schaltabstand
Die Montageposition so anpassen, dass der Schaltabstand und der Hintergrund inner‐
halb der Spezifikationen liegen. Siehe "Abbildung X".
