5 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor’s maximum permissible tightening torque of 2 Nm.
Note the preferred direction of the object relative to the sensor, cf. see "Dimensional
drawing", page 15.
6 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Plug connection: note pin assignment: when the cover is open, the male connector
can be swiveled horizontally and vertically.
– Terminal connection: note the permissible cable diameter of 5 to 10 mm. When
the cover is open, the M16 fitting can be swiveled horizontally and vertically.
Unscrew the M16 fitting and remove sealing plug. Lead voltage-free supply cable
through and connect sensor in accordance with table 2 and table 4. Retighten
M16 fitting with seal so that the IP enclosure rating of the device is ensured.
Figure 1: Opening the sensor Figure 2: Electrical connection
Only apply voltage/switch on the power supply once all electrical connections have
been established.

7 Additional functions
Alarm
Alarm output: the sensor (WT34-Vxxx) features a pre-failure notification output (“Alarm”
in connection diagram [see "WT34-Bxxx, WT34-Vxxx", page 7]), which issues a notifica‐
tion if the sensor is only ready for operation to a limited extent. The LED indicator
flashes in this case. Possible causes: sensor is contaminated, sensor is out of align‐
ment. In the good state: LOW (0), if excessively contaminated HIGH (1).

ADDITIONAL FUNCTIONS 7
8009202.11O1 | SICK
Subject to change without notice 9

Test input
Test input: the WT34-B / -V sensors feature a test input (“TI” or “Test” on the connec‐
tion diagram [see "WT34-Bxxx, WT34-Vxxx", page 7 and see table 7]), which can be
used to switch the sender off and, therefore, check that the sensor is functioning cor‐
rectly: if female cable connectors with LED indicators are used, you have to ensure that
the TI is assigned accordingly.
If an object is detected, activate the test input (see the connection diagram [see
"WT34-Bxxx, WT34-Vxxx", page 7 and see table 7], PNP: TE → M). The send LED is shut
down or no object being detected is simulated. Use the following table to check the
function. If the switching output fails to behave in accordance with the following table,
check the application conditions. See section Fault diagnosis.

1Alignment
WT34-Xx4x, -Xx5x: 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 sensor is completely clear [see figure 3 and figure 4].
WT34-Xx1x, -Xx2x: align sensor on object. Select the position so that the infrared light (not
visible) hits the center of the object. The correct alignment can only be detected via the
LED indicators. See figure 3 and figure 4. You must ensure that the optical opening (front
screen) of the sensor is completely clear.

7 ADDITIONAL FUNCTIONS
10 8009202.11O1 | SICK
Subject to change without notice

WT34 are photoelectric proximity sensors with background suppression. Depending on the
remission of the object to be detected, and perhaps the background behind it, a minimum
distance (y) between the set sensing range (x) and the background should be maintained.
Remission: 6% = black 1, 18% = gray 2, 90% = white 3 (referring to standard white as
per DIN 5033). We recommend that the adjustment be performed with an object of low
remission.
The minimum distance (= y) for the background suppression can be determined from the
diagram [figure 5 1] as follows:
Example: x = 600 mm, y = 4.5 => 4.5% of 600 mm = 27 mm. That is, the background is
suppressed at a distance of > 627 mm from the sensor.

3Sensing range setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the device.
The sensing range is adjusted with the potentiometer (type: without stop ). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced. We rec‐
ommend placing the object within the sensing range, e.g. see table 8. 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 figure 5 and
figure 6].

Table 9: 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
Object in beam path, no output
signal
Test input (Test) is not con‐
nected properly
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output signal
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check operating conditions:
align light beam (light stop)
completely on the object /
cleaning of optical surfaces /
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
Increase the sensing range
11 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).
NOTE
Disposal of batteries, electric and electronic devices
•According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
•The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
This symbol on the product, its package or in this document, indicates
that a product is subject to these regulations.
12 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•Clean the external lens surfaces
•Check the screw connections and plug-in connections

18 Montage
Den Sensor an einen geeigneten Befestigungswinkel montieren (siehe SICK-Zubehör-
Programm).
Maximal zulässiges Anzugsdrehmoment des Sensors von 2 Nm beachten.
Vorzugsrichtung des Objektes zum Sensor beachten, vgl. siehe "Maßzeichnung",
Seite 29.
19 Elektrische Installation
Anschluss der Sensoren muss spannungsfrei erfolgen. Je nach Anschlussart sind die
folgenden Informationen zu beachten:
– Steckeranschluss: Pinbelegung beachten: wenn der Deckel geöffnet ist, kann der
Stecker nach horizontal und vertikal geschwenkt werden
– Klemmenanschluss: Zulässigen Leitungsdurchmesser von 5 bis 10 mm beachten.
Wenn der Deckel geöffnet ist, kann die M16-Verschraubung nach horizontal und
vertikal geschwenkt werden. M16-Verschraubung lösen und Dichtungsstopfen ent‐
fernen. Spannungsfreie Versorgungsleitung durchführen und Sensor nach
Tabelle 12 und Tabelle 14 anschließen. M16-Verschraubung mit Dichtung wieder
anziehen, damit die IP-Schutzart des Gerätes sichergestellt wird.
Abbildung 9: Öffnen des Sensors Abbildung 10: Elektrischer Anschluss
Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung anlegen
bzw. einschalten.
