Note the sensor’s maximum permissible tightening torque of < 1.3 Nm.
5 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Note pin assignment
– Cable: wire color
Only supply/switch on the voltage once all electrical connections have been estab‐
lished.

6 Additional functions
Alarm
Alarm output: The sensor (WTS26) features a pre-failure notification output (“Alarm”
in the connection diagram [see table 3]), which issues a notification if the sensor is
only ready for operation to a limited extent. The LED flashes in this case. Possible
causes: sensor is contaminated, sensor is out of alignment. In the good state: LOW (0),
if excessively contaminated HIGH (1).
Health
Health output: The sensor (WTS26) features a pre-failure notification output (“Health”
in the connection diagram [see table 3]), which issues a notification if the sensor is
only ready for operation to a limited extent or the cable has been interrupted. Possible
ADDITIONAL FUNCTIONS 6

causes: Sensor is contaminated, sensor is out of alignment, cable is damaged. In the
good state: HIGH (1), if excessively contaminated or in the event of cable interruption
LOW (0). The yellow LED indicator flashes in this case.
Test input
Test input: The sensors WTS26 feature a test input (“TI” or “Test” on the connection
diagram [see table 2]), which can be used to switch the sender off and, therefore,
check that the sensor is functioning correctly: 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
table 2]).
The send LED is shut down or no object being detected is simulated. Refer to table 5
to check the function. If the switching output fails to behave in accordance with the
graphic, check the application conditions, see "Troubleshooting", page 15.

7 Commissioning
7.1 Alignment
WTS26P: Align the sensor with the 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 2].
NOTE
For WTS26: If the objects are detected from above, we recommend installing the sen‐
sor at an angle in order to prevent total reflection by a reflective surface, see figure 7.

7.2 Check the application conditions
WTS26 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 is to be
maintained.
Check the application conditions: Adjust the sensing range and distance to the object
or background as well as the remission capability of the object according to the corre‐
sponding diagram [see table 6] (x = sensing range, y = minimum distance between set
sensing range and background (white 90%)). 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 [table 6 1] as follows:
Example: x = 500 mm, y = 25 mm. That is, the background (white, 90%) is suppressed
at a distance of > 25 mm of the configured sensing range.

7.3 Sensing range setting
WTS26x-xxxxxx2xAxx with Teach-Turn adjustment:
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.).
Depending on the requirements, the potentiometer can be used for fine-tuning (without
pressing the teach-in button).
Clockwise rotation: Sensing range increased.
Counterclockwise rotation: Sensing range reduced.
The sensing range can also be adjusted using just the potentiometer. We recommend
placing the sensing range in the object, e.g. see figure 4, page 11. 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 (table 4).

Detection of flat, glossy, contrast-rich, and uneven objects.
If the objects are detected from above, we recommend installing the sensor at an angle
in order to prevent total reflection by a reflective surface

uniform surface, e.g. a white sheet of paper.

no longer lights up. The sensing range is now located a fraction above the con‐
