6 Additional functions
Alarm
Alarm output: The sensor (WTS26) features a pre-failure notification output (“Alarm” in
connection diagram [see table 3]), which issues a notification 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 alignment. In the good state: LOW (0),
if excessively contaminated HIGH (1).
Health output: The sensor (WTS26) features a pre-failure notification output (“Health”
in 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
causes: Sensors are contaminated, sensors are out of alignment, cable is damaged. In
the good state: HIGH (1), if excessively contaminated or in the event of cable interrup‐
tion LOW (0). The LED indicator flashes in this case.
Test input
Test input: The WTS26 sensors feature a test input (“TI” or “Test” on the connection
diagram [see table 2, table 3 and table 5]), which can be used to switch the sender off
and, therefore, check that the sensor is functioning correctly: If female cable connec‐
tors with LED indicators are used, you have to ensure that the TI is assigned accord‐
ingly.
If an object is detected, activate the test input (see the connection diagram[see table 2,
table 3 and table 5]). The send LED is shut down or no object being detected is simu‐
lated. Refer to table 5 to check the function. If the switching output fails to behave in
accordance with table 5, check the application conditions. See section Fault diagnosis.

7 Commissioning
1 Alignment
WTS26P: 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 [figure 1].
NOTE
For WTS26P: 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, see figure 7 to
figure 10.
Figure 1: Alignment
2 Sensing range
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 mini‐
mum distance (y) between the set sensing range (x) and the background is to be main‐
tained.
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 correspond‐
ing diagram [figure 2, figure 3] (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 [figure 2 1] as follows:
Example: x = 500 mm, y = 25 mm. That is, the background (black, 6%) is suppressed at a
distance of > 25 mm from the sensor.

3 Sensing range setting
WTS26 x-xxxxxx2 xAxx with Teach-Turn adjustment:
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.). Depend‐
ing 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 plac‐
ing the sensing range in the object, e.g. see figure 4. 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, table 4).

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
1 When adjusting the sensing range, the light spot should be focused on an even, uni‐
form surface, e.g. a white sheet of paper.

2 Turn the potentiometer a fraction counterclockwise until the yellow LED indicator no
longer lights up. The sensing range is now located a fraction above the conveyor belt.

3 The conveyor belt should now be put into operation without any objects. If the yellow
LED indicator does not light up during the test run, the sensing range is set correctly.
