1. Use for Intended Purpose
This wenglor product has to be used according to the following functional principle:
High-performance distance sensor
High-performance distance sensors which use the principle of transit time measurement determine the dis-
tance between the sensor and the object according to the principle of transit time measurement. These sensors
have a large working range and are therefore able to detect objects over large distances.
Selected sensors are distinguished by WinTec (wenglor interference free technology). This technology allows
black or shiny surfaces to be reliably detected even in extremely inclined positions. It is possible to mount sev-
eral sensors next to or across from each other without them influencing each other.
2. Safety Precautions

6. Initial Operation
6.1. Initial Operation
Before the configuration, connect the Sensor to 18…30 V DC.
The desired menu language must be selected after initial start-up, and after each reset (see fig. 1).
Fig. 1: Set menu language
The functions of the keys appear in the display as follows:
5: Navigate up.
6: Navigate down.
: Selection is acknowledged with the enter key.
The keys within a menu item can also be assigned to letters or other symbols such as “+” and “–”. You can
keep the “+” or “–” key pressed for a longer time in order to make larger numerical jumps.

9
Meaning of the menu items:
3Back: one level higher in the menu.
7Run: switch to delay mode.
Switch to the configuration menu by pressing any key.
Note:
If no settings are adjusted in the configuration menu for a period of 30 s, the Sensor is automatically returned to
the read-out view. The Sensor accesses the last used menu view when a key is once again activated.
If a setting is adjusted, it becomes active when the configuration menu is exited.
Important:
Do not use any sharp objects to press the keys when configuring settings, because they might otherwise
be damaged.

7.3.1. Switching Output Foreground Teach-In
Teach-In is performed while the sensor spot is aligned to the object. The switching distance is then automati-
cally set to a distance which is slightly greater than the clearance between the sensor and the object. The sen-
sor is thus activated for all objects whose distance to the sensor is equal to or less than the distance to the
object used for the Teach-In procedure.

if needed.
• The switching hysteresis can be modified in the menu item Hysteresis (see chap-
ter 7.3.5) if needed.
7.3.2. Switching Output Background Teach-In
Teach-In is performed while the sensor spot is aligned to the background. The switching distance is then au-
tomatically set to a distance which is slightly less than the clearance between the sensor and the background.
The sensor is thus activated whenever an object is located between the background and the sensor.

• The center of the window can be readjusted in the menu item Poti (see chapter
7.3.4) if needed. The two switching points are alternately displayed in this process.
• The switching hysteresis can be modified in the menu item Hysteresis (see chap-
ter 7.3.5) if needed.
Examples of applications:
Ex. 1: Recognition of objects that are very difficult to recognize visually, e.g., shiny black metal plates in an
extremely slanted position in front of a background.
–> Use Teach-In Background for this application.
Ex. 2: Distinction of objects, e.g., small and large packages on a conveyor belt.
–> In this application, use Teach In to the object to be recognized, at which the Sensor is to switch.

7.6. Expert Menu
Different menu items and sub-items appear in the menu, depending on whether the Expert Menu is “On” or
“Off”. The Expert Menu is off in the delivery state. The menu is thereby shorter and easier to use. If the existing
menu items are not sufficient for the application solution, the Expert Menu can be switched on in order to use
the full scope of Sensor functions.

7.7. Filter
The filter (filter size) is the number of measurement values over which the Sensor takes an average. The larger
the selected filter, the slower the response time of the Sensor becomes when there is change of the measure-
ment values. A larger filter improves the reproducibility of the Sensor.
Note: The menu item is only visible if Expert Menu “On” has been set.

If 1 is selected, each measurement value is output directly without averaging.
Whenever a value greater than 1 is selected, the Sensor takes an average over
the selected number of x measurement values, which is output every 2 ms at the
output.
