1. Proper Use
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 angle measurement determine the distance
between the sensor and the object. These sensors have small working ranges (under 1 m) and recognize
objects with high precision. Some sensors use a high-resolution CMOS line array and DSP signal processing.
The color, shape and texture of the objects to be recognized does not affect the sensors’ measurements. Even
dark objects can be reliably detected against a bright background.
They can be operated with very high speeds or very high resolutions. The measured value can be output as an
analog value. Furthermore, Teach-In, filter functions for adjusting a switching output, and an error output are
available. The measuring range can be selected individually within the working range.
2. Safety Precautions

• This product is not suitable for safety applications.
• Installation, start-up and maintenance of this product has only to be carried out by trained personal.
• Tampering with or modifying the product is not permissible.
• Protect the product against contamination during start-up.

5. Installation Instructions
During use of the sensors, applicable electrical and mechanical regulations, standards and safety precautions
must be adhered to. The sensor has to be protected against mechanical influences.
In case of very glossy surfaces the sensor has to be mounted slightly inclined and has to be mounted on a
plane surface (approx. 5°), to inhibit a direct reflection of the laser beam into the optics.
6. Initial Operation
Please control the proper connection of all conductors.
Impress a supply voltage of 18...30 V DC with ripple of < 10 % (within the indicated voltage range).
7. Function
The sensor uses a high-resolution CMOS line array and DSP technology, virtually eliminating material, color
and brightness related measurement value differences. Alternatively high speed (Speed-Mode) or high
resolution (Resolution-Mode) are adjustable. Integrated analogue output can be configured for voltage
0…10 V or current 4…20 mA. Teach-In, an Error Output and filter functions are available.

Outputs
Analog Output
The analog output is connected to analog earth. The analog output can be configured as a current output or a
voltage output. If you have the choice we recommend the use of the voltage output (reduced current consump-
tion).
The analog output reads out a standard signal of 0...10 V when configured as a current output (see settings).
The analog output reads out a standard signal of 4...20 mA when configured as a voltage output (see settings).

error has occurred (e.g. an interrupted conductor at the current output). The red F LED lights up to indicate that
the error output has been activated.

Optimize the exposure time
The exposure time is adapted automatically by the sensor. In the presetted DCM (Default Capture Mode) the
Sensor has a fixed maximal possible Exposure Time. It can be adjusted manually in addition in case of difficult
applications.
By means of the LCM (Long Capture Mode) the Exposure Time of the sensor can be elongated for dark or
highly glossy objects (e.g. black lack) in order to achieve a more exact measurement.
By means of the SCM (Short Capture Mode) the Exposure Time of the sensor can be reduced for dark or highly
glossy objects (e.g. black lack) in order to achieve a reduction of the drop down of the Measurement Rate.
The shining of the U-LED and the I-LED the current setting is indicated. DCM is preset in delivery status. By
pressing of the Plus respectively Minus key the current setting can be changed.
