1. Proper Use
This wenglor product is used in accordance with the following mode of operation:
Both plastic fiber optic cables and glass fiber optic cables can be connected to fiber optic cable sensors.
Universal reflex sensors can be used both with and without fiber optic cables. Fiber optic cable sensors ana-
lyze the light reflected by the object. The output switches when an object reaches the selected range (detec-
tion) or when the active light beam is interrupted (operating limits). Bright objects reflect more light than dark
objects, and can thus be recognized from greater distances. In barrier operation, the color of the object has
no effect on the range.
2. Safety Precautions
• This operating instruction is part of the product and must be kept during its entire service life.
• Read this operating instruction carefully before using the product.
• 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.
• Not a safety component in accordance with the EU Machinery Directive
3. General Information Regarding the Device
wenglor fiber optic cables can be adapted to these Sensors. The modern OLED display assures easy, menu-
driven Sensor setup. Signal strengths and the switching threshold can be read from the display as numeric
values or as a bar graph. Convenient programming and quick diagnosis is possible via the IO-Link interface.

5. Initial Operation
Connect the Sensor to 18 to 30 V DC before configuring the settings.
The desired menu language must be selected after initial operation, and after each reset.
See section 6.7 in this regard.
Switch to the configuration menu by pressing any key.
Note: If no settings are adjusted in the configuration menu for a period of 30 seconds, the Sensor is auto-
matically returned to the display mode.
The Sensor accesses the last used menu view when a key is once again activated. If a setting is configured,
it becomes active when the configuration menu is exited.
The keys are used for navigation, and for configuring settings. The functions of the navigation keys vary from
menu to menu. The functions of the keys appear in the display as follows:
5: Navigate up.
6: Navigate down.
3Back: Move up one level within the menu.
7Run: Switch to the display mode.
Selection is acknowledged with the enter key.
Important: Do not use any sharp objects to press the keys when configuring settings,
because they might otherwise be damaged.

6.2. Teach-In
The Sensor is set up with the help of the teach-in menu.
Function Description
T Normal Normal Teach-In
The object is taught in by pressing
the T key:
• Align the spot to the object.
• Briefly press the T key.
èThe switching distance to
the object is set.
• If necessary, readjust the
switching distance with the help
of the “Potentiometer” menu item.
T Minimal Minimal Teach-In/Glass recognition
The object is taught in by pressing the T key:
• Align the spot to the object.
• Briefly press the T key.
èThe switching distance to the
object is set.
• If necessary, readjust the
switching distance with the help
of the “Potentiometer” menu item.
T Dynamic Dynamic Teach-In
The Sensor enters a recording phase when the T1 key is pressed, and
the minimum and maximum signal strength are saved to memory.
• Align the spot to the background
(e. g. conveyor belt).
• Briefly press the T1 key.
• Move objects through the light beam.
• Briefly press the T2 key.
èThe switching point is set
automatically between the minimum and maximum signal strength
saved to memory during the recording phase.
