3 Intended use
The WLL80 fiber-optic sensor is an opto-electronic sensor which – in combination with fibers – is used for optical,
non-contact detection of objects.
A fiber-optic sensor is designed for mounting and may only be operated according to its intended function. For this
reason, the fiber-optic sensor is not equipped with direct safety devices.
The system designer must provide measures to ensure the safety of persons and systems in accordance with the
legal guidelines.
SICK AG assumes no liability for losses or damage arising from the use of the product, either directly or indirectly.
This applies in particular to use of the product that does not conform to its intended purpose and is not described
in this documentation.
If the product is used for any other purpose or modified in any way, any warranty claim against SICK AG shall
become void.

5.5 Ambient temperature
Max. output current: 20mA.
Ambient temperature during operation:
-25°C ... +55°C1
-13°F ... +131°F1
1Air humidity: 35 ... 85%
5.6 Alignment
When using the WLL80 fiber-optic sensor with through-beam fibers, align the sender fibers with the receiving
fibers. Select the position so that the emitted light beam hits the receiver. Tip: Use white paper or a reflector as an
alignment aid. The sender must have a clear view of the receiver. There must be no object in the path of the beam
[see figure 8]. You must ensure that the optical openings (fiber surfaces) of the fibers are completely clear.
Figure 8: Alignment of through-beam fibers
When using the WLL80 fiber-optic sensor with a proximity fiber, align the fiber to the object. Select the position
so that the emitted light beam hits the center of the object. You must ensure that the optical openings (fiber
surfaces) of the fibers are completely clear [see figure 9].

6.3 Multifunction input/output
The MF multifunction input/output can optionally be deactivated, or configured as an input or output.
MFIO/MFIn input functions:
•Teach-in
•Switching off the send LED (test)
•Reset counter value
•Reset extreme value memory
MFIO/MFOut output functions:
•Operational safety alarm (Quality of Run Alarm)
•Digital output channel 1
•Response signal for successfully performed teach-in(feedback)
•Error mode for signal when the measured value is outside the set range.
6.4 Wiring the digital input
The digital input can be used to start a teach-in, to switch off the sender as a test input, for an external input
signal (Smart Task), or to reset the counter value (Smart Task). Voltage level at the input starts the corresponding
function of the sensor.
Table 2: Electrical values
Signal voltage HIGH VCC: 24V 13.5V
VCC: 12V 9.0V
Signal voltage LOW VCC: 24V 8.0V
VCC: 23V 4.0V
Input impedance 100kΩ
6.5 Wiring the digital outputs
The number of digital inputs available at the connections will vary depending on the sensor, see "Connections",
page 14. If the allocated event occurs in the read process, then the corresponding digital output is live.
In each case, the digital outputs are short-circuit protected and overcurrent protected. The switching behavior is
selectable: push-pull, PNP or NPN (open collector).

7.2 Initial menu settings
Some initial settings need to be configured (during initial commissioning or after an initialization) to make the
sensor ready for operation. These defaults specify the parameters required for operating the device. It is often the
case that only these parameters need to be set in order to use the device.
