FIRST STEPS
WayCon Positionsmesstechnik GmbH would like to thank you for the trust you have placed in us
and our products. This manual will make you familiar with the installation and operation of our laser
sensors. Please read this manual carefully before initial operation!
Unpacking and checking:
Lift the device out of the box by grabbing the housing. Please pay attention not to touch the laser
window. After unpacking the device, check it for any visible damage as a result of rough handling
during the shipment. Check the delivery for completeness.
If necessary consult the transportation company, or contact WayCon directly for further assistance.
SAFETY INSTRUCTIONS LASER CLASS 2
• The irradiation can lead to irritation especially in a dark environment. Do not point at people!
• Caution: Do not look into the beam!
• Maintenance and repairs should only be carried out by authorized service personnel!
• Attach the device so that the warning is clearly visible and readable.
• Caution: Use of controls or adjustments or performance of procedures other than those specied
herein may result in hazardous radiation exposure.
INSTALLATION
For triangulation sensors like the LAS, there is a simple rule, that the distance between sensor and
target should be as small as possible. The smaller this range the better the linearity and accuracy of
the sensor.
The receiver optics must be able to detect the light spot directly (gures 1 and 2). The light path must
not be blocked, as shown in gure 3.
For highly polished or mirror-like objects it is important to keep the direct reection away from the
detector. In these cases, it is recommended to slightly tilt the sensor (gure 4).
Optimum results are obtained by transverse installation of the sensor with respect to the target
movement (gure 5).

ELECTRICAL CONNECTION
General information
• If external Teach-In option is not used, the Teach-In wire must be attached to GND. More information
about the Teach-In function can be found in the teaching guide.
• The max. accuracy will be reached >15 minutes after power on.
• Electromagnetic compatibility: The sensor must be grounded correctly; a shielded cable is highly
recommended.

Alarm output
The alarm output is activated, as soon as the
object is outside of the measurement range, or
if the received signals are useless for a distance
measurement (too low, or too high). In both
cases the analog output signal is 4 mA / 0 V.
The sensor has no internal hold function to
bridge missing measurement signals.Therefore,
it may happen in critical applications (extremely
bright surfaces) that the output shortly drops to
4 mA / 0 V, when the measurement signal gets
lost. By checking the status of the alarm output
before making a measurement, this false output
signal can be identied.

TROUBLESHOOTING
Error Possible cause Correction
The sensor does not
measure
The sync. input or the teach-in wire is
connected to + V.
Connect the sync. Input or the teach-in
wire to 0 V.
The receiving beam is covered by an
object / edge / step.
Make sure that no object blocks the laser
beam. Is the laser sot visible for the sensor?
No receiving signal (transparent or
highly reective object).
See gure 4 (above). If possible, use a
diuse reecting surface (e. g. white paint).
The sensor has incorrect
measuring values
Mutual optical interferences between
two or more sensors.
Switch o close sensors that might
inuence the receiving unit of the sensor.
Strong ambient light (e. g. direct sun
light).
Prevent ambient light with a shield.
Semi-transparent, transparent, or
highly reective objects.
Make sure that the laser spot falls on a
diuse reecting target.
The sensor does not reach
the specied accuracy
Rough surface A sensor with a laser line will work better.
Colour edges Mount the sensor the correct way.

MAINTENANCE
The window of a laser sensor should be clean, in order to get the best possible measurement results.
Dust, dirt or drops of liquid can impair the measurement result and in the worst case cause a wrong
measurement result.
The following cleaning methods are suitable:
1. dry cleaning using a soft brush.
2. with a dry, soft, antistatic cloth.
3. wet cleaning with clear water, about 30 °C, if necessary add a bit of mild soap.
Do not use glass cleaner!
