seconds. It may pose a danger to the eyes and skin in the event of incorrect use.
■Do not open the housing. Opening the housing may increase the level of risk.
■Current national regulations regarding laser protection must be observed.
Caution – Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
It is not possible to entirely rule out temporary disorienting optical effects, particularly
in conditions of dim lighting. Disorienting optical effects may come in the form of 
dazzle, flash blindness, afterimages, photosensitive epilepsy, or impairment of color
vision, for example.
WARNING

field evaluation applications and are not suitable for measurement data output.
NOTE
For more information about the special functions of the LMS531 see "Parameterizing
the LMS531 variants for security applications", page 80.
3.2.3 Heavy Duty variants with ventilation element
The ventilation element ensures an improved pressure equalization and allows the
exchange of air and heat between the sensor housing and the environment. The
breathable membrane allows ambient air to either penetrate into the device, or escape
again depending on the prevailing ambient conditions. In particular for applications
with frequently changing environmental influences (e.g., large temperature fluctuations
or fast temperature changes) or with standing water, the membrane ensures a reliable
pressure equalization and thereby relieves the seals and adhesive joints of the sensor
housing. This can improve the expected service life of the device in the application.

1Ventilation element
Notes and recommendations:
•Do not affix any labels or stickers to the ventilation element or paint over the mem‐
brane. Longer moist periods and rapid temperature changes may briefly reduce
the availability of the device. This applies in particular to previously switched off
devices that are started in the application and were previously exposed to the
aforementioned environmental influences.
•In some circumstances, therefore, a period of time should be allowed before
measurement readiness of the device because any moisture in the housing must
first be taken up by the air in the housing, which is heated up through the
operation of the device, so that it can then escape via the ventilation element.
Depending on the nature of the precipitated moisture, this time period might be
several minutes or even up to hours. It is recommended that the LMS5xx variants
with a ventilation element be operated continuously during the application (contin‐
uous operation).
•It is recommended to connect the integrated sensor heating according to the
specifications in the operating instructions to ensure additional heat input at low
ambient temperatures.

3.2.4 Extended Range variants
The Extended Range variants feature a higher measuring range as well as an increased
sensitivity over the entire measuring range. This enables objects to be measured and
detected at larger distances and, in particular, makes it easier to detect objects with a
low remission factor.

The increased sensitivity is a preset, non-changeable device characteristic. This exten‐
sion can, in some circumstances, result in an increased sensitivity to interference, for
example fog, spray or rain, compared to the standard variants. The Extended Range var‐
iants are, however, designed to provide a good balance between sensitivity and availa‐
bility and have been optimized accordingly. Furthermore, the Extended Range variants
also feature all of the filtering options described in section Filter for preprocessing and
optimizing the measured distance values. This enables the sensor parameterization to
be optimally tailored to the application-specific requirements.
The Extended Range variants are Heavy Duty variants with a ventilation element, see
"Heavy Duty variants with ventilation element", page 14. For further details on the
technical data, see "Technical data", page 99.
NOTE
The Extended Range variants use different scaling factors for the data output via
telegrams and differ from the standard variants in this respect.
The distance values received via data output must be multiplied by the specific factor
applicable to the Extended Range variants see table 16, page 33.

3.5 Status indicators
Operator interface
The device works fully automatically in normal operation and requires no operator
intervention.
The SOPASET configuration software allows interactive configuration. For this, the
software runs on a computer which is connected to the device with one of the data
interfaces.
The graphical scan display in SOPASET is used to verify the generated measured
values and the measuring range online.
NOTE
Scans in SOPAS ET are not displayed in real time, but at a limited speed. Not all
measured values are displayed for this reason.
Status indicators
The LEDs and 7-segment display indicate the operational status of the device.

Display Description
1Device is either not in measuring mode (stopped by the user) or it is
running in measurement mode, but errors have occurred
2Off: No contamination
On (lit up) Contamination warning
On (flashing): Contamination error
3Device running in measurement mode without any errors
4Reserved
5The 7-segment display is used for diagnostics when errors or faults
occur see "Indicators in the 7-segment display", page 97.
6At least one field is breached see "Linking of evaluation cases at the
output", page 47.
It is recommended to also monitor the Device Not Ready operational status as well as
messages from the contamination measurement via the digital outputs of the sensor to
ensure the device readiness is continuously checked.
NOTE
As well as the standard indicators described below, the indicator functions of the LEDs
and the 7-segment display can be configured in SOPASET for the device (SOPASET:
Project tree, LMS…, Parameters, Network/Interfaces/IOs, Display).
For additional information, see "LED fault indicators", page 96.
3.6 Principle of operation
3.6.1 Measurement principle
The device is an opto-electronic LiDAR sensor that scans the outline of its surround‐
ings with the help of laser beams without making contact. The device measures its
surroundings in two-dimensional polar coordinates, relative to its measurement origin.
This is indicated by small markings on the sides of the optics cover. If a laser beam
strikes an object, the position of that object is determined in terms of distance and
angle.

3.6.2 Range finding
The device emits beams pulsed by a laser diode. If the laser beam is reflected by an
object, the reflected beam is received by the sensor.
The distance to the object is calculated on the basis of the time that the pulsed light
beam requires to be reflected and received by the sensor.
t

1Emitted pulse
2Receive pulse
3.6.3 Direction measurement
The emitted laser beams are deflected by an internal rotating mirror and scan the
environment in a circular motion. The measurements are triggered by an encoder in
regular angle increments.
The LMS5xx PRO/Heavy Duty measures with an adjustable scanning frequency of 25,
35, 50, 75 or 100Hz. A laser pulse and thus a measurement is triggered continuously
after each angle increment of 0.1667°, 0.25°, 0.3333°, 0.5°, 0.6667° or 1°.
In interlaced mode, the start angle of a measurement is cyclically shifted in order to
achieve an even finer angular resolution see "Interlaced mode", page 33.
The LMS5xx Lite measures at a configurable scanning frequency of 25, 50 or 75Hz
and at angle increments of 0.25°, 0.5° or 1°.
