switch points.

Product Description
Functions and operating modes
10 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.4 Operating principle
The FMCW radar (frequency modulated continuous wave) measures the distance to stationary
objects.
The sensor outputs a radar signal that changes in frequency. A periodic, linear frequency which
varies upwards and downwards is used to limit the frequency range and to simplify the signal
evaluation. The rate of change df/dt of frequency remains constant. Objects in the detection
range reflect the transmitted signal. The change in the signal delay and frequency of the reflec-
ted signal are used to determine the distance to the object.
The frequency modulated continuous wave radar therefore has a clear advantage over the
unmodulated continuous wave radar, which cannot detect distances.
4.5 Functions and operating modes
4.5.1 Setting options
The devices feature the following three setting options:
nSetting via IO-Link
nSetting via the touchpads
nSetting via FDT/DTM
4.5.2 Normal operation – run mode
The device detects the distance to the surface of the medium and shows the required switching
or analog behavior according to the factory set or customer-specific parameters. The measured
distance to the medium is shown in the display. The selected unit and the status of the existing
switching outputs are indicated via LEDs.
4.5.3 Programming mode
If the sensor is unlocked, the display switches to Programming mode after the [MODE] touch-
pad is pressed. All parameters and their associated values can be read and modified in Pro-
gramming mode. A short press of the [ENTER] touchpad displays the values of a parameter. The
[MODE] and [SET] touchpads are used to navigate in Programming mode.
4.5.4 Output functions – switching output
A window function and a hysteresis function can be set for the switching outputs.
Window function
The window function is used to teach a switching range in which the switching output takes on
a defined switching state. The switching range is defined by an upper and lower limit value. The
minimum distance between the limit values is 0.5 % of the measuring range. If the upper limit
value is changed, the lower limit value is automatically adjusted.

V01.00 | 2021/07 11
Hysteresis function
The hysteresis function is used to teach in a stable switching state that is not affected by sys-
tem-related fluctuations and the defined setpoint. The switching range is defined with a
switching point and a reset point. The minimum hysteresis is 0.5% of the measuring range. If
the switching point is changed, the reset point is automatically adjusted.

4.5.5 Output functions – analog output
The analog output of the LRS…LI2UPN8 sensors can be set as either a current or voltage
output. The measuring range can be defined as required.
The minimum distance between the start and end point is 500mm.
Current output
In the defined measuring range between ASP (analog start point) and AEP (analog end point),
the device supplies an analog current signal. The following output configurations can be set:
n4…20 mA (factory setting)
n0…20 mA
n20…4 mA
n20…0 mA
Voltage output
In the defined measuring range between ASP (analog start point) and AEP (analog end point),
the device supplies an analog voltage signal. The following output configurations can be set:
n0…10 V (factory setting)
n0…5 V
n1…6 V
n0.5…4.5 V
n10…0 V
n5…0 V
n6…1 V
4.5.6 IO-Link mode
The devices must be connected to an IO-Link master for operation in IO-Link mode. If the port is
configured in IOL mode, bidirectional IO-Link communication is provided between the IO-Link
master and the device. For this the device is integrated in the controller level via an IO-Link
master. The communication parameters are exchanged first of all; the cyclic data exchange of
the process data (process data objects) then starts.

12 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.5.7 SIO mode (standard I/O mode)
In standard I/O mode no IO-Link communication takes place between the device and the mas-
ter. The device only transfers the switching state of its binary outputs and can also be run via a
fieldbus device or controller with digital PNP or NPN inputs. An IO-Link master is not required
for operation.
The device parameters can be set via IO-Link and then operated at the digital inputs with the
appropriate settings in SIO mode. Not all functions and properties of the device can be used in
SIO mode.
4.5.8 Auto sensing function
When connected to an I/O module, the auto sensing function enables the device to support the
set switching output behavior (PNP/NPN) or analog output characteristics. The auto sensing
functions are activated by default.

5 Installing
The lens curvature does not have to be taken into account for the installation. The sensor de-
tects the surface of the medium nearest to the sensor and outputs the distance. Object reflec-
tions can be filtered out using the sensor parameters.
The sensors can be installed in any alignment according to application requirements. The radar
wave propagates perpendicular to the surface of the radar lens with an opening angle of ±3°.
The display of the unit can be rotated by 180° (see parameter DiSr). The maximum tightening
torque for fastening the sensors is 45Nm.
Multiple radar sensors can be mounted directly next to each other without the risk of any mu-
tual interaction between the devices.
Smin
Fig.7: Installing LRS510…
Install the sensor at the intended mounting location. Observe blind zone smin, in which no
object detection is possible.
For optimum operation, install the sensor in such a way that no foreign objects are loc-
ated in the detection range.
Install the sensor so that the limits of the detection range are not located on a container
wall.
Use short connection pieces to ensure unhindered signal propagation in the short range
(see range diagrams).
To prevent any disturbance signals do not direct the filling stream of the media through
the detection range of the sensor.
