1 General
The LDS10A is an industrial grade distance sensor using advanced
measurement and detection capabilities based on patented signal processing
algorithms. It provides different interfaces to transmit the detection results to
post processing unit like PLCs in industrial applications.
The implemented sensing technology is based on infrared LED illumination
and the time-of-flight of light principle. The LED emitters illuminate the area of
interest (pulsed at high frequency) and the single channel sensor receiver
collects the backscatter of the emitted light and measures the time taken for
the emitted light to return back to the sensor. A single photodetector is used
and provides a full-beam sensing module. Oversampling and accumulation
techniques are used to provide extended resolution and range.
2 Safety Instructions
2.1 General Safety Instructions
These safety and operating instructions should be carefully read and followed
during practical work with the LDS10A.
There is danger of electrical shock. For necessary repair work, the
LDS10A may not be opened by anyone other than authorized
personnel. Unauthorized intervention into the inner product space
will void any warranty claims.
Compliance with all specified operating conditions is necessary.
Failure to observe advisory notes or nonconforming product usage may cause
physical injury to the user or material damage to the LDA10A.
Cable connectors must not be plugged or unplugged under voltage.
Remember to turn voltage supply off before you begin working on cable
connections.

Compliance with prescribed temperatures for operation/storage
Operation at correct voltage level
Application of specified signal levels to the appropriate data lines
2.3 Nonconforming use
Do not operate the LDS10A in any other way than described under
"Intended & Conforming Use" above and only in a proper working
condition
Safety devices must not be defeated or otherwise rendered
ineffective
Information and warning signs must not be removed
Repair work on the LDS10A must not be carried out by anyone
other than authorized personnel.
Avoid using the LDS10A without certified protection in an explosive
environment
Measurement with the LDS10A pointed at the sun or other strong
light sources may produce faulty results
Measurement of targets with poor surface reflectance in a strongly
reflecting environment may also result faulty measurements.
Measurement of strongly reflecting surfaces may deliver faulty
results.
Measurement performed through transparent optical media, for
example glass, optical filters, Plexiglas, etc. may equally produce
incorrect results.
Measurement on translucent objects (materials allow light to pass
through, but are not transparency, e.g. polystyrene, wax, different
plastics etc.) can give a too large measured value, since also light is
reflected by deeper layers
Rapidly changing measuring conditions are likely to falsify the result
of measurement

5.2 RS485 connection
The serial data interface of the LDS10A works according to the RS485-standard
(EIA-485) with two data lines with inverse polarity. It provides fieldbus
capabilities with multiple access and device identification by address.
The used protocol is Modbus RTU with binary data transmission. The
communication setup is as follows:
Baudrate: 19.200 baud
Parity: even
Start/Stop bits: 1 Stop Bit
The signal lines of the RS485 interface should not be left open. If not in use it
is recommended to connect a termination resistor of 120 Ω between the
signal lines A and B.
5.3 Analog current output
The purpose of the analog output QA is to allow transmission of measured
values as analogue current value. QA can be configured to a range of
4 mA … 20 mA (factory setting) or 0 mA … 20 mA. In second case the output
current can be transformed to 0-10V by a 500 Ω precision resistor. The
parameter QA_KBYTE controls the current range of QA.
Figure 3 : Wiring diagram of analog output
Page 15
LDS10A Manual Electrical Connection
ASTECH GmbH Page 15
The current is proportional to the measured target distance. This applies
within a distance interval that is marked by the two limiting parameters
QA_LOW and QA_HIGH, where QA_HIGH may be greater or smaller than
QA_LOW. The output current value for 4 mA … 20 mA output is calculated
according to this equation:
QA_LOW < QA_HIGH: IOUT[mA] = 4 mA + 16 ∙ (
Distance − QA_LOW
QA_HIGH - QA_LOW
) ∙ mA
QA_LOW < QA_HIGH: IOUT[mA] = 20 mA - 16 ∙ (

5.4 Digital switching outputs Q1 and Q2
With the help of a user-selectable distance threshold, the switching outputs
Q1 and Q2 can be set to monitor objects or conditions for positive or negative
overstep.
Using the digital switching outputs, objects can be monitored for excision of a
threshold value. To do this, parameter settings for a measurement window
are required. Settings for this window can be made with four parameters:
Qx_ON, Qx_OFF, Qx_HYST, Qx_NONC (x=1 means Q1, x=2 means Q2)
The range which will be subject to monitoring begins at Qx_ON and ends at
Qx_OFF. Switching transitions can be set via parameter Qx_HYST.
All distance parameters are given in millimeters.
The logic state of the switching output is determined by the parameter
QX_NONC. See chapter 7 for more information about parameterization of Q1
and Q2.

6 Start-up and measurement principle
6.1 Start up
Make sure that all cable ends are protected against short circuit effects before
you turn on power supply!
Connect cable terminals as required for the particular operating mode. To
prevent short circuits, you should seal unused cable ends!
For starting up, a PC with RS485 data interface or suitable USB-to-RS485
converter is required. We recommend the Windows program ProsoftP1
Version 2.17 or higher.
Figure 7 : Program ProsoftP1
As part of preparative actions, the LDS10A must be properly installed in the
designated working site, oriented onto the target and kept in a stable position.
The target to be measured should preferentially have a homogeneous, bright
surface.
Page 20
Start-up and measurement principle LDS10A Manual
Page 20 ASTECH GmbH
6.2 Measurement principle
The measurement principle of the LDS10A consists of a number of separate
data acquisition and processing algorithms.
Signal Acquisition
The signal acquisition module samples the signal of the photodiode element
using a patented oversampling and accumulation strategy to maximize the
signal resolution and the signal to noise ratio. It provides the light intensity
received by the sensor as a function of the time (corresponding to distance
knowing the speed of light) also called full-waveform signal. This fullwaveform signal allows the use of advanced signal processing techniques to
extract the distances of the objects and other useful information about the
scene.
Static Noise Removal
The static noise removal algorithm removes, as its name indicates, the static
noise in the full-waveform signal induced by undesirable light reflections due
to sensor enclosure or electromagnetic interferences. This algorithm increases
drastically the distance measurement accuracy and linearity. The static noise
shape is learned during a calibration procedure during which the waveform of
the signal is captured while the reception lens of the sensor is shielded from
the backscattered light. The sensor comes with a static noise factory
calibration.
Pulse Detection
The objects in the sensor field of detection create a particular signature in the
full-waveform signal called pulses. The pulse detector analyses the fullwaveform signal in order to recognize these pulses and compute their
distance. By nature, time-of-flight sensor using full-waveform analysis is able
to detect several distinct objects with a single photodiode element.
The detected pulses have specific amplitudes based on their distance from the
sensor and on the reflectivity of the objects. It is well known that pulses of
small amplitudes do not lead to accurate and precise distance measurements.
Consequently, the algorithm removes all pulses with amplitudes under a given
threshold.
Page 21
LDS10A Manual Start-up and measurement principle
ASTECH GmbH Page 21
Saturation Compensation
The algorithm classifies the detected pulses based on their shape. The LDS10A
determines which pulses are saturated and which have a normal shape.
Saturated pulse occurs when the signal backscattered by the object is so
strong that the full-waveform signal is clipped. If not treated, this
phenomenon creates an important degradation of the distance measurement
accuracy. It is why a saturation compensation algorithm is executed when
saturated pulses are detected. This innovative algorithm uses a sophisticated
approach to provide distance measurement accuracy better than 10 cm even
with a strongly clipped signal.
Temperature Compensation
The signal processing algorithm also embeds an advanced temperature
compensation scheme which attenuates the distance measurement drift over
large and sudden sensor temperature changes. With this algorithm, the
distance measurements stabilize inside 1 cm in less than 10 seconds on cold
sensor startup. The temperature compensation also ensures optimal accuracy
over the full operating temperature range.
Smoothing
The smoothing algorithm reduces the distance measurement jitter. It can be
seen as a recursive average filter which continuously adapts its cutoff
frequency (or averaging history length) as a function of the current
measurement noise. This innovative algorithm increases the precision of the
device (decreases the standard deviation of the measurements). The level of
smoothing of the algorithm can be adjusted to fit the requirements of the user
applications, please see section7 for more details.
Automatic LED intensity control
The automatic LED intensity control adjusts the intensity of the LEDs in real
time in order to maintain optimal pulse magnitudes at all times. For instance,
if pulses become suddenly saturated, the sensor will decrease automatically
the intensity of the LEDs to a level that ensures optimal distance measurement
accuracy.

Start-up and measurement principle LDS10A Manual
Page 22 ASTECH GmbH
6.3 Measurement rate
The sensor acquires a base input waveform at a rate of 72131 Hz
(44MHz/610). Multiple acquisitions are used to perform accumulations and
oversampling and generate a final waveform, which is processed afterwards to
detect the presence of objects and measure their position.
The final measurement rate is therefore:
Measurement rate =
𝑏𝑎𝑠𝑒 𝑟𝑎𝑡𝑒
𝑎𝑐𝑐𝑢𝑚𝑢𝑙𝑎𝑡𝑖𝑜𝑛𝑠 ∙ 𝑜𝑣𝑒𝑟𝑠𝑎𝑚𝑝𝑙𝑖𝑛𝑛𝑔
For example, with 256 accumulations and an oversampling value of 8:
Measurement rate =
72131 𝐻𝑧
256 ∙ 8
= 35.22 𝐻𝑧
Page 23
LDS10A Manual Start-up and measurement principle
ASTECH GmbH Page 23
The configuration software ProsoftP1 automatically calculates the most
suitable combination of accumulations and oversampling according to the
selected measurement rate.
