This sign indicates that special environmental protection guidelines must be observed when disposing of the
device.
1.3 General information
The laser distance meters of the LLD-500 series have been designed for application in industrial facilities.
Within the measuring range of 15 cm to 200 m the sensors work with a high accuracy of up to + 2.1 mm and at
a variably adjustable measuring frequency of maximally 100 Hz.
Due to the excellent optical measuring performance of the LLD the sensors can be used both indoors and out-
doors, even in case of a high percentage of constant light. Moreover, they can be used for measuring very hot
surfaces such as glowing steel.
When great distances of more than 50 m need to be measured, the sensor can be used in combination with a
reflector. Simple assembly and standard interfaces enable the quick integration of the device into complex
measuring and control systems.
Data can be displayed and parameters can be set using an internal keypad and display or an external communi-
cation program.

2. Safety advice
2.1 Basic safety advice
Please read the safety and operating advice carefully, and observe the advice when operat-
ing the LLD-500 laser distance measurement device.
Danger, laser radiation. The LLD-500 must not be opened unauthorized, otherwise laser ra-
diation can be emitted that can cause injuries to the eyes. Please observe all information and
guidelines for operating the laser.
Danger, electric shock
The LLD-500 may only be opened for repair purposes by the manufacturer. If the device is
opened arbitrarily without authorization, all warranty claims will expire.
The operating and storage conditions ( chapter 9) have to be observed. The non- observance
of this advice and the adverse use of the device can lead to injuries of the user or to damage
of the device.
Connectors may not be plugged or unplugged when voltage is applied.
All installation work may only be carried out when no voltage is applied.
The device may only be operated as intended and in faultless condition.
Safety installations must not be rendered ineffective.
Safety and warning signs must not be removed.
Protection degree:
In accordance with the protection degree IP67, the LLD-500 is protected against jet water
and dust, and against short submersion into water.
When operating the device under extreme outdoor environmental conditions, the use of addi-
tional weather protection is recommended (e.g. a cover plate with a short distance to the
LLD-500). Rapid temperature changes can lead to humidity entering the device.
If the device is exposed to humidity, the temperature difference between the de- vice and the
environment may be ± 5K maximum.
The device is not shatter-proof. Do not let the device fall onto the ground, and avoid any agi-
tation.
The device may not be used in explosive environments; otherwise there is the danger of
damage to the LLD-500 and the surrounding equipment, and of injuries of the user.

7
2.2 Laser class
Based on the standard EN 60825-1:2014 the LLD-500 is in correspondence with laser class 2.
When looking into the laser beam accidentally and for a short moment, the eye will be protected by
the eyelid closing reflex. The eyelid closing reflex can be affected by pharmaceuticals, alcohol and
other substances.
2.3 Transport and storage
The LLD-500 laser distance meter is delivered in standard packaging. All kinds of transport are permitted.It is recom-
mendedtostoretheunitinsidethetransportpackaginguntilitisused. Pleaseobservethestorageconditions.
2.4 Cleaning and maintenance
The LLD-500 does not require any maintenance. To ensure trouble-free measurements, the optical surfaces
through which the laser beam exits and enters must be free of deposits. Dust can be removed using an air
brush. In case of dirt that is hard to remove, please contact the manufacturer.
The device must not be cleaned using solvents or mechanical tools. Mechanical or electrical modifications of the de-
vice are not permitted.

3. Intended use
3.1 Operating and storage conditions
Operating temperature1
-10°C…+60°C(special type-40°C…+60 °C)
Storage temperature
-40 °C …+70 °C
Humidity
15 %…90 %,non-condensing
1Depending on the type of device
Explanation: The values specified as operating temperature descripe the temperature range in which the LLD
can be used according to the specification.
The operating temperature refers to the internal temperature of LLD and could be approx….
10 kelvins above the ambient temperature (see EN 60204-1).
If LLD-500 operates near the upper limit of temperature range (ambient temperature > 40
°C), the probability of measuring errors will be increased.
A permanent operation of LLD-500 at higher temperatures (ambient temperature > 40 °C)
shortens the lifetime of the sensor. For permanent operation of LLD-500 it is recom-
mended not to exceed an operation temperature of 50 °C, which correlates to a maximum
ambient temperature of 40 °C.
3.2 Improper use and possible error sources
•The unit may be used only as prescribed.
•Please do not remove any labels and type plates.
•Repair work must not be performed by the user. In case of questions or doubt, the manufacturer is to
be consulted. For contact data see section 2.5.
•In order to obtain correct measuring values the following advice is to be observed:
1. Measurements against the sun or onto surfaces with low reflectivity in very bright
environments can result in faulty measurements.
2. Measurements through glass, optical filters, Plexiglas or other translucent materi als are possible to
a limited extent but can result in measurement errors.

4. Device description
4.1 General information
The LLD-500 distance meter is available in different versions. Types can be selected based on the required interface
and on the temperature conditions at the place of application.
LLD-500 versions designed for an operating temperature of as low as – 40 °C can be used for applications outdoors
or in refrigerated warehouses. The heating element ensures the operating temperature of the components and free
optics (no condensation) of the LLD-500.
The required connecting cables are available with straight and angular plug-in connectors. In order to prevent the
direct incidence of extraneous light into the device optics, a light protector is available as well that can be screwed
onto the device. Devices with a cable length of up to 10 m are demonstrably EMC-safe.

4.9 SSI Synchronous Serial Interface
SSI will be parameterized via serial interface or the internal display of LLD-500
SSI data interface is optional for LLD-500 (please see the types and order numbers in chapter 4.2). At the
request of a SSI clock LLD-500 starts the output of measuring values and sends the data bit by bit from the shift
register of LLD-500 (Slave) to an external controller (Master).
It could be used all measuring modes of LLD-500. The active measurement mode will be set via serial interface
or Profibus or internal display.
Setup via serial interface → see chapter 6.4.22 SSI und 6.4.16 SE
Setup via internal display → Parameters / BUS / SSI / SSI mode
SSI works independent of Profibus interface.

The user is responsible for the application-specific cabling and for the parameterization of the Profibus
(optional), particularly of the slave address. Thus, the latter are taken as a given.
Where the LLD-500 is taken into operation for the first time, we recommend carrying through the configuration
steps at a laboratory or office.
The device can be configured using either the display or a communication program. For example, the program
HyperTerminal (included in Win32 operating systems) or any other communication program can be used.
In order to parameterize the device using a communication program, the LLD-500 must be connected to supply
voltage and a PC (also see Fig. 2 in chapter 4.4).
SSI and/or Profibus need to be set separately.
No.
Work step
1
Unpack the LLD-500, check it for damage.
2
Mount the LLD-500 at the target location (with 2 screws through the side face or 3 screws through
the bottom) --> see 5.1.
Roughly direct it at the target surface.
3
Plug and firmly screw on the interface cable in the de-energized condition.
4
Connect and firmly screw on the Profibus and SSI connections (optional).
5
Wire the open cable end. Energize. Green status LED must light up.
6
As soon as STATUS LED is green, the red laser beam will be visible. Precondition: AS DT (default
value). Mechanical fine adjustment can be executed.
7
Parameterize the LLD-500 via the menu navigation on the display. Alternatively parameterize the
device using a terminal program.
8
Activate the distance measurement mode (e.g. DT).
9
Start the distance measurement (laser is switched on). Measurement output and Status- LED must
be checked. Stop the distance measurement mode.
Alternative: Start measurement via Profibus.
The SSI measurement mode is to be defined in the AUTOSTART AS command.

6. Parameter setup and measuring operation
6.1 General information
The LLD-500 is parameterized using the serial interface or the display. Precondition for programming via serial
interface is a connec-tion provided by a terminal program (e.g. HyperTerminal --> see chapter 7).
The set parameters are stored in an EEPROM.
The last entered data will be available upon restarting.
► Retrieval of parameters
Input PARAMETER <ENTER> <ENTER> = CR = (0x0D)
► Setting of parameters
Input PARAMETER VARIABLE <ENTER>
The variables are described with the individual parameters.
Several variables are separated by spaces (0x20).
►Starting a measurement (operating mode) Input COMMAND<ENTER>
►Starting a measurement (operating modes) Input COMMAND <ENTER>
►Stopping a measurement <ESC> <ESC> = (0x1B)
►Distances are always entered in 0.1 mm (100 µm).
The scale factor SF has no influence on the input parameters.
Example: Input
3.20 m = 32000
The output values shown in the manual are examples. They may vary depending on the settings and environ-
mental conditions.
Whenever an incorrect or incomplete command is entered, the following responses are shown:
The input does not contain any parameter or command.
e.g.: HELLO<ENTER>
Parameter with current value Entry of a parameter with incorrect figure/ parameterization
e.g.:
Input: SAxxx<ENTER>
Output: SA 10 (where SA = 10 prior to input)
6.2 Measurement involving moving targets
Where measurements involve a moving object or the LLD-500 is moved during measuring, this will have an im-
pact on the accuracy of the measured value.
This must be observed particularly when calculating average values (parameter SA).
Measurement jumps and/or considerable changes in the reflectivity of the target surface can prolong the
measurement period.
In case of a fixed measuring frequency (parameter MF), this may result in no measured value being generated
within the predefined time. A warning or error message will be displayed instead.
