Page 5: Overview
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. -
Page 6: Safety Advice
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. -
Page 7: Laser Class
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- mended to store the unit inside the transport packaging until it is used. Please observe the storage conditions. -
Page 8: Intended Use
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 >... -
Page 9: Warning Signs And Type Plates
3.3 Warning signs and type plates Laser label The LLD-500 works with a class 2 laser. 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 drugs. -
Page 10: Device Description
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. -
Page 11: Mechanical Installation
4.3 Mechanical installation Der The LLD-500 can be screwed on using 3 (underside) or 2 M6 fastening screws respectively (length to be chosen depending on the counter piece). 3 M6 fastening screws plus washers and washer springs are included in the scope of delivery. -

Page 15: Ssi Synchronous Serial Interface
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). - Page 16 Figure 7: Wiring of SSI and cable jack pin The measuring mode will be defined with command AUTOSTART AS. Please note that by using of parameter measurement window MW (chapter 6.4.6) and / or offset OF (chapter 6.4.9) the distance output value has to be in the positive range (distance value > 0). Otherwise the SSI output will be 000000.

(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). -

When starting a continuous measurement using the integrated display, you need to define if the LLD-500 should measure based on the operating mode DT or CT. The operating mode is selected via the command MCT. When starting a measurement using the display, the predefined operating mode will be applied as a rule. -

6.5 Operating modes 6.5.1 DM – Individual distance measurement The LLD-500 will perform exactly one measurement and then wait for new instructions. The duration of the measurement depends on the number of preset measuring values SA and the preset measuring frequency MF. - Page 34 Example response (setting SD1 1 1 0, MUNm): d002.0305, 02736, and 00029 Output format decimal (d) Distance 2,0305 m Signal quality 2736 Temperature 29 °C Remarks: In case of poor target reflectivity, it cannot be guaranteed at 100 % that the respective measurement will be completed within a period of time of 0.01 s (100 Hz).

Page 35: Ct - Continuous Tracking
Distance is outside of the measurement window MW. 6.5.3 CT – Continuous tracking The LLD-500 performs an uninterrupted continuous measurement, adjusting the laser parameters (unambigu- ous ranges) in relation to the target only every 6 seconds or when an obvious distance measurement error has occurred. -
Page 36: Q1/Q2/Q3 - Switching Output
6.6 Q1/Q2/Q3 – Switching output The switching outputs Q1, Q2 and Q3 show distance information as logic switching information. They signalize when values are above or below a preset switching range subject to hysteresis. Hence, they are perfectly suita- ble for the direct further processing of monitoring variables such as filling level or object detection. Parameteri- zation is done via the serial interface. - Page 37 Figure 10: Switching behavior and parameters of the switching outputs Low = 0 U < 1 V U = operating voltage – 1V High = 1...

After installation of a Profibus master, product of softing, the related drivers (also see 2.4.), the service program for lasers LLD-150-PROF and LLD-500 (SL5.EXE) can be started. The program as such does not need an in- stallation (it is linked statically). Only the papi.dll for the Profibus must be placed in the folder. - Page 55 3. Press the Scan for Slave button A search of the bus is made and the first LLD-500 found is selected as slave. If the slave address (‘se- lect addr :’) is changed, a diagnosis request is sent to the slave and the PNO Ident of the slave dis- played when the reply is received.
