1General
The LLD-150-PROF2are Laser sensors to measure distances from 0.1 m to
more than 100 m with pinpoint accuracy.
A given target can be clearly identified with the help of a red Laser sighting
point. In terms of operating reach, the LLD-150-PROF2
performs depending on the reflectance, morphology and qualities of the
target to be measured.
The sensor works based on comparative phase measurement. It emits
modulated Laser light which is diffusely reflected back from the target with a
certain shift in phase to be compared with a reference signal. From the
amount of phase shift, a required distance can then be determined with
millimeter accuracy.
Figure 1 : Measurement principle
A distance measuring cycle can be triggered in three different ways:
By sending a command from the PC or another equivalent control
unit
By making appropriate prior parameter settings for the auto start
command and applying supply voltage
By external triggering (in remote-trigger mode).
For a more detailed description of these three trigger options, you should
consult chapter 8, Parameters and Control via RS232 of this User Manual.

LLD-150-PROF2Manual General

Special performance features are:
Provides high accuracy and great reach under extreme
outdoor temperatures.
Works in a wide range of operating voltages from 10 V= to 30 V= from

or a DC power pack.
Features consistently low power consumption of <3.5 W1(without IAlarm)
Up to 30 m reach for distance measurement, with potential for more
than 100 m reach if additional reflectors2are mounted onto the
target (depending on reflectance and environmental conditions).
Visible Laser beam for easier sighting.
Output and control via Profibus DP
Measured values can be displayed in meters, decimeters, centimeters,
feet and inches due to.
Option for remote triggering of a measurement from an external
trigger device.

2Safety Instructions
2.1 General Safety Instructions
These safety and operating instructions should be carefully read and followed
during practical work with the LLD-150-PROF2.
There is danger of Laser radiation or electrical shock. For necessary
repair work, the LLD-150-PROF2may not be opened by anyone
other than Manufacturer 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 LLD-150-PROF2.
Cable connectors must not be plugged or unplugged under voltage.
Remember to turn voltage supply off before you begin working on cable
connections.
2.2 Intended & Conforming Use
Measurement of distances
Special measuring functions
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 LLD-150-PROF2in 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 LLD-150-PROF2must not be carried out by
anyone other than authorized personnel.

LLD-150-PROF2Manual Safety Instructions
Page 9
Refrain from using the LLD-150-PROF2 without certified
protection in an explosive environment
Measurement with the LLD-150-PROF2 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
2.4 Laser Classification
The LLD-150-PROF2is a Class 2 laser product, ≤1 mW as stipulated in
EN60825-1:2007, Class 2.
Caution:
There is Class 2 Laser radiation. Do not stare into beam!
Figure 2 : Warning Sign Laser Radiation Class 2
The Laser power is limited to maximum 1 mW. The Laser radiation is visible. A
short-term exposure (duration up to 0.25 s) is harmless to the eye.

Safety Instructions LLD-150-PROF2Manual
Page 10 ASTECH GmbH
Users are instructed by Laser warning sign (see Figure 2) to do not stare into
the beam. They have to protect themselves by turn the head and/or closing
the eyes and by avoid a long look into the beam.
Do not direct the Laser beam onto persons.
The sensor can use without any additional safety protection.

Page 17
with interfering high-frequency electromagnetic radiance. As a result, this
interface should only be used for configuring the LLD-150-PROF2.
Please configure using the programming cable and the LDMTool program.
Following successful configuration, remove the programming cable and
protect the terminal with a sealing plug.
Note: Please configure the LLD-150-PROF2prior to connecting
the Profibus. The receiving line of the RS232 serial interface
is deactivated after connecting to the Profibus master.
Please observe the RS232 standard. The maximum extension of the RS232
lines is 15 m.

5.6 Shield and Grounding
Cable shields must be grounded with low resistance. Only high quality shielded
cables should be used.
Carrier bases and control boxes should have equal potential. Potential
differences could lead to electrical currents and may cause EMC problems (no
correct measurement function or switching the gauge off or on is necessary).
If no potential equalization is possible, then mount the LLD-150-
PROF2 isolated from the carrier base (use nylon screws and washers).
Connect the screen with mass to the cable end. This way of assembly should
also be used when installing the LLD-150-PROF2inside vehicles.

Start up LLD-150-PROF2Manual
Page 20 ASTECH GmbH
7Start up
Ensure that all cable ends are protected against short circuit prior to turning
on the power supply!
Connect cable terminals as required for the particular operating mode. A pole-
reversal protection is included so as to prevent the destruction of electronic
components.
Connection to the Profibus master should only take place following start up!
Note: Please turn on the LLD-150-PROF2prior to connecting
the Profibus. The receiving line of the RS232 serial interface
is deactivated after connecting to the Profibus master.
Turning on the LLD-150-PROF2requires a PC with a corresponding
COM1 data interface, an optional programming cable and a
terminal programme. We recommend the use of the following programme:
LDMTOOL (Version 4.5 or higher).
When turning on the LLD-150-PROF2, it must be properly installed at
the designated operation site, aimed at the target, and kept in a
stable position. Targets to be measured (e.g. machine or system components)
should preferably have a light and homogeneous surface. Several optional
reflex foils are available.
Caution: Do no use any retro reflectors!
Alignment of the LLD-150-PROF2is facilitated by a visible laser
beam12 that can easily be turned on from a PC.
Operating voltage supply occurs via the power supply terminal (see Chapter
5).
