1. General Information
The LLD is a laser distance sensor to measure distances from 0.1 m to maximum 150 m with pinpoint accuracy.
A given target can be clearly identified with the help of a red laser sighting point. In terms of measurement
range, the LLD performs depending on the reflectance, morphology and qualities of the target to be measured.
The Laser sensor works based on comparative phase measurement. It emits modulated high-frequency 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 be determined with an accuracy of a millimetre.
A distance measurement can be triggered in four different ways:
•
By sending a command from the PC or another equivalent control unit
•
By making appropriate prior parameter settings for the autostart command and applying supply voltage
•
By external triggering (in remote-trigger mode)
•
Using the autostart trigger function.
For a more detailed description of these four trigger options, please see section 5. Operating Modes of this User
Manual.
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 an on board vehicle supply point,
an industrial direct voltage supply net or a DC power pack.
•
Features consistently low power consumption of <1.5 W (without I
Alarm
).
•
Up to 30 m reach for distance measurement, with potential for more than 150 m reach if additional
reflectors are mounted onto the target (depending on reflectance and environmental conditions).
•
Visible laser beam for easier sighting.
•
RS232 interface port for input of measuring functions and commands from, and output of measured
values to, a PC or a laptop.
•
Switching output and analog output are separately programmed.
•
Switching output with adjustable limit to indicate positive and negative exceeding of preselectable
distance range window by sighting distance.
•
Measured values can be displayed in meters, decimetres, centimetres, feet, and inches due to.
•
Option for remote triggering of a measurement from an external trigger device.
The LLD laser sensor is shipped in a rugged cardboard box with adequate padding for safe transportation.
2. Safety Instructions
2.1
Basic Information
These safety and operating instructions should be carefully read and followed during practical work with the LLD
There is danger of laser radiation or electrical shock. For necessary repair work,
the LLD may 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.
