Obligation of the operator before start-up2.2
As an electronic device the measuring system is subject to the regulations of the EMC Directive.
It is therefore only permitted to start up the measuring system if it has been established that the
system/machine into which the measuring system is to be fitted satisfies the provisions of the EU EMC
Directive, the harmonized standards, European standards or the corresponding national standards.
General risks when using the product2.3
The product, hereinafter referred to as "LLB device"or "LLB sensor", is manufactured according to
state-of-the-art technology and accepted safety rules. Nevertheless, improper use can pose a
danger to life and limb of the user or third parties, or lead to impairment of the measuring
system or other property!
Only use the measuring system in a technically faultless state, and only for its designated use, taking
safety and hazard aspects into consideration, and observing this User Manual! Faults which could
threaten safety should be eliminated without delay!
Safety information's2.4
Danger of physical injury and damage to property !
Do not point the viewfinder directly at the sun, the viewfinder functions
as a magnifying glass and can injure eyes and/or cause damage
inside the LLB.
De-energize the system before carrying out wiring work or opening
and closing electrical connections.
Do not carry out welding if the measuring system has already been
wired up or is switched on.
Ensure that the laser warning symbol on the measuring system is well
visible anytime.
No use of accessories from other manufacturers.
Ensure that the area around the assembly site is protected from corrosive
media (acid, etc.).
The measuring system contains electrostatically endangered circuit elements
and units which can be destroyed by an improper use.
Contacts of the measuring system connection contacts with the fingers are
to be avoided, or the appropriate ESD protective measures are to be
applied.

Disposal
If disposal has to be undertaken after the life span of the device, the
respective applicable country-specific regulations are to be observed.
Cleaning
Clean the lens opening of the measuring system regularly with a damp
cloth. Do not use any aggressive detergents, such as thinners or
acetone!
Eye injury from laser radiation!
The measuring system functions with a red light laser Class 2. In the
case of Class 2 laser devices, the eye is not endangered if the exposure
to the laser radiation is very brief (up to 0.25 s) and accidental. For this
reason, devices of this class can be used without additional protective
measures, provided the application does not require one to look into the
laser beam deliberately for longer periods, i.e. 0.25 s, or to look
repeatedly into the laser beam or the reflected laser beam.
The existence of the blinking reflex for the protection of the eyes may not
be assumed. Therefore eyes should be closed consciously, or the head
should be turned away immediately!
The measuring system must be installed in such a way that the exposure
of persons to the laser beam can only occur accidentally.
The laser beam must only extend as far as is necessary for the range
measurement. The beam must be limited at the end of the useful range
by a target area in such a way as to minimize the danger from direct or
diffuse reflection.
The area outside the operating range where the unshielded laser beam
falls should be limited as far as possible and should remain out of
bounds, particularly in the area above and below eye level.
Heed the laser safety regulations according to DIN EN 60825-1 in their
most current version.
Observe the legal and local regulations applicable to the operation of
laser units.

Laser classification2.5
The LLB device produces a visible laser beam, which emerges from the front of the instrument.
It is a Class 2 laser product in accordance with:
IEC/EN 60825-1:2014 ”Radiation safety of laser products”
It is a Class II laser product in accordance with:
FDA 21 CFR 1040.10 and Laser Notice 50 (US Department of Health and Human Service,
Code of Federal Regulations)
Laser Class 2/II products
Do not stare into the laser beam or direct it towards other people unnecessarily. Eye protection is
normally afforded by aversion responses
including the blink reflex.
Looking into the laser beam may be hazardous to the eyes.
Do not look into the laser beam. Make sure the laser is aimed above or
below eye level. (particularly with fixed installations, in machines, etc.).
Do not look directly into the beam with optical aids (binoculars,
telescopes) can be hazardous

Hazards in use2.8
The absence of instruction, or the inadequate provision of instruction,
can lead to incorrect or prohibited use, and can give rise to accidents
with far-reaching personal, material and environmental consequences.
All users must follow the safety instructions given by the manufacturer
and the directions of the person responsible for the instrument.
Beware of erroneous distance measurements if the instrument is
defective or if it has been dropped or has been misused or modified.
Carry out periodic test measurements, particularly after the instrument
has been subject to abnormal use, and before, during and after
important measurements.
Make sure the LLB device optic is kept clean.
If labels are hidden when the LLB device is installed, this could lead to
dangerous situations.
Always ensure the visibility of LLB device labels at all times or add labels
in accordance with the local safety regulations.
When using the instrument for distance measurements or for positioning
moving objects (e.g. cranes, building equipment, platforms, etc.)
unforeseen events (e.g. breaking the laser beam) may cause erroneous
measurements.
Only use this product as a measuring sensor, not as a control device.
The system must be configured and operated in such a way that no
damage will occur in the event of an erroneous measurement,
malfunction of the device or power failure due to installed safety
measures (e.g. safety limit switch).
Operate the equipment appropriately in accordance with the regulations
in force.
Always prevent access to the equipment by unauthorized personnel.
Be careful when pointing a telescope towards the sun, because the
telescope functions as a magnifying glass and can injure eyes and/or
cause damage inside the LLB device.
Do not point the telescope directly at the sun.
