accurate as of the release of this manual. To find the newest information about this
product, refer to www.aerotech.com.
If you do not understand the information in this manual, contact Aerotech Global
Technical Support.
IMPORTANT: This product has been designed for light industrial manufacturing or
laboratory environments. If the product is used in a manner not specified by the
manufacturer:
lThe protection provided by the equipment could be impaired.
lThe life expectancy of the product could be decreased.
DANGER: To decrease the risk of electrical shock, injury, death, and damage to the
equipment, obey the precautions that follow.
lElectrical installation must be done by qualified personnel.
lBefore you do maintenance to the equipment, disconnect the electrical power.
lBefore you connect wires to this product, disconnect the electrical power.
lDo not connect or disconnect electrical components, wires, and cables while this
product is connected to a power source.

Laser Safety
It is the responsibility of the user to provide the necessary conditions for safe operation of a laser
system and to safeguard the work area against the dangers that can be caused by laser radiation. The
user must ensure compliance with all local and national regulations.
Although the scan head by itself does not emit laser radiation, the user must undertake a thorough
analysis of system safety before they operate the AGV3D in conjunction with a laser source. Important
information for performing this analysis is presented in this manual. Additional information may be
found in the corresponding documentation supplied by the manufacturer of the laser source.
Classes of Lasers
The AGV3D series scan head can be used with a variety of lasers. Each laser is assigned a particular
hazard level, which is indicated by the Laser Class label that is affixed to the device near the location
where laser radiation is emitted. Brief descriptions of each of the various radiation classes are presented
in the table below.
Note that in addition to the dangers of radiation, lasers can pose further dangers, such as the risk of
electrical shock or the generation of poisonous fumes.
Classifications of Laser Devices
Class Danger
Class I Inherently safe; no possibility of eye damage during normal operation.
Class IIa Requires in excess of 1000 seconds of continuous viewing to cause eye
damage.
Class II The blink reflex will prevent eye damage, unless the person deliberately
stares into the beam for an extended period of time.
Class IIIa
Mostly dangerous in combination with optical instruments which change
the beam diameter or power density. However, even without optical
enhancement, direct contact for over two minutes could cause eye
damage.
Class IIIb Direct exposures of 0.01 second or less could cause eye and skin damage.
Class IV Direct or scattered radiation without optical enhancement could cause eye
and skin damage.

Laser Area
The area in which the maximum permitted radiation value can be exceeded is defined as the laser area.
In general, a laser area is applicable to Class IIIa, IIIb and IV laser systems. A laser area can also be
produced if you focus the beam of a Class I, IIa, or II laser device.
The AGV3D can aim the laser beam over an approximately pyramidal volume. When the scan head is
used in conjunction with a laser device that can generate a sufficiently intense beam, a laser area will be
produced that includes the aiming volume as well as the reflections from all objects that can be exposed
to the radiation. It is important to note that even apparently diffuse surfaces can reflect laser radiation
and a laser beam that has been reflected several times can still be dangerous.
The laser area must be designated by suitable warning signs or lamps and protected by appropriate
shading and interlock switches.
