Section 1
1 Laser Safety
1.1 General Information
The laser light sources used in LMI Sensors are semiconductor lasers emitting visible
light.
LMI Laser Sensors have a 2/ll, 3R/llla or 3B/lllb classi ication depending on model.
Class 2/ll and 3R/llla sensors are re erred to as “products” indicating that they ully
comply with the standards relating to laser products speci ied in IEC 60825-1 and U.S.
FDA CFR Title 21 Part 1040 except or deviations pursuant to Laser Notice No. 50,
dated July 26, 2001.
Class 3B/lllb sensors are sold only to quali ied OEM’s as “components” or incorporation
into their own equipment. The sensors do not incorporate sa ety items which the OEM is
required to provide in their own equipment (e.g. remote interlocks, key control). As such
these sensors do not ully comply with the standards relating to laser products speci ied
in IEC 60825-1 and FDA CFR Title 21 Part 1040.
Caution!
Use o controls or adjustments or per ormance o procedures other than
those speci ied herein may result in hazardous radiation exposure.

1.2 Laser Classification
1.2.1 Laser Classes
Class 2/ll laser products:
Class 2/ll laser products would not cause
permanent damage to the eye under
reasonably oreseeable conditions o
operation, provided that any exposure can
be terminated by the blink re lex (assumed
to take 0.25 sec). Because classi ication
assumes the blink re lex, the wavelength o
light must be in the visible range (400 nm to
700 nm). The Maximum Permissible
Exposure (MPE) or visible radiation or 0.25
second is 25 Watt per square meter, which
is equivalent to 1 mW entering an aperture
o 7 mm diameter (the assumed size o the
pupil).
Class 3R/llla laser products:
Class 3R/llla laser products emit radiation
where direct intrabeam viewing is potentially
hazardous, but the risk is lower than or
3B/lllb lasers. Fewer manu acturing
requirements and control measures or
users apply than or 3B/lllb lasers.
Class 3B/lllb laser components:
Class 3B/lllb components are unsa e or eye
exposure. Usually only ocular protection
would be required. Di use re lections are
sa e i viewed or less than 10 seconds.
Labels reprinted here are
examples relevant to the laser
classes. For detailed
speci ications observe the label
on your laser sensor

in the system design.
1.2.3 Class 3B/lllb OEM Responsibilities
LMI Technologies has iled reports with the FDA to assist the OEM in achieving
certi ication o their laser products. The OEM can re erence these reports by an
accession number that will be provided upon request.

9
Detailed descriptions o the sa ety items that must be added to the OEM design are
listed below:
Remote Interlock
A remote interlock connection must be present in Class IIIB laser systems. This permits
remote switches to be attached in serial with the keylock switch on the controls. The
deactivation o any remote switches must prevent power rom being supplied to any
lasers.
Key Control
A key operated master control to the lasers that prevents any power rom being supplied
to the lasers while in the OFF position. The key can be removable in the OFF position
but the switch must not allow the key to be removed rom the lock while in the ON
position.
Power-On Delays
A delay circuit is required that illuminates warning indicators or a short period o time
prior to supplying power to the lasers.
Beam Attenuators
A permanently attached method o preventing human access to the laser radiation other
than switches, power connectors or key control must be employed. On some LMI laser
sensors, the beam attenuator is supplied with the sensor as an integrated mechanical
shutter.
Emission Indicator
It is required that the controls that operate the sensors incorporate a visible or audible
indicator when power is applied and the lasers are operating. I distance (>2 m between
sensor and controls) or mounting o sensors intervenes with observation o these
indicators, a second power-on indicator should be mounted at some readily observable
position. When mounting the warning indicators, it is important not to mount them in a
location that would require human exposure to the laser emissions.
Warning Signs
Laser warning signs must be located in the vicinity o the sensor such that they will be
readily observed. Examples o laser warning signs are:

10
1.3 Requirements for Laser Systems Sold or Used In the USA
The OEM’s laser system which incorporates laser components or laser products
manu actured by LMI Technologies requires certi ication by the FDA.
It is the responsibility o the OEM to achieve and maintain this certi ication.
OEM’s are advised to obtain the in ormation booklet Regulations for the Administration
and Enforcement of the Radiation Control for Health and Safety Act of 1968: HHS
Publication FDA 88-8035.

2 Proper Handling and Precautions
2.1 System Installation
2.1.1 Component Grounding
All sensors should be grounded to the earth/chassis through their housing. For sensors
with through-hole mounts, this can be accomplished by using star washers on the
mounting bolts. The star washers must cut through the powder coating to provide
electrical conductivity rom the mounting hardware to the sensor housing. For sensors
with tapped hole mounts, conductive hardware must to be used between the sensor and
the rame. This must be checked with a multi-meter by ensuring electrical continuity
between the rame and the connector housing on the sensor. It is imperative that the
scan rame or chassis that the sensor is mounted to is connected to earth ground.
Master networking products should have the housing connected to earth ground. This
can be accomplished using star washers on the mounting holes or through the earth
ground connection located on the rear o the Master 1200 and 2400. FireSync
Networking products should be installed inside electrical cabinets that are suitably
grounded to earth ground.
2.1.2 Shielded Cable
LMI Technologies recommends the use o shielded cables in all environments to ensure
isolation rom electrical noise. The shield should be electrically connected to both the
sensor housing through the connector housing and to the electrical box containing either
the Master (network systems) or the power supply (standalone sensors).
LMI Technologies supplies both shielded FireSync cordsets and shielded FireSync cable
or building cordset.
2.1.3 Power Supply
The user must provide a suitable +48VDC power supply or the system capable o
handling an in inite capacitive load. These power supplies must be isolated such that DC
ground is NOT tied to AC ground. The power supply should be o a suitable capacity or
the size o the system.
LMI Technologies recommends the Phoenix Contact QUINT series o power supplies.

12
2.1.4 Uninterruptible Power Supply (UPS)
To maximize the li e o the sensor, LMI Technologies recommends the use o an on-line
double-conversion UPS whenever the quality o the electrical supply to the system is
poor. This includes but is not limited to when the electrical supply:
• contains high requency noise (due to other electronics, electric motors or other
actors)
• is prone to “brown-out” conditions or large voltage luctuations
• is prone to electrical surges or spikes due other components or electrical storms.
LMI Technologies recommends the Tripp Lite SU2200RTXL2UA UPS.
2.1.5 Installation Environment
To prevent damage to LMI 3D sensors and ensure reliable operation, avoid installing the
sensor in locations:
• that are humid, dusty, or poorly ventilated
• with a high temperature such as a place exposed to direct sunlight
• where there are lammable or corrosive gases
• where the unit may be directly subjected to vibration or impact
• water, oil, or chemicals may splash onto the unit
• where static electricity is easily generated
2.2 Temperature and Humidity
LMI 3D Sensors are rated or operation between 0- 50°C, and 25-85% Relative Humidity
(non-condensing).
2.3 Maintenance
LMI 3D sensors are high-precision optical instruments. To ensure the highest accuracy
is achieved in all measurements, the windows on the ront o the sensor should be kept
clean and clear o debris.
Use dry, clean air to remove dust or other dirt particles. I dirt remains, clean the
windows care ully with a so t, lint- ree cloth using an ammonia based cleaner. Ensure
that no residue is le t on the windows a ter cleaning.
2.4 Laser Lifetime
LMI Technologies uses semiconductor lasers in their 3D measurement sensors. To
maximize the li espan o the sensor it is recommended to turn o the laser by stopping
the sensor whenever it is not in use.
2.5 Avoid Flash Writes (Standalone Sensors only)
Operation parameters or standalone sensors are stored with lash memory inside the
sensor. Flash has an expected li etime o 100,000 writes. Avoid requent or unnecessary
write commands to the sensor to maximize the li etime o the sensor.

3 Getting Started
Warning! chroma+scan 3xxx sensors are class 3B/IIIb components. Please read
Section 1: Laser Sa ety above, and institute the necessary sa ety precautions be ore
turning these sensors on.
This section provides a brie introduction to the chroma+scan 3xxx. It identi ies the
components supplied by LMI Technologies, and the additional components required to
get a basic system up and running. This is ollowed by instructions on how to connect
these components together, and how to install and run our client so tware to acquire
basic pro ile data to ensure sensor operation out-o -the-box.
More detailed in ormation is given in the sections that ollow this "Getting Started" guide.
3.1 Components
LMI Technologies provides chroma+scan 3100, 3150, 3155, 3250, 3300, or 3301
sensors, a Master, and in ormation on cables to connect the Sensors, Master, and user

The above cables are available rom LMI and/or its suppliers. Also required is a
standard CAT5e Gigabit Ethernet cable (RJ45 connectors) to connect the FireSync
Station to the host computer.
3.1.4 Power Supply
The user must provide a suitable +48 VDC power supply or the system. I the system
employs a Station 1000, a separate +12 VDC supply will also be required. The output
from these power supplies must be isolated from AC ground.
LMI Technologies recommends the use o Phoenix Contact, QUINT series 48V DC
power supplies or the Master and sensor power. The current rating o the power supply
should be equal to the number o sensors connected to Master. For example, it is

18
recommended that a 16 sensor system uses a +48V power supply capable o delivering
16A.
For older systems using +12VDC Station hardware, LMI Technologies recommends the
use o a Lambda DSP60-12 power supply.
Both the Phoenix QUINT series and the Lambda power supplies are DIN rail mounted
devices that can be connected in parallel to increase the overall available power.

Order number: 2938248
+12 VDC
Model: DSP60-12
Order number: 285-1233-ND
3.1.5 Host Computer
The user must provide a suitable host computer. This must be equipped with a Gigabit
Ethernet port to communicate with the FireSync Station. The Client Inter ace to the
Station is OS independent. However, Windows XP is required on this computer in order
to install and run our FireSync Client demonstration application.
3.2 Connections
3.2.1 Sensors to Master
Please re er to the FireSync Networ User Manual or complete details on connecting
the sensors to the FireSync Master and Station.
3.2.2 Station to Host Computer
A standard CAT5e Gigabit Ethernet cable (RJ45 connectors) is used to connect the
FireSync Station, via the RJ45 connector "OUT", to a Gigabit Ethernet port on the host
computer. I two or more Stations are required in the system, this connection can be
made to a single host computer via separate Gigabit Ethernet cards, via a Gigabit
Ethernet switch, or via multiple processing stations.
3.2.3 Power Supply to Master/Station
The +48 VDC power supply is wired to the Phoenix connectors on the Master, Station*
and Slave (i a Slave is required). Re er to the FireSync Networ User Manual or
details.
*A separate +12 VDC power supply will be required to power up any Station 1000s in
the system.
3.2.4 Safety Interlock
The Sa ety Interlock signal allows the user to turn on and o all light sources in the
sensors without disrupting power to the system. I the sensor is “sa ety-enabled”, the

19
laser sa ety control signal must be provided at the Master and at all Slaves or the
sensors to properly unction. Please re er to the FireSync Networ User Manual or the
Sa ety Interlock connection requirements.
3.3 FireSync Client (Basic)
FireSync Client is a so tware application that can be used to set up, demonstrate, or
diagnose problems with a chroma+scan 3xxx system. The ollowing sections describe
how to use FireSync Client to connect to a system and veri y that all connected devices
are unctioning normally. For a detailed description o the FireSync Client application,
see the section entitled FireSync Client (Complete) in the Software chapter o this
manual.
3.3.1 Installation
The FireSync Client application is available or Windows XP, and can be downloaded
rom the LMI Technologies support website. To begin, download the so tware and install
it on a suitable client machine. The client machine should have an Ethernet adaptor that
can be con igured or a static IP address and that supports 1000 Mb/s operation.
A FireSync Station typically ships with the address 192.168.1.10, though this may vary
by request. Set the client machine to an available address on the same subnet (e.g.
192.168.1.9) and then connect a suitable Ethernet cable rom the client machine to the
FireSync Station’s OUT port.
I you are using multiple FireSync Stations, you may need to connect to each Station
individually in order to assign each Station unique IP addresses (both public and
private), using the Set IP command rom the Server menu. A ter each Station has been
assigned a unique address, you can reconnect to all stations simultaneously.

20
3.3.2 Connection
A ter starting FireSync Client, use the lightning (le t-most) icon in the toolbar to display
the Connect... dialog. To connect to a single server, enter the IP address o the server
to which you wish to connect, and then click OK.
To connect to multiple servers simultaneously, click the Advanced… button, add the IP
addresses o the servers, and then click OK.
