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 classification depending on model.
Class 2/ll and 3R/llla sensors are referred to as “products” indicating that they fully
comply with the standards relating to laser products specified in IEC 60825-1 and U.S.
FDA CFR Title 21 Part 1040 except for deviations pursuant to Laser Notice No. 50,
dated July 26, 2001.
Class 3B/lllb sensors are sold only to qualified OEM’s as “components” for incorporation
into their own equipment. The sensors do not incorporate safety items which the OEM is
required to provide in their own equipment (e.g. remote interlocks, key control). As such
these sensors do not fully comply with the standards relating to laser products specified
in IEC 60825-1 and FDA CFR Title 21 Part 1040.
Caution! Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.

1. International Standard IEC 60825-1 (2001-08) Consolidated edition, Safety of
laser products –Part 1: Equipment classification, requirements and user’s guide
2. Technical Report TR 60825-10, safety of laser products –Part 10. Application
guidelines and explanatory notes to IEC 60825-1
3. Laser Notice No. 50, FDA and CDRH http://www.fda.gov/cdrh/rad-health.html
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 foreseeable conditions of
operation, provided that any exposure can
be terminated by the blink reflex (assumed
to take 0.25 sec). Because classification
assumes the blink reflex, the wavelength of
light must be in the visible range (400 nm to
700 nm). The Maximum Permissible
Exposure (MPE) for visible radiation for 0.25
second is 25 Watt per square meter, which
is equivalent to 1 mW entering an aperture
of 7 mm diameter (the assumed size of 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 for
3B/lllb lasers. Fewer manufacturing
requirements and control measures for
users apply than for 3B/lllb lasers.
Class 3B/lllb laser components:
Class 3B/lllb components are unsafe for eye
exposure. Usually only ocular protection
would be required. Diffuse reflections are
safe if viewed for less than 10 seconds.
Labels reprinted here are
examples relevant to the laser
classes. For detailed
specifications observe the label
on your laser sensor

LMI Class 3B/lllb laser components do not incorporate the safety items indicated by
asterisks ** in the table above. These items must be added and completed by the OEM
in the system design.
1.2.3 Class 3B/lllb OEM Responsibilities
LMI Technologies has filed reports with the FDA to assist the OEM in achieving
certification of their laser products. The OEM can reference these reports by an
accession number that will be provided upon request.

9
Detailed descriptions of the safety 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 of any remote switches must prevent power from being supplied to any
lasers.
Key Control
A key operated master control to the lasers that prevents any power from 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 from the lock while in the ON
position.
Power-On Delays
A delay circuit is required that illuminates warning indicators for a short period of time
prior to supplying power to the lasers.
Beam Attenuators
A permanently attached method of 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. If distance (>2 m between
sensor and controls) or mounting of sensors intervenes with observation of 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 of the sensor such that they will be
readily observed. Examples of 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
manufactured by LMI Technologies requires certification by the FDA.
It is the responsibility of the OEM to achieve and maintain this certification.
OEM’s are advised to obtain the information booklet Regulations for the Administration
and Enforcement of the Radiation Control for Health and Safety Act of 1968: HHS
Publication FDA 88-8035.
This publication, containing the full details of laser safety requirements, can be obtained
directly from the FDA, or downloaded from their website at http://www.fda.gov/cdrh.

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 from the mounting hardware to the sensor housing. For sensors
with tapped hole mounts, conductive hardware must to be used between the sensor and
the frame. This must be checked with a multi-meter by ensuring electrical continuity
between the frame and the connector housing on the sensor. It is imperative that the
scan frame 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 of 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 of shielded cables in all environments to ensure
isolation from 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
for building cordset.
2.1.3 Power Supply
The user must provide a suitable +48VDC power supply for the system capable of
handling an infinite capacitive load. These power supplies must be isolated such that DC
ground is NOT tied to AC ground. The power supply should be of a suitable capacity for
the size of the system.
LMI Technologies recommends the Phoenix Contact QUINT series of power supplies.

12
2.1.4 Uninterruptible Power Supply (UPS)
To maximize the life of the sensor, LMI Technologies recommends the use of an on-line
double-conversion UPS whenever the quality of the electrical supply to the system is
poor. This includes but is not limited to when the electrical supply:
•contains high frequency noise (due to other electronics, electric motors or other
factors)
•is prone to “brown-out” conditions or large voltage fluctuations
•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 flammable 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 for 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 front of the sensor should be kept
clean and clear of debris.
Use dry, clean air to remove dust or other dirt particles. If dirt remains, clean the
windows carefully with a soft, lint-free cloth using an ammonia based cleaner. Ensure
that no residue is left on the windows after cleaning.
2.4 Laser Lifetime
LMI Technologies uses semiconductor lasers in their 3D measurement sensors. To
maximize the lifespan of the sensor it is recommended to turn off the laser by stopping
the sensor whenever it is not in use. Another method for maximizing laser lifetime is to
enable the laser watchdog feature which automatically turns off lasers in a sensor when
there is no conveyor chain movement (see Section 7.2.4.1 for details).

Section 3
3 Getting Started
Warning! chroma+scan 3x00 sensors are class 3B/IIIb components. Please read
Section 1: Laser Safety above, and institute the necessary safety precautions before
turning these sensors on.
This section provides a brief introduction to the chroma+scan 3x00. It identifies the
components supplied by LMI Technologies, and the additional components required to
get a basic system up and running. This is followed by instructions on how to connect
these components together, and how to install and run our client software to acquire
basic profile data to ensure sensor operation out-of-the-box.
More detailed information is given in the sections that follow this "Getting Started" guide.
3.1 Components
LMI Technologies provides chroma+scan 3155, 3250, or 3350 sensors, a Master and
information on cables to connect the Sensors, Master, and user provided equipment.
The user must provide a power supply, station computer, client computer, a Gigabit
Ethernet switch, and cables to connect the sensors and the Master.

15
3.1.2 Master
FireSync Master 1200 or 2400
Generation 2
3.1.3 Cables
Network Cordset
The above cable is available from LMI and/or its suppliers. Also required are standard
CAT5e Gigabit Ethernet cables (RJ45 connectors) to connect the user Station PC to the
client computer and the Sensor network GigE switch.
Note: Cable lengths for cs3x00 systems should not exceed 70m.
3.1.4 Power Supply
The user must provide a suitable +48 VDC power supply for the system. The output
from all power supplies must be isolated from AC ground.
LMI Technologies recommends the use of Phoenix Contact, QUINT series 48V DC
power supplies for the Master and sensor power. The current rating of the power supply
should be equal to the number of sensors connected to Master. For example, it is

16
recommended that a 16 sensor system uses a +48V power supply capable of delivering
16A.
The Phoenix QUINT series power supplies are DIN rail mounted devices that can be
connected in parallel to increase the overall available power.
+48 VDC
Model: QUINT-PS-100-240AC/48DC/10
Order number: 2938248
3.1.5 Station Computer
The Station is a user-supplied PC used to process data from the sensors and to
interface with the client PC. The software that runs on the station performs three key
roles:
•Data processing through the kServer application.
•Management of the kServer process through the kManagementServer
application.
•Diagnostic logging of the system through the kDashboard application.
Multiple stations can be used in a system. However, for multiple station systems, the
firmware and software upgrade package must be run individually per station.
Requirements
•Minimum 2x gigabit (1 Gbps) Ethernet ports (Recommended: Intel PRO/1000
Network Adaptor or equivalent, x2)
•Pentium 4, Pentium D, or Pentium Core Duo at 2.0 GHz or above
•Minimum 2 GB of RAM
•Minimum 10 GB of Hard Disk Space
•Windows XP SP3 32-bit or Embedded XP, Windows 7 Professional 32-bit or 64-
bit*
•Any firewall software must be disabled
•The network card driver should be updated to the latest available version
•USB 2.0 ports (recommended)
*While Windows XP is technically supported, Embedded XP is strongly
recommended. Windows XP lacks the capabily to support a hard power-down
situation and it will be the responsibility of the user to initiate a proper shutdown
process every time power disconnected.
IN Port
The IN port is a Gigabit Ethernet link to a Master. It communicates on the sensor
(Private) network.
The IN port IP address should always be on the 90.X.X.X subnet. This address can be
changed by sending a “Set Private IP” command to the Station, which is done, typically,
to support multiple station configurations. The valid addresses are 90.0.0.1 to 90.0.0.5.
The default IP is 90.0.0.1. A typical configuration is:

17
•IP address : 90.0.0.1
•Subnet Mask 255.0.0.0
Out Port
The OUT port is a gigabit Ethernet link to the client (Public) network. It is the gateway
through which the user communicates with the sensor network.
The OUT port can be set to any IP address except addresses belonging to the 90.X.X.X
subnet. A typical configuration is:
•IP address : 192.168.1.10
•Subnet Mask 255.255.255.
Section 7.1 describes the steps of setting up a PC to be a FireSync Station node.
3.1.6 Client Computer
The user must provide a suitable client computer. This must be equipped with a Gigabit
Ethernet port to communicate with the FireSync Station. The client Interface to the
Station is OS independent. However, Windows XP or Windows 7 (32-bit/64-bit) is
required on this computer in order to install and run LMI’s FireSync Client demonstration
application.
3.1.7 Gigabit Ethernet Switch
The user must provide a suitable Gigabit Ethernet Switch for the Sensor network. The
Gigabit Ethernet switch is connected to each Sensor through the Ethernet RJ45
connection through the Sensor’s network cordset. The Gigabit Ethernet Switch is
connected to the Master’s Link port with a standard CAT5e Gigabit Ethernet cable (RJ45
connectors).
3.2 Connections
3.2.1 Sensors to Master
Please refer to the FireSync Network User Manual for complete details on connecting
the sensors to the FireSync Master and Station.
3.2.2 Station to Client Computer
A standard CAT5e Gigabit Ethernet cable (RJ45 connectors) is used to connect the
Station PC, via the RJ45 connector "OUT", to a Gigabit Ethernet port on the client
computer. If two or more Station PCs are required in the system, this connection can be
made to a single client computer via separate Gigabit Ethernet cards, via a Gigabit
Ethernet switch, or via multiple processing stations.
The station output port is used to send data to the client (port mapping is established
during the FireSync Station Software installation process, described in Section 7.1).

18
The client PC’s IP address will have to be configured to the same subnet as the station’s
OUT port:
•In the Windows control panel, select “Network Connections”
•Double-click on the name of the connection being used
•Click “Properties”, and double-click on “Internet Protocol (TCP/IP)”. This window
will show up:
•Select “Use the following IP address”, and input the Subnet mask shown above.
The IP entered must be on the same subnet as the station’s (the IP address
shown above is appropriate for connecting to a station with the default IP
address of 192.168.1.10). Click OK.
•Click OK on the Connection properties window. The client PC has now been
configured to connect to a FireSync Station.
After this procedure is complete, the station can be connected to via FireSync Client
(See Section 3.3.2).
3.2.3 Power Supply to Master/Station
The +48 VDC power supply is wired to the Phoenix connectors on the Master. Refer to
the FireSync Network User Manual for details.
3.2.4 Safety Interlock
The Safety Interlock signal allows the user to turn on and off all light sources in the
sensors without disrupting power to the system. If the sensor is “safety-enabled”, the
laser safety control signal must be provided at the Master and at all Slaves for the
sensors to properly function. Please refer to the FireSync Network User Manual for the
Safety Interlock connection requirements.

19
3.2.5 Connection Guidelines
•The maximum sensor load per station varies with station performance. Station CPU
usage should be monitored to ensure any core does not exceed 80% usage.
•Sensors can be grouped into different sensor networks for multi-station systems.
Each station can only have a single network connection to the sensor network.
However, each station can have multiple network connections to the client network
which allows different client PCs to process data separately. This is accomplished
through the use of two NICs in the station, each on a different subnet with a different
static IP. Different channels can then be set up to direct data to separate client PCs.
3.3 FireSync Client (Basic)
FireSync Client is a software application that can be used to set up, demonstrate, or
diagnose problems with a chroma+scan 3x00 system. The following sections describe
how to use FireSync Client to connect to a system and verify that all connected devices
are functioning normally. For a detailed description of the FireSync Client application,
see the section entitled FireSync Client (Complete) in the Software chapter of this
manual.
3.3.1 Installation
The FireSync Client application is available for Windows, and can be downloaded from
the LMI Technologies support website. To begin, download the software and install it on
a suitable client machine. The client machine should have an Ethernet adaptor that can
be configured for a static IP address and that supports 1000 Mb/s operation.
The user provided Station PC is typically configured with the address 192.168.1.10, but
can be configured as required. 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 from the
client machine to the Station.
If 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 from the Server menu. After each Station has been
assigned a unique address, you can reconnect to all stations simultaneously.

20
3.3.2 Connection
After starting FireSync Client, use the Connect (left-most) icon in the toolbar to display
the Connect... dialog. To connect to a single server, enter the IP address of 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 of the servers, and then click OK.
