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.

laser products – Part 1: Equipment classification, requirements and user’s guide

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.
Detailed descriptions of the safety items that must be added to the OEM design are
listed below:

8
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:

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.
