Preface
Audience
This manual should be read by all personnel who install or operate SR AOM series lasers.
Important!
Read this manual carefully before operating the laser for the first time. Pay special attention to
the Safety chapter.
The SR AOM series is designed and sold for use in Original Equipment Manufacturer (OEM) systems and
is not to be used as a stand-alone laser. The OEM is responsible for compliance with all applicable safety
regulations.

• Luxinar part number 906-0202-99; Chiller water temperature tables
How to use this manual
The following conventions are used in this manual.
Admonitions
The use of controls, replacement parts, adjustments, or procedures other than those specified within
this manual may result in exposure to any of these hazards.
• Laser hazards
• Electrical hazards
• Environmental hazards
• Mechanical hazards.
The degree of seriousness of the hazard is indicated by the use of the following signal words:
DANGER
Indicates an imminent hazard which, if not avoided, is extremely likely to result in death or serious
injury.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury. It is also used to alert the user against unsafe working practices and potential damage to the
equipment.
Connector labels and signal names

1. Safety
1.1. General safety information
It is strongly recommended that any personnel who are involved with the installation, operation or
maintenance of this laser equipment should first read and fully understand the contents of this manual.
If there are any questions or doubts on any of the safety aspects of the equipment, then do not hesitate
to contact your nearest Luxinar Aftersales office or distributor for advice before proceeding.
The installation, operation, maintenance and repair of this laser equipment must only be carried out by
Luxinar service personnel or trained staff who have received correct instruction concerning the hazards
associated with this particular equipment.
Take extensive precautions to prevent exposure of laser radiation to the eye and skin from either direct
or reflected laser beams. In addition, precautions must be taken to prevent the hazards of fire, electrical
injury and pollution.
The information and precautions given in this chapter are extensive but may not be complete. The
system integrator is advised to supplement this information with information regarding current
technical and regulatory advances as they become available.
Important!
All safety critical instructions contained within this document are framed with a border and
identified by CAUTION, WARNING or DANGER depending on the severity of the risk involved. In
addition, the safety symbol indicates that care should be taken when working with or on the
laser equipment.
Strict compliance with the safety precautions set out and referred to in this manual and extreme care in
use are essential to minimise the chance of accidental damage to the equipment or personal injury.
Luxinar does not accept liability for any damage or injury howsoever caused or arising.
The symbol given below is also used on the equipment and indicates that the user should refer to the
OEM equipment operator’s manual for more information on the safe operation or installation of the
equipment.
1.2. Laser radiation safety standards
The European standard for the Radiation Safety of Laser Products is EN60825-1:2014. Luxinar lasers are
designated as Class 4 and as such, the user should appoint a Laser Safety Officer who should be familiar
with the content of EN60825-1:2014. Special attention is drawn to EN60825-1:2014 Part 14: User’s
guide. This laser product is designated solely for use as a component laser and therefore does not meet
all the requirements of EN60825-1:2014.
The United States guidelines for the manufacture and subsequent sale of laser equipment are governed
by the Centre for Devices and Radiological Health (CDRH). The laser safety requirements are covered in
sub-chapter J of the Radiation Standards, 21 CFR. This laser product is designated solely for use as a
component laser and therefore does not meet all the requirements of 21 CFR 1040.10.
It is the responsibility of the buyer of these components to ensure that the final system sold to an end
user complies with all the relevant laser safety requirements prior to the sale of that system. The buyer
is also required to provide a system report filing to CDRH before the system is shipped to an end user.
The labels shown in section 1.12 are fitted to the equipment in the locations specified and must not be
removed or defaced. Immediately replace any missing labels.
The average output power, peak power per pulse, the pulsed frequency, the wavelength of the radiation
and other specifications for the laser(s) covered by this manual can be found in section 2.3.
Luxinar laser control systems are designed in compliance with BS EN ISO 13849-1:2015 “Safety
requirements and guidance on the principles of design and integration of safety-related parts of control
systems”. The control system for the complete machine must also comply with this standard in order
906-0227-00 REV 1 1 1. Safety

that the machine is capable of operating as a Class 1 laser machine as defined in the EN60825-1 or 21
CFR 1040.10 laser safety standards.
SR AOM series lasers are provided as components to be integrated into OEM systems therefore overall
responsibility for compliance resides with the OEM manufacturer/installer of the final machine.
DANGER
Risk of injury to eyes and exposed skin
This is a Class 4 (Class IV) laser product. All precautions relevant to this class of laser product
should be strictly observed. Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure. Strict compliance with
the safety precautions set out and referred to in this manual and extreme care in use are
essential to minimise the chance of accidental damage to the equipment or personal injury.
Luxinar does not accept liability for any damage or injury howsoever caused or arising.
1.3. Equipment safety standards
In addition to the laser safety standards detailed in section 1.2, Luxinar laser systems are manufactured
to the following additional safety standards:
1. 2014/35/EU Low voltage Directive and EN 61010-1:2010+A1:2109. This equipment is designed for
indoor use only, pollution degree 2 and overvoltage category II.
2. 2014/30/EU — Electro-Magnetic Compatibility Directive
3. EN61000-6-2:2019 — EMC immunity for industrial environments
4. EN 55011-2016+A11:2020 — EMC emissions for equipment that include RF generators Group 2
Class A.
5. BS EN ISO 13849-1:2015 — Safety requirements and guidance on the principles of design and
integration of safety-related parts of control systems.
1.4. Intended use for the laser equipment
The laser equipment described in this document is intended to be used for processing materials in an
industrial environment. The laser is a source of radiation and as such forms part of a laser processing
system. The intended use of the laser is therefore determined by the type of laser system into which it is
incorporated (e.g. cutting, welding, marking, surface working) as well as by the manufacturer’s
instructions.
This laser equipment is intended to be integrated into large scale industrial tools or equipment defined
to consist of a combination of equipment, systems or products, each of which is manufactured and
intended to be used only in fixed industrial applications.
Large scale industrial tools are currently based on the following criteria:
• Consist of a combination of equipment, systems, products and/or components (therefore not a
single discrete tool such as a small or medium scale lathe, milling machine or pillar drill).
• Be required to be fixed to operate safely or within specification.
• Be of large scale.
• Require professional installation.
• Only to be used in an industrial environment.
• Be built to perform a specific task.
