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.

Other publications

• Luxinar part number 906-0109-00; Serial interface specification
• 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

Connector labels and signal names are shown in bold serif font to aid identification.
For example; 

RF Enable
