1—16 PS288 Owner’s Manual
To avoid possible personal injury or damage to the equipment, please
observe the following practices:
) Do not use the PS288 for any purpose other than its intended use.
) Do not operate the system if the safety shields are not in their normal
operating positions.
) Do not operate the system when any of the outer sheet metal panels are
removed.
) Only qualified personnel trained by Data I/O to service and maintain
the PS288 (including laser safety training) should install, maintain,
repair, or troubleshoot the system.
) Do not operate a system while servicing, replacing, or adjusting any
component unless directed to do so in this manual. Make sure that the
system is properly shut down before performing any of these opera-
tions.
) Do not operate the PS288 unless you have been thoroughly trained and
have read and understand the instructions in this manual, particularly
those that describe the system’s safety features.
) Disconnect the external air line before servicing pneumatic parts.
) Do not place any part of your body near or in the direct path of moving
parts.
) Do not disable or attempt to defeat any of the safety features of this
system. Serious personal injury and/or equipment damage can occur if
any safety systems on the PS288 are disabled. If you suspect that a
safety feature of the system is damaged or malfunctioning, stop using
the PS288 immediately and contact your local Data I/O Support office.
) Read and follow the laser vacuum filter disposal requirements
described later in this section. Always dispose of any other hazardous
or residual by-products of the production process in accordance with
governing laws and regulations.
) Use extra caution when using the tape input/output modules or device
labeling option. The PS288 safety shields do not cover or fully enclose
these modules. It is possible that hands, body parts, or loose clothing
can get caught or pinched in these mechanisms.
Laser Safety
The laser marking system, located in the Option Bay attached to the PS288,
has been designed in accordance with the following safety guidelines:
• Operates as a Class 1 laser (CDRH classification).
• Fume extractor traps marking fumes and other by-products of the laser
marking operation.
• System designed to comply with OSHA guarding standards.
• Integrated safety interlocks prevent the laser from firing while any
interlock is activated.
• Refer to and follow laser and safety precautions in ANSI X136.1-1993,
American National Standard for the Safe Use of Lasers. Procedures
listed under the Standard include: appointment of a Laser Safety
Officer, operation of the product in an area of limited access by trained
personnel, servicing of the equipment only by trained and authorized
personnel, and posting of signs warning of potential hazards.

WARNING: Blindness hazard! Always wear eye protection when
the laser safety shields are open, such as during service. Direct or
diffuse laser radiation can damage eyes. Goggles must block
10.6 µm laser radiation. Goggles protect against scattered energy
but not against direct viewing of the laser beam or reflections
from metallic surfaces.
WARNING: Serious burn hazard! Direct or diffuse laser radia-
tion can cause serious burns. Keep hands and other parts of the
body out of the path of the laser bean when servicing.
WARNING: Toxic fume hazard! Laser marking generates vapors,
fumes, and particles that may be noxious, toxic, or even fatal.
Follow maintenance procedures on the fume extractor. Use
proper ventilation.

Laser Safety Interlocks
The Option Bay has five laser safety interlocks that prevent the laser from
firing when any safety shield on the Option Bay is removed. To physically
enable the laser, all laser safety interlocks must form a complete electrical
circuit to the laser’s safety inhibit input. When activated, (i.e., when any
safety shield is removed) the safety interlock disables the laser’s safety
inhibit circuit. Activation of the safety interlock prevents (via hardware in
the laser itself) the laser from firing. A laser safety interlock is shown in Fig-
ure .
Figure 1-12—Laser safety interlock
The five laser safety interlocks are located:
1. Behind the removable safety shield on the front (toward the PS288) of
the Option Bay
2. Behind the removable safety shield on the upper left side of the Option
Bay
3. Behind the removable safety shield on the top of the Option Bay
4. Behind the removable safety shield on the upper right side of the
Option Bay
5. Behind the removable safety shield on the lower left side of the Option
Bay
