Protecting Yourself During Procedures
Laser Safety During Servicing
WARNING!
When an enclosed, Class 1 system is in service (manual override) mode, it can emit
hazardous laser radiation.
Only specifically trained service personnel may operate the system in service mode,
and only they should have access to the key for the Manual Override switch.
When working on the system in service mode, service personnel must wear protective
eyewear or a face shield, long sleeves, and long pants. We also recommend using UV-
blocking sunscreen to protect against exposure to scattered UV radiation.
Beam Delivery System
The beam delivery system (BDS) is a light-tight assembly of tubes, optics, and other
components that routes the beam safely from the laser output to the objective lens
above the processing site.
The BDS is not interlocked, however, so the laser can continue to operate if the BDS is
breached. In this case the process enclosure still protects personnel during normal
operation or routine maintenance.
Normal and Service Modes
WARNING!
When the system is in service (manual override) mode, it can expose you to hazardous
laser radiation.
The keyed Manual Override switch switches between normal and service (manual
override) modes. When the system is in service mode:
❑
The safety interlocks on the enclosure doors no longer work. This allows the
system to operate in Class 4 mode for laser maintenance or optics adjustments.
❑
The IPG Photonics software no longer controls the beam stop. Instead, the manual
Beam Stop switch on the control panel controls it.
❑
The remote interlock circuit is enabled. This lets you wire an external switch so
that, for example, opening the door to the room turns off the laser.
To protect personnel when the system is in service mode, use the connections
available through the customer interface connector to install a laser radiation warning
light at the entrance to the laser room and a safety interlock switch on the laser room
door.
Ventilation and Debris Control
The workstation uses several kinds of ventilation to keep the work environment safe:
❑
Process enclosure ventilation to remove excess heat and to keep vapors and
particulates from escaping into the surrounding area.
❑
Suction to remove vapors, particles, and hazardous debris from the part
processing location.
❑
Laser enclosure ventilation (for systems with external lasers) to remove heat and
toxic gas.
For more information, refer to "Ventilation and Debris Control" Chapter 10.
