Safety 1 - 7
1. Do not remove the covers from the laser or its power supplies.
Removing these covers will expose voltages. In addition,
removing internal covers from around the laser or its correction
optics may allow leakage of laser light.
2. The area around the laser and its power supplies should be kept
dry.
3. Never operate the laser if there is any sign of leakage of water
from the system. Call the local Service Department.
4. Do not operate the laser if the mains cable is faulty or frayed.
5. The laser should undergo routine inspection and maintenance
according to ROFIN’s recommendations, as detailed in section 4
of this manual.
1.9 Safety Precautions
The ROFIN SC range of lasers incorporate various safety features as
required by EN60825 and CDRH radiation safety standards. The end user
will be required to utilise these functions within a full system installation to
meet these safety standards. These are as follows:
i) Safety Interlocks
No sections of the laser’s protective housing can be easily opened
without special tools. The CO
2
laser has no user serviceable parts
within the protective housing and does not contain any access panel
with Safety Interlocks within the meaning of EN60825 section 4.3.
ii) Laser Radiation Emission Warning Lamp
It is to be assumed that for the purpose of safety, that if the laser
emission lamp is illuminated, then laser radiation output from the
system is possible. The laser emission lamp is located on the rear
flange of the laser housing.
If the emission lamp fails during operation of the system, then an
emission lamp failure signal is provided for the systems integrator.
See section 3 of this manual for details of the signal.
iii) Safety Shutter
A solenoid driven Safety Shutter is incorporated into all ROFIN SC
systems. This allows the user to block or dump the laser output beam
with a reflective mechanical blade. There are also two position
sensors for the Shutter Open and Shutter Closed positions for safety
monitoring.
For details of the inputs and outputs required to operate the Shutter
and monitor its position, see section 3 of this manual.
1.10 Additional Recommended Safety Precautions
In addition, the end user will also be required to add the following functions
within a full system installation to meet the CDRH, EN60825, Machinery
Directive EN89/392/EEC (EN60204 and EN292) and NFPA 79 safety
standards:
