Universal Laser Systems X-600 Safety, Installation, Operation, And Basic Maintenance Manual page 70

NOTE: Air will always be flowing through the system as long as the compressed air source is
turned ON. We recommend installing a shut off valve in between your compressed air supply
and the laser system.
Before you run your material, we suggest that you adjust your air and/or gas flow. To do this, you
must first turn on your compressed air source so that there is flow through the system. Now, either
turn the laser system ON or leave it OFF.
With the top door of the laser system open, pass a piece of paper underneath the cone and use it to
note the amount of air flowing through the cone and against the paper or place your finger underneath
the cone to try to feel the pressure.
As a safety precaution, you should place your finger underneath the cone ONLY
when power to the system has been turned OFF. If the power is ON, you should
use the paper method.
Turn the adjustment valve knob clockwise or counterclockwise until either the desired airflow or PSI
reading on the gauge is achieved.
adjustments increase flow.
Computer Controlled Air Assist
The control box (1) (represented by the dotted lines)
directs the compressed air source to the optics
protection path and also to the cone. The optics
protection path is a direct path from the entry point
of the compressed air source (2) to the beam
window (3), the #2 mirror (4), and #3 mirror (5). The
air supply for the cone comes from either the HIGH
(6) or LOW (7) solenoid valves, through the HIGH
(8) or LOW (9) pressure adjustment valves, through
the pressure gauge (10) and finally to the cone. The
cone path protects the focus lens (11) and provides
a downward flow directly into the beam path at the
focus point. You choose which solenoid valve (6 or
7) to open through the laser systems printer driver.
The gauge (10) will ONLY show a reading when
either the HIGH (6) or LOW (7) solenoid valve is
opened and air is flowing to the cone. If you choose
to use an inert gas to supply the cone, the supply
must go through the GAS coupling (12), through the
gas solenoid valve (13) and finally to the cone. The
GAS path bypasses the pressure adjustment valves and the gauge so it must be regulated externally.
Only one solenoid valve (6,7, or 13) can operate at one time.
As the diagram indicates, the optics protection path is neither regulated nor solenoid valve controlled.
If you are using your own compressor, the optics protection air will always be flowing regardless of
whether the laser system is running or not. You must install either a manual shut off valve (not
supplied) or an external electronic solenoid valve system (not supplied). If you purchased the Air
Compressor option the optics protection air will turn ON and OFF as the compressor turns ON and
OFF respectively.
