Initial start-up
The Initial start-up section includes subsections:
•
With a UC-2000 Controller
•
Without a UC-2000 Controller
With a UC-2000 Controller
Before your laser is put into service for the first time, its functionality should be verified. Follow this
procedure to verify the laser system is operating at optimum performance. For this procedure, use the
UC-2000 as a stand-alone controller; do not attempt to control the laser or UC-2000 externally.
Note: When performing the initial start-up sequence, you must first connect the Quick Start Plug or you
must provide the required Remote Interlock and Shutter Open Request signals to the User I/O connector.
See User I/O connections in the Technical Reference chapter for User I/O pinouts and signal descriptions.
Starting auxiliary equipment
1 Ensure that all personnel in the area are wearing protective eyewear.
2 Remove the red self-adhesive aperture seal from the laser faceplate.
3 Place a beam block 61 cm (24 in) from the laser aperture to prevent the beam from traveling
beyond the work area.
4 Turn on the chiller and set the temperature setpoint between 18 °C–22 °C. Verify that the chiller is
delivering the recommended flow rate for your laser at less than 414 kPa (60 PSI) of pressure.
Examine all cooling connections carefully and ensure that they do not leak.
5 Start purge gas flow at a rate of 0.85–1.7 m
3
/hr (30–60 SCFH, Standard Cubic Feet per Hour) at a
pressure not to exceed 34.5 kPa (5 PSI). If a flowmeter is not available, set a purge pressure
between 13.8–34.5 kPa (2–5 PSI).
Important Note: If you have not yet operated your UC-2000 Universal Laser Controller, refer to
the UC-2000 Laser Controller Operator’s Manual and quick start guide for setup and operation
instructions before continuing.
6 Set the UC-2000 to MANUAL mode, and then set the PWM Adj Knob to provide zero percent
output (0.0%). The UC-2000’s Lase indicator should be Off.
7 Verify that the laser’s Keyswitch (if equipped) is in the OFF/RESET position.
8 Turn on the +96 VDC power supply.
If the factory-wired Quick Start Plug is installed, the Remote Interlock indicator will illuminate green and
the Shutter indicator will illuminate blue—if the manual Shutter Switch is Open. The Temp indicator will
illuminate green if laser temperature is within safe operating limits.
