Initial start-up
Without a UC-2000 Controller
If you are not using a UC-2000 to control the laser, follow the steps below to verify laser operation. Al-
though a tickle signal is not required, you will need to provide PWM Command signals to Firestar’s
User
I/O
connector. Refer to
User I/O connections
in the Technical Reference chapter for connector pinouts and
see
Controlling laser power
in the Technical Reference chapter for Command signal descriptions.
Danger
serious
personal
injury
This Class IV laser product emits
invisible
infrared laser radiation in
the 10.6 µm CO
2
wavelength band. Since direct or diffuse laser radia-
tion can inflict severe corneal injuries, always wear eye protection
when in the same area as an exposed laser beam. Do not allow the
laser beam to contact a person. This product emits an invisible laser
beam that is capable of seriously burning human tissue.
Always be aware of the beam’s path and always use a beam block
while testing.
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 24 inches (61 cm) from the laser aperture to prevent the beam from traveling
beyond the work area.
4
On water-cooled systems, turn on the chiller (set between 18–22 °C) and verify that it is delivering
1.0–2.0 GPM (ti60) or 1.5–2.0 GPM (ti100) at less than 60 PSI of pressure.
Caution
possible
equipment
damage
Inlet cooling water temperature must always be maintained above the
dew point temperature to prevent condensation and water damage to
your Firestar laser.
5
Connect the output of your PWM Controller to
PWM Input
(Pin 9) on the laser’s
User I/O
connec-
tor and connect the ground or return of the Controller to
PWM Return
(Pin 1).
6
Set your PWM Controller to a frequency of 5 kHz @ +5 VDC and ensure that the Controller’s duty
cycle is set to zero percent output (0.0%).
7
Verify that the laser’s
Keyswitch
(if equipped) is in the OFF position.
