Initial start-up
Without a UC-2000 Controller
If you have chosen not to use a UC-2000 to control the laser, follow the procedure below to verify the
laser’s functionality. You will need to provide a tickle signal and a pulse width modulated (PWM)
Command signal to the laser’s CTRL input connector. Refer to Controlling laser power in the “Technical
Reference” section for tickle and PWM Command signal descriptions.
Caution
possible
equipment
damage
Series 48 lasers MUST be provided with a pre-ionizing “tickle”
signal during standby or laser “low” periods. This signal is automati-
cally provided by SYNRAD’s UC-2000 Universal Laser Controller
or FH Series marking head.
A tickle signal keeps the plasma ionized during laser “low” periods
and facilitates plasma breakdown and pulse-to-pulse fidelity.
Damage to or malfunction of the laser may occur if this, or equiva-
lent drive signals are not provided.
Note: When performing the initial start-up sequence, check that the factory-installed DB9 jumper
plug is installed. If not, you must provide the required Remote Interlock and Remote Key-
switch signals to the DB9 Connector. See DB9 connections in the “Getting Started” section for
DB9 pinouts and signal descriptions.
Starting auxiliary equipment
1
Ensure that all personnel in the area are wearing protective eyewear.
2
Place a beam block 24 inches from the laser aperture to prevent the beam from traveling beyond
the work area.
3
On water-cooled systems, turn on the chiller (set between 18 °C to 22 °C) and verify it is deliver-
ing 0.5 GPM (48-1), 0.8 GPM (48-2), or 1.5 GPM (48-5) at less than 60 psi of pressure. Examine
all cooling connections carefully and verify that they do not leak.
Danger
serious
personal
injury
This product emits invisible infrared laser radiation at the 10.6 µm
CO
2
wavelength. Since direct or diffuse laser radiation 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.
