• The built-in +15 VDC, 250 mA voltage output on Pin 2, DC Out, was accidentally shorted to
ground.
Possible Causes:
• If Pin 2, DC Out, is shorted to ground, the OEM v30 laser will shut down, but restarts
automatically when the short-circuit is removed.
Beam delivery optics
Symptom:
• The laser appears to lose power over time; laser output power must be increased to maintain
previous performance.
Possible Causes:
• Beam delivery optics are coated by vapor residue or debris.
Shut down the laser and carefully inspect each optic in the beam delivery path, including the laser’s
output coupler. Remember that optics are fragile and must be handled carefully. If the optic requires
cleaning, then refer to Maintenance for cleaning instructions. Use only recommended cleaning materials
to prevent scratching delicate optical surfaces.
If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high power
density of Firestar lasers, pits or debris on the lens may absorb enough energy from the focused beam
to crack the lens. If this happens, other optics in the beam path may be contaminated or damaged as
well.
Caution: Possible Equipment Damage
If you operate your laser or marking head in a dirty or dusty environment, contact NOVANTA about
the risks of doing so and precautions you can take to increase the longevity of your laser, marking
head and associated optical components
Danger: Serious Personal Injury
Ensure that DC power to the laser is turned off and locked out before inspecting optical components
in the beam path. Invisible CO2 laser radiation is emitted through the aperture. Corneal damage or
blindness may result from exposure to laser radiation.
