troubleshooting
Q: My projector’s aperture glass is cracked, broken
or missing. Can I continue using my projector?
A: Laser beams hitting glass splits will be scattered into
unwanted directions, creating a risk of damage to eyesight,
health or property. Broken or missing aperture glass enables
humidity, water, and dust inside the laser projector’s optical
compartment, which can cause permanent damage to the
system.
It is essential to replace the damaged or missing aperture
glass before using the laser projector.
Q: The housing of the projector is damaged. Can
I continue using my projector?
A: The projector must not be operated if the housing
is damaged to the level that it causes visible gaps between the
projector’s adjacent faces. The gaps enable humidity, water,
and dust inside the laser projector’s optical compartment,
which can cause permanent damage to the system.
There is also a risk of laser emission leaks from other
parts of the system, which contradicts the IEC 60825-1
safety standard. Damaged housing parts must be repaired
or replaced before operating the projector again.
Q: Projector’s eyebolt is bent, fractured or unscrewed.
Can I continue using my projector if it is installed using
the eyebolt as a safety mechanism? Or continue with the
installation?
A: No! The projector must not be used, lifted or hanged.
Never attempt to repair bent or fractured eyebolt. Replace
it with a new one with the same or higher load capacity.
Q: Is it OK that the cooling fans are not running during
operation?
A: Yes, it’s OK. Kvant projectors have built-in automatic
regulation of the fan speed. After powering up the
projector, all cooling fans will run at 100% speed for about
2 seconds. Then their speed is adjusted according to the
heatsink’s temperature.
Clubmax (without FB4):
if heatsink’s temperature is below 25°C (77°F), the fans are
turned off. Within the range of 25°C (77°K) to 55°C (131°F),
the fan speed increases with increasing temperature
of the heatsink, and over 55°C (131°F) they run at full
speed.
BeamBrush, Clubmax FB4, Atom and Spectrum series:
if heatsink’s temperature is below 15°C (59°F), the fans are
turned off or run at low speed. Within the range of 15°C
(59°K) to 33°C (91°F), the fan speed increases with increasing
temperature of the heatsink, and over 33°C (91°F) they run
at full speed.
Q: Is it OK if some fans are running at full speed and some
at low speed during the operation?
A: Yes, it is OK . Kvant Atom and Spectrum projectors use
multi-zone regulation of the fan speeds. Fans that cool
down warmer sections of the heatsink work at higher
speeds. The correct functionality of all fans can be checked
anytime by power cycling the projector. After powering
up the projector, all cooling fans will run at 100% speed for
about 2 seconds. Then their speed is adjusted according
to the heatsink’s temperature.
Q: Cooling fans generate a strange noise. Is that
a problem?
A: Strange noise is usually caused by an object stacked
in the fan’s propeller area. It can be a piece of confetti
or plastic or even a hardened mixture of smoke residue
and dust. Check the fans and if such an obstruction
is found, turn the projector off and remove it.
Another reason for the noisy fans could be its damaged
propeller or bearings. If that’s the case, then the fan needs
to be replaced with a new one of the same type.
