Q: My projector’s aperture glass is cracked, broken
ormissing. Can Icontinue using myprojector?
A: Laser beams hitting glass splits will be scattered into
unwanted directions, creating arisk ofdamage toeyesight,
health orproperty. Broken ormissing aperture glass enables
humidity, water, and dust inside the laser projector’soptical
compartment, which can cause permanent damage tothe
system.
Itisessential toreplace the damaged ormissing aperture
glass before using the laser projector.
Q: The housing of the projector is damaged. Can
Icontinue using myprojector?
A: The projector must not be operated if the housing
isdamaged tothe level that itcauses visible gaps between the
projector’sadjacent faces. The gaps enable humidity, water,
and dust inside the laser projector’soptical 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 berepaired
orreplaced before operating the projector again.
Q: Projector’s eyebolt is bent, fractured or unscrewed.
Can Icontinue using myprojector ifitis installed using
the eyebolt asasafety mechanism? Orcontinue with the
installation?
A: No! The projector must not beused, lifted orhanged.
Never attempt torepair bent orfractured eyebolt. Replace
itwith anew one with the same orhigher load capacity.
Q: Isit 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 at100% speed for about
2seconds. Then their speed isadjusted according tothe
heatsink’stemperature.
Clubmax (without FB4):
ifheatsink’stemperature isbelow 25°C (77°F), the fans are
turned o. Within the range of25°C(77°K) to55°C(131°F),
the fan speed increases with increasing temperature
ofthe heatsink, and over 55°C(131°F) they run atfull
speed.
BeamBrush, Clubmax FB4, Atom and Spectrum series:
ifheatsink’stemperature isbelow 15°C(59°F), the fans are
turned o or run at low speed. Within the range of 15°C
(59°K) to33°C (91°F), the fan speed increases with increasing
temperature ofthe heatsink, and over 33°C (91°F) they run
atfull speed.
Q: IsitOKifsome fans are running atfull speed and some
atlow speed during the operation?
A: Yes, itisOK. 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 ofall fans can bechecked
anytime by power cycling the projector. After powering
upthe projector, all cooling fans will run at100% speed for
about 2seconds. Then their speed isadjusted according
tothe heatsink’stemperature.
Q: Cooling fans generate a strange noise. Is that
aproblem?
A: Strange noise isusually 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 o and remove it.
Another reason for the noisy fans could be its damaged
propeller orbearings. Ifthat’sthe case, then the fan needs
tobereplaced with anew one ofthe same type.
