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 o. 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 o 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 o 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.
