Q: Projection is blurred or foggy; static beams (points)
have ahalo around them, but the output window isclean.
How tofix this?
A: This is usually an optical problem such as scratches,
dust and dirt on the components on the beams’ path
from their source to the output aperture (scanner mirror,
dichroic filter, bounce mirror). To inspect and clean the
optical components, the projector must beturned o and
disconnected from the mains power supply.
Use a clean cotton bud (swab) soaked with isopropyl
alcohol to clean the optical component’s surface. The
bud must be“rotated” against movement direction during
cleaning to avoid the surface get scratched by dust and
dirt already taken from the surface. After one whole spin
(360 deg), dispose of the cotton bud and take a new
cotton bud tocontinue the cleaning process. Remember
that the optical parts’ surface can beeasily scratched and
permanently damaged byanincorrect cleaning process.
Q: One ofthe colours fades out and then goes back toits
full power. This repeats. Why isthis happening?
A: The laser projector has automatic over-temperature
protection, decreasing the individual laser module’spower
output to 50% if its temperature goes above the
preset level. After stabilization of temperature, the
output power goes back to 100%. If the temperature
at 50% power output still rises, the power output is cut
to zero until the temperature returns to safe values.
Ifthe projector reduces the power output ofone ormore
colours, the reason for it could be insucient cooling
caused by lack of airflow, too warm cooling air, or faulty
fans onthe main heatsink.
Q: The projection suddenly lost a significant amount
ofblue colour. The colour tone ofall RGB eects changed,
and the total power output decreased too. Why?
A: The most likely reason is the activated Colour
Balance function, which balances all the primary
colours in the correct ration for all the mixed colours
to be precisely right. For example, projected white
is nice and crisp, without discolouration towards blue.
Toenable ordisable this function, press the little button next
tothe FB4 display onthe rear panel. This feature isswitched
ONwhen the yellow LED indicator next tothis button ison.
When the Colour Balance function is disabled, all the
colours goback to100% power output.
Q: How many projectors can I daisy-chain with E-STOP
Remote?
A: The number ofprojectors running onasingle E-STOP
Remote isunlimited. Each projector amplifies the E-STOP
signal for the next projector inline.
Q: What is the maximum distance of the E-STOP
connection between two projectors?
A: The maximum length between two projectors isdefined
bythe internal resistance ofused cable connection wires.
The total resistance of one wire within connection must
be below 400 Ohm. Standard microphone XLR cables
have resistance typically below 0,1 Ohm/meter. So the
maximum distance between two projectors with such
cable isapproximately 4km.
Q: How many projectors can Idaisy-chain with asingle
Ethernet line (PCOUT–> IN1, OUT1-> IN2, OUT2-> IN3…)?
A: We recommended daisy-chaining a maximum
of 6 units on a single Ethernet line. If you connect more
than six projectors, the data packet losses will most
likely be noticeable, resulting in a disruptive movement
ofprojected graphics and animations.
For the best possible quality of multi-laser data
connection, it is recommended to use a high-speed
1Gbit data connection between PCand data switch. Also,
itisrecommended toseparate 100Mbit data connections
between the data switch and each projector.
Q: Is it possible to connect a door switch as a safety
measure tointerrupt the laser emission?
A: Yes. Laser projectors supplied tothe USmarket come
with an E-STOP Remote with Auxiliary Input for Normally
Closed (NC) door switch.
Into this input, the client can connect either an interlock
jumper, a door switch or any additional safety item, e.g.
output of PIR sensor for observing the area around the
laser projector.
Q: Isthis projector compatible with other Kvant projectors?
A: All Kvant projectors manufactured from 06/2014 and
later are fully compatible with each other. To check and
ensure compatibility with older Kvant projectors made
prior 05/2014, please contact the technical support
representative ofKvant Lasers, s.r.o.
Suppose Spectrum LD projector with Saturn9 scanning
set is used with non-LD projectors. In that case,
it is recommended to decrease the maximum size and
scan rate ofthe non-LDsystem(s) tomeet the LDsystem
limits and full compatibility. If more systems from various
manufacturers are used together, it is recommended
to use a separate ILDA signal source for each
manufacturer’sgroup.
