Q: Shutter doesn’topen, and its plate blocks the output
(inILDA operation mode).
A: Inthe ILDA operation mode, the shutter isalso controlled
with the “shutter” signal from anexternal controller. Check
the ILDA cable, mainly if pin #13 is connecting properly.
Werecommend using only original ILDA cables.
Q: Shutter doesn’topen, and its plate blocks the output.
A: If the shutter doesn’t open in any operation mode,
please contact your distributor or technical assistance
ofKvant Lasers, s.r.o.
Q: The projector ispowered ON, ready for emission, but
the FB4 display is inactive. And itdoesn’t turn on after
pushing or turning the encoder knob next to the FB4
display.
A: Perform apower cycle procedure with the mains power
switch orunplugging the mains power cable for 5seconds.
After the power cycle, the display should start working
correctly.
Q: One ofthe RGB colours doesn’twork.
A: Check colour settings inthe FB4 menu and make
sure that all R, Gand Bcolours are set at100%. Ifthe
projector doesn’thave abuilt-inFB4 controller, check the
brightness potentiometers atthe rear panel - all three
should beset tothe maximum level.
Ifall the above isasdescribed and the problem persists,
turn o the mains power switch (ordisconnect the mains
power cord) for 10minutes.
All PSUs should fully discharge and cool down.
After 10 minutes, power up the projector. If overloaded
PSUs caused the malfunction, itshould now work correctly
again.
Q: One ofthe RGB colours doesn’twork (ILDA operation
mode only).
A: Check connection onboth ends ofthe ILDA cable and
inspect the ILDA male connector’spins.
Q: Scanning isunstable or distorted on both the Xand
Yaxes (ILDA operation mode only).
A: Distortion of the scanned eects can occur when
the projector and the PC (controller) are not connected
tothe same mains power phase due todierent PEwire
potentials (Earth).
Always connect the PC/controller and the laser projector
tothe same mains power socket when operating inILDA
mode.
Q: The projection size isreduced toabout 50% onone
orboth ofthe Xand Yaxes.
A: Check Master Settings inthe FB4 menu and ensure both
axes size are set to100% size. Ifthe projector doesn’thave
FB4 controller build-in, ensure both Xand Ypotentiometers
located onthe rear panel are set tothe maximum level.
Ifall the above isasdescribed and the problem persists,
check ILDA cable connectors onboth sides and the ILDA
input connector onthe projector. One or more of#1, #2,
#14, #15pins may bebent ordamaged.
Q: One colour ofthe projected eect isshifted out from
others - misaligned.
A: Itisnecessary toreset the output directions (alignment)
of individual colours (laser beams) inside the projector.
There are several ways how tojoin them together, but only
one is correct. The correct one ensures perfectly joined
beams atboth short and long-distance projections. Please
check the User manual (chapter Beam alignment) for beam
alignment instructions.
Q: Projector #2doesn’twork when connected tothe ILDA
output ofprojector #1.
A: Try toreplace the ILDA cable with anew one between
projectors and check the ILDA input connector onprojector
#2for any damage. Ifthis does not solve the issue, exchange
the projectors one for another and see if that works.
Ifboth work fine, then projector #1has faulty ILDA output.
If none of them is working, then projector #2 has faulty
ILDA input. Please contact your distributor or technical
assistance ofKvant Lasers, s.r.o. for further help.
Q: Projection is blurred or foggy. Static beams (points)
have ahalo around them. 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; oronthe aperture glass itself.
Use aclean fine-cotton cloth soaked with isopropyl alcohol
toclean the surface ofthe output window. Clean itcarefully
soyou won’tscratch the surface with dirt particles already
stacked tothe cloth.
Remember that the output window’s anti-reflex surface
can be easily scratched and permanently damaged
byanincorrect cleaning process.
