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 off 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 effects can occur when
the projector and the PC (controller) are not connected
to the same mains power phase due to different 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 effect 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.
