If the projector’ s lens becomes damaged or broken it should be replaced. If the lamp becomes
damaged or deformed in any way it must be replaced. If the light from the lamp appears dim this
would normally indicate that it is reaching the end of its life and it should be changed at once, aged
lamps run to the extremity of their life might explode. If the projector does not function, check the
fuses on the power socket of the projector, they should only be replaced by fuses of the same
specification
(200/220/230/240V: 6.35x32 T7A/250V; 100/120V: 6.35x32 T15A/250V) . On the
PCBs inside the projector there are also 3 fuses. They are 1 fuse F2A 250V 5mmx20mm on Pan
and Tilt PCB and 2 fuses F2A 250V 5mmx20mm on 2 SLAVE PCBs. Should these be damaged call
a qualified technician before replacement. The projector has thermal protection device that will switch
off the projector in case of overheating, should either of these operation, check that the fans are not
blocked, and if they are dirty clean them before switching on the projector again. Check that the fans
are operational, if not call a qualified technician.
Any maintenance work should only be carried out by qualified technicians.
To ensure the continuous rotation of the rotating gobos and linear motion of the lens for focusing,
it is recommended that the bearings for the rotating gobos and the 3 shafts for the focusing lens
holder be lubricated periodically, preferably every two months. Use only high quality, high-
temperature resistant grease instead of any type of oil. When lubricating the bearings, a syringe
with a fine needle is the easiest way to introduce the grease to the bearings around each gobo.
To ensure the reliability of the projector it should be kept clean. It is recommended that the fans
should be cleaned every 15 days. The lens and dichroic colour filters should also be regularly cleaned
to maintain an optimum light output.
Do NOT use any type of solvent on dichroic colour filters.
Cleaning frequency depends on the environment in which the fixture operates: damp, smoke or
particularly dirty surroundings can cause greater accumulation of dirt on the unit’
s optics. A soft cloth
and typical glass cleaning products should be used in cleaning. It is recommended to clean the
external optics at least once every 20 days and clean the internal optics at least once every 30 / 60
days.
Do not use any organic solvent, e.g. alcohol, to clean the reflector mirror, dichroic colour filters
or housing of the apparatus.
PROBLEM POSSIBLE CAUSE ACTION
The projector doesn’ t switch
on
-The power supply is not
present
-The lamp doesn’
t work
Check the fuse on the power
socket.
Replace the lamp.
The lamp comes on but the
projector doesn’
t respond to
the controller
-Wrong DMX configuration
and/or start address
- Defective DMX cable Make sure that the projector is
correctly configured.
Replace or repair the DMX cable.
The projector only functions
intermittently -The fan has failed Make sure the fan is working and
not dirty.
Defective projection -The lens is broken
-Dust or grease on lenses Check the lenses are not broken.
Remove dust or grease from the
lenses.
The projected image
appears to have a halo -Installation of the lamp is not
correct
-Dust or grease contamination
on the optics. Make sure the lamp is installed
correctly.
Carefully clean the optical group
