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
6.35X32 T15A/250V . On the PCBs inside the projector there are also 3 fuses. They are 2 fuses 6.3A
250V (fast blow 5mmx20mm) on both Pan PCB and Tilt PCB, 1 fuse 4A 250V (fast blow
5mmx20mm) on driver PCB. 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 operate, 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 2 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.
