MASTER / SLAVE SYNCHRO MODE
Without using a controller, many projectors can run synchronously in the Master/Slave mode by linking them
with each other.
Select one projector as the master with setting the DMX start address at random. Regard the other projectors
as the slaves setting all DMX start address “001”.
Connect the master’s output to the first slave’s input, and connect the first slave’s output to the second slave’s
input. The rest may be deduced by analogy. Eventually connect the last slave’s output to a DMX terminator as
shown in the figure below.
MAINTENANCE
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, old lamps run to the extremity of their life can
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 specified value 6.3A/250V. On the main PCB inside the projector there is
also a fuse rated 4A/250V. 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.
KEEPING THE PROJECTOR CLEAN
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
color filters or housing of the apparatus.
LUBRIFICATION
To ensure the continued smooth rotation of the rotating gobos it is recommended that the wheel is lubricated
periodically, preferably every two months. Use only high working temperature low viscosity oil, a syringe with a
fine needle is the easiest way to introduce the oil to the bearings around each gobo. Do not over lubricate as
this will cause spillage when the wheel rotates.
