8.0 ORDINARY MAINTENANCE
Ordinary maintenance on the projectors
PERFORMANCE 1200 DVP
is
necessary to maintain the perfect efficiency of the unit and to avoid defects
like the low luminosity of the light beam, irregular motion of the mirror or ot-
her rotating components. In the fi-
gures
you
can
see
those
components that can easily accu-
mulate dust and grease. Clean
them using a soft cloth and com-
mon glass-cleaners. As regard
the picture on side, the intervention must be effected by a mechanical
maintenance operator, who will clean the anti-heat filter, reachable only
from the inside of the projector.
8.1 EXTRAORDINARY MAINTENANCE
To make an extraordinary maintenance, it is necessary the presence of a generic or quali-
fied mechanical operator, according to the type of the needed intervention. To make an ex-
traordinary maintenance, it is necessary the presence of a generic or qualified mechanical
operator, according to the type of the needed intervention. To make it simple, we advice to
completely extract the mechanical part of the
PERFORMANCE 1200 DVP
from its box : look
figure where you can see the 4 hexagonal screws (
A
); the 2 focus bracket screws that have to
removed, so that you can extract the whole mechanical part, supporting the motors and the
various wheels ( effects, color, gobos). In this way it will be much more easy to observe the
components to maintain and/or replace. In the following figures it’s possible to observe the dif-
ferent particulars that have to be cleaned and, at the same time, the whole mechanical struc-
You must particularly take care of the sensors which are really fundamental in the unit working.
The sensors are absolutely necessary when a general reset of the projector is needed. If this function is not cor-
rectly executed, it will totally compromise the regular working of the projector, at least for the group referred to the
sensor itself. Es : when there’s an irregular reset of the color wheel, all the setted colors will not correspond to the co-
lours listed in the chapter about DMX digital values.
The same situation will occur in the case of the gobos wheel or the effects wheel.
The section shutter/strobo/dimmer doesn’t use sensors during the reset
positioning but it’s conditioned by a mechanical beat of the shutter shovels.
You must carefully clean also the moving zoom lens. After several wor-
king hours dust and grease will be stored on this lens, carried inside the
projector by the cooling fans.
