9.0 ORDINARY MAINTENANCE
The ordinary maintenance is fundamental for the perfect efficiency of MP250 Zoom, in order to
prevent any functional defect as a reduced light beam or irregularities in the movement of the projec-
tor or of other rotating parts.
The parts which need more maintenance are shown in the figures. In order to free them from
dust or grease, clean them with a soft cloth and normal products for windows cleaning.
9.1 EXTRAORDINARY MAINTENANCE
To make an extraordinary maintenance, it is necessary the presence of a generic or qualified me-
chanical operator, according to the type of the needed intervention.To let you operate more easily,
we advice you to remove the two top covers of MP250 Zoom and the two basis covers. In this way it
will be much more easy to observe the components to maintain and/or replace. In the following fig-
ures it’s possible to observe the different parts that have to be cleaned and, at the same time, the
whole mechanical structure mounted with all its components is shown.
You must particularly take care of the sensors which are really funda-
mental in the unit working.
The sensors are absolutely necessary when a general reset of the pro-
jector is needed. If this function is not correctly executed, it will totally com-
promise 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 col-
ors will not correspond to the colours listed in the chapter about DMX digital
values.
The same situation will occur in the case of the gobos wheel .
The section shutter/strobo doesn’t use sensors during the reset position
-
ing but it’s conditioned by a mechanical beat of the shutter shovels.
