2.3 PROJECTOR INSTALLATION
To fix the MP250 Fresnel is necessary, when the installation has to be on a raised-from-the ground support, to
block the fixing bracket of the unit by means of a screw provided with nut and locknut measuring not less than
M10X50, to insert in the central pre-arranged hole on the fixing bracket.
In order to guarantee a necessary security and in respect of the actual safety rules concerning the projectors’ in-
stallation, it is compulsory to install a safety-chain (or steel cable), equipped with spring clips, to connect the MP250
Fresnel‘s body to the fixing structure.
ATTENTION: the safety-chain must be properly installed and fixed to the supporting structure, in a way that an
incidental giving in of the main bracket would leed to the shortest possible fall of the projector. After such an inter-
vention the safety-chain must be replaced.
ATTENTION: COEF is not responsible for installations not correctly made or made without respecting the
above indications: those installations are considered dangerous.
2.4 ADVICES FOR A CORRECT INSTALLATION
The following conditions have to be respected for a correct operation:
1) Do not install the projector outside where the influence of atmospheric factors could damage the unit work-
ing (rain, wind, intense heat etc.).
2) Do not clean the projector using water jets or immersion in different liquids. Scrupulously follow the indica-
tions given in the chapter MAINTENANCE.
3) Make the electric connections and the installation / replacement of the lamp after haved disconnected the
power supply and after haved positioned the power switch to OFF.
4) Do not touch in any case the internal and external parts of the projector without previous authorization of the
constructor and make modifications only by the intervention of qualified staff.
5) Make sure that the projector is correctly fixed on the support as indicated in par.2.3.
6) Minimum distance from illuminated objects: The projector must be positioned in such a way that objects
struck by the light beam are located at least 1,5 metres from the projector objective.
7) Minimum distance from inflammable materials: 0.3 meters
8) MAX ambient temperature: 40° C.
1,5 m

3.1 DMX 512 CONNECTIONS
FROM CONTROL UNIT
Connect the projector to the control unit by means of a RG58 or RG59 coaxial cable supplied with 3 Pin XRL
Cannon plugs and connectors. Respect, according to the indications on the panel, the input and the output of the
DMX 512 signal.

Pag. 8 http://www.coef.it - [email protected]
On switching the projector on, the display will indicate the type of projector and the version of control software
which have been installed. To this purpose, please remember that this type of projector belongs to a new generation
of projectors, designed with the possibility of updating the software version through the normal DMX connection by
means of a programmer deliberately created: UNI-PROG 8.
After the indication MSTR HOME, the projector carries out the RESET and gets ready to be controlled from the
connected console.
The display will indicate 1 as default value. This means that the first channel occupied by the projector will re-
spond to the values sent to channel 1 by the DMX line. This also means that according to the total number of chan-
nels assigned to the projector by means of the CH89 function, MISC menu (see Table 4.1 Menu/Fuctions), we shall
be able to check the MP250 Fresnel with the 1 to X channels (8 or 9 according to how the setting is) of the DMX line.
This enables us to make MP250 Fresnel (which we are installing) completely independent from control or integral
with any other installed projector.
General Rules:
Refer to the Table of Section 4.1 in the following page.
By each pressure, Button MENU (E) permits to go backwards by one level.
GandH(DOWN and UP) buttons select functions and sub-functions.
Button F (ENTER) enters the function and confirms a control.
By pressing Button MENU (E) and buttons UP and DOWN (H and G) you can select the menu you have to mod-
ify.
Once the wished menu is reached, press Button F (ENTER) to confirm your selection and enter the function.
Press G or H to enter the sub-functions if available.
Always confirm your selection with ENTER.
Press MENU to go out of the function and press again to go back to the starting level.
Example: We installed our projector on the ceiling and for this reason we want the visualization of the display to
be correct.

Following the picture, you can see all the offered possibili-
ties in detail.
All operations are to be carried out with the E,F,G,Hbut-
tons, respectively indicated as MENU,ENTER,DOWN and
UP.
The display Dwill inform you about the selected functions.
The 3 A,B, and Cleds will allow you to know:
A= reception of the DMX line.
B= lamp ON.
C= errors indicated on the ERR table.

6.0 ORDINARY MAINTENANCE
The ordinary maintenance is fundamental for the perfect efficiency of MP250 Fresnel, in order
to prevent any functional defect as a reduced light beam or irregularities in the movement of the pro-
jector 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.
To let you operate more easily, we advice you to remove the two top covers of MP250 and the two basis covers.
In order to put again the cover to its place, operate as shown below:
A) Positionate the top cover on the MP250 FRESNEL projector.
B) Screw down the frontal screws (objective); not yet those on the back (lamp).
C) Insert the 2 rubber front parts, guiding them to the end of their position.
D) Remove the lamp cover and insert the two remaining rubber packings, guiding them to the
end of their position.
E) Block carefully the four screws.

http://www.coef.it - [email protected] Pag. 13
6.1 EXTRAORDINARY MAINTENANCE
To make an extraordinary maintenance, it is necessary the presence of a generic or qualified mechanical opera-
tor, 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 Fresnel 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 figures 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 fundamental in the unit working.
The sensors are absolutely necessary when a general re-
set of the projector is needed. If this function is not correctly
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 colours listed in the
chapter about DMX digital values.
The section shutter/strobo doesn’t use sensors during the
reset positioning but it’s conditioned by a mechanical beat of
the shutter shovels.

Pag. 14 http://www.coef.it - [email protected]
6.2 ELECTRONIC MAINTENANCE
This section is dedicated in detail to the electronic connections between the card and the mechanical compo-
nents, assembled in the projector. These informations will be absolutely necessary when the mechanical unit has to
be removed from the projector for maintenance and/or repair.
The connections are made using handy connectors and are detailed where you can find indications about the
connection between a specific connector and a specific component of the mechanical unit. This includes the motors
and the sensors of the various effects wheels ( color 1, color 2, shutter etc.).
WARNING! An improper use of this documentation made by not specifically qualified staff can damage
irremediably the electronic and/or mechanical components of the projector.
