BEFORE USING THE PROJECTOR

! Carefully read the precautions on page 3 before installing the projector.

In particular read the following points:

1) Disconnect the power supply before replacing the lamp or doing any maintenance job.

2) Do not open the projector if are not passed at least 5 minutes after it went off.

3) Always wear protective gloves and goggles to replace the lamp or to work inside the projector.

4) The protecting screens, the lenses and the ultra-violet filters must be replaced if visibly damaged.
Slits or deep cuts remarkably reduce their efficiency.

5) To avoid any bad performance of the projector or that the lamp breakage could damage its optic,
replace the lamp as soon as it reaches its average life time (2000 hrs).

6) Periodically clean the in/out air grates.

7) In case the projector must be held on a structure (truss), make sure that it is well and safely fixed,

even using a safety chain from the projector to the structure.

8) Do not install the projector outdoors, directly exposed to rain and moisture.

DMX LINE TERMINAL

Do not connect or wrongly connect the DMX line terminal is probably the most common cause of a defective
functioning of a DMX line.
The DMX line terminal is a resistance placed between the two data pin 2 and 3 at the end of the line.
The terminal resistance should ideally have the same value of the impedance of the DMX connecting cable.
On the MH-250 is inserted a resistance value of 100 Ohm that can be started by a switch placed on the base rear panel
(fig. A).

! It is suggested for all DMX systems to use a DMX line terminal (DMX line terminator ON, fig. A) only on the

last connected unit.

! Usually the DMX connection is insulated from the unit mass. In some cases (very rarely) it is suggested to act

in a different way. On the base rear panel there is a switch that connect electronical the two masses (DMX Gnd).
Use this switch (DMX Gnd ON, fig. A) only if the DMX line functioning is not stable although connection and
termination are correct.

DMX SIGNAL CONNECTION

The DMX signal connection to the MH-250 must be done through the input signal connectors XLR 5 pins, placed
on the rear panel of the projector (fig. 5).
The nomenclature of the pins of the DMX input connectors is listed in the table reported in fig. 5/a.
To avoid any problem in the transmission of the signal it is recommended to use a cable for very fast data transmissions.
A normal audio cable is suitable only for lines long not more than 100mt.
The best performances and the maximum stability are obtained using a shielded microphonic cable which section
must be of at least 2x0,25mm, or, a data transmission cable.
In case of lines long more than 150/200mt. it is recommended to use a DMX Repeater Amplifier.

On the MH-250 control panel (fig. 6) besides the display there are some led and buttons which allow the projector
correct configuration.

LED

• Led “DMX” flashing: the DMX input signal is On;

off: the DMX input signal is Off..

• Led “LAMP OFF” flashing: the control board lamp is Off;

off: the lamp is On.

BUTTONS

There are four buttons which allow the complete programming and management of the projector:

• MENU allows the selection of the

programming options;

the DOWN or UP button until the preferred number will appear. Then memorize it pressing and holding the
ENTER button, until the display stops flashing (the flashing shows that the option selected is different from the
one already set).
To leave the option without changes press the MENU button.

The MH-250, selected for 8 BIT operating, needs 10/11 channels to check its functions.

The relation between channels and functions is described in the following table:

For the complete DMX values see APPENDIX “A”, page 34.

ADDRESS SELECTION

Press the MENU button on the control panel until the Addr option will appear on the display: pressing the ENTER
button, the predetermined channel will appear. To change it use the DOWN or UP button following the example of
fig. 7. When the preferred channel has been reached, memorize it pressing and holding the ENTER button, until
the display stops flashing (the flashing shows that the option selected is different from the one already set).
To leave the option without changes press the MENU button.

The flashing “DMX” led on the panel shows that the data transmission between DMX control and projector is
working.

PROBLEMS AND SOLUTIONS

• All the three led indicate that there are voltages and signals coming from the base circuits:
+30V and +5V come from the board POWER250 (pages 23-27);
DMX comes from the panel board DMX250 (pages 29-30).

To locate the trouble if one of the voltages is not present (for example led +5V off) check that it is off even on the
board POWER250:

2) if the led on the board POWER250 is on, it is necessary to carefully check all connections between the
differnt

boards. Probably a cable is interrupted or one connector is not inserted correctly.

1) if the led is off on the board POWER250, disconnect the circuit MOT250 disconnecting the connector.

If the led still is off, go on with the instructions on page 23 - “POWER SUPPLY BOARD”.
If the led starts, the trouble (probable a short) is located on the circuit MOT250.
In that case, make sure that there is an overheating component. Where possible take it out from the base
and give voltage to the circuit. If the led starts, replace the component.

• If one of the Stepper Motors does not move (i.e. the GOBO wheel):

1) put off the projector and disconnect the connecting cables of the GOBO and COLOUR wheels.

2) connect the cable of the GOBO wheel to the connector of the COLOUR wheel.

3) start on the projector:
3a) if the motor of the GOBO wheel works properly, it is necessary to replace U5 (L6219).
3b) if the GOBO motor still does not work, it is necessary to carefully check it, so as all the connections

circuits (cable and connectors). For a correct check of cables and motors it is possible to effect the
following resistor test:

• between pin 1 and pin 21 (on U5) r =6 ÷ 18 Ohm;

• between pin 2 and pin 5 (on U5) r =6 ÷ 18 Ohm.

• Led +28V OFF
There is not voltage at 28V.
Check that the led +27V on the board POWER250 is on. In case it is, carefully check all electrical connections
between the two boards.

• Led +5V OFF
There is not voltage at +5V.
The voltage at +5V is produced by the +28V through voltage drop, so that it is suggested to check:
R25;
U1.
If these components overheat, there is a short on the line.
Check that one or more integrated circuits placed on the board overheat. If they do, take them out, if possible,
from the base. If the led +5V starts, replace the defective integrated circuit.

• Led DMX OFF
There is not the DMX serial signal.
Carefully check the connections between the board PT3771E and the POWER250 one and between the board
POWER250 and the DMX250 one.

2) if the truoble is still present on the same motor it is necessary to check the correct functioning and all cables.
To correctly check cables and motors it is possible effect resistance measures as follows:

• between pin 1 and pin 4 (on U2 or U3) r =~18 Ohm;

• between pin 19 and pin 22 (on U2 or U3) r =~18 Ohm.

1) if the trouble is reversed replace the defective driver;

• Led +320VDC OFF
There is not voltage at 320V, the power supply stage does not work and all led are off.
Check the fuses of the power supply stage (MAIN FUSE, ELEC. FUSE). If they are interrupted replace them with
others of the same kind. If they are still interrupted there is a trouble on the board.
Check:
VR1 must have resistance R=∞
VR2 must have resistance R=∞
VR3 must have resistance R=∞
Z1 must turn out like a diode
Z2 must have resistance R=∞

if none of the components proves to be defective, replace U1

• LED +27V OFF
There is not voltage at 27V. Disconnect the connectors TO HEAD MOTOR, TO DMX PCB and TO PAN TILT DMX.

• LED +5V OFF
There is not voltage at 5V.

1) If the led starts, there is a short circuit on the power supplied boards. Connect them again to the power
supply stage one per time until the defective one is found out.
When the defective one has been reached go on with repairing or replacement.

2) If the led +27V does not start in spite of disconnecting the power supplied boards, there is a trouble on
the power supply stage, so that it is suggested to carefully check:
