SAFETY PRECAUTIONS

•PROTECTION AGAINST FIRE

1) This unit has been made to work only with the Lamp: MSD 250/2 (PHILIPS).

! ABSOLUTELY NEVER USE OTHER KIND OF LAMPS.

2) Keep a minimum distance of 0,3 mt. from walls or any inflammable surface.

3) Keep a minimum distance of 1 mt. from lighted objects.

4) Replace the fuses with others of the same kind and value (MAIN FUE 5x20 250V 5A; ELEC FUSE 5x20 250V 2A).

5) Do not install the projector close to heat sources. Do not lay the connection cables on the projector when it is hot.

•PROTECTION AGAINST ELECTRIC SHOCKS

1) This projector must be earthed.

2) Class I equipment. The protection conductor must be part of the power supply cable.

3) For the connection to the main power supply proceed as in fig. 2, page 6.

4) Disconnect the power supply before the Lamp replacement or before opening the unit.

5) Do not install the projector outdoors, exposed to rain or moisture.

•PROTECTION AGAINST MECHANICAL HAZARDS

1) When installing the projector use a safety chain.

2) To avoid explosion risks, open the projector only after 5 minutes after the lamp is off.

3) The temperature of the projector can reach 85°C. Wait for almost 5 minutes before operating on it.

4) Replace the Lamp if it is damaged or deformed by the heat.

•PROTECTION AGAINST UV RADIATIONS HAZARDS

1) Do not start on the projector without the protecting screen or if the lenses and the ultra-violet filters are

damaged.

2) The protecting screens, the lenses and the ultra-violet filters must be replaced if visibly damaged and if their

efficiency has been reduced, for example by slits or deep cuts.

3) Do not directly look at the Lamp when it is on.

•WARNINGS

1) Do not dismantle and modify the unit.

2) To avoid any inflammable liquids, water or metal objects entering the unit.

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.

9) Before connecting the projector to the main power supply, make sure that the working voltage and

frequency correspond to the values indicated on the label (fig. 2/a).

The MH-250 is supplied to work at a working voltage of 230V 50Hz (60Hz on request); 1,8A.

For being supplied with a voltage of 100-120V it is absolutely necessary an auto-transformer with

the following characteristics:

• Output voltage 230V.

• Output current 4A.

10) The connection of the projector to the mains is described in fig. 2:

10 a) Do not install the projector close to heat sources. Do not lay the connection cables on the

projector when it is hot.

10 b) The unit must be placed where it could be easily aerated. To avoid obstructing the in/out air

gratings.

10 c) The projector must be distanced almost 0,3 mt. from walls or any inflammable surface

and almost 1mt. from lighted objects.

11) Temperature on the unit’s external surface:

• after 5 minutes Tc = 65°C.

• when the thermic balance has been reached Tc = 85°C.

The unit must be connected to the earth. The inobservance of these

instructions automatically makes the guarantee expiring.

IMPORTANT

1) Disconnect the projector before replacing the lamp. Wear protective gloves and goggles.

2) Unscrew the pawls placed on the rear side of the head (fig. 3).

3) Open the lamp-holder cover placed on the rear side of the head (fig. 3/a).

4) Put the lamp in the apposite lamp-holder (fig. 3/a). Avoid touching the lamp bulb with the nude hands; in case it

accidentally happens, clean the lamp bulb with a dry cloth and alcohol.

5) Close the lamp-holder cover.

To check the lamp average time efficiently, it is suggested to reset the counter (see LHrS function, page 10).

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;

• DOWN allows to run the selected options

back;

• UP allows to run the selected options

forward;

• ENTER confirms the options selected.

DISPLAY

It shows the different configuration menu and the options selected.

BOARD MOT250 (fig. 9)

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:

+ 30V

+ 5V

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.
