Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
OVERVIEW D is a modular rear projection system for the construction of large Display Walls. The technologies used
guarantee the best optical properties for high-quality presentation of information with very simple integration
into higher-level systems.
Although different in screen size and resolution, the various members of the OverView D family all have the
same functionalities, with one exception: projection modules with SXGA+ resolution have two digital inputs, thus
providing redundancy options, cf. Source selection
Technology
VERVIEW D combines the latest modern projection technology with sophisticated electronics and solid mechanics.
O
This design results in high image quality and reliability.
• High, constant reading accuracy over the complete display panel
Optimally adjusted high-performance lens systems guarantee a distortion-free and sharp image.
• Bright displays
A UHP™ lamp provides a high luminous flux, which is passed on at great efficiency by the illumination system. (UHP is a trademark of Philips Electronics N.V.). Depending on the requirements, the illumination unit
can be equipped with 100 W lamps or 120 W lamps.
• Dual lamp system
The projection engines has a dual lamp system and can be operated in three operation modes: hot standby,
cold standby, auto switch mode.
In hot standby both lamps are on. In case of a lamp failure, the light output of the other lamp is immediately switched to illuminate the optics, and there is no noticeable effect on the displayed information: no
loss of information, no impact on quality. Switching time is about half a second.
In cold standby mode the second lamp is only switched on in case a failure occurs with the active lamp.
Since the second lamp needs some minutes to reach a stable operating temperature, at the beginning the
display will have reduced brightness. The contents of information, however, is available nearly without any
interrupt.
Auto switch mode is a special version of the cold standby mode: the lamps are active in turns: after a defined period, the light path is illuminated by the other lamp. Since the lamp is switched on some minutes in
advance, the takeover of the second lamp is nearly not noticeable. The cycle time can be set between
12 hours and 500 hours.
• High contrast
The screen has a surface which absorbs ambient light falling on it and increases the contrast.
• Electromagnetic immunity
Because of the digital projection technologies and their direct digital control O
VERVIEW D guarantees highest
possible immunity against electromagnetic interference.
User friendly
The rear panel of an O
VERVIEW projection cube gives free access to all control elements. The only maintenance
work, i. e. replacing the filter pad and the lamps, can be done within few seconds and makes no re-adjustment
necessary.
Because of the digital projection technologies and their direct digital control, the display is largely flicker-free and
therefore ergonomic.
Environmentally friendly
The burning life of the used lamps is very high. This long lamp lifetime and the low power consumption do not
only reduce the cost of ownership but also contribute to saving energy and natural resources.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
AnOVERVIEW D display wall consists of two main components: the projection modules housing the dual lamp projector and the graphical controller.
2.2.1 Projection module
The projection module is the component for generating the displays of OVERVIEW D The light of a UHP™ lamp is
directed via an optical system to a Digital Mirror Device whose image is projected via a high-performance lens
system onto the rear side of a screen.
Due to the dual lamp system, the availability of the Display Wall is about 100%: in case the lamp fails, the light
output of the second lamp is automatically switched into the light path.
Since the screen is illuminated right up to its edges, it is possible to construct Display Walls of any size by the
adjacent arrangement of several units.
Display Wall consisting of 9 OverView mDG50-DL projection modules
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
Depending on the screen size, OverView D is designed as a dark box mounted on a support, or as a flexible
structure with shieldings. The differences in design are only mechanical, optics and electronics do not differ.
Especially care is taken that no ambient light is falling onto the rear of the screen thus reducing the contrast.
Inside the projection module, the following components are installed: the projection unit with the a single-DMD™
chip, color filter system, illumination and projection optics, the illumination unit (dual lamp system), and a cooling system.
Via a mirror, the image is projected onto the rear of the screen.

• Dual lamp system
The illumination unit can be selected as a 100W model or a 120W model, depending on the overall need of
brightness or power consumption.
The light of a UHP™ lamp illuminates via a transmissive color wheel the DMD.
The projection engines has a dual lamp system and can be operated in three operation modes: Hot Standby,
Cold Standby, Auto Switch mode.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
• In Hot Standby both lamps are on. In case of a lamp failure, the light output of the other lamp is immedi-
ately switched to illuminate the optics, and there is no noticeable effect on the displayed information: no
loss of information, no impact on quality. Switching time is about half a second.
In Cold Standby mode the second lamp is only switched on in case a failure occurs with the active lamp.
Since the second lamp needs about one minute to reach a stable operating temperature, at the beginning
the display will have reduced brightness. The contents of information, however, is available nearly without
any interrupt.
Auto Switch mode is a special version of the cold standby mode: the lamps are active in turns during a selectable cycle time. Alternatingly the light path is illuminated by Lamp top or lamp bottom. Since the lamp is
switched on some minutes in advance, the takeover of the other lamp is nearly not noticeable. The cycle
time can be set between 12 hours and 500 hours.
• Color wheel
The color wheel consists of four segments, one for red, green, blue and white. For XGA and SXGA resolution,
it spins at triple speed (178 Hz), for SXGA+ resolution it spins at double speed.
• DMD
A Digital Micromirror Device (DMD™) is an array of tiny, tiltable mirrors, each of which corresponds to an individual pixel. The mirrors are orientated by applying an electrical signal and can take up alternatively two
positions: tilted +12° (+10°) and -12° (.10°). If they are in the +10° position light is reflected to the screen,
otherwise it is reflected away. The tilting angle as well as the dimenesion of the DMD chips and the number
of active mirrors depends on resolution.
DMD is a trademark of Texas Instruments Incorporated.
• Electronics
The electronics comprises graphics and video signal processing electronics as well as the functionality to
control the projection engine.
The electronics converts the image signals of the graphic card into control signals for the DMD’s. The image is
electronically mirrored in the process and the reversal of the image following the deflection mirror is thus
compensated.
• Data cable
The digital display information is transmitted via a cable directly from the controller
to the DMD control elec-
tronics.
• Lens system
The projection lens system has been especially developed for O
VERVIEW D. It projects the image resulting of
the DMDs via the deflection mirrors onto the rear of the screen module.
• Fan
A fan in the housing ensures that the unit is sufficiently cooled. A second fan positioned beneath the lamp
lift optimizes the air circulation.
• Deflection mirror
Due to folding up the optical path by a mirror the installation depth of the O
VERVIEW D projection unit is ex-
ceptionally small.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The screen consists of a Fresnel lens and a Front Element Screen. The Fresnel lens deflects the light coming from
the projection lens system such that it falls perpendicularly onto the front element screen.
Front element
The front element screen guarantees that the light is distributed horizontally and vertically, while maintaining a
high contrast.
Texture of surface
The surface of the screen has a special non-glare texture. This texture minimizes the direct reflection of the light
of the surrounding and contributes also to the high contrast of the screen.
3.3 Principle of DMD projection technology
For a one-chip projection system, the DMD is sequentially illuminated with the three primary colors, red, green,
and blue (RGB)
principle of a single-chip DLP projection system
Figure 3-2
A condenser lens collects the light, which is imaged onto the surface of a transmissive color wheel. A second lens
collects the light that passes through the color wheel and evenly illuminates the surface of the DMD. Depending
on the rotational state of the mirror (+12 or -12 degrees), the light is directed either into the pupil of the projection lens (on) or away from the pupil of the projection lens (off). The projection lens has two functions: (1) to
collect the light from each on-state mirror, and (2) to project an enlarged image of the mirror surface to a projection screen.
The example shows a color wheel with three segments red, green, and blue. It is also possible that the segments
for the primaries exist twice (RGBRGB), or that a white segment is added (RGBW).

Hot Standby is only available if especially requested!
The active lamp can be selected via the IR Remote Control Unit (RCU) cf. Active lamp. (When servicing and while
standing behind the projection module, the active lamp can also be selected via the manual user interface, cf.
Manual user interface).

3.5 Filter for changing the color temperature (backdrop applications)
OverView D projection systems usually are operated at a color temperature of 6500K (daylight). In broadcast
application it might be required to have the color temperature reduced to 3200 K (reddish). Studios are often
lighted by electrically-generated tungsten light. This light has typically a color temperature of 3200K (reddish).
The cameras are adjusted to this color temperature and show "normal daylight" (6500K) images on TV. In consequence incoming daylight at 6500K or projection systems generation 6500 K will appear blue. Therefore the
display wall has to be set to the same color temperator the cameras are adjusted to in order to be viewed "under normal daylight conditions" on TV.
The XGA projection unit of the OverView D series can be completed by a filter changing the color temperature
from 6500K to 3200K. This filter can be put in placed when required and ensures that cameras adjusted to 3200K
record "normal daylight" when recording the display wall.
Filter active (3200K)Filter inactive (6500K)Projection unit with 3200K filter cartridge
However, the light output of the projection systems with a 3200K filter is about only 58% of the light output of
6500K systems: the lamp employed in the OverView D series have a very small share in the red part of the
spectral range.
Due to the field of application, this filter is only available for XGA resolution: cameras work even at lower resolution.
To compensate the reduction in light output, the projection system can be equipped with a dual lamp illumination unit which houses 2x200W VIP200 lamps.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
3.6 Options for the OverView D series: lamps and color temperature filter
For the OverView D series, there are three different illumination unit which employ 2x100W lamp, 2x120W lamp,
2x200W lamp, respectively. All three of them produce "daylight" at a color temperature of 6500K.
A color filter is available to adjust the color temperature to 3200K.
Whereas all systems can be employed with an illumination unit with 100W or 120W respectively, it's only the
systems with XGA resolution which are available with an illumination unit 200W and a 3200K/6500K color filter
cartridge.
Please keep in mind that the 3200K color filter reduces the amount of light of about
50%. So it is not recommended to use it with 100W lamps, although it technically could
be done.
The ideal illumination unit to employ the 3200K color filter is the 200W illumination
unit.
This combination is usually intended for backdrop applications (broadcast).

Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The projection units of an OVERVIEW D Display Wall are provided with display information by the controller. The
controller is available as a standard X-Terminal with exceptional additional properties or as a Windows
NT/2000/XP Workstation.
3.8.1 Controller as X.11 Terminal
The X Window System (also abbreviated to X.11) was originally developed by MIT as a graphic system for UNIX
workstations. In the meantime, it is available on a large number of computer platforms. These also include operating systems such as VAX/VMS or OS/2 in addition to various UNIX versions.
The X Window System is divided into two parts: The X client and X server are connected to one another by a
communication system (usually TCP/IP). This division permits execution of the X server and X client either on the
same system or also on different systems connected by a network.
The X server is executed on the controller. It implements the graphic display and handles the inputs from the
keyboard and mouse. The X clients can be executed also on the controller or on other systems in the network.
The controller satisfies the X.11 protocol (Rel. 6.), and can thus be used by any X clients, toolkits and window
managers. All X clients (including window managers) use the multi-screen facility without actually 'knowing' this.
Video and RGB Input
The controller has inputs to which video cameras or recorders as well as monitor signals can be connected.
Simple Integration
The controller possesses the generally established interfaces (Ethernet, TCP/IP, X.11 protocol), thus guaranteeing
simple integration into existing computer networks.
Blinking
The controller provides blinking colors (frequencies to DIN).
3.8.2 Controller as Windows NT/ Windows 2000 / Windows XP workstation
If applications based on Microsoft Windows NT or Windows 2000 / Windows XP should be operated via OVER-

All necessary cables are connected to the OVERVIEW D projection module.
4.1.1 Power
Check the power rating on your outlet before connecting the projection modules to the
wall outlet or to a power strip. Contact your facilities manager or a qualified electrician if
you are not sure what type of power is supplied to your building.
The devices are designed to operate with single-phase power systems having a
grounded neutral conductor. To reduce the risk of electrical shock, do not plug into any
other type of power system.
4.1.2 Data
The projection units of an OVERVIEW D Display Wall are connected to the graphic cards of a Barco Controller. The
projector as a DVI interface.
Projection modules with SXGA+ resolution feature two DVI inputs, thus allowing to
connect two sources simultaneously. The source to be displayed then is selected vie the
OSD, as well as the behavior in case a source fails, cf. Source selection
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The projector is switched manually using the power switch [1] located at the rear of the system.
Before switching off (disconnecting from the mains) make sure that the projector is in
standby mode! Never switch off the power switch when the projector is running!
Otherwise settings of the projector which have been changed shortly before mains switch
off might be lost.
4.2 Switching on and off the lamps
4.2.1 Switching on the lamps
Proceed as follows to ignite the lamps:
• Make sure that the projector is switched on.
• Switch on the lamp by pressing the standby key on the IR REMOTE-CONTROL for less than one second.
After ignition of the lamp it becomes gradually bright until it burns stable.
4. Operation
The equipment has a switch-off delay function which prevents the lamp from being switched off
within a period of 30 seconds.
4.2.2 Switching off the lamps
• Switch off the lamp by pressing the standby key on the IR REMOTE-CONTROL for more than one second.
Following switching-off, a switch-on delay function prevents a re-ignition for 30 seconds.
Switching the projector to and from standby as well as selecting the active lamp is done via the OSD.
When servicing, these actions can also be performed using the manual user interface on the rear of the system,
cf. Manual user interface.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The projector can be RS232 remote-controlled or by the IR remote control unit (RCU)
How to use the RCU?
Point the front of the RCU directly at the screen.
When using the wireless remote control, make sure you are within the effective operating distance (30m, 100ft in a straight line). The remote control unit will not function properly if strong
light strikes the sensor window or if there are obstacles between the remote control unit and
the IR sensor.
Remote Control Unit
The remote control unit (RCU) includes a battery powered infrared (IR) transmitter that allows the user to control
the projector remotely.
IR Remote Control Unit (RCU)

The projector's address may be set to any value between 0 and 255 (see 'projector address' in chapter 'Service
mode). When the address is set, the projector can be controlled now by the RCU for addresses between 0 and 9.
The projector can also be controlled by computer, e.g. IBM PC (or compatible), Apple MAC, etc. for addresses
between 0 and 255.
A projector will respond to a RCU set to an address of '0' regardless of what address is set in
the projector itself.
5.3.1 Using the RCU
The RCU is default programmed with address 0, 'zero address'. With that 'zero address' programmed into the
RCU, every projector, without exception will listen to the commands given by this RCU. If it is necessary to control a specific projector, than enter the projector address into the RCU (only when that address is between 0 and
9). The projector with the corresponding address will listen to that specific RCU.
5.3.2 Displaying a projector address
Press the ADDRESS key (recessed key on the RCU) with a pencil.
To continue using the RCU with that specific address, it is necessary to enter the same address with the digitbuttons (address between 0 and 9) within 5 seconds after pushing the address key. For example if the Address
key displays projector address 003, then press "3" digit button on the RCU to set the RCU's address to match the
projector's address. Do not press 003 digits. This will address the remote control to '0' and control all projectors in
the room.
But if you want to enter an address with two digits, e.g. 53, then you have to press “053”, otherwise the projector will accept the first digit (5) as his address.
If the address is not entered within 5 seconds, the RCU returns to its default address (zero address) and control
all projectors in the room.
5.3.3 How to program an address into the RCU?
Press the ADDRESS key (recessed key on the RCU) with a pencil and enter the address with the digit buttons
within 5 seconds after pushing the address key. That address can be any digit between 0 and 9.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
If the optical dimmer has been disabled (e.g. it is broken), brightness and contrast can be controlled directly via
IR RCU. When Brightness or Contrast is pressed, a text box with a bar scale, icon and function name of the control, e.g. ’brightness...’ appears on the screen (only if Textbox in the Installation menu is ON). The length of the
bar scale and the value of the numeric indication indicate the current memorized setting for this source. The bar
scale changes as the arrows on the RCU are pressed.
The picture settings are saved in the image file.
Brightness control
A correct 'brightness' setting is important for good image reproduction.
Use the + button for a higher brightness.
Use the - button for a lower brightness.
Contrast control
A correct 'contrast' setting is important for good image reproduction.
Adjust the contrast to the level you prefer, according to room lighting conditions.
Use the + button for a higher contrast.
Use the - button for lower contrast.
As soon as the optical dimmer is enabled again, these settings get invalid.

The active lamp is the one illuminating the DMD. The currently selected active lamp is indicated with a white dot.
Proceed as follows to change the active lamp
• Use the cursor key to highlight Active Lamp.
• Press Enter to select.
• Use the cursor key to highlight the desired active lamp
• Press Enter to select.
Depending on the operation mode of the projector, changing the active lamp initiate different actions:
Cold Standby or Auto Switch mode
Figure 6-11
Lamps menu, Mode
In this operation mode, the active lamp is on, the second lamp is switched off. Therefore when changing the
active lamp, the second lamp first has to be switched on (and the other lamp is switched off). Since a lamp requires some time to burn stable, the displayed image will first have reduced brightness. After some instants the
image will show the former brightness.
In these operation modes, a subsequent change of the active lamp is only possible after the
cool down cycle of the first lamp (about 30sec).
Hot Standby mode
In this operation mode, both lamps are switched on. Therefore when changing the active lamp, there is no noticeable impact on the displayed image (both lamp are adjusted to have the same brightness).
Since both lamps are one, a second subsequent change of the active lamp is immediately possible.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005

In Hot Standby both lamps are on. In case of a lamp failure, the light output of the other lamp is immediately
switched to illuminate the optics, and there is almost no noticeable effect on the displayed information: no loss
of information, no impact on quality. Switching time is about one second.
In Cold Standby mode the second lamp is only switched on in case a failure occurs with the active lamp. Since
the second lamp needs about one minute to reach a stable operating temperature, at the beginning the display
will have reduced brightness. The contents of information, however, is available nearly without interrupt.
Auto Switch mode is a special version of the ´Cold Standby mode: the lamps are active in turns. Since the lamp
is switched on some minutes in advance, the takeover of the other lamp is equally percepted as in Hot Standby
mode: no noticeable effect on the displayed information, no loss of information, no impact on quality.
The lamp activation time can be selected between 12 hours and 500 hours. Therefore when selecting AutoSwitch, a dialog pops up to enter the auto switch cycle time:
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
Since the light is coupled into the light rod by means of a mirror, the position of the mirror together with the
actual lamp properties determine the light yield.
During the Lamp Optimization procedure, the light output of the active lamp in dependance of the tilting angle
of the mirror is measured, and the optimized mirror position for the lamp is determined.
The procedure should be performed subsequently for both lamps. The optimised positions are stored independently for both lamps, so that after setting the lamp lift in motion and thus changing the active lamp, the mirror
position is adjusted accordingly.

However, when replacing the lamp, it is recommended to select Lamp Optimization, since the
new lamp has different parameters and therefore has to be adjusted anew.

A lamp error occurs if the active lamp fails during operation and if the ignition of the inactive lamp fails, respectively.
The lamp error bit is set, and the lamp lift can no longer be moved!
This error has to be reset manually.
Press the On/Res. switch for about 6 sec. on the rear of the system to reset the error.
Reset the error
• once without doing anything else to make sure that the lamp is really broken
• after a lamp exchange
Depending on the operation mode, the behavior of the system differs.
In Hot Standby mode, after resetting the error, the lamp is ignited. If ignition is successful and the lamp has
been switched on, the lift can be moved again. If ignition is a failure, the lamp error is set again and the lift remains locked.
In Cold Standby mode, since the replaced lamp is the inactive lamp, after resetting the error, there is no lamp
check, and the lamp remains switched off. The lift can be moved again. If then the system changes the active
lamp by means of the lift, the new lamp is tried to be lighted. If it is a flop, the error bit is set again, and within
about 5 seconds, the projector switches back to the lamp which has been the active one. Then the lift is locked
again.
In Cold Standby, after switching the active lamp, the lamp which has been active at that
time is only switched off if the second lamp succeeds in being switched on.
Fan
OverView D series employs two fans: one which is located behind the filter pad frame and connected to the illumination unit and the projection unit, and one which is located beneath the bottom lamp.
Both fans are mandatory for operating OverView D, and in case one of them is out of order, it need to be replaced immediately!
The status of both fans together can be derived from the fan LED. (The fan LED is the bottom LED of the three
status LEDs).
Fan LED green: both fans work
Fan LED is red (static): fans are off!
Fan LED is blinking red: a fan error has occurred. At least one fan is not running
The fan error is an auto-updated error. It’s of no use to reset the error manually since the fan is
monitored continuously. In case the error is solved, error bit is reset automatically. In case the
error persists, the error bit is set (again).
In case the error is not reset automatically, call Barco support.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
A sensor which is located behind the tilt mirror in the illumination unit checks the temperature. In case a critical
temperature (40°C) is reached, the over temperature bit is set, the shut down cycle counter starts its countdown,
and the projector is shut down within five minutes to prevent the system from severe damage.
If desired, the countdown counter can be disabled and thus over temperature protection..
It is highly recommended NOT to switch of over temperature protection.
In case the temperature drops within the countdown period below the critical limit, the countdown counter
stops, and the over temperature bit is reset automatically.
Under Voltage Error
This error occurs if the voltage of the power factor correction board is below a critical limit.
If DMD parking is enabled, the DMD will be parked after 10ms.
If the error is resolved during this time (practical not possible), the DMD parking will not be done.
Illumination unit read
This error occurs if there is no I²C communication between the illumination unit and the projection unit.
This error usually occurs when starting up the projector.
If this error bit is set, the dimmer motor and the motor of the mirrors in the illumination unit are not running.
• Switch off the projector, check the power cable and switch it on again.
It is not recommended to manually reset of the error, since this only affects the error bit,
but not the error itself.
Brightness
Brightness is checked regularly with respect to the target. If the achieved brightness is too high or too low, the
brightness checkbox is ticked.
Manual reset of this error makes no sense.
Lift error
This error occurs if the lift did not reach the switches at its upper and lower end position, respectively.
Manual reset of this error makes no sense.
To solve the problem, call Barco Support!
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
This error occurs if the mechanical dimmer cannot find its home position.
Firmware release 2.0 provides a new algorithm which ensures that there is at least some light on the screen.
With Firmware release 1.x the screen remains dark.
Switch off the projector and switch it on again. If the error still remains, call Barco Support!
Lamp door
This error occurs if a lamp door is opened. When the error bit is set, a counter starts, and if the door is not closed
within the counter cycle of 15minutes, the projector will shut down. If the door is closed within this counter period, the error bit and the counter will be reset, and the projector performs a lamp lift readjustment after closing
the door. This is required since the lamp lift could be at a shifted position.

Display Walls consisting of OVERVIEW D projection modules are adjusted to homogeneous brightness. Therefore all
projectors are individually adjusted to feature this common brightness.
This individual projector adjustment is done after set up of the Display Wall by the Barco Support Technicians. On
the screen, the brightness is measured by means of a lux meter, and the sensor of the optical dimmer (DIS) is
calibrated based on this measurement.
The user can adjust the brightness between 100% and 50% by means of the optical dimmer. This adjustment can
be performed via the command Brightness|Set Brightness.
To adjust the brightness, proceed as follows:

Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The manual user interface located at the rear of OVERVIEW D includes the switches of the illumination unit [1], [2],
[3], the LED’s of the illumination unit, and the LED’s of the lamp doors.
The manual user interface is intended to operate the projection module when servicing. The trained Barco support technicians can analyze errors by evaluating the status of the LEDs.
7.1.1 Power switch
The power switch [1] connects/disconnects the projector from the mains. Once switched on, the projector should
be disconnected from the mains only for servicing.
Do not press the power switch while the projector is running. The projector has to be
switched to Standby first!
7.1.2 Standby switch
The Standby Switch [2] has 3 positions: neutral (not pushed), up (pushed to the top), down (pushed to the bottom).
The switch is slope sensitive and reacts when changing from one position to the other. To prevent operation
errors, a minimum time is required for pushing. After sending a command (after pushing the switch), the next
command can only be sent after the release of the switch for at lease 0.5s.
In case the power switch [1] is off, there is no reaction.

Screens consist of single or double screen elements. Each screen element has a delicate optical screen surface
structure dedicated to its functionality. The optical surface can easily be damaged if the screen is handled incorrectly. Only handle screens while wearing gloves with a soft texture (e. g. cotton gloves).
Avoid touching the rear beaded surface unnecessarily. It is easily damaged.
The screen is a high-precision optical component. It is made of plastic and is not scratchproof. Only use a soft, damp cloth when cleaning.
If the screen is only slightly dusty or is showing particles, a vacuum cleaner with a soft bristle or a feather duster
is recommended. Clean compresses air can be used, but it makes the screen statically charged, attracting airborne particles. The brushing direction should always be along the optical structures in the screen if existing.
If the dirt on the screen is heavier, possibly from fingerprints, soft lint-free cloth or paper towel can be used. If
required the screen may be cleaned with lukewarm distilled water containing mild soap. Never apply cleaning
solution directly onto the screen surface. Instead, add cleaning agent to the cloth or towel, then wipe the surface. It is important that the screen should be completely dry after treatment.
Never use cleaning agents with solvents as these may destroy the screen. Also, never rub hard
or persistently on the screen in order to remove stains, as this will cause deformations in the
surface which will appear as stains.
Don’t store screens at temperatures exceeding 40ºC (104ºF)

In case of a lamp failure, the respective status LED (lamp top: top LED, lamp bottom: mid
LED) blinks slowly red.
The power LED blinks slowly green to indicate a non critical error. For acknowledge, push
up the standby switch for 6 seconds.
Lamp failures can only be detected if the lamp is running.
OVERVIEW D is designed as a dual lamp system. In case a lamp is broken, replace it immediately to ensure to have
a good lamp in case the other lamp fails, too.
If there is no lamp for replacement on stock, DO NOT remove the broken lamp. The
cooling concept requires that two lamps are installed!
After the replacement of a lamp module, the new serial number has to be entered, and the lamp optimization
procedure has to be carried out, cf. Reset runtime, Lamp optimization.
Bevor replacing a lamp module, this lamp has to be inactivated!
Only open the lamp door when the lamp door LED shines red!
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
Lamp failures can only be detected if the lamp is running!
Lamp failures set the Lamp Error Flag.
It is recommended to first reset the flag without replacing the lamp and to retry ignition
after a few minutes. Since the lamps are UHP lamps, e.g. a fluctuation in power voltage
will shut down them and set the error flag although the lamps are still ok. Therefore
always try re-ignition before replacing.
In case Error Box is enabled (cf. Error box), after the detection of a lamp failure the following warning pops up:
Warning
Error on Lamp Bottom occured.
Has the error been solved?
Press <enter> for yes,
<back> for no.
Warning on Lamp failure
Figure 7-1
In case this message is acknowledged YES, the system requires confirmation:
Warning
Are you sure the lamp is
- intact?
- well connected?
Press <enter> for yes,
<back> for no.
Confirmation on lamp replacement
Figure 7-2
In case of a positive acknowledge, the Lamp Error Flag is reset.
In case the warning on lamp failure has not been positively answered, the lamp error stays saved.
The lamp operation mode is still valid, but the lamp lift can no longer be moved.
Press the On/Res. switch for about 6 sec. on the rear of the system to reset the error.
In Hot Standby mode, after resetting the error, the lamp is ignited. If ignition is successful and the lamp has
been switched on, the lift can be moved again. If ignition is a failure, the lamp error is set again and the lift remains locked.
In Cold Standby mode, since the replaced lamp is the inactive lamp, after resetting the error, there is no lamp
check, and the lamp remains switched off. The lift can be moved again. If then the system changes the active
lamp by means of the lift, the new lamp is tried to be lighted. If it is a flop, the error flag is set again, and within
about 5 seconds, the projector switches back to the lamp which has been the active one. Then the lift is locked
again.
In Cold Standby, after switching the active lamp, the lamp which has been active at that
time is only switched off if the second lamp succeeds in being switched on.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
The packaging product uses a strong, highly-resilient low-slip film to surround the lamp module, protecting it
from shock and vibration.
The lamp module is packed between two layers of highly resilient low-slip film. The resilient suspension film is
tough and retains its effectiveness for return shipments and multiple uses.
To ensure that the lamp module is held securely in place the upper layer is pressed against the lamp module and
will pop up when the adhesive tape of the package is removed. Do not jump!
To ensure that the lamp module is held securely in place the upper layer is pressed against
the lamp module and will pop up when the adhesive tape of the package is removed. Do not
jump!
Caution: Don't touch the glass top of the reflector!
Place the cardboard box upright according to the instruction printed on the
box.
Remove the adhesive tape. Be aware that the upper layer will pop up!
Open the box and remove the upper layer.
Take hold of the lamp and lift it out.
Take care that you don't touch the glass top of the reflector!
Now you can insert the lamp as described in the following chapter
If you accidentally made any fingerprints on the glass top of the reflector, clean the glass top
with alcohol before inserting the lamp module!
After the lamp is removed, put the upper layer back in the box. Save the entire
package in case the lamp has to be shipped again.
To ship the lamp module, use the original package and re-pack the lamp module between the
two layers of highly resilient low-slip film.
To pack the lamp module, proceed in the reversed order, please! Don't touch the glass top of
the reflector! Take hold on the fitting and place the lamp module upside down onto the lower
layer. Press the upper layer firmly against it, "opening" on top side, and close the box with
adhesive tape!

7.3.3 Illumination unit with 2x120W lamps or 2x100W lamps
The lamp module must be replaced if a fault occurs and if the lamp does not succeed in re-ignition again.
The cooling concept of OverView D requires that the lamp lift is always armed with two
lamps! Do not remove the broken lamp if there is no replacement for it!
With OverView D, lamps are hot swappable and can be replaced while the equipment is on. When opening the
lamp cover, the lamp driver will be disconnected, and there is no risk of electrical shock. However it is NOT recommended to open the lamp door if the lamp door LED does not show red.
Only open the lamp door when the lamp door LED shines red!
The hot lamp is at high pressure. Do not open the lamp housing before the lamp has
cooled down! Wait at least about 5 minutes after switching off the lamp.
Always hold the lamp by its socket, and never on the glass bulb or reflector! Use fabric
gloves when replacing!
7.3.3.1 Removing the lamp module
• Use a hexagon key size 3 (the key is provided with the system)
• To open the lamp door, a quarter turn counterclockwise will do
• Open the lamp door.

minutes.
If the operation mode of the projector has been Hot Standby, the new lamp is immediately switched on.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
In case the operation mode has been Cold Standby or Auto switch, the lamp will be switched on automatically
in case it becomes the active lamp (i.e. in case of a lamp failure of the other lamp or after the switch cycle.
After the replacement of a lamp module, the new serial number has to be entered, and it is
highly recommended to select the lamp optimization procedure, cf. Reset runtime, Lamp
optimization.
In emergency cases the lamp optimization procedure can be skipped for the moment and carried out later.
7.3.4 Illumination unit with 2x200W lamps
Due to the higher light output of the 200W lamps compared to 100W lamps or 120W lamps, the illumination to
house the 2x200W lamp has a dedicated cooling concept. In addition the lamp modules are different.
The lamp module must be replaced if a fault occurs and if the lamp does not succeed in re-ignition again.
7.3.4.1 Removing the lamp module

A number of design and ergonomic conditions must be considered when planning the installation of OVERVIEW D.
In addition to mounting dimensions, the following sections also include anthropotechnical requirements which
must be observed in a specific application.
Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005
Sufficient floor space and maintenance area must be available when installing OVERVIEW DL
Floor Space
The floor space must have a sufficient load carrying capacity and be sufficiently flat (according to DIN 18202). It
must not sag by more than 1 millimeter under the load of the
VERVIEW D Display Wall. A cement, wood or false floor is permissible.
O
The load of the O
No installations (venting ducts, sockets etc.) must be present in the floor in the area of the feet or of the lower
anchoring devices. An area of at least 15 centimeters must be kept free around each foot. The loading capacity in
the area of the feet must be sufficient. Height differences up to ±5 millimeters can be compensated using the
adjustable feet.
