2 Abbr eviated Summary This chapter provides a summary of the system components and characteristics.
2.1 Design OVERVIEW CDG67-DL 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. Technology OVERVIEW CDG67-DL combines the latest modern projection technology with sophisticated electronics and solid mechanics. This design results in high image quality and reliability.
Flexible Configuration OVERVIEW CDG67-DL projection modules can be combined in rows and columns to realize Display Walls of virtually unlimited size. The set up of the projection modules can be linear or curved.
2.2 Compo nents of an OVERVIEW CDG67-DL DISPLAY WALL An OVERVIEW CDG67-DL Display Wall consists of two main components: the projection modules housing the dual lamp projector and the graphical controller. 2.2.1 Projecti on Module The projection module is the component for generating the displays of OVERVIEW CDG67-DL. 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.
2.2.2 GRAPHIC AL CONTROL UNIT The projection unit of OVERVIEW CDG67-DL is provided with display information from the graphical control unit.
3 Desig n and Functions This section provides a technical description of the equipment listing the fundamental characteristics and functional principles.
3.1 Project ion Module The projection module OVERVIEW CDG67-DL has a display area of 1026 millimeters high and 1368 millimeters wide. The resulting screen diagonal of 1710 millimeters corresponds to approximately 67 inches. Figure 3-1 OverView cDG67-DL The shielding prevents ambient light from falling onto the rear of the screen and thus reducing the contrast.
3.2 Inside the Structure The structure houses 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.
Color Wheel The color wheel spins at 178 Hz and consists of four segments, one for red, green, blue and white. 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° and -12°. If they are in the +10° position light is reflected to the screen, otherwise it is reflected away. The projector employs a 0.
3.3 Screen The image is generated in the screen . It consists of the optical screen and a frame with which the screen is exactly mounted onto the structure. Fresnel Lens 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.
3.5 Princip le of Dual Lamp System The dual lamp system implemented in OverView cDG67-DL is based on a lamp lift which moves the respective lamp in front of the stationary optics. The lamps are moveable The optics is stationary The following identies apply: Lamp Top == L1 Lamp Bottom == L2 The lift is the carrier of the lamps and can have two positions: lift up and lift down.
Each of this states can be combined with one of the lift positions: Liftposition Liftposition L2 L1 L1 L1 P L2 Liftposition Liftposition P L2 L1 P L2 P up up up up down down down down Hot standby Hot standby, moment of lamp failure Cold standby / Auto switch Both lamps are switched off, projector in standby Liftposition L1 Liftposition P up L1 P up L2 Liftposition Liftposition L1 L2 L1 P P up up L2 L2 down down down down Hot standby Cold standby / Auto swi

7 Main tenance and Servicing OVERVIEW CDG67-DL requires very little maintenance and servicing. Maintenance operations are nevertheless necessary at regular intervals to guarantee good operational performance. This chapter describes maintenance and servicing of OVERVIEW CDG67-DL.
7.1 Manua l User Interface The manual user interface located at the rear of OVERVIEW CDG67-DL 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 S witch The power switch [1] connects/disconnects the projector from the mains.
7.1.3 Active L amp Selection Switch The Active Lamp Selection Switch [3] 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.

7.2 Cleanin g the Screens 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.
7.3 Replac ement of Lamp Modules 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 CDG67-DL 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.
7.3.1 Behavio r on Lamp Failure Lamp failures can only be detected if the lamp is running! Lamp failures set the Lamp Error Flag 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 for yes, for no.
7.3.2 Unpack ing a Lamp Module 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.
7.3.3 Removi ng a Lamp The lamp module must be replaced if a fault occurs. 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 cDG67-DL, 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.
Now you can see the lamp, fixed into its position by means of a securing ring [1]. 1 Figure 7-4 inside the lamp housing Press the securing ring, and turn it counterclockwise until the hooks are released from the guide rods. Figure 7-5 the securing ring Remove the securing ring Withdraw the lamp module. While withdrawing, the plug is disconnected.
7.3.4 Disposi ng Lamp Modules Note that there may be laws concerning disposal and recycling of burnt-out lamps in your country! Please contact your local authorities to get further information! 7.3.5 Insertin g a Lamp Module The following description applies if the lamp has already been removed as described above and the lamp cover is still opened. Fetch the lamp module on its housing. The power socket is on the right side. Insert the lamp carefully.
Figure 7-9 inserting the securing ring Close the lamp door Use the screw driver and lock the lamp door by turning the screw a quarter turn clockwise. The lamp door must not be open for more than 15 minutes. If not closed within this period, the projector will show a warning, and then go to standby after another 5 minutes. If the operation mode of the projector has been Hot Standby, the new lamp is immediately switched on.
7.3.6 Replaci ng the Filter Pad The filter pad must be replaced regularly. The operating period of a filter pad depends on the quality of the supplied air. Switch the projector in Standby mode. Switch off power by pressing OFF. Switch off the equipment before replacing the filter pad in order to avoid severe contamination of OverView cDG67-DL Lift the cover of the filter pad slightly and remove it.

10 Conf iguring Notes A number of design and ergonomic conditions must be considered when planning the installation of OVERVIEW CDG67-DL. In addition to mounting dimensions, the following sections also include anthropotechnical requirements which must be observed in a specific application.
10.1 Floor S pace and Maintenance Area Sufficient floor space and maintenance area must be available when installing OVERVIEW CDG67DL 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 OVERVIEW CDG67-DL Display Wall. A cement, wood or false floor is permissible. The load of the OVERVIEW CDG67-DL is transmitted to the floor via adjustable feet.
Maintenance Area The floor space for OverView cDG67-DL is calculated from the basic area of the structure. A maintenance area must be provided behind each OverView cDG67-DL over the complete width. This area must be permanently accessible. The exact regulations for such a maintenance area can be obtained from the specifications for working premises.
10.2 Overal l Height The installation room must be sufficiently high. Sufficient space (recommended > 150 millimeters) must be provided above the OVERVIEW CDG67-DL projection modules. The total height results from the height of the structure plus the vacant space above the modules. Figure 10-2 Mounting dimensions of OVERVIEW CDG67-DL (All dimensions measured in millimeters!) The depth of the OVERVIEW CDG67-DL is 940 mm. The standard support height with the adjustable feet is 1287,5mm.
10.3 Viewin g Distance and Angle When planing the installation of OVERVIEW CDG67-DL, anthropotechnical factors such as the human field of vision must be considered in addition to design requirements. General rules for the viewing angle and distance will not be specified here since they depend on the field of application. The notes in this section are therefore only recommendations which can be observed for a particular application.
The screen of OVERVIEW CDG67-DL can be viewed at angles greater than 45 degrees without problems. The vertical viewing angle has been designed such that there is no difference whether the observer is standing or sitting. In addition to the viewing angles, the room illumination should also be considered when installing OVERVIEW CDG67-DL. Diffuse ambient light measured horizontally up to 300 lux and vertically up to 500 lux is no problem if the displayed image has a sufficiently high contrast.
