11 Each REF projector installation should be carefully planned out in advance to insure adequate room for the projector and all external cooling fan and ductwork. The external fan must be wired into the small AC voltage controller assembly block on the rear of the projector, as this insures proper adherence to all local AC electrical codes. This step should ONLY be performed by a certified high voltage electrical contractor. Figure 2.1 External Fan and Ductwork Assemblies Take special note of the air flow direction on the external fan. The direction will be indicated by a small arrow [‐>] on the body of the fan. Test the fan separately to insure correct air flow direction. In all REF projector installations, the fan must be installed and oriented to EXTRACT hot air out of the projector. Attach the exhaust fan with appropriate ductwork to the AIR EXHAUST PORT as noted below in Figure 2.2. Figure 2.2 Projector Intake and Exhaust Ports The external fan responds to temperature increases within the projector and will “spin” accordingly to demand. Insure that all hot exhaust air is routed to some other location well beyond the projector’s physical location. Never allow the hot exhaust air to circulate back into the projector intake. Two air intake ports are available – on the Right Rear or Right Side [when facing the rear of the projector]. Attach your preferred intake line to the external air supply ductwork, and block off the secondary intake port with the supplied chassis cover.
12 The REF projector series operates most efficiently with ambient room temperature air flowing into the intake line; as such it is not necessary to tie the intake line into the residential HVAC system. Use care to insure that the intake and exhaust lines are not “kinked” or otherwise blocked in the final installation. At periodic intervals, perform a temperature systems check of the projector. Select the “Status” option on the Main Menu and review the available internal operating temperatures. Wolf Cinema REFERENCE series projectors successfully operate in the 40‐50 degree Celsius ranges, maintaining cool air flow over all key components. Should you experience operating temperatures beyond that [i.e., above the mid‐60 degree ranges]: • Prepare to power down the projector, but first quickly check the external fan assembly – is it on and working properly? Is the AC voltage block working to deliver current to the fan? Insure that hot air is being properly extracted from the projector. If the external fan is working then power down the projector and review other elements of your installation: • Check for blockage in the intake or exhaust lines – are there kinks in the lines restricting air flow? • Check the external ductwork assemblies – have they slipped off the projector or fan attachment ports? Step 2 – Installing the Projection Lens The projection lens, shipped separately from the projector, must be installed prior to setting up the projector. Remove the lens plug from the lens opening in the projector before installing the lens. Retain the lens plug for projector transportation to protect the optical components from dust and debris. IMPORTANT! The lens seals the projector, preventing contaminants from entering the interior of the projector. Never operate a projector without a lens. IMPORTANT! Remove the rear lens cap from the lens. Keep the front lens cap on the lens to protect it during installation. 1. Rotate the lens clamp to the OPEN position, as indicated below in Figure 2.3:
13 Figure 2.3 2. Align the lens interface plate with the lens mount. Align the lens electrical connector with the mating connector on the lens mount. Fully insert the assembly straight into the lens mount opening without turning. Press using your hand as shown in Figure 2‐4. NOTE: When installing the lens, insure that the lens is not inserted at an angle, as this can cause damage. Figure 2.4 3. While holding the lens flat against the lens mount, rotate the lens clamp clockwise to lock the lens assembly in place. See Figure 2‐5. Figure 2.5 4. Remove the front lens cap. 5. For added stability, fasten the security screws provided with the lens‐mount. See Figure 2‐6. Figure 2.6 6. Use a 5mm hex driver to fasten the red security screws provided with the lens mount (Figure 2‐6). 45:+9 __ Recommended for heaviest lenses such as 0.73:1 and 1.2:1. IMPORTANT: The red security screws MUST be installed when hoisting the projector overhead, or installing the projector in an overhead position.
14 Use of the lens red security screws or the lens retaining screws is required if the projector is hoisted or installed in an overhead position. STEP 2 ‐ Positioning the Projector 2 people are required to safely lift and install the projector. Place the projector on a sturdy, level surface and position it so that it is perpendicular to the screen at a suitable distance. The further back the projector is positioned from the screen, the larger the image will be. To level the projector adjust its feet. With the projector positioned perpendicular to the screen, the image will appear rectangular instead of “keystoned” [trapezoidal]. For more detailed instructions on positioning the projector refer to 2.2.1 “Mounting” later in this section. STEP 3 ‐ Connecting a Source Located at the back of the projector is the input panel where all source connections are made. Each input is clearly labeled for easy identification. Depending on the type of input card installed, connect your source using the appropriate cable(s), as follows: • Analog Input Card: connect 3‐, 4‐, or 5‐wire RGB source to Red/Pr, Green/Y, Blue/Pb, H/C and V using 3, 4 or 5 BNC connectors as required. • Dual 3G/HD/SD ‐ SDI Input Card: connect SDI (Serial Digital Interface) cable to one of the two inputs, 1¬IN or 2‐IN. Both standard‐definition (SD) and high‐definition (HD) 3GHz signals are accepted and automatically recognized on either input. • Dual Link DVI Input Card: connect a single or dual link DVI video signal to the DVI‐I connector, an analog video signal to the DVI‐I connector or an analog video signal to the VGA connector. The DVI signal may contain HDCP (High‐Bandwidth Digital Content Protection). • Twin HDMI Input Card: connect HDMI (High‐Definition Multimedia Interface) cable to one of the two inputs, 1‐IN or 2‐IN. STEP 4 ‐ Connect the AC Line Cord IMPORTANT! Use the AC line cord as provided with the projector. NOTE: Voltage and current requirements are listed on the license label located at the back of the projector. Use the approved North American‐rated power cord as supplied with the projector. If you are connecting to an area outside of North America insure that the appropriately power cord rated for the region of use is used. Plug the power cord into the AC receptacle located at the back of the projector, below the input panel, and the three‐pronged end into a grounded AC outlet. Insure the socket outlet is installed near the equipment and is easily accessible. The input voltage to the projector must be capable of 100 – 240 VAC in both 700W and 1000W models.
15 Always power down the projector before unplugging the AC power cord. Wait 5‐10 minutes for the main exhaust fan to turn off and for the lamp to cool sufficiently before unplugging the projector. Do not attempt operation if the AC supply and cord is not within the specified ratings. On power down, wait 5‐10 minutes for the fans to turn OFF before unplugging the projector. STEP 5 ‐ Power up After the AC Power has been switched on, the LCD display above the keypad indicates “Please wait” and the 4 LED status indicators at the rear of the projector will be solid amber. The projector has reached standby and is ready for use when: • The LCD displays “Standby mode” • The Status LED is solid amber • The Lamp LED is off. To turn on the projector, do one of the following: • Press and hold the power button on either the built‐in keypad or the remote control • Press the power button twice (quickly) on either the built‐in keypad or the remote control The lamp and fans will power on and a green LED will start scrolling back and forth indicating that the projector is in warm up mode. The projector is on and ready to display video when the lamp LED and the status LED are both solid green. NOTE: Insure the external fan is operating properly and extracting hot air from the system. NOTE: See Section 3 Operation for a full description of the status indicators. NOTE: When the projector has a VariScope lens installed and the lens has never been calibrated, there will be a short period where the projector calibrates all of the lens motors (zoom, focus, horizontal, and vertical) by moving them through their full range of motion. You should also select one of the three lens calibration processes to optimize performance at this time, under the Main Menu ‐> Configuration ‐> Lens Settings. Lens VariScope System (LVS™) Calibration To use first insure that the Lens VariScope system is enabled, then calibrate the lens. There are three basic types of lens calibrations. Reference calibration determines a reference point that is used as a defined starting position for relative motion of the lens. All positioning is measured from this reference point. A reference calibration is lost when power is removed from the projector and will occur on every power up as long as LVS™ is enabled. A Motion calibration determines the characteristics of each motor and values are saved in the projector’s memory. If LVS™ is enabled and a motion calibration has previously been done, the projector will automatically recall these settings from memory when it’s being powered up and a motion calibration will not take place. A Full calibration performs both a reference and motion calibration. Automatic LVS Lens Calibration

STEP 6 ‐ Selecting a Source Press one of the input keys on the remote or built‐in keypad to select and display the image for the source you connected in Step 3. STEP 7‐ Adjusting Image Adjust the image settings, such as Brightness, Contrast, Gamma, Focus, Zoom etc. using the direct keys on the remote or built in keypad. NOTE: Refer to Section 3 “Operation” for more details. 2.2 Important Setup and Installation Guidelines Always power down the projector and disconnect all power sources before servicing or cleaning. Refer to Safety Warnings and Guidelines in Section 4 Maintenance. 2.2.1 Installation Considerations Proper installation of your projector will insure the quality of your display. Whether you are installing a projector temporarily or permanently you should take the following into account to insure your projector performs optimally. Choose the installation type that best suits your needs: front or rear screen, floor mount or inverted mount. Front Screen Installations In front screen installations the projector and audience are positioned in front of the screen, which can be flat or curved. Either type may be used with this projector. Some high quality screens offer a gain of about 1 with a viewing angle of almost 180°. This type of screen reflects incident light equally in all directions so the audience can see the display from various angles. Curved screens typically have a gain greater than 1 with a viewing angle less than 180°. This type of screen does not reflect incident light equally in all directions instead it is concentrated in a viewing cone. The audience sitting within the viewing cone area may see a brighter image than those sitting just outside this area.
17 Rear Screen Installations [Folded Optics] In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path, see Figure 2‐7 . The position of the projector and mirror must be accurately set ‐ if considering this type of installation call your dealer for assistance. There are two basic types of rear screens: diffused and optical. A diffused screen has a surface, which spreads the light striking it. Purely diffused screens have a gain of less than one. The main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. This type of screen is suitable when a wide viewing angle is required but there is low ambient room lighting. Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation is created. This type of screen is better suited for brightly lit rooms where the audience is situated within the viewing cone. Figure 2.7
18 Screen Size and Aspect Ratios Choose a screen size which is appropriate for your lens and application. The size of the room and viewing distances are two defining factors: a rule of thumb is that the primary viewing distance should be approximately 1.5 x screen width. There are many popular options regarding ultra‐wide‐screen viewing [i.e., screens that are wider than tall, commonly referred to as ‘Scope, or CinemaScope®]. Such wide aspect ratio screens are perfect choices when mating up to our VariScope™ lens memory system. Discuss your viewing preferences with your Wolf Cinema dealer. Ambient Light Considerations The high brightness of this projector is well suited for locations where ambient lighting might be considered less than ideal for projection. A typical room with ceiling lights and windows rarely requires special attention. Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant. In general, avoid or eliminate light sources directed at the screen. Projector Throw distance Throw distance is the distance measured from the screen to the front of the projector. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be of the right size for your screen. You can quickly estimate the throw distance by taking the horizontal width of the screen and multiplying it by the lens throw ratio. The result of this calculation tells you "roughly" how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. For example, using a 0.75:1 lens, throw distance would roughly be 0.75 x screen width. IMPORTANT: Once you determine the type of lens and screen size you’re going to use, calculate the precise throw distance using formulas from your Wolf Cinema dealer. Due to lens manufacturing tolerances for lens focal length, actual throw distance can vary ±5% between lenses described as having the same throw ratio. Projector Mounting There are several methods for mounting the projector. In typical front and rear screen installations the projector can be mounted to a secure and level surface within a soffit, or affixed to a ceiling mount.
19 Four fully adjustable feet are located on the underside of the projector. Raise or lower these feet when positioning the projector to insure it is level on all sides, so the displayed image will appear rectangular without any keystone. Ceiling Mount The projector can be inverted and suspended from the ceiling using a specially designed ceiling mount WC‐PM‐L. This mounting is recommended for those that want the projector out of plain view or have limited amount of space for the projector. For more information, contact your dealer. Use only the Wolf Cinema approved ceiling mount kit designed for your projector. Refer to the installation instructions and safety guidelines provided in the kit. Vertical and Horizontal positioning The correct vertical and horizontal position of the projector in relation to the screen depends on the lens type and the screen size. Ideally, the projector should be positioned perpendicular to the screen. This way, the image will appear rectangular instead of keystoned (trapezoidal). The vertical position of the image can be offset – that is moved above or below the optical axis (lens center) by adjusting the fully motorized lens mount with the keypad. The amount of vertical offset available depends directly on the lens installed in the projector and can be slightly limited if horizontal offset has been applied. Vertical offset can also be expressed as the percent of half the image height OR the number of pixels of shift from lens center. Refer to Figure 2.1 for some illustrated examples of vertical offset. Table 2.1 along with Figure 2.8 show the maximum vertical offset of a lens; alternatively, how much of your projected image will appear above or below lens center if the maximum vertical offset is applied using that lens. That these values are representations only and will vary based on the type of lens chosen for your installation. Table 2.1 NOTES: 1) Offsets are subject to ±7% centering tolerance 2) % Offset = # pixels of offset / half panel resolution x 100.
20 Figure 2.8 The horizontal position of the image can also be offset – that is, moved to the left or right of lens center, by adjusting the fully motorized lens mount system. The amount of horizontal offset available depends on the lens installed and if the image has already been vertically offset. Horizontal offset can also be expressed as the percent of half the image width – the number of pixels of shift to one side of lens center. Refer to Figure 2.3 for some illustrated examples of horizontal offset. See also Table 2.1 along with Figure 2.9 which shows the maximum horizontal offset of a lens; alternatively, how much of your projected image will appear to one side of lens center if the maximum horizontal offset is applied using that lens.
