4.0 INSTALLATION 1. Remove the six (6) Phillips screws that hold the upper cover to the camera body and remove the cover (refer to Figure 2). 2. Set the internal switches according to the conditions in which the camera will be used (refer to Figures 2 and 3). Switch Settings AGC ON OFF (gain: 0 dB) CCD IRIS* ON OFF SHUTTER (only effective when CCD IRIS is off) 0: 1/60 s 4: 1/1000 s 1: 1/100 s 5: 1/2000 s 2: 1/250 s 6: 1/4000 s 3: 1/500 s 7: 1/10000 s * When using a manual iris lens, the CCD IRI

3. Replace the upper cover on the camera body. 4. Make sure that you have the right type of lens to install on the camera. The lens must be a C-mount type, and the screw thread must not project more than 9 mm (3/8-inch) from the lens mounting surface (refer to Figure 4). This camera uses a 1/2-inch CCD, so the lens should be for use with this size of CCD. If you use a lens for a 2/3-inch CCD, the angle of view will be differ- ent. 5. If you have an auto-iris lens, replace the plug on the lens ca

6. When using an auto-iris lens, install it as follows. For a manual iris lens, omit step c. Refer to Figure 6. a. Unscrew the lens mount cap (1). b. Screw in the lens (2). c. Plug in the lens cable (3). Figure 6. Lens Installation 7. Attach the camera to a mounting bracket with a mounting screw of the type shown in Figure 7. 1/4" UNC (20 pitch) d = 4.5 mm ±0.2 mm (ISO standard), or 0.197" (ASA standard). Figure 7.

8. Connect power to the camera (refer to Figure 8). This camera must always be operated with a 24 VAC class 2 power supply. In the U.S.A., use a power supply that is UL Listed. In Canada, use a power supply that is CSA Certified. Refer to Table A for wiring distances. When using a transformer without a ground lead (two-lead type), connect the output of the transformer to the 24 VAC 1 and 2 terminals of the camera. Connect a ground lead to the GND terminal or an irregular voltage may be generated

Table A. 24 VAC Wiring Distances The following are the recommended maximum distances for 24 VAC applications and are calculated with a 10-percent voltage drop. (10-percent is generally the maxi- mum allowable voltage drop for AC-powered devices.)

4.1 ADJUSTMENTS Turn on the camera power and make the following adjustments. 4.1.1 White Balance After fitting the lens and making all the installation connections, use a monitor to check the picture and set the white balance as described below (refer to Figure 9). AWB (Automatic White Balance) mode: This mode is appropriate when lighting conditions are more or less constant. Point the camera at a white object, such as a white wall or piece of white paper, so that the monitor screen is as far a

4.1.2 Vertical Phase Use the V PHASE (vertical phase) button to compensate for vertical phase discrep- ancies that may occur when two or more cameras are used when the SYNC switch is set to L.L. Use the tip of a ballpoint pen or the like to press the button. Each time it is pressed, the line lock position shifts by 60°. Vertical phase adjustment is not vertical roll adjustment. Vertical phase problems arise when: 1. Switching rapidly between widely separated cameras with manual or sequen- tial

Zoom Lens Models 1. With the camera operating, view an object at least 75 feet away. 2. Make sure the lens iris is wide open.* If outdoors use a neutral density filter in front of the lens to insure that the iris is fully open. 3. Set the lens focus to infinity. 4. Adjust the lens zoom to extreme WIDE angle. 5. Adjust the back focus to bring the object being viewed into the sharpest focus (the filter must be in place if the adjustment is being made outdoors). 6. Move the lens to extreme TELEPHOT
