manual abstract
Always keep the camera in a horizontal position when transporting. 3. Lens and pick-up tube protection When the camera is not in use, turn Camera OFF and insert the body cap into lens mount hole when the lens is not installed. Avoid turning the power ON with the lens capped as this will shorten the life of the pick-up tube. 4. Never face the camera toward the sun. Whether the camera is in use or not, never face it toward the sun or an extremely bright object, as this will permanently damage the pick-up tube. 5. Do not use the camera beyond its temperature, humidity or power source ratings. (a) Designed for indoor use. Ambient temperature range must not beyond 14°F ~ 122°F (-10°C ~ +50°C). (b) Avoid using the camera when humidity is above 90%. (c) The input power source must be 120V AC 60Hz for WV-140, 24V^2% (21 - 28V) AC 60Hz for WV-144. - 2 - MAJOR OPERATING COMPONENTS (4)Camera Mounting Screw Hole (4) Camera Mounting Screw Hole (3) Mechanical Focus Adjusting Ring (2) Lens (Option) (T) Power Indicator (9) Focus (TÏÏ) Beam in < Rear view of WV-140 > (8) 24V AC Power.

If required, this allows the minimum working distance between the camera and subject to be reduced. In the case of a zoom lens, focus tracking can be adjusted with this control. See page 9. (?) Camera Mounting Screw Holes Standard photographic pan-head screw size (%"— 20). See page 5. (5) Video Output Connector [VIDEO] Use a coaxial cable with a BNC connector. Video output signal is fed to a video monitor or VTR. (D Camera ON/OFF Switch [CAMERA ON/OFF] ® AC Power Cord - Model WV-140 2-wire power cord for connecting to power outlet (120V AC, 60Hz). (D 24V AC Power Terminal Strip — Model WV-144 Accepts 24V AC 60Hz power source. Be sure to connect grounding lead to the GND terminal. See page 8. (D Electrical Focus Control [FOCUS] (QJ) Beam Control [BEAM] These controls have been preset at the factory for optimum picture quality. The user should not change these control settings as this may result in severe degradation of camera performance or permanent damage to the pick-up tube. Readjustment of these controls should be made only by qualified service personnel. See page 9 and 10. INSTALLATION OF CAMERA Mounting at top • This camera is originally designed to be mounted by two — 20 hole © on its top. This hole is the standard photographic pan-head screw size. Y*"-20 Fig. 2 Mounting at bottom • If the camera must be mounted at the bottom's on a tripod, use one W — 20 hole on its bottom. -. It is recommended to mount the camera at the top for stability when the camera with zoom lens whose weight is more than 1.0kg is mounted on the mounting bracket WV-7010/7015. V.__J LENSES Selection of Lens (A) Lens Mounting "C" mount lens may be used. (B) Focal length of lens vs. viewing dimensions. If object size and the distance between the object and the television camera are known, a lens of the proper focal length must be selected. The proper focal length can be determined by the following equations or from the chart shown in Fig. 4. If a specific width must be viewed: f = 6.2 L/W If a specific height must be viewed: f = 4.65 L/H f : Focal length of lens (mm) W: Object width (ft.) H: Object height (ft.) L: Distance between object and television camera, (ft) The height or width of an object, placed at a particular distance that can be picked up with a specific lens, can be calculated from the following equations or from the chart shown in Fig. 4. In case object width is important: I A X I*. 6‘2L (Approx.) W = —-— Object width (ft) Object height is % of object width (ft) In case object height is important: 4 65 L (Approx.) H = — Note: Effective coverage angle will be 5 to 10% less of the following angle because video monitor is generally overscanned 5 to 10%. Focal length of lens Fig. 4 ILLUMINATION About Illumination Generally, the greater object illumination, the higher quality will be the resulting picture. Ambient conditions, object reflection factor, pick-up tube spectral sensitivity loss, and loss of incoming light due to lens aperture ratio must all be considered. How-ever, the following illumination requirements must be met. • Minimum illumination required- for rated equip' ment performance: 1 footcandle (10 lux) (Incandescent lamp; f 1.4 lens used) • Recommended illumination: 10 footcandles (100 lux) CONNECTIONS Coaxial Cable Fig. 5 CAUTION: CONNECT TO 24V AC CLASS 2 SUPPLY ONLY 24V AC 60Hz Power Cable See page 8.
