2 PREPARATION 2-1 Initialize Operation This lens has a built-in encoder for a position sensor of zoom, iris and focus, and enables high-accuracy control and advanced for virtual interface. The correct position must be detected for these functions to operate correctly. The ON [Auto]/OFF [Manual] setting of initialization can be set from the information display. ON [Auto] OFF [Manual] The lens is automatically initialized on power-up. (When in servo mode) After the power is turned on, position detection is performed when the lens passes the specific position (normally near the center) in the course of lens operation. * Default setting at factory: OFF • During initialization, lens operation is disabled. After initialization is completed, the lens returns to the position where it used to be before initialization. However, if the lens is operated in the position servo mode, the lens moves to the currently controlled position. • The initialization operation can be enabled/disabled on the information display. When any initialization operation is changed, turn off then on the power for the changes to take effect. The "Initialize Error!" message appears when the servo module is not mounted correctly, the lens is forcibly locked, or some other reason. In such case, check the lens condition, clear the problem, and then turn off and on the power again. Initialize Error! message For the detailed setting method, refer to the "Display Operation Manual" at the end of this Operation Manual. How to detect the position of ZOOM Initialize operation How to detect the position ON (Auto) When the power is turned on, the lens automatically detects the position. Then, it returns to the position where it used to be when the power was turned on. OFF (Manual) Immediately after the power is turned on, the lens operates at a temporary position, and the position is corrected when the lens passes the specific position and the position is detected. How to detect the position of FOCUS Initialize operation Demand How to detect the position ON (Auto) Connected When the power is turned on, the lens automatically detects the position. Then, it returns to the position instructed by command from the demand. Not connected When the power is turned on, the lens automatically detects the position. Then, it returns to the position where it used to be when the power was turned on. Connected When the power is turned on, the lens automatically detects the position. Then, it returns to the position instructed by command from the demand. OFF (Manual) Not connected The lens does not automatically detect the position when the demand is not connected. When the demand is connected, the lens automatically detects the position. Then, it returns to the position instructed by command from the demand. Initialize Error! 2-2 Back Focus Adjustment If the relationship between the image plane of the zoom lens and that of the television camera is incorrect, the object goes out of focus when the lens is zoomed. Follow the steps below to adjust the back focus of the lens. 1 Select an object at an appropriate distance (XJ27x AF/XJ27x: 3 to 5 m, XJ100x AF/XJ100x/XJ95x Tele/ XJ95x/XJ86x AF/XJ80x/XJ76x/XJ60x: 10 to 15 m recommended). Use any object with sharp contrast to facilitate the adjustment work. 2 Set the lens to 1x [status without using an extender]. 3 Set the iris fully open. 4 Set the lens to the telephoto end. When position detection is failed: • The position signal sent from the lens to the camera and its indication on the information display will be incorrect. Notes • Iris is always initialized when powered on regardless of auto mode or manual mode. F.B. Adjusting Knob F.B. Lock Knob E7
