2 PREPARATION
2-1 Initialize Operation
The following models require no initialization.
• UJ122x8.2B AF , UJ 122 x 8 . 2 B, UJ111x8.3B
• Models with the IESDA operation system
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.
The lens is automatically initialized on power-up.
ON [Auto]
(When in servo mode)
After the power is turned on, position detection is
performed when the lens passes the specific position
OFF [Manual]
(normally near the center) in the course of lens
operation.
For the detailed setting method, refer to the "Display
Operation Manual" .
How to detect the position of ZOOM
Initialize
How to detect the position
operation
When the power is turned on, the lens automatically
ON (Auto)
detects the position. Then, it returns to the position
where it used to be when the power was turned on.
Immediately after the power is turned on, the lens
operates at a temporary position, and the position is
OFF (Manual)
corrected when the lens passes the specific position
and the position is detected.

Demand
operation
When the power is turned on, the lens
automatically detects the position. Then,
Connected
it returns to the position instructed by
command from the demand.
ON (Auto)
When the power is turned on, the lens
Not
automatically detects the position. Then, it
connected
returns to the position where it used to be
when the power was turned on.
When the power is turned on, the lens
automatically detects the position. Then,
Connected
it returns to the position instructed by
command from the demand.
The lens does not automatically detect
OFF (Manual)
the position when the demand is
Not
not connected. When the demand is
connected
connected, the lens automatically detects
the position. Then, it returns to the position
instructed by command from the demand.
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.
* Default setting at factory: OFF
How to detect the position
• 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.
