5.5Controlling the iris (master value: Iris)

If the aperture of the lens (iris) is to be controlled by the WRC-1, a lens motor CLM-2 must be mounted on the camera and connected to the UMC-1/URM-1.

Note:

The iris can only be adjusted using CLM-2 motors.

 

If a CLM-1 motor is used the warning ‘NO IRIS’

 

is displayed.

When switching on the WRC-1, the IRIS sliding switch ➪ photo is used to determine whether the WRC-1 (‘IRIS ON’) or another unit (e.g. a WFU-1) (‘IRIS OFF’) controls the connected iris motor.

•The IRIS sliding switch must be set to ‘ON’ before turning on the WRC-1.

If the IRIS sliding switch is not set to ‘ON’ and an operating mode is selected, which requires an iris motor, the warning ‘NO IRIS’ is displayed. This warning is also displayed if the IRIS sliding switch is set to ‘ON’ although a CLM-2 motor has not yet been connected. In this case the CLM-2 motor must be connected to the IRIS socket on the UMC-1.
