5. Installation and commissioning Instructions

• Make sure the power is removed before the installation.

• To apply power:

First connect the low voltage (DC12V or AC24V). Then plug the AC adapter to AC outlets to avoid an

improper reset from power jitters and damage from the surge voltage when no load.

5.1. Attaching the lens

• Remove the Dust Protection cap from the lens mount

• Screw the lens onto the camera without using force

5.2. Setting the back focus lock

The back focus is the distance between the lens support on the camera and the image sensor. Optimum

focus is only possible when the correct distance is set. It may be necessary to set the back focus in

individual cases due to production tolerances of the lens. The iris of the lens must be open as wide as

possible. (Smallest F value) to set the back focus. For lenses with automatic iris control, you will require a

ND filter (gray filter) to prevent the iris from closing in bright light.

Setting for lenses with a fixed focal distance:

If the focus cannot be set exactly by turning the focus ring (lens), please proceed as follows;

1. Point the camera at an object with sufficient contrast. The distance to the object should be longer than

1,000 x the focal distance.

2. Open the iris on the lens

3. Set the focus of lens so that the distance at the lens is close to infinity but not to exact infinity position.

4. Loosen Back focus Adjustment Lock: Screw one~two turns on the camera with industrial “+” driver
