About

The illumination Engine contains the Relay Tube Assy (Lens), Motorized Iris Assy, Folding Mirror assembly
and CLO sensor (Constant Light Output).

GP7 Iris assy and Relay Tube assy can be removed without removing illumination engine.

Adjustable mirror and CLO can only be accessed after removing the complete engine core, including lens
shift.

Preparations

To facilitate the operations in the next topics, it is recommended to remove the optics fan.

Release the two screws indicated, disconnect the cable and remove the fan.
