Manual lens installed.

Replace the manual lens with a motorized lens.

The activated lens file does not correspond with the lens mounted on the projector.

Activate a lens file which does correspond with the mounted lens or mount an other lens which corresponds with the lens file you want to activate.

Corrupt lens file.

Delete the lens file and program correct lens type into communicator under Advanced/lens parameters and recreate a new lens file. Tip: perform a “Lens Homing” before creating a new lens file. Otherwise, if the lens is removed the existing lens file becomes useless. Setup all new lens files away from the maximum limitation of the lens zoom. It is possible that the lens file was originally created at the maximum or minimum zoom capabilities of the lens zoom.

The final lens position lays very close to the mechanical limits which disable the motorized lens position.

Position the lens manually, or reposition the projector so that the lens position lies further away from the mechanical limits, or try to use another lens which range is more suitable. Setup all new lens files away from the maximum limitation of the lens zoom. It is possible that lens file was originally created at the maximum or minimum zoom capabilities of the lens zoom. Program correct lens type into communicator under Advanced/lens parameters and recreate the lens files.

Disconnected wire units (reference 1 image "Lens connections") of the zoom motor of the motorized lens.

Remove the front cover of the projector and check if all wire units at the left bottom of the lens holder are connected.

Disconnected wire unit, of the lens zoom/shift signals, from the Signal Backplane.

Remove the front cover and front dust filter from the projector and check if the wire unit (reference 4 image "Lens connections") is inserted in the Signal Backplane (white plug behind blue wires).
