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 correspond with the lens file you want to activate.

Corrupt lens file.

Delete all current lens files and create new lens files. Note that each time the lens is removed new lens files has to be created. 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.

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.
