Code 5232: “lens horizontal shift position - requested target not reached” (Warning)
Situation Solution
The activated lens fi le does not
correspond with the lens mounted
on the projector.
Activate a lens fi le which does correspond with the mounted lens or mount an other lens
which correspond with the lens fi le you want to activate.
Corrupt lens fi le. Delete all current lens fi les and create new lens fi les. Note that each time the lens
is removed new lens fi les has to be created. Setup all new lens fi les away from the
maximum limitation of the lens zoom. It is possible that lens fi le 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
fi les.
The fi nal 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 lays further
away from the mechanical limits, or try to use another lens which range is more suitable.
