2.2 Replace a lens
Lens lever
The L40 lens mount and lens lever is designed to prevent damage to the lens board while providing an easy
and stable lens change procedure.
The lens lever, located at the bottom of the lens mount, slides between two positions, far left (default position
— unlocked) and far right (locked).
Always activate the projector shutter before attempting to remove or install a lens.
To do this, press the
shutter button on the keypad, or shutter Close on the remote, to activate the
shutter. The keypad button will illuminate red when the shutter is activated.
Press the
shutter button again, or shutter Open on the remote, to deactivate the shutter and
resume normal operation. The keypad button will illuminate white when the shutter is deactivated.
When changing from a lens with motorized Iris, zoom and focus positioning functionality, to a lens
without this functionality (e.g. from a EN 63 to a EN42 lens), it is recommended to power down, and
pull the AC cord. This is because the memory of the iris position will not be reset, but will show the
position in LCD or OSD for the lens that was removed. When rebooting the projector, the memory
will be reset.
The reverse scenario will happen when changing from a lens with no motorized positioning support,
to a lens with motorized positioning support. The iris position will not be showed with a correct
value. The functionality is still present, but the displayed value is not correct.
