provide maximum separation between the filter surface and end of the tool that is used to
turn the retaining ring.
Finally, install the threaded retaining ring. DO NOT OVER TIGHTEN THE RETAINING

Loading filters into the filter cups on the filter wheel follows the same procedure as described
above for loading filters into filter holders. There is, however, the additional complication of
working through the filter wheel housing. To gain access to the filter cups on the wheel,
unscrew the access plug from the loading port on the motor housing (i.e., the motor side of
the filter wheel). A large coin or other suitable implement can be used to remove the plug.
Once removed, the retaining ring in the underlying filter cup is accessible through that port.
To align the filter position you wish to load with the loading port, it is easiest to use the
controller to identify and position the filter cups. To begin, connect the Filter Wheel to the
controller (see the FIRST TIME USE chapter for a brief description of the principles of
operation). When you first turn on the controller, the Filter Wheel will “HOME” itself,
aligning the “0” filter position with the Optical Port and filter position #5 with the Loading
Port. The filter currently in the Loading Port is five positions removed from the one
indicated by the controller display (i.e., the one at the OPTICAL PORT). This relationship
between the filter position indicated by the controller and the filter position at the
LOADING PORT is illustrated in Figure 2-8.
