1. Press the [START LOADER] key in the RUN menu. Based on which condition
exists (refer to the Sample Loader Description, Soft Keys subsection), either
the Sample Loader will be activated or a submenu will be displayed.
2. If the submenu is displayed, press either [RESUME LOADER] or [RESET
LOADER] (refer to the Sample Loader Description, Soft Keys subsection for
a discussion of when to use each key).
3. Racks are moved in sequential order from the load side, through the Mixing
and Aspiration Stations to the unload side (refer to Figure 13.8).
4. For sample mixing and aspiration to occur, the sensors must detect a tube in
the rack. The Sample Loader automatically stops after the last rack is
processed and no more racks are detected on the load side.
5. When the tube is at the Vent/Aspiration Station, the Spinner positions the
tube vertically in the rack, spins the tube for bar code reading, and holds the
tube while it is vented and the sample aspirated. Proper positioning is
necessary for the tube stopper to be pierced in the center.
6. The Tower Cover on the CELL-DYN 3200SL model fits over the Mixing
Station and Bar Code Reader on the loader. This cover prevents aerosol
contamination and exposure to the needle while the Sample Loader is
processing specimens.
NOTE: The Sample Loader has an interlock switch that prevents operation
when the Tower Cover is not in place. If the Tower Cover is
removed during Sample Loader operation, processing is
immediately halted. For an orderly stop, the operator must press the
[STOP LOADER] key and wait for the Sample Loader and Analyzer
to stop processing before lifting or removing the cover. Lifting the
cover while the Sample Loader is operating causes an immediate
Emergency Stop condition. The entire system must be re-initialized.
