Stain is leaking onto the counter.
Check all external reagent lines for visible signs of cracks
or loose fittings.
Make sure the drain outlet is not blocked.
Make sure the drain tube is securely attached to the
drain port and that the tubing is not cracked or
deformed.
Reagent leaks may indicate an internal problem (see
Section 7.3). See the Aerospray Service Manual, or
contact your dealer or ELITechGroup for further
assistance.
Error messages on the screen.
If the display shows Lid Not Shut: Verify that the lid is
fully closed and latched. If the Lid Not Shut indication
remains, contact ELITechGroup for assistance.
If the display shows Wrong Rotor after pressing Start:
Make sure the slide carousel is properly loaded on the
drive hub. In staining mode, the instrument detects
whether the staining carousel is present before
proceeding. In cytocentrifuge mode, the instrument will
stop if it senses the staining carousel. After verifying the
carousel is correctly loaded, press
Start
. If the display still
shows Wrong Rotor, there may be an internal problem.
Check for missing carousel magnets.
The microprocessor monitors carousel rotation during a
staining cycle. The display shows an error message if the
rotation is not within the specified range.
If the display shows Motor Drive Error: Check the stainer
bowl for interference: Turn the hub or carousel by hand;
it should turn freely.
Drive motor or electronic component malfunctions
require servicing of internal components. Contact your
dealer or ELITechGroup for assistance.
If the display shows Rotor Imbalance, make certain the
Cytopro rotor is balanced, or the staining carousel is
seated correctly on the hub.
