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.
See Electronic Failure later in this table.
The stainer fails to spray reagent during
a staining cycle and/or continues to run
after the cycle should be complete.
To allow programmed staining of partial loads, the stainer
monitors the position of the carousel as it rotates in the bowl.
In normal operation, stain is sprayed only in the correct
position. This causes the actual cycle time to vary, depending
on the position of the carousel at the beginning of the cycle.
However, if the cycle continues for an abnormally long period,
or if the bar graph and percentage complete icon do not
change after 1 minute, it may indicate an electronic problem
or an internal problem. To determine this, press
Stop
.
If the cycle stops: this indicates a problem with the carousel
position sensor. Consult the Aerospray Service Manual or
contact your dealer or ELITechGroup for assistance.
If the cycle continues: this indicates an
electronic problem (see below).
