20077/021 US XTRA Operator’s Manual
User Interface
When the waste line color indicator is enabled, the information gathered by the indicator is presented
to the operator during processing through the user interface in two ways:
• The Wash phase screen will display a waste line color indicator dot which changes color from red
to yellow to green with the color of the waste line (red indicating an opaque color; green
indicating a transparent color).
• The tally table displayed in the Tally tab of the Menu Screen and in the End of Case Screen will
show the waste line color indicator dot (red, yellow, or green) for each cycle of the case.
Warnings Related to Waste Line Color Indicator
If the waste line color indicator is enabled, then the “Reached” and “Not reached” quality warnings
may also be enabled.
“Not reached” Warning
When the “Not reached” quality warning is enabled, and if the minimum wash quality (a pre-defined
combination of minimum supernatant removal and waste line color) has not
been reached by the time
the Wash phase has completed, the system will issue the following warning and continue in the Wash
phase: “Minimum wash quality might be not reached yet”.
The machine will then continue in the Wash phase transferring additional wash solution by steps of
100 ml until the contaminants removal % is satisfactory, or until the additional volume of saline
solution is equal to max 50% of the currently set wash volume.
Touch the Empty button to manually switch to the Empty phase without further washing.
“Reached” Warning
If the “Reached” quality warning is enabled, and if sufficient wash quality (a pre-defined combination
of minimum supernatant removal and waste line color) is detected before the Wash phase has
completed, the system will issue the following warning and the operator may switch directly to the
Empty phase: “Minimum wash quality might be already reached”. The Wash phase continues
automatically until the operator manually switches to the empty phase or until the pre-set volume is
reached.
Touch the Empty button switch to the Empty phase without further washing.
CAUTION
It is recommended that the operator manually monitors the color of the fluid
in the waste line before proceeding with the Empty phase.
