◊ If operating in Manual mode with the RBC detector disabled: the buffy coat will not be
detected automatically. When you have determined that enough blood has been pumped
into the bowl, touch the Empty phase button in the button bar to advance to the Empty
phase.
When processing with the PRP protocols, the next phase of operation is the Spill phase:
◊ When operating in Automatic mode, the pump is stopped and processing is advanced to the
Spill phase automatically once the buffy coat is detected. No intervention is necessary in
this mode.
◊ If operating in Manual mode with the RBC detector enabled: a message will be displayed in
the message area and the pump will stop. Touch the Spill phase button in the button bar to
advance to the Spill phase. To continue in the Fill phase, touch the Play button.
◊ If operating in Manual mode with the RBC detector disabled: the buffy coat will not be
detected automatically. When you have determined that enough blood has been pumped
into the bowl, touch the Spill phase button in the button bar to advance to the Spill phase.
Note: It is possible to manually advance phases while operating in the Automatic mode. Touching
the Pause button from a Processing Screen will stop the pump and display phase buttons in the button
bar. The operator may touch the appropriate phase button (Spill or Empty) to switch to that phase, or
touch the Play button to continue processing in the current phase.
The Spill Phase
Note: The Spill phase may be activated from the Fill phase only when the centrifuge has reached its
full speed, or when the pump is rotating.
The Spill phase is only entered when processing with the PRP1 or PRP2 protocols. It consists of two
sub-phases: during the first (Spill PPP), an additional volume of plasma is collected; during the second
(Spill PRP), the concentrated platelets are collected.
The processing displet changes to reflect that the Spill phase is in progress (see Figure 10-9).
Depending on which sub-phase is active, either the text “Spill PPP” or “Spill PRP” is displayed in the
title bar of the processing displet.

For a detailed explanation of the
Spill phase screen, read “Spill
Screen” on page 10-25.
During the Spill PPP sub-phase, the volume of PPP spilled into the collection bag is displayed on the
screen and constantly updated by the system’s software. The desired total volume of PPP to spill, as
well as the spill speed, can be adjusted from the processing displet. The desired volume of PRP to spill
during the Spill PRP sub-phase may also be set from processing displet during this sub-phase.
