TRA Operator’s Manual 20077/021 US 10-11
Figure 10-7 Ready Screen (PRP2)
For a detailed explanation of the
Ready Screen, read “Ready
Screen” on page 5-38.
1. Before beginning a cycle, select the desired protocol and operating mode (as explained in
“Selecting the Active Protocol and Operating Mode” on page 10-8).
2. Touch the Start button to begin the Fill phase.
The Fill Phase
When the Fill phase is started (by touching the Start button from the Ready Screen), the Processing
Screen is displayed on the touch screen.
Before starting the procedure, the operator will be prompted by a message in the message area to
check that the connection line between . . .
• the bowl and the collection bag is open
• the bowl and the waste bag is closed
• the bowl and the second collection bag is closed.
3. Perform the requested action:
◊ If processing with the PPP or PRP2 protocols, close the PRP (orange clamp) and waste bag
(white clamp) lines. Open the PPP (yellow clamp) line. Then touch the Play button.
◊ If processing with the PRP1 protocol, close the PPP (yellow clamp) and waste bag (white
clamp) lines. Open the PRP (orange clamp) line. Then touch the Play button.
The fill clamp opens and the centrifuge begins accelerating. Once the centrifuge reaches its target
speed, the pump will begin rotating and filling the bowl with blood from the whole-blood bag.
The Fill phase, like all processing phases, is monitored and controlled from the processing displet of
the Processing Screen (see Figure 10-8).
CAUTION
Make sure to open a blood collection (plasma) bag flow path before closing
the waste bag port. Failure to do so may result in fluid leaking from the
centrifuge bowl seal.
