Pre Rinseback (Prepare for Rinseback) Substate
This substate occurs in both platelet/plasma/RBC procedures and DRBC procedures. All valves move to
the return position and all pumps are commanded to zero. When these actions successfully complete,
the Trima Accel system advances to the Blood Rinseback state.

Blood Run Recovery Substates
The Blood Run state contains eleven recovery substates. Recovery substates interrupt the procedure and
suspend the procedure time clock.
When the recovery routine completes, the Trima Accel system returns to the procedure substate that it
was in prior to recovery. These recovery substates can occur at any time during the Blood Run state.
Only one recovery substate happens at a time. Descriptions of the recovery substates follow.
RBC Spillover (Spillover Recovery) Substate
Spillover recovery can be entered via a command from the operator (by pressing the
Spillover
button on
the Adjust screen) or automatically when detected by the RBC detector. This substate triggers the WBC
Chamber Purge substate followed by the Clear Line substate (see the description for these recovery
substates on next page). At the end of spillover recovery, the RBC detector checks for the presence of a
spillover and regenerates the recovery procedure if a spillover persists.
Pumps Pause (Pause Recovery) Substate
This recovery occurs when the pumps are paused for more than 6 seconds. After the inlet pump processes
a predetermined inlet volume, the pumps return to their original collection values and the Trima Accel
system returns to the previous blood run substate.
Air Block (Air Block Recovery) Substate
This recovery is initiated when the operator presses the
Air in Plasma Line
button on the Adjust screen.
The centrifuge speed lowers to a predetermined speed, all valves close, and the pump speeds lower to
remove the air block. The plasma pump runs at a predetermined speed, maintaining chamber flow, until
a predetermined volume of plasma has been pumped. The system then transitions to the Centrifuge
Stop substate.
