Prime Channel 2 Substate
The plasma and platelet pumps are commanded to zero while the AC and inlet pump speeds are
maintained until a version-specific predetermined inlet volume has been pumped. The Trima Accel
system then advances to the Prime Channel 3 substate.

Prime Channel 3 Substate
The inlet pump continues to run at the speed from the previous substate (or Qin, whichever is less), the
AC ratio changes to the ratio calculated for the collection procedure, and the AC pump speed changes
accordingly. After a version-specific inlet volume has been pumped, the Trima Accel system advances to
the Prime Channel 4 substate.

Prime Channel 4 Substate
The inlet pump speed increases again to a version-specific maximum speed and the AC pump speed
changes accordingly. The plasma and platelet pumps are commanded to version-specific speeds. The
Trima Accel system begins checking for fluid at the upper reservoir sensor and executes return cycles as
necessary. After a version-specific inlet volume has been pumped, the Trima Accel system advances to
the Prime Vent substate.
