* DRBC tubing sets
Exit Condition When 8 mL is processed by inlet pump.
Prime Vent (Vent Air) Substate
This substate occurs in platelet collection procedures only. The centrifuge and pumps remain at their
previous speeds and the platelet valve moves to the collect position to remove air from the channel. After
a version-specific volume of platelet have been pumped, the Trima Accel system advances to
the Ramp Centrifuge substate.

Ramp Centrifuge Substate
The centrifuge is commanded to its final calculated speed (usually 3000 rpm). If it cannot make it to its
final speed in 2 minutes, a centrifuge hardware alarm is generated. The platelet valve is commanded back
to the return position while the pumps and centrifuge remain at their previous speeds. When the
machine goes from the first draw cycle to the first return cycle the Trima Accel system advances to the
Remove Channel Air substate.
