Successful completion of the Disposable Tests state results in the following conditions and actions.
Exit Condition
Trima Accel System
Condition
Trima Accel System Action
All disposable tests have
passed. Pause. The Trima Accel system prompts the operator to
connect the AC line.
Disposable Tests Substates
The disposable tests are a sequential series of automated tests designed to ensure that the tubing set is
properly loaded and functioning correctly. These tests also check the occlusions in the AC, inlet, and
return pumps and the function of the access pressure sensor.
Close Valves (Move Valves to Return Position) Substate
This substate commands the platelet, plasma, and RBC valves to the return position. If they do not
achieve the return position, an alarm is generated. When all valves reach the return position, the Trima
Accel system advances to the Press Inlet Line substate.
