Start Pumps Substate
This substate commands the pumps on individually to minimize voltage spikes. When all pumps have
reached their commanded speed (± 5 mL/min), the Trima Accel system advances to the Lower Cassette
substate.

Lower Cassette Substate
In this substate the cassette is commanded down and the lower optical switch is checked to verify that the
cassette achieves the loaded position. If this does not occur within 15 seconds, the “Cassette Error” alarm
generates.
The access pressure sensor is auto-zeroed at this point.

Cassette ID Substate
During this substate the RBC detector checks the cassette type to make sure that it is the proper cassette
for the chosen collection procedure. If the cassette does not match the procedure, an alarm is generated.
If the tubing set cannot be identified, but is within a valid range, a screen displays that allows the operator
to choose the correct tubing set or load a new one. For white stamp cassettes only: During this substate
the Trima Accel system begins calibration of the red and green reflection strengths of the RBC detector
