MSS Connect Substate
This substate waits for the operator to confirm that PAS and/or RAS storage solutions are connected.
This state calculates the correct amount of storage solution to be metered to the product based on the
actual collected volume and the Plasma-Percent carryover. This substate also calculates the estimated
storage solution used for the MSS run (prime, addition, and purging) and sends it to the GUI task. The
substate will exit upon receiving message to continue from the GUI task.

MSS Prime Substate
This substate primes the system with storage solution. The Trima Accel system monitors the APS during
these substates. If the APS raises above the configured value, the state will pause and run the inlet pump
to relieve the pressure. The MSS Prime substate consists of five subordinate substates.
Reservoir Setup 2
This substate empties the reservoir. The return pump will run until the lower-level sensor detects air.
