Power Fail Recovery State
The PFR state allows the Trima Accel system to restore data if a power failure occurs during a procedure.
This state begins with a handshake across domain boundaries between control and safety computers.
The Trima Accel system tries to restore data (in the power fail save file) from a previous procedure if there
is any valid data. If there is valid data, the Trima Accel system performs the power tests that are normally
performed in the Startup Tests state and then restores the previous data. After restoring the data, the
Trima Accel system allows the operator a choice to continue with or discontinue the collection
procedure. The rules for continuation from a power fail situation follow:
•
If the power failure occurs during the Startup Tests state through the AC Prime, Rinseback, or
Donor Disconnect states, recovery is not allowed. The operator must unload the set.
• If the power failure occurs during the Donor Connected state, the operator can continue or end the
collection procedure.
• If the power failure occurs in the return cycle during the Blood Prime and Blood Run system states,
the operator can continue, rinseback, or end the collection procedure with no time restraint.
• If the power failure occurs during the draw cycle of the Blood Run or Blood Prime states, the
operator can continue, rinseback, or end the collection procedure if the PFR screen is restored
within 9.5 minutes. If power is not restored within 9.5 minutes, the operator can only end the
collection procedure.
• If the power failure occurs during the Rinseback state, the operator can rinseback or end the
collection procedure.
Successful completion of PFR state results in the following conditions and actions.
Termination Condition
Trima Accel
System
Condition
Trima Accel System Action
PFR data successfully
saved and restored if valid. Pause. If there is no valid PFR data, the Trima Accel system proceeds
automatically to the startup tests in the Startup Tests state. If there
is valid PFR data, the Trima Accel system proceeds to the power
tests in the Startup Tests state.
Startup Tests State
The Startup Tests state performs the Trima Accel system's mandatory startup tests.
This state follows the Power Fail Recovery (PFR) state. It contains tasks that start in this state and
continue until the Donor Connected state. The Startup Test state ends when all tests are successfully
completed.
The startup tests are executed before a disposable tubing set is loaded and before the donor is connected.
These tests ensure that the Trima Accel system is operational, that the critical safety features are in place,
and that computer redundancy is functioning. During power fail recovery situations only some of the
tests are performed to ensure safety of the already-connected donor. Startup tests include the following
activities:
•
Test if the safety system can disable power to pumps and centrifuge.
• Test the cassette position function (up and down) at both the control and safety computers.
