Negative Press Test (Negative Pressure Test) Substate
This test commands the inlet pump until the access pressure sensor reading is less than a version-specific
predetermined amount. If the pressure is reached before the exit condition, the Trima Accel system
advances to the Negative Press Relief substate. If the test fails, pressing the
Continue
button returns to the
Press Inlet Line substate. Pressing the
End Run
button unloads the cassette and proceeds to the beginning
of the Startup Tests state.

Negative Press Relief (Negative Pressure Relief) Substate
This final disposable test substate commands a pump until the access pressure sensor reading is greater
than a version-specific predetermined amount. If this does not occur before the exit condition, an alarm
is generated. When this pressure is achieved, the disposable tests are complete, and the Trima Accel
system advances to the AC Connected state.
