Evacuate Bags Substate
This substate removes air from the product bags. The return pump runs until a predetermined volume
has been pumped (version specific). If the access pressure exceeds the alarm limit during this test, an
alarm is generated and the Trima Accel system reverts to the previous substate. If the test passes, the
Trima Accel system advances to the Lower Notification substate.
