High Pressure O2 Leak Test
Complete
Vent engine high O2 pressure leak test passed.
None
High Pressure O2 Leak Test
Fail
Vent engine high O2 pressure leak test failed
because measured leak was too high.
Refer to Section Section 5.2.6
High Pressure: Aborted
The Checkout step in progress was aborted due
to high pressure.
1. Verify breathing circuit is properly connected
for checkout.
2. Verify proper flow and exhalation valve
calibration; recal if necessary.
Insp flow below target:
>Target = Value1
>Insp = Value2
Flow cannot be controlled down to the target
flow because the measured flow is already
lower than the target flow.
1. Check for disconnected breathing circuit
during Checkout.
2. Verify proper flow valve calibration; recal if
necessary.
Insp Span Counts: Value
Inspiratory pressure sensor DAC counts that
correspond to 100 cmH2O.
(range: 3026 to 3589)
None
lInspFlowAccumulator=
Value1, _jj=
Value2
Intermediate values in low pressure leak check
compliance calculation.
None; for information only.
Low Air Pressure:
value
Air supply pressure < 30 psig
Verify proper gas supply.
Low Exp Pressure: Value1
,
Value
2
During exh valve cal, the pressure dropped
more than 1.25 cmH2O in 4 msec.
Value1
= Current measured pressure
(cmH2Ox100).
Value2 =
Current calibration point
Check for disconnected breathing circuit during
calibration.
Low Max Flow: Value
FCV - Indicator that system will use the
degraded wall supply routine for FCV
calibration.
Check gas supply source to see if it is too weak
or restricted if this causes problems.
Low O2 Pressure: Value
O2 supply pressure < 30 psig
Verify proper gas supply.
Low Pres Leak Test Fail
(Baro)
Vent engine low pressure leak test failed
because of invalid (low) barometric pressure
reading.
1. Verify correct altitude setting.
2. If the setting is correct, calibrate the
barometric sensor.
3. Replace Vent Monitor Board (VMB)
Low Pressure Leak Chk
Breathing circuit leak check in progress.
None
Low Pressure Leak Chk
Complete
Breathing circuit leak check passed.
None
Low Pressure Leak Chk Fail
Breathing circuit leak check failed.
See previous message in status log cause of
failure.
Low Pressure Leak Test
Vent engine low pressure leak test in progress.
