Diagnostic
Code Code Description
1014 POST timer/24V failure: system has
reset 3 times within the first 30
seconds of operation. Once this code
occurs, it recurs at every power up or
reset until the ventilator enters
diagnostic mode.
2xxx: Failures During Short Self Test (SST)
2000 SST passed.
2100 Cancelled by user.
2106 Patient circuit leak.
Patient circuit test (test 11): this
code indicates that the ventilator
could not pressurize the tubing
circuit to 50 cmH
air flow and the safety and
exhalation valves closed.
2107 Low inhalation pressure.
Patient circuit test (test 11): this
code indicates that circuit pressure
dropped from 50 cmH
cmH O after exactly 100 ms.
2
2110 Check valve 3 (CV3) leak.
Patient circuit test (test 11): the
circuit is pressurized to 50 cmH
with the exhalation valve closed,
then the safety valve opens. After
two seconds, circuit pressure should
not drop below 35 cmH
code indicates that circuit pressure
was <35 cmH

Review the diagnostic log: the code in
memory before or after the 1014
occurrence indicates the root cause.
If this code is not 4, 7xxx, or 8001:
1. Replace power supply.
2. Replace main PCB.
3. Replace CPU PCB.
No action required.
No action required.
1. Remove inspiratory bacteria filter and
external oxygen sensor and try
another patient circuit.
2. Block outlet of exhalation flow sensor
while running leak test. If leak stops,
O with a 5 LPM
replace exhalation valve.

3. Verify that connection between the
oxygen flow sensor and oxygen valve
is tight.
1. Check for patient circuit leaks.
2. Verify that o-ring is present in
external oxygen sensor or bypass
oxygen sensor.
O to <45
3. Check inhalation pressure transducer
2
(Chapter 5).
4. Check the connection between the
inspiratory manifold and inspiratory
autozero solenoid.
5. Check for kinks or cuts in the tube
between inhalation autozero solenoid
and inhalation pressure sensor.
6. Replace sensor PCB.
7. Replace three-station solenoid.
1. Check for patient circuit leaks.
2. Verify that o-ring is present in
external oxygen sensor or bypass
O
oxygen sensor.
2
3. Verify that CV3 is undamaged and in
12:00 position.
4. Check CV3 (Chapter 5). Replace as
O. This
2 necessary.
5. Check tubing from inspiratory
O.
