Action/Troubleshooting
FLOW VERIFICATION
FAILURE (dP) CH1
Perform the Mixer zero.
Replace Mixer.
FRONT PANEL COM
FAIL
Reboot system. If problem continues, replace Display Controller Board.
GAS INLET VALVE
BOOTUP TEST FAIL
1. Check GIV solenoid connection.
2. Replace GIV.
3. Rebuild the GIV components.
4. Replace VIB.
INFLOW CHECK VALVE
FAILURE
Replace Inflow check valve.
(Also see Section 7.10.)

INFLOW OUTFLOW
CROSSCHECK FAILURE
RECOVERABLE
Check eVap and cassettes used with the machine for leaks.
Replace and retest in the following order (Also see Section 7.10.):
• Zero Valve (Inflow or Outflow depending on Vaporizer Test results).
• Flowmeter Block
• ADB
INSP FLOW SENSOR
CAL ERROR
In the Service Software / Vent Flow and Pressure Diagnostics, verify the Inspiratory Pressure counts is
2050 ± 250.
Disconnect the Black and White in-line connectors. If the counts return within specified range, check for
occlusions in the Bulkhead harness.
If the counts do not return within the specified range, replace the VIB.
M1046983 04/08
Alarm Text Condition (Basic info)
Indicates the commanded
flow through the O2 Gas
Channel and the flow
measured by the Hot-wire
anemometer agrees but the
flow as measured by the
pressure transducers does
not agree.
Display panel controls Key pad controller fails to
failure send "life tick" for greater
than 10 Sec.
Vent Fail. Monitoring Boot-up test failed.
Only
Vaporizer Failure Negative flow in the cassette
inflow limb greater than limit.
Vaporizer Failure Output concentration
measured by the output and
input flowmeter disagree by
more than limit.
Calibrate flow sensors Insp Flow Sensor zero offset
out of range.
