Error Log Entry
Action/Troubleshooting
FLOW ATTAINMENT
FAILURE CH1
Replace the O2 Proportional Valve.
Replace the Mixer.
FLOW MANIFOLD
EEPROM FAILURE
Check all connections of the Flow Meter Block to the ADB.
Cycle power.
If the problem persists replace and retest, in the following order (Also see Section 7.10.):
• Flowmeter Block
• ADB
FLOW SENSOR CAL
ERROR
See associated Errors. i.e. "EXP FLOW SENSOR CAL ERROR" or "AIRWAY SENSOR CAL ERROR".
FLOW VALVE
CURRENT FAILURE
In the Service Software / Vent Flow & Pressure Diagnosis, increase the Flow Valve counts and view the
Flow Valve Current mA and Counts.
FLOW VALVE DAC
FAILURE
In the Service Software / Vent Flow & Pressure Diagnosis, increase the Flow Valve counts and view the
Flow Valve Current mA and Counts.

Alarm Text Condition (Basic info)
Indicates the commanded
flow through the O2 Gas
channel does not match the
measured flow via the flow
sensor and the differential
pressure transducers.
Vaporizer Failure Cassette pressure and flow
meter calibration data
EEPROM read error or
cassette pressure and flow
meter hardware revision data
EEPROM read error or
software compatibility failure.
Calibrate flow sensors Insp or Exp flow sensor or the
airway or manifold pressure
sensor zero offset out of range
(flow calibration failure)
Indicates the current
feedback from the Insp Flow
Valve was incorrect for
seven consecutive readings.
Indicates the current
feedback from the Insp Flow
Valve was incorrect for
