main processor board does not recognize a mainstream daughter board when
mainstream mode is selected.
Action Check if the mainstream daughter board is present. If so, the mainstream daughter
board may be not functioning correctly.
80h, Pump Fault (sidestream only)
High flow and high vacuum conditions are detected in the pneumatics.
81h, Unexpected Reverse Flow (sidestream only)
An unexpected reverse flow condition in the pneumatics, indicated by non-zero initial values,
turns the pump off.
Action Check the Water trap or cannula for improper connection to a vacuum source. Check
the exhaust tubing for improper connection to a positive pressure source. Do a hard reset.
82h, Unexpected Forward Flow (sidestream only)
An unexpected forward flow condition in the pneumatics, indicated by non-zero initial values,
turns the pump off.
• Action Check the Water trap or cannula for improper connection to a positive pressure
source. Check the exhaust tubing for improper connection to a vacuum source. Do a hard
reset.
84h, Barometric Pressure Too High
Barometric pressure transducer reading is greater than the upper barometric limit.
• Action Check that the host system is operating at barometric pressures less than 790
mmHg (1,150 ft below sea level). If so, the transducer may be faulty.
85h, Barometric Pressure Too Low
Barometric pressure transducer reading is less than the lower barometric limit.
• Action Check that the host system is operating at barometric pressures greater than 408
mmHg (15,000 ft above sea level). If so, the transducer may be faulty.
