Pbaro sensor out
of range
Barometric Pressure
Sensor Out of Range
Low
Out of range barometric pressure data.
Range: 2163-4340 mV or 732-1196
cmH2O
The EC will use the entered
altitude setting to determine
the calculated barometric
pressure value.
• Calibrate the barometric sensor (refer to Section 8.7.4).
• Replace VMB (recalibrate barometric sensor).
Pexp sensor out
of range
Paw exp Sensor Out of
Range
High
Out of range Paw exp sensor data.
Range: 10-4095 mV
• Check/replace harness.
• Interchange Paux and Pexp connections. If Pexp alarm stops, replace Pexp sensor.
• If Pexp alarm continues, replace VMB.
Pexp sensor out
of range
Paw exp Zeroing Error
Low
Range for zero pressure: 631-96
8
mV
(counts)
If failed, vent uses previous
known good offset value for
Paw exp
• Verify Pexp port is not occluded.
• Zero Pexp pressure sensor.
• Check/replace zeroing valve.
• Check/replace harness.
• Interchange Paux and Pexp connections. If Pexp alarm stops, replace Pexp sensor.
• If Pexp alarm continues, replace VMB.
Pinsp sensor out
of range
Paw insp Sensor Out of
Range
High
Out of range Paw insp sensor
data >= 50 ms or Inspiratory Pressure
Zero Valve energized for >=1 second.
Range: 10-4095 mV
• Check/replace harness.
• Interchange Paux and Pinsp connections. If Pinsp alarm stops, replace Pinsp sensor.
• If Pinsp alarm continues, replace VCB
Pinsp sensor out
of range
Paw insp Zeroing Error
Low
Range for zero pressure: 631-96
8
mV
(counts)
If failed, vent uses previous
known good offset value for
Paw insp.
• Zero Pinsp pressure sensor.
• Check/replace zeroing valve.
• Check/replace harness.
• Interchange Paux and Pinsp connections. If Pinsp alarm stops, replace Pinsp sensor.
• If Pinsp alarm continues, replace VCB.
PO2 sensor out of
range
O2 Supply Pressure
Sensor Out of Range
Low
Out of range O2 supply pressure
sensor data.
Range is 195 to 4760 mV
• Check O2 supply.
• Disconnect sensor and verify output is zero gage pressure.
• Interchange harness connections on both supply pressure sensors.
• If alarm follows the sensor, check sensor connector terminals. Replace supply pressure sensor if necessary.
• If not, then check/replace harness.
• If not harness, then replace VMB
