No gas supply
pressure No Supply Pressure High
O2 supply pressure and air supply
pressure < 24.3 psi for more than 0.5
seconds Continue 100% gas flow of
whichever gas has the higher
pressure value at the onset of
the alarm; if both are equal,
use 100% O2.
• Check O2 and Air supply pressures.
• Check/replace harness between sensor and VMB.
• Check error log for reference voltage errors.
• Check/replace VMB.
O2 sensor failure O2 Sensor Fail Medium
Out of range O2 sensor (Paracube)
data greater than 103% or
communication error
• Calibrate O2 sensor with Checkout (ensure both Air and O2 gas supply are connected).
• Calibrate O2 sensor with Service App (ensure both Air and O2 gas supply are connected).
• Verify O2 Concentration sensor voltage error is not present in error log.
• Check/replace harness.
• Check/replace O2 sensor.
• Check/replace VMB.
O2 supply
pressure high O2 Supply Pres High Low
O2 supply pressure > 95 psi for more
than 0.5 seconds
• 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, replace supply pressure sensor.
• If not, check/replace harness.
• If not harness, check/replace VMB.
O2 supply
pressure low
Flow Wave:
Air only
O2 Supply Pres Low Medium
O2 supply pressure < 24.3 psi for more
than 0.5 seconds Latched
De-escalatable
Go to 100% Air.
• Check O2 supply.
• Disconnect sensor and verify output is zero gauge 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, check/replace harness.
• If not harness, replace VMB.
O2 temp sensor
error O2 Temperature Sensor
Failure Low
Out of range O2 temperature sensor
data. (range is 0-60 degrees C)
• Check inlet O2 temperature.
• If
comm. Failure
alarm is also active, check harness connections.
• With gas supplies disconnected and system temperature stabilized, use Service App to check temperatures
of O2 and total flow sensors. O2 flow sensor and total flow sensor shall not differ by more than 9°C.
• Replace sensors.
