Air temp high
Flow Wave:
O2 only
Temp High High
Total flow sensor temperature > 48°C Switch to 100% O2.
Air is turned off regardless of
other alarm conditions (for
example, O2 Supply Low).
When the condition clears, the
vent changes back to previous
known good set O2 mixture.
• Check inlet air temperature.
• Use Service App to check temperatures of air and total flow sensors.
• If inlet air temp is NOT high, and if temp from total flow sensor reports more than 9°C higher than the air
sensor, replace Total Flow Sensor.
• With a air flow of approximately 10 l/min, verify air and total flows are within 10% of each other.
Air temp sensor
error Air Temperature Sensor
Failure Low
Out of range air temperature sensor
data (range is 0-60 degrees C). Use total flow temperature for
all air flow sensor calculations,
including alarms.
If total flow sensor
temperature not available, use
50°C.
• Check inlet air 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 air and total flow sensors. Air flow sensor and total flow sensor shall not differ by more than 9°C.
• Replace sensors.
Backup audio
failure Backup Buzzer POST Medium Current to buzzer indicates audio is not
sounding.
This alarm is logged at start-
up and can be de-escalated
but cannot be cleared from
the screen.
The primary and backup alarm
audio sounds upon every
power-up of the EC system.
• Check harness connection between PMB/On-Standby switch.
• Verify buzzer current with voltage measurement at TP15 on VCB. If voltage IS NOT present, replace PMB. If
voltage IS present, replace VCB.
Backup mode
active Backup Mode Active Medium Spontaneous breathing is insufficient
or Display Unit failure.
System goes into Backup Ventilation
mode.
Uses PCV mode and preset
settings (customer
configurable).
• Ensure the patient’s spontaneous breathing and ventilatory support is adequate. This alarm could be
triggered by user errors regarding patient ventilation requirements. See URM for details.
• Check error log for communication errors or DU errors.
