Failure Description Possible Cause Recommended Action
[00002000] is
displayed The resolution of the expiratory
flow sensor is incorrect.
1. Check the sampling line connection
and tightness.
2. Check the gas supply pressure.
3. Check the configuration of the
calibration device.
4. Troubleshoot the sensor and valve
fault using the valve diagnosis tool.
For details, see section 5.4.
5. Replace the corresponding flow
sensor on the circuit.
6. Replace the VCM.
[00004000] is
displayed The resolution of the ventilator
flow sensor is incorrect.
1. Check whether the sampling line is
connected correctly.
2. Replace the ventilator flow sensor.
3. Replace the VCM.
[00008000] is
displayed The valve output flow speed is
insufficient.
1. Check whether the gas supply
volume is sufficient for the whole
calibration process.
2. Check whether the maximum
output flow on the valve is greater
than 90 L/min. If not, replace the
inspiratory valve.
[00010000] is
displayed The valve resolution is
insufficient.
1. Check whether the gas supply
volume is sufficient for the whole
calibration process.
2. Check whether the calibration
device works properly.
3. Replace the inspiratory valve.
[00020000] is
displayed The flow change is not
unidirectional.
1. Check whether the tubes are
connected correctly based on the
instructions.
2. Check whether the gas supply
volume is sufficient for the whole
calibration process.
3. Check whether the calibration
device works properly.
[00040000] is
displayed
The communication connection
to the calibration device is
interrupted.
1. Check the communication
connection between the calibration
device and the anesthesia machine, or
reconnect the calibration device and
the anesthesia machine to ensure that
communication connection works
properly. If the communication
connection does not work properly,
replace the communication cable.
2. Check the configuration of the
calibration device. Re-configure the
device if necessary.
[00080000] is
displayed The system fails to write to the
EEPROM. 1. Perform the calibration again.
2. Replace the VCM.
[00100000] is
displayed The ACGO switch is in ON
position.
1. Check whether the ACGO switch is
in OFF position.
2. Check the monitoring status of the
ACGO switch on the interface of the
anesthesia machine.
