Failure
Description
Possible Cause Recommended Action
[00000200] is
displayed.
The flow pressure sensor
resolution is incorrect. (The
difference between the maximum
AD value and the minimum AD
value is smaller than or equals to
500 AD. When the step of the
pressure value is greater than or
equals to 1 cm H2O, the
resolution is smaller than 1 cm
H2O to 2 AD.)
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 VCM.
[00000400] is
displayed.
The PEEP pressure sensor
resolution is incorrect. (The
difference between the maximum
AD value and the minimum AD
value is smaller than or equals to
500 AD. When the step of the
pressure value is greater than or
equals to 1 cm H2O, the
resolution is smaller than 1 cm
H2O to 2 AD.)
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 VCM.
[00000800] is
displayed.
The valve output pressure is
insufficient.
1. Check whether the gas supply
volume is sufficient for the whole
calibration process.
2. Use the valve diagnosis tool to
check that the maximum output
pressure of the PEEP valve is greater
than 90 cm H2O. If not, replace the
flow module.
[00001000] is
displayed.
The pressure change is not
unidirectional.
1. Check whether the sampling line is
connected correctly.
2. Replace the VCM.
[00002000] is
displayed.
The communication between the
calibration device and the
anesthesia machine is interrupted.
1. Check the communication cable
connection between the calibration
device and the anesthesia machine.
2. Replace the calibration device and
perform the calibration again.
[00004000] is
displayed.
The system fails to write to the
EEPROM.
1. Perform the calibration again.
2. Replace the VCM.
