There is a zero point error for the
flow pressure sensor.
1. Check the zero point.
2. Replace the VCM.
[00000010] is
displayed.
There is a zero point error for the
PEEP pressure sensor.
1. Check the zero point.
2. Replace the VCM.
[00000020] is
displayed.
The measured range of the flow
pressure sensor is abnormal.
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.
[00000040] is
displayed.
The measured range of the PEEP
pressure sensor is abnormal.
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.
[00000080] is
displayed.
The calibration data of the flow
pressure sensor does not satisfy
monotonicity.
1. Check the sampling line connection
and tightness.
2. Check the gas supply pressure.
3. Troubleshoot the sensor and valve
fault using the valve diagnosis tool.
For details, see section 5.4.
4. Replace the VCM.
[00000100] is
displayed.
The calibration data of the PEEP
pressure sensor does not satisfy
