is out of range, replace the ventilation control
board or VCM board assembly.
2. If the AD of the zero point of each sensor is
within the valid range, check whether the
software of the VCM board is compatible with
the system software version. If incompatible,
upgrade the software of the VCM board to the
compatible version. If compatible, perform the
factory pressure calibration. If the problem
persists after the calibration, replace the
ventilator control board or VCM board
assembly.

For VCM:
1. The monitored
value of PEEP sensor
or Paw sensor is out of
range.
2. The zero point of
the PEEP sensor or
Paw sensor is
abnormal.
3. The PEEP sensor is
reversely connected.
1. Check whether the pressure sampling line is
connected correctly.
2. Zero the pressure and flow of each sensor.
3. Check whether the AD of the zero point of
each sensor is within the valid range. If the AS
is out of range, replace the ventilator control
board or VCM board assembly.
4. If the AD of the zero point of each sensor is
within the valid range, check whether the
software of the VCM board is compatible with
the system software version. If incompatible,
upgrade the software of the VCM board to the
compatible version. If compatible, perform the
factory pressure calibration. If the problem
persists after the calibration, replace the
