The CPU board fails to
communicate with the
auxiliary VCM for 10s.
1. Restart the anesthesia machine.
2. If the status screen has a
communication stop alarm, or encounters
the black or blank screen error, rectify
the fault of the status screen first (refer to
7.2.1).
3. If the problem persists, re-plug the

Error
High
The VCM voltage is
beyond the normal
range.
1. Restart the anesthesia machine.
2. If the power board has a voltage error
alarm, clear this alarm (refer to 7.3.3).
3. Select Setup > Service > Data
Monitors > VCM and check whether the
voltages in the A/D channel fall within
the range specified in the A/D channel
table. If yes, the alarm will disappear in
3-5s.
4. If the power supply voltage is out of
the normal range, replace the monitoring
and controlling assembly (refer to
11.1.11).
PEEP Valve
Failure
Med
1. A PEEP valve voltage
error occurs.
2. A PEEP valve
pressure error occurs.
1. Restart the anesthesia machine.
2. If the power board has a voltage error
alarm, clear this alarm (refer to 7.3.3).
3. Select Setup > Service > Data
Monitors > PEEP Valve to run a PEEP
valve test. If the test fails, replace the
drive gas assembly (refer to 11.1.17).
4. If the PEEP valve test is passed, check
whether the PEEP valve or PEEP
pressure sensor is faulty by referring to
7.6.2.
5. If the pressure sensor is faulty,
perform the pressure sensor calibration
