Insp Valve
Failure/Insp Valve:
Failed
Med
The Insp valve voltage is in
error.
The Insp valve flow is in
error.
1. Power on the machine again for
a self-test.
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 7.6.3.
5. If the pressure sensor is faulty,
perform the pressure sensor
calibration (refer to 6.3.5).
6. If the calibration fails, replace
the sensor adapter board (refer to
11.1.16).
7. If the problem persists, replace
the monitoring and controlling
assembly (refer to 11.1.11).
Safety Valve
Failure/Safety
Valve: Failed
Med
The voltage of the PEEP
safety valve is in error.
The PEEP safety valve
cannot be properly closed or
opened.
1. Power on the machine again for
a self-test.
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 Safety Valve to
run a PEEP safety valve test. If the
test fails, replace the drive gas
assembly (refer to 11.1.17).
Flow Sensor
Failure/Flow
Sensor: Failed
Low
The flow on the machine
side is out of range.
The zero point of the flow
sensor on the patient side is
abnormal.
1. Zero the flowmeter.
2. Diagnose the flow sensor by
referring to 4.6.1.2.
3. If the measured value of the
flow sensor in step 2 is valid but
the error is large, perform the flow
calibration.
4. If the measured value of the
flow sensor in step 2 is invalid or
calibration fails, replace the sensor
adapter board (refer to 11.1.16).
5. If the problem persists, replace
the monitoring and controlling
assembly (refer to 11.1.11).
Calibrate Flow
Sensor and Insp
Valve
Low
1. The calibration table is
not found on the EEPROM.
2. The checksum of the
calibration table does not
match.
1. Calibrate the flow sensor (refer
to 6.3.1).
2. If the problem persists, replace
the monitoring and controlling
assembly (refer to 11.1.11).
