Sensor Zero
Failed L The zero point of the
sensor exceeded the range. 1. Disconnect the breathing circuit
from gas supplies. Perform zeroing.
2. Disconnect the sampling line of
the sensor. Observe the range of the
zero point and perform zeroing. If
the zero point still exceeds the
range, replace the monitor board.
Three-way Valve
Failure L Error of three-way valve
electrical signal control
status 1. Check the three-way valve
connection line.
2. Replace the three-way valve
assembly.
3. Replace the monitor board.
The voltage of the heating
module exceeded 16V. 1. Measure to or in the A/D
channels confirm if the heating
voltage of the heating module
exceeds the standard.
2. If the heating voltage of the
heating module exceeds the
standard, replace the power board.
Heating failure (the
temperature of two
thermistors is less than 35
degrees continuously)
Heating Module
Error L
Overtemperature
1. Confirm the measurement
temperature in the A/D display
channels.
2. Check the status of the
thermistor.
3. Check the status of the heater.
4. Replace the power board.
IP Address
Conflict M IP address conflict 1. Set the IP address again.
2. If the problem persists, update
the system software code or replace
the main control board.
TVe>TVi L TVe was greater than TVi
for 6 consecutive breathing
cycles to some extent. 1. Check if pneumatic connection,
leak and fresh gas delivery are
normal.
2. Check the measurement accuracy
of the sensor.
3. Perform calibration in case of
measurement failure.
TV Delivery Too
High L TVi was greater than the
set value for 6 consecutive
breathing cycles to some
extent. 1. Check the measurement accuracy
of the sensor.
2. Perform calibration in case of
measurement failure.
