2.2. Electrical system
Aeon8700 machine is divided into two parts, the upper part and down part. The upper parts of
machine provide the operation, alarm and system management functions. The down parts of
machine realize the functions of signal collection, signal process and critical controlling(mode
algorithm) to improve the system integration and stabilization grade, and realize the function of
power management and flowmeter electrical displayed through using MCU.
First, the gas flow and pressure signal convert to electric signal via the flow and pressure sensor.
After the magnification and regulation circuit, the electronic signal converts to digital signal
through the AD conversion circuit. The controller manages the electrical element to realize the
ventilation function. Aeon8600A anesthesia machine is a multi-processor system, the down part
of machine can complete the controlling function while the upper part of machine can realize the
operator-machine intercommunication function; the controller on the communication board can
deal with the keyboard input data and manage the power supply, also can monitor the working
state of host through the communicating data.

Aeon8300A Service Manual
If both the two voltage are over 24V, that’s to say PSB is with a malfunction.
If one or two voltage is less than 24V, that’s to say cable connected to the battery is with a
malfunction.
Problem 3 Automatic Leak Test failure--- Startup Self-test
Phenomenon:
The automatic leak test fails during the startup self-test.
Action:
1.
Observe the airway pressure gauge value during Automatic Leak Test.
The normal airway pressure values changing during Automatic Leak Test:
First, the airway pressure ascends to 80cmH2O, and then quickly descends to 50 cmH2O, and
then descends to 30 cmH2O slowly and stays at 30 cmH2O for a while.
2.
If the airway pressure ascends slowly or even doesn’t ascend, the flow valve needs
calibration.
3.
If the airway pressure descends from 30 cmH2O without staying, that to say the machine has
a leakage.
Problem 4
Flow valve calibration failure
Phenomenon:
The flow valve calibration in the Service Mode fails.

Problem 8
Bellows move downwards abnormally
Phenomenon:
In the progress of automatic leak test during startup, the bellows falls rather than stays at the top
of bellows cover after the bellows is full filled with gas when pressing “O2+”.
The bellows falls abnormally by accident during normal ventilation, at the same time the leak test
result is normal.
Action:
The phenomenon above indicates that there is something wrong with the bellows check valve.
Replace the bellows check valve:
1.
Remove the bellows cover, bellows and disconnect breathing system heating line, drive gas
tube and corrugated hose.
2.
Remove four M4 screws of breathing system shown as the follow picture.

6. Maintenance Information
6.1. Maintenance introduction
This chapter of the Service Manual provides the necessary technical information to perform
repairs to the system. The most important prerequisites for effective troubleshooting are a
thorough understanding of the system's functions, as well as understanding its principles of
operation.
Warning :
Whenever using anesthetic gases, nitrous oxide, oxygen, or any hospital gas
always follow the appropriate agent evacuation/collection procedures. Use the hospital gas
evacuation system.
Caution
This device uses high pressure compressed gas. When attaching or
disconnecting backup gas cylinders, the user should always turn the cylinder valves slowly. Use
Aeon8600A flow meters to bleed down the pressure, watching the cylinder gauge indicate the
depleting cylinder pressure, before disconnecting the cylinder from the yoke. Always open and
close cylinder valves fully.
Caution
This device operates using compressed gas at high pressures from the hospital
central supply. When connecting gas supply lines attach the hose connection to the machine
before connecting the quick disconnect fitting to the hospital source. Disconnect the supply hose
from the hospital source connection prior to disconnecting it from gas connection fittings.
6.2. Maintenance Guidelines
Identify the problem—Due to the wide variety of potential symptoms, certain problems may be
more subtle than others. Following the guidelines of the tests will help determine the problem, if
one exists.
Avoid shorting component leads together—during repair procedures, it can be tempting to make a
quick series of measurements. Always turn the power off before connecting and disconnecting the
test leads and probes. The accidental shorting of leads can easily stress the components and
cause a second failure (aside from the safety risk).
Use the proper equipment—the equipment listed in "Special Tools Required" is suggested to fulfill
a wide range of troubleshooting requirements. It is imperative to use the designated equipment in
order to ensure proper results of any and all test procedures.
Clean up the repair area—after any repair, clean off the repair area.
