AA Vaporizer
Selftest Error
High
An AA vaporizer
self-test error occurs.
Rectify the fault based on the alarm
error code by referring to 7.3.6.1.
AA Vaporizer
Comm Stop
High
Communication with
the CPU board stops.
1. 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).
2. Reinstall the electronic vaporizer.
3. Replace the electronic vaporizer
slot. If the problem is solved,
restart the machine.
If the problem persists, replace the
electronic dock adapter board (refer
to 11.4.1).
If the problem persists, replace the
monitoring and controlling assembly
(refer to 11.1.11).
4. If the problem persists, replace
the electronic vaporizer.
5. After the electronic vaporizer is
replaced and inserted, conduct the
power-on selftest, leak test, and
electronic vaporizer test (refer to
5.7).
AA Vaporizer

Abnormal
High
The measured output
anesthetic agent
concentration of the
vaporizer greatly
deviates from the
setting.
1. Reinstall the electronic vaporizer.
2. Select Setup > Service > Data
Monitors > Vaporizer . On the
vaporizer diagnostics screen, check
the pressure of the vaporizer drive
gas. If the drive gas pressure is
beyond the range of 140-160kPa (20
psi–23 psi), replace the electronic
vaporizer pressure regulator (refer to
11.1.4).
3. If the drive gas pressure is
normal, or the problem persists after
the adjustment, connect the external
AG module, and test the electronic
vaporizer concentration according to
section 7.8.3. Select Setup >
Service > Data Monitors > AG,
and check the measured values of
