Fault
Operation:
No delivered concentration
or delivered concentration
too high/too low
The vaporizer detection
system (if fitted) of
anaesthetic machine
indicates a different
anaesthetic to the
vaporizer.
Gauge indicates different
anaesthetic to one shown
on vaporizer (applicable
only to monitors with
anaesthestic detection
system).
5327.400 Vapor 2000
Cause
Valves in plug-in connector
damaged
Vaporizer temperature
outside specified operating
range, e.g. because filled
with very cold anaesthetic or
operated over a lengthy
period at high flow rate in
conjunction with high
concentrations.
Operate vaporizer with
carrier gas other than air.
Gauge indicates percent by
volume, not partial pressure.
Vaporizer or anaesthestic
monitor defective.
Coding of plug-in adapter or
vaporizer damaged, faulty or
incorrectly assembled.
A different anaesthetic was
used previously. There is still
a major concentration of that
anaesthetic in the breathing
system.
Gauge not yet switched after
anaesthestic change.
Wrong anaesthetic or
anaesthetic mixture in
vaporizer.

Remedy
Repair (only by trained
specialists).
Temperature-stabilize
vaporizer, at least 15
minutes per °C deviation
from specified range.
Concentration changes due
to carrier gas.
Convert measured value to
partial pressure.
Use another vaporizer to
check whether the vaporizer
or the anaesthestic monitor
is defective. Repair (only by
trained specialists).
Check coding, re-assemble
as necessary. Repair (only
by trained specialists).
Flush out breathing system
or wait for gas change.
Switch gauge.
Check, drain and blow out
vaporizer. Repair (only by
trained specialists).
