1. Important
Hazard notices
• Before disassembling or assembling the KION
and/or the KMG 2000, make sure that the:
– Gas supply is disconnected.
– Mains power cable is disconnected.
– KION power switch is set to Off. If the power
switch is set to Standby or On, the internal
battery will supply power to the PC boards.
– Internal battery is disconnected when working
inside the Power & Communication interface.
– The system is cleaned according to instructions
in the KION – Operating Manual, chapter
Routine cleaning.
• With power supply connected to the KION
System, there are energized electrical components
inside the unit. All personnel must exercise
extreme caution if fault tracing or adjustments are
performed with power supply connected.
Warnings
• The KMG 2000 must not be used with flammable
anesthetic agents.
• Water emptied from the water trap
should be disposed of in accordance
with local regulations for contaminated
and biologically hazardous fluids.
• The water trap should be disposed of in
accordance with local regulations for
contaminated and biologically hazardous
items.
• The evacuated gas must be handled in a suitable
manner to prevent hazardous levels of anesthetic
gases to be built-up in the ambient air.
• Analyzer performance is likely to be degraded in
the presence of operating electrosurgical or
diathermy equipment.
Service
• The KMG 2000 must be serviced at
regular intervals by personnel trained
and authorized by Siemens.
Any maintenance or service must be
noted in a log book.
• Preventive maintenance must be performed at
least once every year as long as the unit is not
used more than normal. Normal operation is
estimated to correspond to approx. 5.000 hours
of operation. Details are found in this Service
Manual, chapter ”Preventive maintenance”.
• It is recommended that maintenance
and service is done as a part of a service
contract with Siemens.
• All disposable parts shall be discarded

2.3 Functional principles
This description refers to the functional block
diagram, see chapter Diagrams.
2.3.1 Gas sampling system
The KMG 2000 samples a continuous gas flow from
the patient breathing circuit to measure concentrations and to identify gases in the breathing gas. A gas
pump creates and controls the gas flow through the
sampling system.
From the gas sampling line, the gas enters the water
trap where water droplets and secretions are
separated from the flow and collected in the water
trap container.
In the water trap, the gas flow is divided in two parts:
• The sampling gas flow, approx. 90% of the total gas
flow.
• The purge gas flow, approx. 10% of the total flow.
Both gas flows passes a filter inside the water trap.
This filter protects the sampling system from
condensed water, secretions, bacteria and other kind
of contamination.
The sampling gas flow passes:
• The Nafion tube where the moisture content and
the temperature in the sampled gas are equalized
to that of the ambient air.
• The Zero Calibration Valve (ZCV). Zero calibrations
are performed automatically at regular intervals.
• The Gas Measurement Bench (GMB). The CO
and anesthetic agents are identified and measured
in the Gas Measurement Bench (GMB).
• The O2 Sensor where the O2 content is identified
and measured.
The purge gas flow passes:
• The Purge Flow Valve (PFV). The PFV automatically
flushes the sampling system if the sampling gas
flow is obstructed.
Both gas flows are now mixed and connected to the
pump. After passing the pump, the gas flow is routed
back to the patient breathing circuit via the evacuation
outlet.

digital information is delivered to the KION Display via
the Protocol Converter (PrC).
2.3.3 Control system
The pump and thus the gas sampling flow rate is
controlled by information from the water trap
receptacle. Switches in the water trap receptacle
identifies if a water trap is connected.
Calibration information is stored separately in
EEPROMs in the GMB, in the pump and in the AION
PC board.
Software upgrades/updates of the AION-SW and the
PrC-SW, can be performed via a PC connected to P1.
The switches SW1 and SW2 selects the flash memory
to be upgraded/updated.
The 24 V DC power is supplied via connector P2 from
the KION power supply. Both the SCM300 PC board
and the AION PC board has separate DC/DC
converters and 5 V stabilizers.

The DRYLINE™ water trap protects the gas analyzer
system from condensed water, secretions, bacterial
contamination and dust. It consists of two parts, a
filter housing with hydrophobic anti-bacterial filter and
a container for separated waste.
The filter housing has one gas sample inlet to be
connected to the sampling tube.
In the water trap, the sampling flow is divided in two
parts:
• Sampling gas flow (approx. 90%).
• Purge gas flow (approx. 10%).
There are two outlets in the filter housing, one for
each gas flow.
The DRYLINE water trap to be used with the
KMG 2000 is designed for a sampling flow of 120–
200 ml/min. For further information, see Water trap
receptacle below.
3.2 Water trap receptacle
The water trap is connected to the water trap
receptacle. There are two gas connections on the
receptacle; one for the sampling gas flow and one for
the purge gas flow.
The two electrical switches on the water trap
receptacle detects if a water trap is present and
identifies the version of the connected water trap.
The water trap receptacle is designed to identify two
different water trap versions:
• The high-flow water trap. This version of the water
trap is to be used with the KMG 2000. The water
trap activates both switches. The sampling flow is
by default set to 200 ml/min, but can be changed to
120 ml/min via the KION Display, refer to the User's
manual.
• The low-flow water trap. This version of the water
trap is not used in this application. It activates only
the lower switch. This low-flow water trap is intended to be used in applications where the sampling
gas is not routed back to the patient circuit.
If no water trap is connected or if a water trap
without container is connected, both switches are
inactive. The pump, and thus the gas flow through
the KMG 2000, is automatically stopped to prevent
contamination.
The control signal cable from the water trap
receptacle PC board is connected to the SCM300 PC
board via connector P4a.

3.3 Nafion tube
The NafionTM tube equalizes the moisture content and
the temperature in the sampled gas to that of the
ambient air. This is to reduce the influence on the
measurements from humidity and to prevent from
water condensation inside the sampling system.

• Update the configuration stored in the AION
EEPROM if the AION unit has been replaced.
This is done to secure traceability and to allow
correct revision number to be shown on the
KION Display.
Zero Calibration Valve (ZCV): To establish a gas
zero concentration reference, ambient air is routed
through the Gas Measurement Bench via the Zero
Calibration Valve.
The automatic zero calibration of the AION will be
performed:
• During warm-up
• At a temperature change >1 °C (in the GMB)
• Every 4 hours
• At gas span calibration.
Purge Flow Valve (PFV): During normal sampling
condition there is always a small purge flow, approx.
10% of the total flow, through the KMG 2000. This
purge flow is created by the purge flow restrictor.
If there is an obstruction in the sampling line, this will
be detected by the flow sensor in the pump as a
decreased flow.
If the total flow from the two water trap outlets drops
below 40 ml/min for more than one second, the
forced purge flow-function is activated during 12
seconds. This forced purge flow is created by the
Purge Flow Valve connected in parallell with the
purge flow restrictor. The forced purge flow forces
water and secretions in the sampling line into the
water trap container. The forced purge flow is routed
from the water trap directly to the pump and out
through the evacuation outlet. It will not pass the Gas
Measurement Bench or the O
Sensor.
2
If the total flow remains below the limit value, the
forced purge flow-function will be repeated up to four
times until further forced purge cycles are inhibited.
The purge function is automatic and is not possible to
start manually.
