HOW TO USE THIS MANUAL
The manual is divided into several sections. The DIAGNOSTICS section describes self-test and
service diagnostics for checking the system functions. An understanding of the on-board service
capabilities is necessary before any attempt is made to troubleshoot the unit. The
TROUBLESHOOTING section lists error codes and provides troubleshooting guides to assist the
TSR in locating the source of a problem. The REPLACEMENT PROCEDURES section contains
instructions for removal and replacement of the assemblies that are considered field-replaceable.
The ADJUSTMENT AND CALIBRATION PROCEDURES section contains the field procedures
needed to restore original system specifications. The Periodic Manufacturer’s Service (PMS)
PROCEDURE section outlines the steps required to verify the electrical, mechanical and
pneumatic safety of the unit and also identifies components requiring periodic replacement.
GENERAL TROUBLESHOOTING GUIDELINES
Troubleshooting the Narkomed 2C should always begin by communicating with those who
observed or experienced a problem with the unit. This may eliminate unnecessary troubleshooting
steps. Once a general problem is identified, refer to the troubleshooting flow charts in Section 3
to determine the proper corrective action to be taken.
After a component has been replaced, verify that the unit is operating properly by running the
appropriate diagnostic procedure. The PMS PROCEDURE in Section 6 must also be performed
after any component has been replaced.
The general arrangement of the Narkomed 2C Anesthesia System is shown on the opposite page.
WARNINGS are used in this manual before procedures which if not performed correctly could
result in personal injury.
CAUTIONS are used in this manual to alert service personnel to the possibility of damage to the
equipment if a procedure is not performed correctly.

TROUBLESHOOTING GUIDE
TROUBLESHOOTING
This section contains information to assist the Draeger Medical, Inc. qualified
Technical Service Representative (TSR) in locating electrical faults affecting the
NARKOMED 2C monitoring and display devices. Since most troubleshooting efforts
begin with verifying power supply voltages, the following paragraph outlines the
voltage distribution scheme within the machine along with test points for each of the
voltages.
3.1
Power Supply and Voltage Distribution
In the NARKOMED 2C, +5VDC, +12VDC and -12VDC are supplied to J15 on
the processor board; +8VDC is supplied to J4 on the alarm channel and is also
distributed to the ventilator controller via J3 on the alarm channel. These
voltages can be measured at the connectors shown in Figure 3-1. Table 3-1 lists
the acceptable range for each voltage under normal load conditions. Figure 3-2
shows a block diagram of the NARKOMED 2C, including the primary and
secondary voltage distribution scheme.

While the machine is operating from an AC line, the battery voltage at full
charge should be within the range of 12.83 to 14.18 VDC. Battery voltage can
be measured at TB1, terminals 1 and 2, on the power supply. During battery
operation, the low battery cutoff voltage should be within the range of 10.5 to
10.0 VDC.

Troubleshooting Guides
Table 3-2 lists common failure modes and symptoms (excluding simultaneous
multiple faults) for the monitoring and display devices in the NARKOMED 2C.
Each failure mode or symptom is keyed to a troubleshooting guide flow chart
at the back of this section to assist the TSR in locating a problem. These flow
charts assume that the machine is plugged into an AC outlet with the correct
voltage, and the machine is not running on its backup battery.

ADJUSTMENT AND CALIBRATION PROCEDURES (continued)
CAUTION: Based on information supplied by the cylinder regulator manufacturer,
when the regulator is used for gases other than N2O or CO2, its output pressure will
decrease 0.5 psi for every 100 psi increase in cylinder pressure above 1000 psi.
Currently, these regulators are calibrated at 47 psi with a cylinder supply of 1000 psi.
If a 2000 psi cylinder is then installed, the regulator output will be 42 psi. This
change in output must be compensated for to provide accurate performance
throughout the cylinder’s working range.
NOTE: Cylinder pressure compensation for the N2O regulator is not required.

Periodic Manufacturer’s Certification General Instructions
The purpose of these procedures is to provide detailed instructions for performing a Periodic
Manufacturer’s Certification (PMC) inspection on the Narkomed 2C anesthesia machine.
A PMC consists of a complete Periodic Manufacturer’s Service procedure and a certification level
inspection based on Draeger Medical, Inc. Recommendations and equipment performance. Additional
inspections are also performed to insure proper product labeling.
Several additional documents have been created to ensure the success of this new program. Following
is a brief description of the purpose of each document.
Field Service Procedure:
Periodic Manufacturer’s Certification Forms - Part Number SP00175.
This procedure illustrates sample checklists with typical periodic maintenance items filled in,
including vapor concentrations verification tests, parts replaced, general comments and certification
levels. Also included are sample PMC labels marked to show several levels of certifications. An excerpt
from Draeger Medical, Inc.’s Anesthesia System Risk Analysis and Risk Reduction is included, and also
a sample of an Executive Summary to be furnished to the hospital’s Risk Manager or Chief of
Anesthesia.
Field Service Procedure:
DMI Recommendations Guidelines Index Anesthesia Systems - Part Number S010250.
This Guideline was created to provide an assessment of each machine’s certification. It contains
various comprehensive overviews of possible equipment conditions and their associated certification
levels.
The first list in the Recommendation Guidelines is a reference chart for machine certification based
on equipment status. The second is an abbreviated summary of all DMI Recommendations and Failure
Codes including the Condition Number, Equipment Condition, Recommended Corrections, Certification
Code, and Tests Affected when applicable.
There is also a matrix classified as "Failure Codes" which identifies the correct manner in which to
document equipment tests that fail, or were unable to be performed due to circumstances beyond the
control of the service technician performing the inspection. (Ex: Air cylinder supply is unavailable to
perform Air High Pressure Leak test.) The Failure Codes section also indicates suggested resolution
of the situation. Failure Code numbers begin at 34 and use the same certification levels strategy, and
carry the same weight as DMI Recommendation equipment condition codes.
The final matrix is the most comprehensive index sorted by machine model and includes Equipment
Condition, Certification Code, and DMI Recommendations. It also specifies any suggested upgrade
path including ordering information that should be taken such as installing a Bellows with Pressure
Limit Control 4109664-S01 Kit, after market modification kit to a machine not equipped with pressure
limit control.

PMC PROCEDURE (continued)
NM2C
The letters A, B, C, D and the Roman Numerals I, II are used as codes in the individual matrix for
each model of anesthesia machine. The letters A, B, C, and D are used in descending order to indicate
the certification level of the equipment. They are as follows:
A = Certified
B = Certified with Recommendations
C = Conditionally Certified
D = No Certification
Roman Numerals I and II do not affect the certification level but rather are provided to give further
instructions to the end user as follows:
I = The system in its present configuration shall only be used with a CO2 monitor
incorporating an apnea warning. The operator of the system is advised to frequently scan
the CO2 readings and alarm thresholds.
II = The present configuration of equipment requires that the unit operate at all times with an
oxygen analyzer that includes a low oxygen warning. The operator of the system is advised
to frequently scan the oxygen readings and alarm limits.
Following is an explanation of machine certification levels:
Certified- No recommendations apply to machine being inspected. (Only item number 33 - "No
Recommendations" shall apply for this certification level.)
Certified with Recommendations- A numbered recommendation with a code of B applies to the
machine being examined.
Conditionally Certified- A numbered recommendation with a code of BCI or BCII applies to the
machine being examined.
No Certification- A numbered recommendation with a code of D applies to the machine being
examined.
When multiple recommendations apply, "No Certification" would take precedence over "Conditionally
Certified" and "Certified with Recommendations". "Conditionally Certified" would take precedence over
"Certified with Recommendations".

SOFTWARE UPDATE PROCEDURE
SOFTWARE UPDATE PROCEDURE
This section outlines several software installation methods, and also describes the
operation of the Service Software Toolkit (SST).
The Service Software Toolkit (SST) allows all service constants, configurations, logs and
templates to be saved to a disk for later viewing or adding to a service report. These
same constants can be reloaded after a processor has been replaced. The SST can also
be used to install Narkomed 2C software. Actual servicing of the machine is performed
manually without the use of SST.
Software updates to the Narkomed 2C anesthesia system, including communication
protocols for external monitors are done through a serial port connection to an external
PC or through the O.R. Data Manager (ORDM). The software can be downloaded to the
PC via modem, or furnished on a floppy disk.
Following is a summary of the software installation methods described in this section:
--
From an external PC using the batch file LOADNM2C.BAT. Initial installation
will install the SpaceLabs Datalogger, Marquette Tram Net, Datex AS3, and
Criticare POET IQ protocols.
--
From the ORDM. Initial installation will install the SpaceLabs Datalogger,
Marquette Tram Net, Datex AS3, and Criticare POET IQ protocols.
--
From an external PC using the SST. Any desired protocols may be selected.
--
From the ORDM using the SST. Any desired protocols may be selected.
