(Include RMA Number)
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 3 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 3 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.

NM3 DIAGNOSTICS
2.0 DIAGNOSTICS
When the Narkomed 3 is powered up, each of the monitors performs a six-second self-
diagnostic check and lamp test. The display window on each monitor should show a power-up
code number, and all LED indicators and backlit labels should illuminate. The left-hand CRT
will then show the Centralert Alarm display and the right-hand CRT will show the Data
display.
Table 2-1 lists the possible error codes that may appear in monitor display windows at power-
up or during subsequent use. Record any error codes that appear and communicate them to
the NAD Service Department, or AuthorizedService center during any troubleshooting effort.
Followingthecompletionofthemonitorself-tests,theTechnicalServiceRepresentative(TSR)
can call up service screens at the display panel. The following paragraphs describe each
service screen. If no display is present on the Centralert Alarm CRT or the Data CRT, refer
to Section 3 of this manual for troubleshooting assistance.

2.1 Service Selection Screen
To access the Service Selection Screen, press and hold the LOG DATA key and
the hidden key directly to the right of the LOG DATA key, then press the
CHECKOUT key. The Service Selection screen appears as shown in Figure 2-1.
The Service Selection Screen displays the available service functions. Access
to these service functions is gained through the Centralert CRT control keys
below the service screen which temporarily function according to their
corresponding on-screen labels. The SELECT key advances the cursor to the
desired menu option, and the ENTER key opens the selected service screen.
Pressing the END CONFIGURE key exits the Service Selection Screen. This
screen also exits automatically after two minutes have elapsed.

To access the Configuration Screen, press the SELECT key (see Figure 2-1) to
advance the cursor to the CONFIGURE DEFAULTS option, and then press the
ENTER key. Figure 2-2 shows the Configuration Screen.
This screen allows the TSR to set power-up default alarm limits and display
selections for each monitor in the machine. The default values are stored with
the SAVE key. Press the END CONFIGURE key to return to the Service
Selection Screen. The Configuration Screen also exits automatically after two
minutes have elapsed.

NM3 TROUBLESHOOTING GUIDE
3.0 TROUBLESHOOTING
This section contains information to assist the Draeger Medical, Inc. qualified
Technical Service Representative (TSR) in locating electrical faults affecting the
NARKOMED 3 monitoring and display devices. Since most troubleshooting efforts
begin with verifying power supply voltages, the following paragraphs outline the
voltagedistributionschemewithinthemachinealongwithconnectorpinidentification
and wire colors.
Also contained in this section are troubleshooting guide flow charts that provide a
method of tracing faults to specific field replaceable assemblies or sub-assemblies in
response to observed failure modes or symptoms.
3.1 Power Supply and Voltage Distribution
In the NARKOMED 3, power for the monitors and CRT displays is distributed
from a terminal block located in the rear of the monitor housing. This terminal
block is accessible by opening the back cover of themonitor housing. Figure 3-1
shows the terminal block inputs and main DC power wiring harness
connections to the power controller PCB assembly.
Table 3-1 shows the nominal DC voltages at the power distribution block and
their acceptable tolerances , under normal load with rated AC voltage applied
to the machine and the System Power switch set to ON.

Figure 3-2 shows the power distribution from the terminal block to the field
replaceable assemblies and CRTs, and also to the backplanes which provide
power distribution to the monitors.

3.3 Troubleshooting Guide Flow Charts
Table3-3lists severalcommonpossible failuremodesandsymptoms(excluding
simultaneous multiple faults) for the monitoring devices in the NARKOMED
3. Each failure mode or symptom is keyed to a troubleshooting guide flow chart
to assist the Technical Service Representative 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.
