HOW TO USE THIS MANUAL
products/material in need of factory repair shall be sent to:
DrägerService
3124 Commerce Drive
Telford, PA 18969 U.S.A.
(Include RMA Number)
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 Technical Service Representative in locating the source of a problem. The
REPLACEMENT PROCEDURES section contains instructions for removal and replacement
of 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 6000 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 any component is 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 is replaced.
The general arrangement of the Narkomed 6000 anesthesia system is shown on the opposite
page.

NM6000 DIAGNOSTICS
2.0 DIAGNOSTICS
The Narkomed 6000 contains a diagnostic system that monitors certain system functions
and records their operational status. A series of tests is performed when the system is
powered up and the results are displayed on the monitor screen. At the completion of the
diagnostics, one of three screens will appear as shown in the following examples:
SYSTEM 1 PASS
VPO Pod PASS
GAP Pod PASS
VENTILATOR PASS
SYSTEM FUNCTIONAL

The screen labeled SYSTEM FUNCTIONAL indicates that all tests have passed. This screen
will be displayed for approximately five seconds, and the system will then proceed to the
monitor screen. (Touching the Continue key will bring up the monitor screen immediately.)
The screen labeled SYSTEM CONDITIONALLY FUNCTIONAL indicates that a problem
has been detected but the system is still usable. This screen will remain displayed until the
Continue key is touched.
The SYSTEM NON-FUNCTIONAL screen indicates that a serious problem has been
detected. The system will not proceed any further.
Further diagnostic functions are available through service screens that can be accessed at
the monitor. The following pages provide a description of the service screens. If no display is
present upon system power-up, refer to Section 3 of this manual for troubleshooting
assistance.

2.8 Divan Ventilator Power-Up Self Test
Upon system power-up from a cold start, the Divan ventilator enters an
automatic self test sequence that takes approximately five minutes to complete.
A flow chart of the self test sequence is shown beginning on the next page. The
test proceeds according to the following schedule:
Electronic tests including all front panel LEDs, solenoids, fan, audible alarms
Prompts to set fresh gas flow to zero, APL valve to 30, close Y-piece
Pressure sensors automatic zero calibration
Power supply voltage tests (four voltages).
Piston position and motor current check
Control pressure test
Pneumatic leakage test on breathing system, and compliance correction
Pneumatic leakage test on fresh gas system
APL valve check
When the self test is completed the Divan display will indicate Standby Mode.
RETURN TO THIS MANUAL'S TABLE OF CONTENTS
RETURN TO CD-ROM TABLE OF CONTENTS
NM6000
If the machine is shut down and then powered up within four minutes (warm
start), the ventilator will skip some of the self tests and proceed to the Standby
Mode.
On a cold start, the power-up self test routine can be bypassed if it is desired to
proceed with operation immediately. In this case, depending upon where in the
sequence the test is interrupted, previously stored values will be substituted for
those elements of the test that are skipped.
The self test can be bypassed by pressing the Man/Spontaneous or the Volume
Mode key. The self test can be bypassed in this manner up to ten consecutive
times. When the machine is powered up the next time and allowed to complete
its self test, the counter is reset to zero. If a bypass is attempted an 11th time,
the display will indicate that the ventilator is in Safe Mode and only manual
ventilation is then possible.
The Divan ventilator also has a service mode, described on subsequent pages,
that allows you to perform some of these tests manually.

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 6000 anesthesia system. Some pneumatic fault locating information is
also included in this section. Most troubleshooting efforts begin with verifying power
supply voltages. The following paragraph summarizes the voltage distribution
scheme within the machine.
3.1 Power Supply and Voltage Distribution
Test points, voltages and their allowable ranges for the Narkomed 6000 system
and Divan ventilator are given in Table 3-1. System voltage is distributed to the
CRT, flowmeter lights and table lamp. Voltage for the VPO assembly and the
gas analyzer pod is supplied via the communication port assembly. A block
diagram of the voltage distribution arrangement is shown in Figure 3-1.
Connector locations are shown in Figure 3-2.
NOTE: If the Vitalbus Hub door on the back of the machine is opened for test
purposes, be sure to reinstall the power cord as shown in Figure 3-4 when the
machine is placed back in service.

3.2 Battery
The battery bank comprises four 12-volt storage batteries connected in series for
a nominal backup supply of 48 V. The battery voltage is monitored by the
system, and a ‘battery low’ signal is generated if the battery voltage drops below
46.8 V (±0.5V). Battery disconnect occurs when voltage drops below 40.0 V
(±0.5V). Battery voltage can be measured at its power supply connector, J5-6 (+)
to J5-1 (-).
Power Cord Routing:
If the Vitalbus Hub door on the back of the machine is opened for test purposes,
be sure to reinstall the power cord as shown in Figure 3-4 when the machine is
placed back in service.
Route the power cord’s strain relief with a loop in a clockwise direction. The
retaining clip shall be located 16.5 ±0.25 inches (5.25 inch diameter loop
approx.) from the cord end and secured to the Vitalbus HUB door using the
mounting hole dirrectly above the power cord socket as illustrated.

3.3 Troubleshooting Guides
Table 3-2 lists common failure modes and symptoms (excluding simultaneous
multiple faults) for the monitoring and display devices, and several ventilator
functions. 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 guides assume that the machine is plugged into an AC outlet with the
correct voltage, and the machine is not running on its backup battery.
