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 Manufacturers 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
SYSTEM 1 PASS VPO Pod PASS GAP NVRAM failure FAIL VENTILATOR PASS
SYSTEM CONDITIONALLY FUNCTIONAL
press key to continue
SYSTEM 1 PASS VPO Pod Firmware FAIL GAP Pod PASS VENTILATOR FAIL
SYSTEM NON-FUNCTIONAL
Continue
Continue
Continue
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.

2.5 Service Dump Notebook

Touch the Service Dump key at the bottom of the screen to display the Service Dump Notebook shown in Figure 2-13. Tabs are displayed for each pod, and for the Narkomed 6000. Touching each tab of the service dump notebook will display dump data for the corresponding page.
Touch the PRINT DUMP key to print out the data on the strip chart recorder. If there is no strip chart recorder on the machine, then touching the PRINT DUMP key will write the data to a file on the hard drive of the NM6000.
To clear the service dump, enter the advanced service menu, then touch the CLEAR DUMP key to clear the service dump data for that page.
Touching the POD LOG button causes the pod log screen to be displayed in the same area as the service log. See next page.
