NM2C DIAGNOSTICS
2.0 DIAGNOSTICS
The Narkomed 2C 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 diagnostics screen shown in Figure 2-1. The display
also includes one of three messages at the completion of the diagnostics:
FUNCTIONAL: This message indicates that the NARKOMED 2C has passed all power-
up tests and is fully functional. The machine will proceed to the
MACHINE MONITOR screen after a short delay.
CONDITIONALLY This message indicates that a minor problem has been
FUNCTIONAL: detected. The NARKOMED 2C will retain this display until the trigger
is pressed, then the MACHINE MONITOR screen will be displayed.
NON-FUNCTIONAL: This message indicates that a serious problem has been
detected. The machine will not proceed into the MACHINE
MONITOR or SYSTEM MONITOR screen.
Further diagnostic functions are available through service screens that can be called up at
the display panel. The following paragraphs provide a description of each service screen that
can be accessed at the display. If no display is present upon system power-up, refer to Section
3 of this manual for troubleshooting assistance.
