VA3000 DIAGNOSTICS
2.0 DIAGNOSTICS
The VITALERT 3000 Series contains a diagnostic system that monitors certain system
functions and records their operational status. A series of tests is performed when the
instrument is powered up and the results are displayed on the diagnostics screen shown in
Figure 2-1. If any of these tests fail, consult Section 3 for proper corrective action.
The operational status of the VITALERT 3000 Series is shown at the end of the power-up
self-diagnostics and will be one of the following:
FUNCTIONAL: All self-diagnostic tests pass, and the instrument begins normal
monitoring operation.
CONDITIONALLY A non-critical fault has been detected, and the MONITOR key
FUNCTIONAL must be pressed to continue operation. The instrument may
continue to be used in this situation, but steps shall be taken to
eliminate the problem.
NON-FUNCTIONAL: The self-diagnostic tests reveal a problem in the instrument. A
summary of the diagnostic results is posted and normal
operation is inhibited. The instrument cannot be operated until
the problem is corrected.
Further diagnostic functions are available through service screens that can be accessed as
described on the following pages. If no display is present upon system power-up, refer to
Section 3 of this manual for troubleshooting assistance.

VA3000 TROUBLESHOOTING GUIDE
3.0 TROUBLESHOOTING
This section contains information to assist the Technical Service Representative (TSR)
in locating electrical faults affecting the VITALERT 3000 Series monitors. Since most
troubleshooting efforts begin with verifying power supply voltages, the following
paragraph outlines the voltage distribution scheme within the instrument along with
cable connector identification.
3.1 Power Supply and Voltage Distribution
Figure 3-1 shows a block diagram of the voltage distribution within the
VITALERT 3000 from the power supply. J7 on the Gas Analyzer Interface PCB
(see Figure 3-2) provides the safest, most convenient point to measure power
supply voltages. The voltages are given in Table 3-1 along with their allowable
tolerances. Refer to Section 4 of this manual for appropriate removal and
replacement procedures.
