Analyzer with NumaView™ Software
083730510A DCN8172
The analyzer has been designed so that problems can be rapidly detected, evaluated and
repaired. During operation, it continuously performs diagnostic tests and provides the
ability to evaluate its key operating parameters without disturbing monitoring operations.
A systematic approach to troubleshooting will generally consist of the following five steps:
1. Note any Alerts and take corrective action as necessary (see Table 5-3).
2. Examine the values of all basic functions in the Dashboard and compare them
to factory values. Note any major deviations from the factory values and take
corrective action.
3. Use the internal electronic status LEDs to determine whether the electronic
communication channels are operating properly.
•
Verify that the DC power supplies are operating properly by checking the
voltage test points on the relay PCA.
•
Note that the analyzer’s DC power wiring is color-coded and these colors
match the color of the corresponding test points on the relay PCA.
4. Suspect a leak first!
•
Customer service data indicate that the majority of all problems are
eventually traced to leaks in the internal pneumatics of the analyzer or the
diluent gas and source gases delivery systems.
•
Check for gas flow problems such as clogged or blocked internal/external
gas lines, damaged seals, punctured gas lines, damaged / malfunctioning
pumps, etc.
5. Follow the procedures defined in Section 2.3.4.3 to confirm that the analyzer’s
vital functions are working (power supplies, CPU, relay PCA, touchscreen, PMT
cooler, etc.).

LERTS
Table 5-3 lists brief descriptions of warning Alerts that may occur during start up and
describes their possible causes for diagnosis and troubleshooting..
It should be noted that if more than two or three warning Alerts occur at the same time, it
is often an indication that some fundamental sub-system (power supply, relay PCA,
motherboard) has failed rather than an indication of the specific failures referenced by the
warnings.
