DIAGNOSTICS AND TROUBLESHOOTING
The MODEL 54 Conductivity Analyzer automatically
searches for fault conditions that would cause an error
in the measured reading. If such a condition occurs,
the current outputs and relays will act as configured in
Section 3.4 and Section 3.5 , the red “FAIL” LED on the
front will illuminate and the display will flash a diag-
nostic message.If more than one fault exists, the dis-
play will sequence through the diagnostic messages.
This will continue until the cause of the fault has been
corrected.
Troubleshooting is easy as 1, 2, 3 . . .
Step 1 Look for a diagnostic fault message, on the
display, to help pinpoint the problem. Refer
to
Table 5-1 for an explanation of the mes-
sage and a list of the possible problems that
triggered it.
Step 2 Refer to the Quick Troubleshooting Guide,
Table 5-2 , for common conductivity loop
problems and the recommended actions to
resolve them.
Step 3 Follow the step by step troubleshooting
approach, offered in
Section 5.3 and
Section 5.4 , to diagnose less common or
more complex problems.
