1 Diagnostics and troubleshooting

The sampler continuously monitors its own functions.

The color of the display background changes to red if a diagnostics message for error category

"F" occurs.

The LED beside the display flashes red if a diagnostics message for error category "M" occurs.

1.1 General troubleshooting

1.1.1 Troubleshooting

A diagnostic message appears on the display, measured values are not plausible or you

encounter a problem.

1. See the Diagnostics menu for details on the diagnostic message.

Follow the instructions to rectify the problem.

2. If this does not help: Search for the diagnostic message under "Overview of diagnostic

information" () in this manual. Use the message number as a search criterion. Ignore the

letters indicating the Namur error category.

Follow the troubleshooting instructions provided in the last column of the error tables.

3. If the measured values are implausible, the onsite display is faulty or you encounter other

problems, search under "Process errors without messages" (ä4) or "Device-specific errors"

(ä10).

Follow the recommended measures.

4. Contact the Service Department if you cannot rectify the error yourself. Only cite the error

number.
