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.

1.2 Diagnostic information on local display
Up-to-date diagnostic events are displayed along with their status category, diagnostic code and
short text. By clicking the navigator, you can call up additional information and tips on remedial
measures.
1.3 Adjusting diagnostic information
1.3.1 Classification of diagnostics messages
More detailed information on the current diagnostics messages displayed is provided in the
DIAG/Diagnostics list menu.
In accordance with Namur specification NE 107, the diagnostics messages are characterized by:
• Message number
• Error category (letter in front of the message number)
–F= Failure. A malfunction has been detected.
The cause of the malfunction is to be found in the sampling point/measuring point. Any
controller connected should be set to manual mode.
–M= Maintenance required. Action should be taken as soon as possible.
The device still measures/takes a sample correctly. Immediate measures must not be taken.
However, proper maintenance efforts would prevent a possible malfunction in the future.
–C= Function check, (no error)
Maintenance work is being performed on the device. Wait until the work has been
completed.
–S= Out of specification. The measuring point is being operated outside specifications.
Operation is still possible. However, you run the risk of increased wear, shorter operating
life or lower accuracy levels. The cause of the problem is to be found outside the measuring
point.
• Message text
If you contact the Service Department, please cite the message number only. Since you can
individually change the assignment of an error to an error category, the Service Department
cannot use this information.
No current output signal Basic module defective Check with integrated current simulation,
connect mA meter directly to current output.

1.3.2 Adjusting the device behavior
All the diagnostics messages are assigned to specific error categories at the factory. Since other
settings might be preferred depending on the application, error categories and the effect errors
have on the measuring point can be configured individually. Furthermore, every diagnostics
message can be disabled.
Example
The controller returns diagnostics message 531 "Logbook full". You want to change this message
so that an error is not indicated on the display for example.
1. Go to:
– Menu/Setup/General settings/Extended setup/Diagnostics/Device behavior
for device-specific diagnostics messages (as in this example)
– Menu/Setup/Inputs/<Sensor type>/Extended setup/Diagnostics settings/Diag.
behavior
for sensor-specific diagnostics messages.
2. Select the diagnostics message and press the navigator button.
3. Decide:
a. Should the message be deactivated?
b. Do you want to change the error category?
c. Should an error current be output?
d. Do you want to trigger a cleaning program?
4. Deactivate the message, for example (Diagnostics message to "Off").
Configuration options
The list of diagnostic messages displayed depends on the path selected. There are
device-specific messages, and messages that depend on what sensor is connected.

Error current Options
•On
•Off
Factory setting
Depends on the message
Decide whether an error current should be output at the
current output if the diagnostic message display is
activated.
If general device errors occur, the error current is
output at all the current outputs.
In the case of channel-specific errors, the error
current is only output at the particular current
output.
Status signal Options
• Maintenance (M)
• Out of specification (S)

None
You can use this function to select an output to which
the diagnostic message should be assigned.
For sensors with the Memosens protocol:
You first have to configure a relay output for
"Diagnostics" (Menu/Setup/Outputs, assign "Diagnostics"
function and set Operating mode to "as assigned") before
being able to assign the message to an output.
