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 or via the fieldbus indicating that the measured
values are not plausible, or you identify a fault.
1. See the Diagnostics menu for the 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 for the faults under "Process errors without messages" () or "Device-specific
errors" ().
Follow the recommended measures.
4. Contact the Service Department if you cannot rectify the error yourself. Only cite the error
number.

1.5 Adjusting diagnostic information
1.5.1 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 its specification
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.
1.5.2 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?

Liquistation CSF48 Diagnostics and troubleshooting
Endress+Hauser 15
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.

Depends on the message
You can deactivate or reactivate a diagnostic message
here.
Deactivating means:
• No error message in the measuring mode
• No error current at the current output
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)
•Functioncheck(C)
• Failure (F)
Factory setting
Depends on the message
The messages are divided into different error categories
in accordance with NAMUR NE 107.
Decide whether you want to change a status signal
assignment for your application.
Diag. output Options
•None
• Alarm relay
• Relay 1 to n (depends on
the device version)
Factory setting
None
You can use this function to select a relay output and/or
binary output to which the diagnostic message should be
assigned.
For sensors with the Memosens protocol:
Before you can assign the message to an output, you
must first configure a relay output to "Diagnostics"
(Menu/Setup/Outputs, assign the "Diagnostics" function
and set the Operating mode to "as assigned").
