Liquistation CSF33 Diagnostics and troubleshooting
Endress+Hauser 129
In accordance with Namur specification NE 107, the diagnostic 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 control system connected should be set to manual mode.
• 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 measurement accuracy. The cause of the problem is to be found
outside the measuring point.
• M = (Maintenance required), action should be taken as soon as possible
The device still measures/takes samples correctly. Immediate measures are not
necessary. However, proper maintenance efforts would prevent a possible malfunction
in the future.
• 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.
11.3.2 Adapting the diagnostic behavior
All the diagnostic 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 diagnostic message can be disabled.
Example
Diagnostic message 531 Logbook fullappears on the display. You want to change this
message so that an error is not shown on the display for example.
1. Select the diagnostics message and press the navigator button.
2. Decide: (a) Should the message be deactivated? (Diagnostics message = Off)
(b) Do you want to change the error category?(Status signal)
(c) Should an error current be output? (Error current = On)
(d) Do you want to trigger a cleaning program? (Cleaning program)
3. Example: You deactivate the message.
The message is no longer displayed. In the DIAG menu, the message appears as
Past message.
Possible settings
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.
