11.5 Adapting the diagnostic information
11.5.1 Classification of diagnostic messages
In the
DIAG
/
Diagnostics list
menu you can find more detailed information on the current
diagnostic messages displayed.
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 measured value of the affected channel is no longer reliable. The cause of the
malfunction is to be found in the 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 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.
11.5.2 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.
