3.2.1
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 may have to be taken soon.
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.
