9.1 Trouble-shooting instructions
Always start trouble-shooting with the checklist below, if faults occur after start-up or
during operation. The routine takes you directly to the cause of the problem and the
appropriate remedial measures.
Caution:
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer
for repair. The procedures on Page 6 must be carried out before you return a device to
Endress+Hauser. Always enclose a duly completed “Safety regulation” form. You will
find a preprinted form at the back of this manual.

Error messages on display
Errors which occur during commissioning or measuring operation are displayed immediately.
Error messages consist of a variety of icons. The meanings of these icons are as follows:
– Error type: S = system error, P = process error
– Error message type:
= fault message, ! = notice message
– PARTIALLY FILLED PIPE = error designation (e.g. measuring tube is only partly filled)
– 03:00:05 = duration of error occurrence (in hours, minutes and seconds)
– #401 = error number
Caution:
• See the information on Page 69 ff.!
• Simulations and positive zero return are interpreted by the measuring system as being system errors-
but are only displayed as notice messages.
