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 (example):
– Error type: S = system error, P = process error
$
– Error message type: = fault message, ! = notice message
– EMPTY PIPE = Type of error, e.g. measuring tube is only partly filled or completely empty
– 03:00:05 = duration of error occurrence (in hours, minutes and seconds)
– # 401 = error number

message only.
