Symbols Meaning
Error message "Failure detected"
An operating error has occurred. The measured value is no longer valid.
The display alternates between the error message and "- - - -" (no valid
measured value present), see "Diagnostics events" →  39 section.
"Service mode"
The device is in service mode (e.g. during a simulation).
"Out of specification"
The device is being operated outside its technical specifications (e.g.
during warm-up or cleaning processes).
"Maintenance required"
Maintenance is required. The measured value is still valid.
The display alternates between the measured value and the status
message.
DIN rail transmitter
The DIN rail transmitter version does not have an interface to the LC display and
therefore does not have a local display either.
