Failure
A device error has occurred. The measured value is no longer valid.
Function check
The device is in service mode (e.g. during a simulation).
Out of specification
The device is operated:
• Outside its technical specification limits (e.g. outside the process temperature range)
• Outside of the configuration carried out by the user (e.g. maximum flow in parameter
20 mA value)
Maintenance required
Maintenance is required. The measured value remains valid.
