3.3.6 Diagnosis levels
The devices largely monitor their function autonomously. The following diagnosis
levels are derived from the different control measurements:
Normal
Fault
For details, see table below.
When an error occurs which impairs the correct functionality of the module, a
module fault message is reported. The module contains additional information for
addressing the cause. This can be displayed by the FDUD292 detector exchanger
and tester or FDUD293 intelligent detector tester for example.
You will find additional information in documents 007227 and 009718.
