11.2 Fault handling
If a trend signal at the local inputs is no longer available (e.g. due to a faulty sensor),
trends are no longer recorded.
In this case, observe the fault status messages under:
Main menu > Faults > Faults current
If the values are not available via bus, trends are no longer recorded.
After a power failure or when quitting the
Extra configuration menu (restart controller), the
values of the 8-hour and 8-minute views are deleted.
