13 Function block faults
13.1 Overview of function block
Function block “Faults“ collects all fault status messages that have occurred, sorts them
according to their importance for display and stores the last 10 messages in the fault
history. The function block signals acknowledgements and resettings made by the user
to the application where the fault occurred. The function block is always active for
delivering internal fault status messages.
For external signal sources, function block “Faults“ provides 4 universal fault inputs, in
addition to the fault inputs of the boiler and the pumps.
It is also possible to monitor inputs, such as flow sensor, room sensor, etc., that have
already been configured.
To signal or forward faults, 2 relays can be configured as fault outputs.
