Fault status messages bus
The fault that occurred last on the wire-bound bus is saved with the fault num-
ber, fault text and the associated device address.
These fault status messages are only visible if they were enabled at the time
of configuration:
Main menu > Faults > Fault status message bus
Acknowledge faults
The current fault status messages can be jointly acknowledged.
Main menu > Faults > Acknowledge faults:
A fault that has not yet been acknowledged is displayed with a flashing
fault symbol. As soon as the fault is acknowledged, the fault symbol
stops flashing.
All pending faults are acknowledged simultaneously and any activated
status outputs deactivated.
If no more water or gas leaks are detected, fault acknowledgement
reopens the water or gas safety shutoff valve.
