Error / fault status messages
The central apartment unit stores up to 10 current fault status messages
according to priority. They can be retrieved at any time. The lowest fault status
message number represents the fault with the highest priority. If priorities are
equal, the faults are listed in chronological order.
Both the central apartment unit’s internal faults and the faults of the other
devices contained in the system are taken into consideration.
Each device
only transmits its most severe fault to the central apart-
ment unit. As soon as that fault has been rectified, the next fault is
transmitted.
The faults acquired are written to the “Current list of faults“.
Main menu > Faults > Faults current > Fault X:
With each fault status message, a fault number and fault text are displayed.
The faults can be linked to internal or external fault relays. The rele-
vant relay is energized when the fault occurs (refer to page 77).
Fault status messages bus
The fault that occurred last on the wire-bound bus is saved with the fault
number, 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:
Acknowledging faults
The current fault status messages can be jointly acknowledged.
Main menu > Faults > Acknowledge faults:
A fault that has not yet been acknowledged appears on the display
with a flashing fault symbol. As soon as the fault is acknowledged, the
fault symbol will stop flashing.
