Faults

As a matter of principle, the bus operator unit only handles faults of devices
contained on the device list.
When starting up, it can take up to 3 minutes for the device fault information to be
updated, depending on the size of the device list.
When using network topologies with line couplers, it must be made certain that the line
couplers forward correctly the devices' fault information (LTE broadcast) to the bus
operator unit (filter tables must be appropriately configured).
10.1

Display of faults

Fault status messages delivered by the bus users are displayed by the bus operator
unit on a number of menus. Faults can be acknowledged by the bus operator unit and –
if permitted by the respective device – can also be reset.
The fault LED in the fault button flashes or is lit when faults are pending:
State of LED
LED dark
LED flashes
LED lit
The state of the LED (flashing / steady on) can differ between the bus operator unit and
a bus user if a fault relay has been configured on the operator unit.
Additional information about faults is given at different locations:
Location
Info page Fault status message bus
Device list on the Main menu
Menu Faults current
Menu Fault status message bus
Fault menus of the respective de-
vices
The type of acknowledgement of a fault status message is determined by the fault
source (e.g. Synco™ 700 controller). Depending on the type of acknowledgement
demanded, a fault status message is acknowledged in one of the 3 following ways:
Type of acknowledgement
None
