Explanation, example
"Coming" => a message is triggered when a
fault is received (start of fault).
"Coming and going" => a corresponding
message is triggered at the start and end of a
fault.
LED "Local" indicates a fault at a fault input.
Text input comprising max. 20 alphanumeric
characters. If there is no other entry, message
text "[Fault inp 1...20] n flt" applies.
Text input comprising max. 20 alphanumeric

text "[Fault inp 1...20] fault" applies.
Explanation, example
"Coming" => a message is triggered when a
fault is received (start of fault).
"Coming and going" => a corresponding
message is triggered at the start and end of a
fault.
This "Message triggering" applies to device
faults on the KNX network (system) sent via bus
to the central communication unit. The LED
"System" indicates a fault "System".
Explanation, example
Setting value "All" means that the fault relays
are controlled for all types of faults (Urgent and
Not urgent).
Setting values "Urgent" and "Not urgent" are
used as a filter, i.e. the fault relays are only
controlled if there is a fault with relevant "Fault
priority".
Use setting values "Local" and "System" as
separators to control the fault relays.
Setting value "Local" controls "Fault relay 1" or
"Fault relay 2" only for "Local" faults.
Accordingly, "Fault relay 1" or "Fault relay 2" are
controlled only for "System" faults.
