Project design and programming
The following communication objects are only activated and visible if the
corresponding parameter setting has been carried out. The KNX can be
monitored with these communication objects. The number of DALI
devices can be fixed for continious monitoring.

C, R, T
General Fault 230 VAC [EIS 1; 1-bit switching]:
If the 230 VAC supply voltage of the DALI
Gateway should fail for more than 5 seconds, a fault telegram is sent immediately.
The communication object is only visible if the parameter “Send telegram ‘Fault 230 VAC’”
is set to “yes” in the
Status
parameter window.
Telegram value
“1”: Fault
“0”: No fault

General Fault Acknowledgement [EIS 1; 1-bit switching]:
The 1-bit input communication
object enables both the reset of the 230 V AC fault signal and the ballast, lamp and DALI fault
signals of the individual channels. The communication object is only visible if the parameter
“Acknowledge faults” is activated in the
Status
parameter window. The fault(s) is (are) only
reset after an acknowledgement if the corresponding fault(s) has (have) been rectified.
Telegram value
“1”: Reset fault(s)
“0”: No function

General Telegr. Communication send [EIS 1; 1-bit switching]:
To regularly check
the presence of the DALI Gateway on the KNX, a monitoring telegram can be sent
cyclically on the bus. The communication object is only visible if the parameter “Send/receive
communication telegram cyclically” has been set to “send telegram” or “send/receive
telegram” in the
Status
parameter window.
