Code table Fault group/device code (no. 19)
Using the communication object Fault group/device code, there is the option of representing coded
information concerning the malfunction state of the lighting group or the individual device on the KNX.
For further information, see:
Communication object no. 19
Lamp and ballast faults are sent in a 1 byte communication object together with the number of the DALI
device or the lighting group.
Whether the communication object contains the fault status of the lighting group or of an individual DALI
device is set in the
Parameter window Status - Central
, page 61, using the parameter Send number of the
failed group or failed device. This parameter is visible if the parameter "Fault Group/Device Code" enable
encoded fault message has been parameterized with Yes and the communication object has been
enabled.
The values read via the communication object can be interpreted as follows:
Group-orientated setting:
No fault
Value
0…15
+1 = Number of the lighting group
Lamp fault
Value
64…79
-63 = Number of the lighting group
Ballast fault
Value
128…143
-127 = Number of the lighting group
Device-based setting:
No fault
Value
0…63
+1 = Number of DALI device (ballast no.)
Lamp fault
Value
64…127
-63 = Number of DALI device (ballast no.)
Ballast fault
Value
128…191
-127 = Number of DALI device (ballast no.)
The following code table shows the relationship between the DALI device and/or the lighting group and its
fault status (lamp or ballast fault).
