This group object is enabled if the Enable Group object for additional fault messages "Group number fault" "Switch up next
group fault" parameter is set to Yes in the X Output: Fault parameter window, p. 57.
This group object should be considered in conjunction with the Group number fault group object (no. 27). If there are several
group faults, this group object can be used to switch to the next number on the Group number fault object. Value 0 switches to
the next number and value 1 to the previous number.
Telegram value:
The telegram will not switch up or down any further if it encounters the highest/lowest number.
29
This group object is enabled if the Acknowledge fault messages Enable Group object "Acknowledge fault messages/Status"
parameter is set to Yes in the X Output: Fault parameter window, p. 57.
This group object is used to reset a DALI output fault. The fault may be a lamp, ballast or emergency lighting converter fault
relating to individual devices or a DALI group. The fault is only reset after acknowledgement if it has been corrected.
Telegram value:
30
This group object is enabled if the Enable Group object "Acknowledge fault messages/Status" parameter is set to Yes in the
X Output: Fault parameter window, p. 57.
This group object can be used to disable the fault messages (lamp, ballast and converter faults) for the DALI output. The
gateway will continue checking fault messages even when the messages themselves are disabled.
During the inhibit, the faults are evaluated but not sent on the KNX. The values of the group objects are also not updated.
Disabling fault messages minimizes system latency by reducing the KNX load.
When fault messages are enabled, all faults are sent in accordance with their parametrization. If a fault still exists after fault
messages are enabled, this fault is recorded and the information is sent on the KNX in accordance with the parametrization.

Function
Switch up next group fault
Dependent on parameter
1 = "switch up": Displays the next highest group number with a fault on the Group number fault group
object (no. 27).
Telegram value:0 = "switch down": Displays the next lowest group number with a fault on the Group
number fault group object (no. 27).
Acknowledge fault messages/Status
Dependent on parameter
0 = No function
1 = Reset fault messages
Disable fault messages/Status
Dependent on parameter
1 = disables fault messages (lamp, ballast and converter fault)
0 = enables fault messages (lamp, ballast and converter fault)
Note
This function can be useful e.g. for systems with emergency lighting applications for daily lamp checks which
disconnect the lamps from the DALI control line, and thus from the DALI master (gateway). In this case, the gateway
detects the loss of the DALI device and sends a ballast fault even though this is a normal operating state. If fault
messages are disabled before disconnection from the DALI control line, no fault is signaled on the gateway.
Operation can continue as normal. When the lamp checks are complete, normal monitoring can be reactivated via
the Disable fault messages group object.
