﻿Acknowledgement prevents the simple confirmation of a DALI busy by the object "Status - DALI busy".

*Checkbox activated*: DALI system identified, it indicates "db" on the 7-segment display on the front of the device. In addition, the 1-bit object "Status - DALI busy" is available, which signals the load also by means of an ON telegram. To confirm this status message, an ON telegram must be received by means of the 1-bit object "Acknowledgement - DALI busy". Only after acknowledgement has taken place does the gateway reset the status in the object "Status - DALI busy" with an OFF telegram. If the load in the DALI system remains high after acknowledgement, the gateway sets the status again so that another acknowledgement is required.

*Checkbox deactivated*: The "DALI busy" status is activated. As soon as the gateway identifies a busy DALI system, it indicates "db" on the 7-segment display on the front of the device. In addition, the 1-bit object "Status - DALI busy" is available, which signals the load also by means of an ON telegram. Confirmation of this status message is not required. The gateway automatically revokes the status with an OFF telegram as soon as the load of the DALI system returns to normal.
