Enable function "Partial failure"
Options:
The Partial failure function allows lighting to be controlled regardless of a failed component.
•
Yes: The Partial failure function is enabled. Based on a defined number of failed lamps, other ballasts
or groups can still be controlled via an external group object, Activate Partial failure/Status, or directly
in the DALI output. How the lamp reacts on partial failure is defined in the Functions parameter
window in the group or ballast.
•
No: The Partial failure function is not enabled.

Yes
No
Selection of Yes option:
Dependent parameters:
Partial failure criterion:
The following parameters define what is counted as partial failure. The whole DALI output is taken
into consideration. The criteria are OR-linked. The reaction to a partial failure is triggered as soon
as one criterion is met.
DALI voltage fault
Options: Yes
No
•
Yes: A DALI voltage fault will trigger the reaction to partial failure. A DALI voltage fault is e.g. a
gateway supply voltage failure or a DALI short circuit. Note that in this case it is not possible to
communicate with ballasts or groups on the DALI output which is down. However, the partial
failure can be forwarded via the Activate partial failure/Status group object.
•
No: A DALI voltage fault is not counted as a partial failure.
