General Detect Ballasts [EIS 1; 1-bit switching]:
To be able to correctly detect a fault in a
ballast, the DALI-Gateway must identify all the connected DALI devices and thereby know the
number of DALI devices per channel that need to be monitored. This identification process
runs independently and fully automatically in the background if it has been initiated by this
communication object. An automatic detection, e.g. after a bus or mains voltage recovery
does not take place. After approx. 60 seconds, all the DALI devices are detected and the
failure of a ballast can be correctly established.
The activation should be carried out directly after commissioning or when extending or
reducing the DALI devices. The DALI devices are continually monitored, regardless of
whether the lamp is activated or deactivated. The DALI devices must be installed properly
and supplied with operating voltage if necessary.
Telegram value
“1”: Start ballast detection process
"0": no function
Note: The same function as for the object “Detect Ballasts” can be manually triggered if the
test button on the DALI device is pressed for longer than 5 seconds.
