2.1.1 ERROR OBJECTS
DALIBOX Interface 64/32 is able to detect certain errors that may occur during normal
operation, which will be indicated through the display (section 2.8) or reported to the KNX
bus (periodically every minute), if configured.
The DALI power supply error is reported when the external power supply is
interrupted and therefore the DALI bus becomes non-functional. In such case,
the ballasts will adopt the level configured for DALI bus failure cases (see
section 2.5.1), as the ballasts have their own power supply. In case this is
interrupted too, they will obviously switch off.
During the power supply error, control actions will be ignored. Other error
types will not be reported, either. Nevertheless, the lock objects (see section
2.5.8) will be taken into account so once the error is over the corresponding
action can be performed.
The short-circuit error is reported in case the communication is interrupted
due to issues on the DALI bus. In such cases, the ballasts will acquire the value
configured for DALI bus failure cases (see section 2.5.1).
While this error persists, the following errors will no longer be notified,
due to a lack of communication with the ballasts:
➢ ECG presence error (see below).
➢ ECG and group diagnostic (see below).
The ECG presence error is notified when at least one of the already-detected
ballasts no longer responds. The detection of this error may not be immediate,
being it possible that the device takes up to one minute to report it. If a
regulation order is sent to a ballast whose presence error has not been
detected yet, the order will not be executed and one of the following will take
place:
➢ If the error is solved before having been detected, the ballast will remain
under a wrong regulation value until the next regulation order.
➢ If the error is finally detected, once it is solved the ballast will be regulated
to the last value received from the KNX bus.
