ERROR OBJECTS
DALIBOX Broadcast 6CH / 4CH is able to
detect certain errors
that may occur during
normal operation, which will be indicated through the on-board LEDs (please refer to
ANNEX I. Error indicators). Moreover, in case of having parameterised it, these errors
can be notified to the KNX bus too.
Blocking errors (short-circuit and lack of power supply) will interrupt all actions,
including timed actions
. Other errors will not interrupt them – they will still be
executed by all connected ballasts that do not present errors.
2.2.5.1
SHORT-CIRCUIT ERROR (DALI ERROR)
The
short-circuit error
(or
DALI error
) is reported in case the communication is
interrupted in the output channel, due to issues in the DALI bus. In such cases, the
ballasts will acquire the value configured for DALI bus failure cases (see section 2.2.1).
While this error persists, the following errors will no longer be notified
, due to a
lack of communication with the ballasts:
Ballast Error
Lamp Error
Open Circuit Error
Ballast Overload Error
2.2.5.2
POWER SUPPLY ERROR
This 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 2.2.1), as the ballasts have their own
power supply. In case this is interrupted too, they will obviously switch off.
During the power supply error, the channel will not respond to control actions. Other
error types will not be reported, either. Nevertheless, the lock objects (see section
