With this communication object, it is possible to disable the fault messages (lamp, ballast and converter fault) of the DGN/S. If
the fault messages are inhibited, the DGN/S will continue to undertake fault message examination regarding lamp, ballast and
converter faults.
During the inhibit, the faults are evaluated but not sent on the KNX. The values of the communication objects are also not
updated.
The latent time of the system can be minimized at low KNX load when the fault messages are inhibited.
When all error messages are enabled, the malfunctions will be sent in accordance with their parameterization. If a fault still
exists after enabling of the error message, this fault is recorded and the information is sent on the KNX in accordance with the
parameterization.

Note
This function can, for example, be useful for systems with emergency lighting applications for daily checking
of the lamps of the DALI devices by the DALI control line and thus disconnect them from the DALI master
(DGN/S). In this case, the DGN/S detects the loss of the DALI device and sends a ballast fault even though
this is a normal operating state. Should the fault message be disabled before separation from the DALI
control line, no fault is reported on the DGN/S. Operation can continue as normal. After checking the lighting
equipment, normal monitoring can be reactivated via the error message communication object Disable
sending of fault alarm.

This communication object is always enabled. Using this communication object, with the appropriate parameterization the
various dimming times can be modified via KNX. The flexible time does not relate to central telegrams but rather exclusively to
group or scene telegrams. There is only one flexible dimming time per Gateway that acts on all parameterized flexible
dimming times.
Dimming time for switch on and off value
Dimming time for brightness values
Dimming time for relative dimming (dimming speed)
Dimming time for slave brightness values
Staircase lighting time
Time duration of the basis brightness for staircase lighting
Transition time in sequence operation
Telegram value:
Flexible time is used directly after download. If no flexible time is used before the value is 0 s.
The communication object value is set by the parameterized value after bus voltage recovery. A value set via the bus before-
hand is overwritten and is lost.
