•
DALI format (1...15): The values received via the group object are interpreted by the gateway
as a discreet numeric value, which is directly converted to the DALI value for the fade time.
These values comply with the specified transition times according to the DALI standard. For
example, the value 0 means immediate activation of the value, and 15 corresponds to 90.5
seconds. For details, please refer to the description of the Dimming/fade time (DALI format
(0...15)) group object.
•
KNX format time 100 ms: The gateway interprets the values received via the group object as
a 100 ms value and directly rounds it to the nearest DALI value if required (see description of
Flexible dimming time group object). For details, please refer to the description of the
Dimming/fade time (time 100 ms) group object.
•
KNX format time 1 ms: The gateway interprets the values received via the group object as
a 1 s value and directly rounds it to the nearest DALI value if required (see description of
Flexible dimming time group object). For details, please refer to the description of the
Dimming/fade time (time 1 s) group object.
The fade time is specified as the time required to change the lamp power from the current
brightness value to the required target brightness. If a lamp is switched off, the preheat and ignition
time are excluded from the fade time.
If the gateway supply voltage fails, the set dimming time is retained.
If the KNX bus voltage fails, the dimming time is lost and must be reset.
The default value is set at 2.0 s until a new value is received.
