EIB / KNX
Device Number
Option:
A01
A02
…
A64
With this parameter, it is possible to define which DALI devices are to be
parameterised in channel A of the 1-fold DALI-Gateway.
The device numbers (A01…A64) correspond to the allocation of the
EIB / KNX names “Device A01” to “Device A64”.
Comment for the specialists: The DALI addresses which the
EIB / KNX user does not require are reduced by one, i.e. the
DALI device on the EIB / KNX with number 01 has the DALI
address 00. Device 64 has the DALI address 63. The offset
has been taken into consideration in complete application
programs with all parameters and objects as well as in the
DGS11 Software Tool. The user only needs to use device
numbers from 1 to 64.
3.4.2.1
“Normal” operating mode
In the “normal” operating mode, the connected DALI device operates as a
normal load, which can be separately switched on, switched off and dimmed
and where a brightness value can be set. As a contrast, the “dynamic”
operating mode can be parameterised with a chronological sequence, e.g. a
staircase lighting function.
Operating mode
Option:
normal
dynamic
With this parameter, you set if the DALI device should be operated in
“normal” or “dynamic” mode. For the “normal” operating mode the parameter
window shown on the previous page is displayed. A detailed description of
the dynamic operating mode can be found in section 3.4.2.2.
Brightness value when turned on
Option:
last brightness value
100%
90%
…
20%
10%
min. physical brightness
This parameter defines the brightness with which the DALI device is
switched on as soon as an ON telegram is received.
If a value which is outside the minimum and maximum dimming value limits
is to be set during operation, the brightness will be limited to the maximum or
minimum dimming values.
If for example the device is at a brightness value which is not equal to the
switch ON value and it receives an ON telegram, the parameterised switch
ON value is set.
The “last brightness value” parameter setting has the effect that the device
switches on with the brightness value which it had before the OFF command
was received. The last brightness is stored in the ballast and is not changed
with the central commands (Broadcast commands). The minimum physical
brightness of DALI equipment is the brightness level which the luminaire can
set as the minimum dimming value conditioned by its physical properties.
Typical values for the minimum physical brightness of ballasts are 1...10%.
