How does 1 button dimming function?
Switch and dim functions can be controlled completely using a single push button. With each long
operation alternate BRIGHTER or DARKER dimming occurs, or with short operation alternate
switch on or off occurs.
If the
Switch
group object = 0, a BRIGHTER telegram is sent at all times. In order to evaluate the
switch feedback of the actuator, the Write flag of the
Switch
group object is set.
The following table shows the function in detail:
Switch group object value
Value of the last dimming telegram
Reaction of the dimming actuation
(sends dimming telegram)
OFF
DARKER
BRIGHTER
OFF
BRIGHTER
BRIGHTER
ON
DARKER
BRIGHTER
ON
BRIGHTER
DARKER
The advantage of the
Only dimming
function is that no distinction is made between short and long
operation. Thus, the Dim telegram is initiated immediately after operation. It is not necessary to wait
for a long operation.
How does 2 button dimming function?
If 2 button dimming is required, the functions of the individual buttons should be set with the
parameters
Reaction on short operation
or
Reaction on long operation
, e.g. ON or BRIGHTER.
The user thus has the choice of the buttons to be combined with one another, e.g. to dim a lighting
group or the function that the individual buttons should perform in this case.
Furthermore, two inputs are required for 2 button dimming, e.g.
Input a
with short operation for ON
and long operation for BRIGHTER.
Input b
with short operation for OFF and long operation for
DARKER.
Selecting the
Dimming and switching
option in the
Function Dimming
parameter unhides the parameters

,
On short operation: Switch
and
On long operation: Dimming direction
in the

Options:
0.3/0.4/0.5/0.6/0.8/1/1.2/1.5/2/3/4/5/6/7/8/9/10 s
This defines the time period T
L
after which an operation is considered a "long" operation.
