Commissioning
This ensures that the state before the first preset can be re-
established. A new preset value is again saved if beforehand the
preset has been recalled with the function restore value before first
preset call.
The reaction to a preset command with active light control can be
parameterised in the parameter window
The parameterisation undertaken in this parameter window X: Presets
is only transferred to the Light Controller during a download, if in the
parameter window
with standard value during download has been set to yes.
In the following the preset functions are described using the parameters for
Preset 1 and 2. The specifications apply for presets 3 and 4.
Reaction on preset 1 (telegr. value 0)
Options: 100/99...1/0 % (switch off)
restore value before first preset call
reset to parameterised value before preset 2
This parameter determines how the output reacts with the recall of preset 1,
i.e. meaning that object Call preset 1 and 2 receives a telegram with the
value 0. A fixed brightness value can be recalled.
The following functions can be selected as further selection options:
•
restore value before first preset call: The state of the output which
existed before the preset was first called after a download recall of
preset 2, 3 or 4 is restored.
If for example, lighting control via slave operation was active, this is also
reactivated and executed. The state is only saved with the first preset
recall. Further preset recalls do not initiate a renewed save. Only after
a recall restore value before first preset call is a new brightness value
stored which corresponds with the state before a preset is called.
•
reset to parameterised value before preset 2: Preset 2 resets to the
parameterised value it had before it was changed by the user. This can
be advisable if preset 2 can be stored via the bus, see below.
Note
With the parameterisation restore value before first preset call or reset to
parameterised value before preset 2, saving of the preset concerned has
no effect. The saved value is not recalled but rather the parameterised
function is undertaken.
