Project design and programming
The upper and lower dimming limit set here also apply when retrieving
presets and 8-bit scenes as well as in the staircase lighting function and
slave mode. If a brightness value is retrieved which exceeds the upper
dimming limit, the upper dimming limit is set.
If a brightness value is received during a dimming process, the process is
first stopped and then the new brightness value is triggered.
The presets are used to retrieve preselected brightness values via 1-bit
telegrams. Further information about the function can be obtained in section
3.2.
After a failure in the supply voltage and after programming the device, the
parameterised preset values are restored.
The parameters are identical for preset 1/2 and preset 3/4.
Parameter: "Reaction on preset1 (telegr. value 0)"
This parameter defines how the output behaves when retrieving preset1, i.e.
when object "Call preset 1/2" receives the telegram value "0". A fixed
brightness value can be retrieved. One of the following functions can be
selected as a further option:
"restore old value" recreates the brightness before the last retrieval of
preset2. If the lighting control function or slave mode were active, they are
also reactivated.
"reset to parameterised value" resets preset2 to the parameterised value.
This can be advisable if the preset can be stored via the bus (see below).
Parameter: "Reaction on preset2 (telegr. value 1)"
This parameter defines which brightness value is set on retrieval of preset2
(= object "Call preset 1/2" receives telegram value "1").
Parameter: "Preset values 1/2"
This parameter sets whether the dimmer jumps to the preset value as
quickly as possible or whether the dimmer dims to the preset value using the
transition time.
