Parameters for brightness sequence

DALI System... -> Configuration groups -> [x] Group name -> Colour -> Brightness sequence

DALI System... -> Configuration single devices -> [x] Device name -> Colour -> Brightness sequence

Start and stop by	Start/stop object (1-bit) Dimming object (4-bit)
A sequence is started and stopped by an object whose data format can be configured either to 1-bit or alternatively to 4-bit. Start/stop object (1 bit): A sequence is started and stopped by the "Automatic brightness run - Start/stop" object. The data format is set to 1-bit (DPT 1.010). A sequence is started by an ON telegram. A sequence is stopped by an OFF telegram. Dimming object (4-bit): A sequence is started and stopped by the "Automatic brightness sequence - Start/stop" object. The data format is set to 4-bit (DPT 3.007). A sequence is started by a "Dimming step up or down" telegram. A sequence is stopped by a "Dimming stop" telegram.

When starting in switched-off state	Switch on no reaction
When groups or single devices are switched on, the adjustment of the brightness always starts at the currently effective brightness. When groups or single devices are switched off, the start-up behaviour is determined by this parameter. No reaction: When starting, the affected group or the single device is not switched on. The gateway ignores the start of the brightness sequence. Switch-on: A fixed start value is preset as the start brightness value.

When starting in switched-off state

Switch on

no reaction

When groups or single devices are switched on, the adjustment of the brightness always starts at the currently effective brightness. When groups or single devices are switched off, the start-up behaviour is determined by this parameter.

No reaction: When starting, the affected group or the single device is not switched on. The gateway ignores the start of the brightness sequence.

Switch-on: A fixed start value is preset as the start brightness value.

Start value	preset memory value (value bef. switching-off last time) Value as before last stop
If a group or single device is to be switched on by starting a brightness sequence, the sequence starts at a configurable start value. Preset: A fixed start value is preset as the start brightness value. Make sure the configured brightness value is not below the set minimum brightness or above the maximum brightness! Otherwise, the gateway will limit the start value to minimum or maximum brightness. Memory value (value before switching-off last time): When starting, the brightness value that was active and stored internally before the last switch-off is set. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After programming with the ETS, the value is predefined to maximum brightness. Value as before last stop: The brightness sequence starts at the brightness value at which a stop was last executed during the previous brightness sequence. This parameter is available only if the parameter "When starting in switched-off state = switch-on" is configured.

If a group or single device is to be switched on by starting a brightness sequence, the sequence starts at a configurable start value.

Preset: A fixed start value is preset as the start brightness value. Make sure the configured brightness value is not below the set minimum brightness or above the maximum brightness! Otherwise, the gateway will limit the start value to minimum or maximum brightness.

Memory value (value before switching-off last time): When starting, the brightness value that was active and stored internally before the last switch-off is set. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After programming with the ETS, the value is predefined to maximum brightness.

Value as before last stop: The brightness sequence starts at the brightness value at which a stop was last executed during the previous brightness sequence.

This parameter is available only if the parameter "When starting in switched-off state = switch-on" is configured.

Sequence direction	brighter darker Toggle
The sequence direction may be either in the direction of lighter, in the direction of darker or alternating (switching the direction by toggling). When switching over, the gateway automatically changes the direction of the brightness sequence after each start.

On reaching the range limit	Stop sequence Reverse direction and continue sequence Visualise, reverse direction and continue sequence
The range of brightness adjustment is limited to the range between the configured minimum brightness and maximum brightness. This parameter defines the behaviour when the range limits are reached. Stop sequence: The brightness sequence is automatically stopped after reaching the range limits. Reverse direction and continue sequence: After reaching the range limits, the brightness sequence is automatically continued in opposite direction until it is stopped by the communication object. Visualise, reverse direction and continue sequence: When the range limits are reached, a short visualisation is carried out by the lamp and the sequence is then continued in the opposite direction. Visual feedback is provided by briefly switching the assigned DALI operating devices off and on again. The time between OFF and ON is invariably 1 second. No status telegrams are generated by the short switching process.

Total running time	0...23 h 0...59 min 10...30...59 s
After starting the brightness sequence, the step-by-step run through the predefined brightness range begins. With each step, the effective brightness value is either increased or decreased depending on the configured sequence direction and transmitted as ARC power level on the DALI line. The number of steps and consequently the brightness value increment is derived from the total running time parameterised at this point. A brightness sequence from 1% to 100% takes the specified time. The longer the total running time, the finer the brightness adjustment during the sequence and thus the resolution is. The brightness value increment is calculated by "100% : total running time [s]". If the brightness range has been limited by setting a minimum brightness greater than 1% and a maximum brightness less than 100%, the effective running time of the brightness sequence is correspondingly shorter than the configured total running time. The total running time exclusively defines the duration and the brightness value increment of a full brightness sequence. It does not specify a start or stop time. A sequence can be stopped before the total running time has elapsed.
