choosing the dimming time duration for dimming on or dimming off, the time is equal to this input value multiply
2 seconds, and the maximum input time is 255s.
Parameter “Switch on via OBJ “switch” with”
It is used to select the brightness value is the last one or the preset one when using the switch mode to switch
on the luminaries. Options:
Preset brightness value
Last brightness value
The option “Preset brightness value” means the brightness value is the preset value when switching on the
luminaries by switch mode. When the brightness low threshold value is greater than the switch preset value, the
brightness value of the luminaries is the low threshold value after switching on; when the switch preset value is
greater than the high threshold, the brightness value is the high threshold one after switching on. The high and low
threshold of the brightness are shown in the parameter window “CH X dimming”, see Fig. 6.5.
The option “Last brightness value” means the brightness value is the last status’ value which is not equal to 0.
If the behavior of switching on the luminaries in switch mode after the BUS reset, and the luminaries during BUS
reset are off, so the brightness value is the default brightness value 128; Other cases, the brightness value is the
last status’ value which is not equal to 0 on switching mode.
Parameter “Preset switch on brightness(1%...100%)”
It is used to set the brightness value when switch on the luminaries in switch mode, with the setting range
1%~100%.
Parameter “Reaction on receipt of switch on value”
It shows the time duration to switch on the luminaries in switch mode. Options:
Dimming on
Switch on softly
The option “Dimming on” means the switch dimming time is the input time multiplies 2. Then option
“Switch softly” means the default dimming time is 4s.
Parameter “Reaction on receipt brightness value”
It is used to set the brightness value in the brightness dimming mode. Options:
Dimming on
Switch on softly
The option “Dimming on” means the brightness dimming time is the input time multiplies 2. Then option
“switch softly” means the default dimming time is 4s.
