Function introduction
The dimmer with LED constant voltage drive can drive LED directly, has four
channels, each channel is independent.
The output can connect with some big power dimmable LED lights. These LEDs can
be switched, dimmed, recall scene or other operations via the bus.
The devices adopt PUSH terminals to achieve electrical connection; the
connection to the EIB/KNX bus is established via a bus connecting terminal.
The input need connect a 12V-36V DC operation voltage. The following list
provides a functional overview:
☆Switching the LED light
☆Relative dimming
☆Absolute dimming
☆Status report, error report
☆Setting 15 scenes
☆Staircase lighting function
☆Bus recovery (or reset) function
☆Preset value and modify preset value functions
☆Switch/relative dimming via manual buttons
The above function of parameters to configure and use are described in the
chapter 5. The device has own database file. There is added a manual operation
function in the normal dimming mode, it is invalid in the staircase lighting
mode. Switch via a short operation of manual buttons, relative dimming via a
long operation, and in the case of the bus voltage fail the manual operation
is invalid.

Application Programming
Introduction
It is able to set different parameters to every output channel, and control
various targets by modifying the setup of the internal parameters.
Switch
The output can be switched ON or OFF by 1 bit data. It is able to set the
brightness value as the last one or a defined one (1%-100%) when switching on
the luminaries. It is able to set a delay time (changing time) to dim UP the
luminaries or dim UP gradually in the default period. When receiving the OFF
message, the dimmer will be switched off immediately, or dim DOWN gradually
after a delay time (changing time) or in the default changing period.
Relative dimming
4 data bits control: the relative dimming command means it is possible to dim
UP or DOWN to the needed brightness value during the set brightness threshold
range. It is only valid to dim UP when the brightness value is smaller than
the low threshold value and dim DOWN when the brightness value is greater
than the high threshold value. It is also able to set whether to switch on the
luminaries by the message “dim UP to a certain value” when the output is 0 by
this function. The relative dimming is used to control the relative changes
of the brightness by 4 data bits: the lowest 3 bits are controlling-bit and
the highest bit is—– “1” means dim UP, “0” means dim DOWN.
Explanation of setting relative dimming: (1-7: dim DOWN; 0-8 remain unchanged
(stop dimming); 9-15 dim UP)
Parameter | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
---|---|---|---|---|---|---|---|---|
Dim DOWN | Unchange/stop dimming | 255 | 128 | 64 | 32 | 16 | 8 | 4 |
Parameter | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
Dim UP | Unchange/stop dimming | 255 | 128 | 64 | 32 | 16 | 8 | 4 |
Absolute dimming
8 data bits control: it is able to dim to the needed brightness value by
changing the brightness parameters.
The setting of the parameters is similar as relative dimming with the
brightness value range: one low threshold value and one high threshold value.
And it is not allowed to change the brightness value beyond the set range, the
max. range is from 0 to 255. This function offers the possibility to dim UP
or DOWN to 0 gradually to the target value by setting the delay time or the
default time.
The high and low threshold value limits the total output of the dimmer; any
brightness value beyond the range is not valid.
When the output is 0, it is able to set switching off the luminaries or
remaining to a lower brightness value;
and also in this status it is optional to switch on the luminaries by
receiving the message “absolute dimming”.
Status Report
1 data bit: the dimmer offers the possibility whether sending the latest
brightness value report of the controlled target and the changed report of the
switch status to the BUS. Scene 8 data bits control: the dimmer offers 15
(1-15) scenes for selection. It is possible to set ONE brightness value and
the gradual change time of ON for each scene. After setting, it is easy to
call any favorite scene. 1 in the highest bit of the scene command it means
“saving” command, to save the current brightness value to the relevant scene.
Preset Value
The dimmer can preset scene, the object directly through 1bit data to transfer
the preset scene or through1bit data to let favorite scene to replace original
preset scene. There are two preset values per output, there are two brightness
values can be transfer for each preset value. Such as in theater, we need a
relatively bright lighting effect when coming in, we can through transfer the
first brightness value to be achieved this effect, when the movie starts
playing, we need a relatively dark lighting effect, we can through transfer
the second brightness value to be achieved. We can return to the previous
brightness value when the movie ended.
Staircase Lighting Function
The dimmer offers the function of staircase lighting control besides the
normal lighting control.
The staircase lighting function serves to switch off the lighting directly
until dimming DOWN to 20% of the brightness value after a set period. It is
able to set the brightness of the luminaries, the duration of the light ON,
the time to dim down to 20% separately.
In this function, it uses 1 data bit control the targets directly by setting a
permanent fixed value to the output of the staircase luminaries.
The steps of staircase lighting control: the staircase luminaries will be
switched on for a certain time (this time can be set) if the controlled target
receives the message of “1”; these luminaries will be switched on again when
receiving another message “1” during this period. The luminaries will be
switched off when they are dimmed down to 20% of the brightness value (the dim
down time can be set) after this period, or switch off the luminaries by
sending message “0” to the controlled target. The luminaries will be off after
dimming down to 20% when receiving the message “0” (the same dimming down time
as above). When enabling the function “On reception switch OBJ=0 switch off”,
it is able to use the function “switch off” to turn off the output in the
status of “permanent on”, or change the status from “switch on” to “permanent
on” (message “1” means ON, “0” means OFF).
Reset
When the BUS is power off, all the outputs are switched off; the current brightness value will be saved to the memory of the dimmer. When the BUS voltage is recovered, the brightness status may be the last brightness value, or the preset brightness value.
When the BUS is power off, it may have the following situation occurring:
In the normal mode, 2 optional behaviors after the BUS voltage recovery are: the last brightness value before power off, or the set value.
In the staircase lighting mode, the behavior after the BUS voltage recovery
is: ON or OFF. No output when itis OFF; start the behavior “switch=1” when it
is ON.
When the BUS is power off, all the outputs are switched off; the current
brightness value will be saved to the memory of the dimmer. When the BUS
voltage is recovered, the brightness status may be the last brightness value,
or the preset brightness value.
When the BUS is power off, it may have the following situation occurring:
In the normal mode, 2 optional behaviors after the BUS voltage recovery are:
the last brightness value before power off, or the set value.
In the staircase lighting mode, the behavior after the BUS voltage recovery
is: ON or OFF. No output when it is OFF; start the behavior “switch=1” when it
is ON.
