Chapter 1 Summary
KNX Universal Dimming Actuator,1/2/4-Fold (hereinafter referred to as Dimmer) has 1/2/ 4 output
channels, and it can connect with dimmable lamps (such as incandescent lamps, halogen lamps,
energy-saving lamps, LED, etc.), and you can dim, preset scene, switch these lamps or other operations
via the bus. In addition, as well as KNX Data Secure.
This dimmer is a modular installation device for fast installation in the distribution board on 35 mm
mounting rails to DIN EN 60 715, the output adopts screw terminal to realize electrical connection. Bus
connection is directly connected via KNX terminal, the additional power supply is not required except
KNX bus.
You can build the various scenes with the dimmer, such as watch movie, entertainment, dinner and
rest, and so on; its brightness value can be set as any value (1-100%); it is able to set the duration time
to dim up or down to the target brightness and the gradual speed to extend the luminaries life and save
energy.
The physical address assignment and parameter settings can be used with the engineering tool
software ETS (version ETS5 or above) with the .knxprod file.
In use you need to note the type of connected electrical load, thus reasonable select them and
note their technical performance. If the technical performance of the selected load is not consistent
with the technical performance of the dimmer, it is possible to affect the dimming effect.
The manual provides detailed technical information about the dimmer, including installation and
programming details, and explains how to use the dimmer in conjunction with examples in actual use.

Note:
It is not permitted to connect inductive and capacitive loads together at the same output.
However, mixing of loads such as capacitive + resistive loads or inductive + resistive loads is allowed
to connect, but power reduction needs to be considered. It is more advisable to connect the same type
of loads for an output.
The max. load capacity depends on the surge current and power loss of the lamp, these types of
lamp will cause large heating and high surge current in leading edge mode, especially LED lamp, so it
is not recommended to drive LED in leading edge mode, make sure the connected lamp do not trigger
over-load or over-heating protection.

2.2.Operation mode
Dimmer system is dimming in leading or trailing edge.
1.Dimming in leading edge:
Explanation of the dimming system: turn off dimmer in leading edge and turn on in trailing edge. As
shown in the following figure, no voltage input from zero point until dimmer is turned on. It is suitable
for inductive loads.
2.Dimming in trailing edge:
Explanation of the dimming system: turn on dimmer in leading edge and turn off in trailing edge. As
shown in the following figure, dimmer will be turned on the zero-crossing point, during this moment, the
voltage is very low and there is no inrush current to the load. In this way, there is no minimum load
requirement, so that allows for better performance of a single lighting or a very small load and extends
the life of the lamp, as well as reduce the interference to the power grid. It is suitable for resistive or
capacitive loads.

Chapter 4 Project Design and Programming
General function
General function includes device In operation setting, central control (Switch, Dimming), safety
function, as well as manual operation and output indication function.
In addition, central control function only applies for 2/4-Fold Dimmers, and it is not supported by
1-Fold Dimmer.
Output channel
There are 1/2/4 output channels according the product type, support to switch, relative
dimming/absolute dimming, feed back the status of switch, brightness and the abnormal status
(short-circuit, over-voltage, over- temperature and operating voltage failure), as well as reset behaviour
after download/bus failure/bus recovery. Individual or parallel outputs can be selected, and the parallel
can expand the load capacity, which only applies for 2/4-fold.
Load types and dimming curves can be independently configured, as well as extension functions
including Staircase lighting, Flashing switch, Delay switch, Scene, Threshold, Forced operation, Safety
operation and Operation hours counter.
For output function, the definition of function priority: Manual > Forced > Safety > other functions,
after exiting higher priority, the next priority action needs to be executed.

Chapter 5 Parameter setting description in the ETS
5.1.KNX Secure
Dimmer is a KNX device that complies with the KNX secure standard. That is, you can run the
device in data secure mode.
Fig.5.1 (1) "KNX Secure" parameter window
The device with KNX secure will be displayed notes on ETS, as shown as Fig.5.1(1).
If secure commissioning is actived in ETS project, the following information must be considered during
device debugging:
It is essential to assign a project password as soon as a KNX Secure device is imported into a
project. This will protect the project against unauthorized access.
The password must be kept in a safe place – access to the project is not possible without it (not
even the KNX Association or device manufacturer will be able to access it)!
Without the project password, the commissioning key will not be able to be imported.
A commissioning key is required when commissioning a KNX Secure device (first download). This
key (FDSK = Factory Default Setup Key) is included on a sticker on the side of the device, and it must be
imported into the ETS prior to the first download:
On the first download of the device, a window pops up in the ETS to prompt the user to enter the
key, as shown in Fig.5.1 (2) below.
The certificate can also be read from the device using a QR scanner (recommended).

KNX/EIB KNX Universal Dimming Actuator,1/2/4-Fold
14
Fig.5.1(2) Add Device Certificate window
Alternatively, the certificates of all Secure devices can be entered in the ETS beforehand.
This is done on the "Security" tab on the project overview page, as shown in Fig.5.1(3) below.
The certificates can be also added to the selected device in the project, as shown in Fig.5.1(4).
Fig.5.1(3) Add Device Certificate
Fig.5.1(4) Add Device Certificate
There is a FDSK sticker on the device, which is used for viewing FDSK number.
Without the FDSK, it will no longer be possible to operate the device in KNX Secure mode
after a reset.
The FDSK is required only for initial commissioning. After entering the initial FDSK, the ETS will

KNX/EIB KNX Universal Dimming Actuator,1/2/4-Fold
15
assign a new key, as shown in Fig.5.1(5) below.
The FDSK will be required again only if the device was reset to its factory settings (e.g. If the device
is to be used in a different ETS project).
Fig.5.1(5)
Example:
If this application in the project needs to be tried with another device, it is no longer the original
device. When the application is downloaded to a new device, the following prompt will appear on the
left of Fig.5.1(6), click yes, the Add Device Certificate window will appear, then enter the initial FDSK of
the new device, and you need to reset the device to the factory settings (it is not required if the device is
still factory default; If it has been used, it will be required to reset, otherwise the following error
message will appear on the right of Fig.5.1(6)), and then the device can be successfully downloaded
again.
Fig.5.1(6) Example
Whether the device is replaced in the same project, or the device is replaced in a different project,
the processing is similar: Reset the device to the factory settings, then reassign the FDSK.
