KNX-DIM21 SATEL The KNX-DIM21 module is a universal two-channel dimming KNX actuator that allows stepless control of light sources up to 300 W per channel. The light can be turned on / off, dimmed down (darker) / dimmed up (brighter), set by using a predefined scene or another function via the KNX bus. - Page 5 SATEL KNX-DIM21 – green, – red) – see Table 1.

4. Connect a computer running ETS program to the KNX bus and configure the module. To configure the module, you will require a computer running the ETS program version 5.5 or newer, provided with USB or Ethernet (TCP/IP) connector. The SATEL ETS application file, which can be downloaded from www.satel.eu/ets, must be imported into the program. -

Page 10: Function Priorities
KNX-DIM21 SATEL Function priorities The order in which the functions can change the status of channels in the module depends on what priority the given function has. The value forcing function has the highest priority, whereas the switching and dimming functions have the same priority (see Fig. 5). A higher... -

SATEL KNX-DIM21 The lower priority functions cannot control the channel state as long as a higher priority function is active. In the ETS program, you can define the minimum and maximum limit value of brightness that can be set for the channel (see “Value limits”). If the brightness value defined for a function is higher than the maximum one or lower than the minimum one, the corresponding limit value will be set for the channel. -

- Page 14 KNX-DIM21 SATEL Selecting the load type will also define the channel operation mode: – load controlled by leading edge – suitable for resistive and inductive loads. Control signal switches on the load when voltage between lines L and N is higher than 0 (during the sine wave), and switches it off when the voltage is 0 V.

Adjustment of the characteristic results in bending the lighting characteristic curve, however changing the light source brightness is perceived by the human eye as linear.
