Touch DIM
®
: lighting control without a controller and dimming without a control line
The Touch DIM
®
function in the DALI ECG family makes
it possible to dim and switch the control gear directly
with line voltage at the DALI control terminals. There is
no longer any need for a separate controller as the ECG
itself acts as the controller. By using DALI to 1…10 V
converters it is possible also to control 1…10 V ECGs via
Touch DIM
®
. The Touch DIM
®
function is characterized
in particular by protective soft starting, precise setting of
the required light value, manual storage of the switch-on
value by double-clicking or switching on at the last dim-
mer value and automatic restoration of the last state after
a power failure.
In conjunction with Touch DIM
®
sensors it is possible to
provide daylight-dependent and presence-dependent
lighting control, and with the 2-channel radio switch +
associated radio receiver module all Touch DIM
®
compat-
ible electronic control gear can be controlled. Both radio
components are absolutely maintenance-free. Up to 30
radio switches can be easily saved and deleted in each

receiver module with one click. Thanks to innovative
induction technology, batteries are not needed to power
the transmitter module in the radio switch. For realizing of
big Touch DIM
®
installations or long line length the usage
of a DALI Repeater is recommended. Thereby the signal
of the push button will be transformed in a DALI-signal. In
this way the usage of push button control is possible for
all DALI-products.
