8. Interface / Communication
Control Input (DA/N, DA/L)
Digital DALI signal or switchDIM can be wired on the same terminals (DA/N and DA/L).
The control input is non-polar for digital control signals (DALI, DSI).
The control signal is not SELV.
Control cable has to be installed in accordance to the requirements of low voltage installations.
Different functions depending on each module.
Control input ready2mains (L, N)
The digital ready2mains protocol is modulated onto the mains signal which is wired to
the mains terminal (L and N).
switchDIM
Integrated switchDIM function allows a direct connection of a pushbutton for dimming
and switching.
Brief push (< 0.6 s) switches LED Driver ON and OFF. The dimm level is saved at power-down
and restored at power-up.
When the pushbutton is held, LED modules are dimmed. After repush the LED modules are
dimmed in the opposite direction.
In installations with LED Drivers with different dimming levels or opposite dimming directions
(e.g. after a system extension), all LED Drivers can be synchronized to 50 % dimming level by a
10 s push.
Use of pushbutton with indicator lamp is not permitted.
