Project design and programming
With this function, the dimming actuator follows the brightness value which it
has been assigned by a light controller. It can thereby be integrated in a
constant lighting control function.
An ON telegram to the object "Telegr. switch" always activates the slave
function. The dimming actuator then continually follows the brightness value
which it is assigned by the object "Slave brightness value".
The dimming limits from the parameter window "A: Value" are adopted. The
object "Status brightness value" does not send a status response when the
slave function is active.
If the slave function and the lighting should be switched on/off with a rocker,
the switch object of the rocker should be linked with the objects "Telegr.
switch" and "Slave active / inactive" of the actuator.
On receipt of an OFF telegram, the slave function is deactivated and the
lighting is switched off.
Behaviour of the function "Slave mode" during and after voltage failures:
Bus voltage failure
Bus voltage recovery
Supply voltage failure
Supply voltage recovery
Parameter: "If slave mode is active: reaction on ..."
It can be set via these three parameters how an output reacts during active
lighting control if the following telegrams are received:
Switching on Receipt of the telegram value "1" at the object "Telegr. switch"
Relative dimming Receipt of a telegram at the object "Relative dimming"
Brightness value or Receipt of a telegram at the object "Brightness value" or "Call preset
preset ..."
It can be set which effect the receipt of the telegram has on the active slave
mode:
In the setting "no reaction", the receipt is ignored.
In the setting "Slave mode can be deactivated", the slave mode is
deactivated. It can be reactivated by an ON telegram.
Behaviour of the output as defined in the "General"
parameter window. Slave mode is deactivated.
Status of slave mode as before bus voltage failure;
brightness remains unchanged until the receipt of the
first brightness value.
No function
Status of slave mode can be parameterised
