The parameter window
properties of the slave output are parameterised, e.g. it can be
parameterised if the slave output in the Light Controller is directly
(internal) or externally controlled via a communications object.
Hereby other ABB i-bus
dimmers can be integrated as slaves into the constant lighting control.
The required brightness value is provided by the master in the Light
Controller via the communication object Brightness value of slave.
The brightness in slave mode can be limited by brightness values.
Parameterisation is undertaken in the parameter window
•
Staircase light: The lighting is switched off or dimmed down slowly
automatically after a predetermined time. The basis brightness is the
brightness to which the output is set after the staircase lighting time
has timed out. This basis lighting time can also be not equal to zero.
Example
This function can ensure, e.g. that a basis brightness level always
exists in the hallways in senior citizen homes or hospitals. Only after
someone has entered the hallway (detected by a presence detector)
will maximum brightness switch on. It is dimmed down automatically
to the basis brightness after the staircase lighting time has timed out
and when nobody is in the hallway.
Setting of a prewarning before the staircase lighting is switched off is
possible via dimming and/or by a 1 bit object. With a 1 bit object any
desired optical indication or an acoustic signal can be implemented as
a prewarning feature.
With the option Staircase light no light control is possible with this output.
The output operates as a normal 1-10 V Switch/Dim actuator or
a staircase lighting timer.
The special properties of the staircase lighting function are defined in

Note
These three additional functions, Control, Staircase Lighting and
Slave mode, can assume three operating states:
Additional function is not active: The additional function has been
deactivated via its object Select additional function (telegram
received with value 0). In this state the Light Controller acts like
a normal Switch/Dim actuator. ON commands do not cause the
function to start. Only after a telegram with the value 1 has been
received on the object Activate additional function is it possible to
start the additional function.
Additional function is in standby mode: The additional function
is active but has however been ended, e.g. by the OFF command.
The additional function still remains active in the background and
starts again after an ON command. The Control controls, the
Staircase light runs and the Slave mode executes the telegram of
the master.
Additional function runs: The Control controls, the Staircase light
runs and the Slave mode receives brightness values from the
master. With corresponding parameterisation of the switching
commands the additional functions can be set to standby mode.
