2.2 CONTROL AND OPERATION
The LiveLink LightGrid light control system can be operated manually
during operation with (wireless) push-buttons, touch panels or on the
luminaires themselves. Alternatively, the system can be controlled with
the
LiveLink LightGrid
app or the LiveLink Workplace app.
For operation with push-buttons, a distinction must be made between
two functions:
• A group push-button switches and dims a selection of luminaires
defined during commissioning.
• A light scene push-button calls up a light scene that was set up
during commissioning.
For the
group push-button
, the selection of luminaires to be operated
can consist of several luminaire groups, as defined during commis-
sioning. The luminaire groups can be assigned in different combina-
tions to several group push-buttons. Briefly pressing the button trig-
gers the switching function. If parts of the affected luminaire selection
are switched on and others are switched off when the button is briefly
pressed, their switching state is first synchronised. Whether complete
switching on or off takes place is defined during commissioning. The
luminaires can then be switched together. Pressing and holding the
button dims the luminaires. Renewed pressing and holding changes
the dimming direction.
A
light scene push-button
calls up a light level preset during commis-
sioning. The selection of luminaires to be operated can also include
several luminaire groups with differently preset light levels. All lumi-
naire groups not included in the light scene remain unaffected. The lu-
minaire groups that have been set up can be assigned to different light
scenes. Up to four preset light scenes can be created and used.
Assignment of the installed push-buttons to the light scenes or switch-
ing and dimming groups takes place during commissioning.
The
touch panel
can call up four preset or newly created scenes that
were created during commissioning. The scenes can have different
dimming levels or light levels. The light level and light colour can be ad-
justed individually with the two sliders in the middle. Individual scenes
can be saved by pressing and holding a scene button. The system can
also be switched on or off using the two buttons ("On" / "Off").
An
app with a graphical user interface
is available for operation with a
tablet; this displays the touch panel interface. All luminaires that have
been set up can be switched and dimmed with the app. All set-up light
scenes can be called up.
In addition, the app can be used to make extensive adjustments to the
system's default settings defined during commissioning (see "
Practical
tips
" below
)
.
In addition to manual operation, operation of the lighting is
controlled by
automatic functions of
the LiveLink LightGrid.
These are
• daylight-dependent control
of luminaire groups,
• presence-dependent switching on
of luminaire groups,
• presence-dependent switching off
of luminaire groups,
• presence-dependent lowering
of the lighting level of the lumi-
naire groups,
• lowering the lighting level
of the luminaire groups
depending on
the time of day
,
• circadian variation of the colour temperature
of the light
The automatic functions are based on the time setting or the evaluation
of signals from sensors. These functions as well as assignment of the
sensors to the luminaire groups can also be freely configured with the
app mentioned on this page. In particular, luminaire groups can also be
assigned to several selections regarding automatic functions.
Practical tips:
For light scene push-buttons, labelling often proves necessary in prac-
tice. Labelling can also be helpful for group push-buttons if a spatial
assignment of the luminaire groups to be operated to the position of the
installed push-button is not clear. Extensive assignments of different
selections of luminaire groups to different functions can cause com-
plex behaviour in the operation of the overall lighting – this can become
unmanageable for the user. If required, adjustments to the system con-
figuration to meet individual requirements for operating behaviour and
operating functions can be made in the app.
Every obstacle between the radio components, depending on spa-
tial conditions, worsens the radio wave propagation. The radio waves
are weakened by reflection, attenuation, diffraction and interference.
Therefore, an optimal installation location of the radio components is
decisive for an optimal radio connection, bearing in mind the maximum
radio range of the radio components.
Radio waves penetrate relatively well through simple glass (not metal-
ized), dry wood, chipboard, plastic, plasterboard etc. Very poorly pen-
etrated are e.g. all metal parts, metal walls, concrete with steel rein-
forcement, shielding fabric or shielding materials. Above all, enclosing
and shading the radio components with metal parts should be avoided.
