2.2 New in L-DALI 3.2
This section describes the major changes and new features. For a full list of changes refer to
the Readme file.
New Constant Light Controller Modes
The constant light controller application offers some new Modes:
The modes CONTROL, REGULATOR and PRESENCE are now available in
variations with the extension AUTO. In these modes any active override will be
automatically relinquished when the room enters “unoccupied” state. This allows to
reactivate automatic mode when the room is unoccupied. The light will be switched off
and – if necessary – switched on when someone enters the room.
As a special variation of the AUTO modes, modes with the extension BEDROOM are
available. In this mode the manual override is only relinquished when the lights are
switched on. This ensures lights are switched off when the room is unoccupied, but stay
off when commanded to off manually.
The mode AMBIENT allows switching on and off lights depending on the measured
lux level. It is therefore suitable for decorative lighting (facade illumination, shop
window lighting, floor lighting, etc.).
The modes CONTROL and REGULATOR (incl. all variations) now consider the
configured Unoccupied Level when switching off, similar to the mode PRESENCE. This
allows dimming down to a configured level when the room is unoccupied instead of
switching off. Typical applications are a reception area or similar areas where the light is
never turned off completely.
Note:
If the an LDALI-10X device was not shipped with firmware 3.2 the new modes are only
available after the datapoint configuration was up- and downloaded again using the LINX
Configurator.
Further information on the constant light controller modes can be found in Sections 8.2.8.3
and 8.3.5.2 and for the behavior when switching off in Sections 8.2.8.8 and 8.3.5.7.
Overriding the Constant Light Control with DALI Buttons
When using internal manual bindings the constant light controller now detects when one of
the groups it controls is dimmed by another DALI master. Such and override is interpreted
similar to an override using the CEA-709/L
ON
M
ARK
or BACnet interface. Typically such a
DALI master is a DALI push-button coupler or a similar device for manual control of DALI
lights. As these devices directly control the DALI groups, they allow local operation of the
lights independent of the L-DALI.
Constant Light Controller Bindings across Channels
DALI groups and DALI sensors can be linked to constant lights controller instances using
internal bindings across DALI channels (see Sections 5.3.2 and 7.6).
Support for DALI ballasts with Colour Control
In the LDALI-10X models DALI ballasts of type “colour control” (device type 8) can be
controlled. The LDALI-10X supports devices with changeable colour temperature and with
coloured light. The latter can be used for effect lighting, while the previous can be used to
simulate the colour temperature of the sun during the course of a day (warmer white during
morning and evening, cooler white at noon).
