A
Auto-Replace Function
In the event that exactly one device is defective and is replaced by an
unaddressed device, the "Replace" function automatically assigns the old
short address of the previous device to the new device and subsequently
restores the settings for the device using the data stored in the I/O module
database.
C
Control Gear
Control gears are found in DALI networks as one or more components
between the power supply and one or more lamps. They are used to supply
power to the lighting and for their DALI communication. The control gears
provide the switch-on voltage and warm-up current for the lamps to prevent
a cold start, thus enhancing the power factor and reducing electromagnetic
interference.
 See "ECG."
Control Device
"Control Device" is the IEC designation for the device and includes both the
DALI (Multi)-Master Module and the active sensors.
D
DALI (Digital Addressable Lighting Interface)
"DALI" is a protocol for control of lighting control gears in building
automation, such as power supplies ("electronic transformers"), electronic
control gears (ECGs) and electronic dimmers.
The individual specifications are described in the IEC 62386 series of
standards.
 See also: "IEC 62386."
DALI-2 (Digital Addressable Lighting Interface Edition 2)
DALI-2 is a further development of the IEC 62386 series of standards that
adapts the structure of the individual parts of the standards, distinguishes
between the electrical and functional requirements on the control gears and
sets the requirements on the sensors in order to achieve a higher level of
interoperability for backwards compatibility with existing DALI installations.
DALI Short Address
Each device with a DALI interface is addressed in the network using a DALI
short address. For some multifunction devices, such as the multi-sensors,
each individual function (brightness, presence, remote control) can be
