C
Control Gear (electronic ballast, ECG)
"Control Gear" is the short designation for "electronic control gear" (ECC).
In DALI networks, control gear is implemented as one or more components
between the network power supply and one or more lamps.
The control gear is used for power supply for the lighting and for
communication with DALI. The control gear 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.
Control Device
"Control Device" is the IEC designation for the DALI-(Multi)-Master. This
term also denotes the active sensors.
D
DALI
"DALI" is the acronym for "Digital Addressable Lighting Interface", a
protocol for control of lighting devices and equipment in building
automation, such as switched-mode power supply units ("electronic
transformers"), electronic control gear (ECG) or electronic dimmers.
Specific definitions are elucidated in the IEC 62386 series of standards.
Refer also to "IEC 62386".
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
multisensors, each individual function (brightness, presence, remote control)
can be assigned a dedicated DALI short address, enabling the function to be
specifically addressed.
E
Easy Mode
In the "Easy" mode, DALI devices linked to the system are represented in
binary form the process image with two bits each. These two bits
correspond to the button functions (ON/OFF, DIMMING) and are
implemented in the DALI-Multi-Master module. The status is queried in
cycles.
