KNX
The KNX controls, switches and monitors numerous functions in the buil-
dings. These include lighting control, maximum-demand monitoring, tempe-
rature control, emergency and standby operation, fan control, shutter/roller
blind control, timed/remote control, display/logging as well as monitoring
and reporting. Weather data can be recorded and integrated in building au-
tomation. Using various gateways, it is possible to establish an interface to
the Internet, telephone network or subsystems such as DALI, DSI or 1...10 V
control technology.
A conventional, two-core KNX control cable PYCYM (2x2x0.8 mm)
is used as the bus cable. Over 10,000 devices can be connected in 15 areas
which contain up to 15 lines.
The programming of the system is carried out with the parameterisation
software ETS (Engineering Tool Software).
Electrical equipment
All items which are used for the purposes of generating, converting,
transferring, distributing and applying electrical energy e.g. machines,
transformers, switchgear, measuring equipment, protective devices, cables
and devices.
Electrical equipment in this manual refers to dimmers, transformers,
ballasts, relays etc. which are used to operate electrical lamps.
ETS (Engineering Tool Software)
The programming of the KNX is carried out with ETS. The ETS program
makes an effective project design, commissioning and diagnostics tool for
the KNX available to the electrical installer.
Further information can be procured about EIBA or the Konnex Association.
Ballast
A device for operating gas discharge luminaires e.g. fluorescent lamps.
The ballast converts the mains voltage into the optimum operating voltage
for the gas discharge lamp. Maximum energy saving, optimum light output
and a long service life is achieved with this voltage.
Facility Management
Facility Management in the actual sense is the management of a building.
Conceptually, it means the operation, management and maintenance of
buildings. This includes the supply of power, water and lighting as well as
the servicing and maintenance of the complete building installation.
Fade Time
The fade time designates the transition time between two scenes.
Gateway
A gateway is a device which links two different systems.
Background brightness
The background brightness of DALI equipment is the brightness level which
the luminaire can set as the minimum dimming value conditioned by its
physical properties. Typical values for the background brightness of ballasts
is 1...10%.
