KNX / DALI Gateway N 141/02
Product and functional description
The KNX / DALI gateway N 141/02 is a 4 MU wide, DIN-
rail mounted KNX device with one DALI interface to
which up to 64 DALI actuators (e.g. DALI ballasts) can be
connected to. It is not allowed to connect DALI sensors to
the DALI interface of the N 141/02.
DALI (Digital Addressable Lighting Interface) is a
bidirectional communications interface in accordance
with IEC 60929, whose specification has been defined by
manufacturers of electronic ballasts. It not only enables
the receipt of e.g. switching and dimming commands but
also the sending of status information such as the failure
of a lamp or the report of a detected error in the
electronic ballast. According to IEC 60929 up to 64 DALI
devices can be connected to a DALI line and can each be
assigned an individual device address.
The KNX / DALI Gateway
communicating with up to 64 DALI devices including
detection and transmission of DALI status and failure
information via KNX. DALI actuators can be switched and
dimmed either individually or in groups. If a DALI
actuator is assigned to one of the 16 groups it cannot be
controlled individually anymore. An individual name, a
group, pa-rameters and scenes (refer to the application
program description) are assigned to the individual DALI
electronic ballasts during commissioning with the ETS
(Engineering Tool Software).
The power supply unit integrated in the N 141/02
supplies the gateway electronics and generates the DALI
voltage. Additionally, it enables the operation of the
gateway and a direct switching of all lamps controlled
over its DALI interface even if the N 141/02 has not yet
been commissioned with
communication via the KNX bus has been interrupted.
For this purpose, the N 141/02 has a pushbutton located
bottom left on its front plate for switching-on the "Direct

mode" as well as for switching back to the "Bus mode".
When this pushbutton has been pressed for the first time
the yellow light emitting diode (LED) lights up
permanently to indicate direct mode. Then all lamps
controlled via DALI can be switched On or Off all
together via the relevant two pushbuttons on the front
plate of the gateway: pressing briefly the upper
pushbutton switches the channel On while pressing
briefly the lower push button switches the channel Off. A
red LED integrated in the upper push button is used to
indicate the On state of the lamps by a continuous light
and to indicate a DALI cable error by flashing.
If the direct mode button is pressed for a second time,
the yellow LED to indicate direct mode is extinguished
and the N 141/02 is switched to "Bus mode".
The KNX / DALI Gateway N 141/02 can be used to control
DALI actuators in emergency luminaires. Self-contained
emergency luminaires containing two DALI devices
(ballast and an inverter, each with a DALI interface) only
up to 32 self-contained emergency luminaires may be
connected to an N 141/02. The gateway automatically
detects if a self-contained emergency lu-minaire contains
two or only one DALI
emergency luminaires with two DALI interfaces and
"normal" luminaires with only one DALI interface may be
connected to the N 141/02, but the total number of 64
DALI devices may not be exceeded.
Self-test of the inverters of self-contained emergency
luminaires can be started and the test result reported via
the bus. The type of test (function test, short duration
test or long duration test) that has to be started or has
started can be commanded or queried. A test result will
be reported automatically at the end of a test or can be
queried.
All luminaires controlled by a N 141/02 can be dimmed
to the set "Dimming value on emergency" even when
they are not effected by any mains or DALI power failure.
By this all luminaires may be dimmed to the same
brightness level as all
luminaires.
During "Emergency Operation" all luminaires will not
respond to any on/off or dim commands and cannot be
commissioned.
