Instabus / DALI Gateway N 141 5WG1 141-1AB01

Product and functional description

The instabus / DALI gateway N 141 is a KNX EIB device
with one DALI output 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 output of the N 141.
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 bus line and can each
be assigned an individual device address.

The instabus / DALI-Gateway N 141 can be used to
control up to 64 DALI devices over the EIB. They can be
switched and dimmed either individually or in groups.
The N 141 also enables the detection and transmission of
DALI status and failure information. An individual name,
a group, scenes and parameters (refer to the application
program description) are allocated to the individual DALI
electronic ballasts during commissioning with the ETS
(Engineering Tool Software).

The power supply unit integrated in the N 141 supplies
the gateway electronics and generates the DALI bus
voltage. Additionally it enables the operation of the
gateway and a direct switching of all lamps controlled
over its DALI output even if the N 141 has not yet been
commissioned with the ETS or if the communication via
the EIB has been interrupted. For this purpose, the N 141
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 LED lights
up permanently to indicate direct mode. Then all lamps
controlled over the DALI bus can be together switched
On or Off via the relevant two pushbuttons on the front
plate of the gateway such as via a bus pushbutton:
pressing the upper pushbutton briefly switches the
channel On while pressing the lower push button briefly
switches the channel. A red LED integrated in the upper
push button is used to indicate the state of the lamps by
a continuous light and to indicate an error (e.g. a DALI
bus, ballast or lamp failure) 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 is switched to “Bus mode”.
Note

: If individual communication with each individual
DALI device is not required and you wish for example to
simply connect a group of dimmable fluorescent lamps in
parallel and control them in the same way as you would
previously have connected and controlled dimmable
electronic control gear (ECG) with a 1...10 V interface,
this is also possible with the switch/dimming actuator N
525E. Status and error signals are also detected by the N
525E and transmitted, whereby these signals are
assigned to the respective group and not to an individual
DALI device.
