Switch/dimming actuator N 525E, 8x DALI
5WG1 525-1EB01
Product and functional description
warning before switching off the lighting,
switching status, dimming value status, lamp failure,
DALI status (lamp failure, short circuit, failure of the
power supply),
- identical configuration for all 8 channels or individual
configuration per channel,
- 8-bit scene control with up to 16 scenes per channel,
- behaviour on failure and recovery of the EIB bus
voltage or mains voltage.
The dimming times, dimming limits and the switch
behaviour when dimming brighter/darker and setting
dimming values can be set. The application program can
be loaded from ETS2 V1.3 onwards.

Bus mode / direct mode
The switch/dimming actuator N 525E is a KNX EIB device
with 8 DALI outputs (= channels). A group of up to 8
DALI devices can be connected per channel.
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 EIB/DALIGateway GE 141 can be used for example to control up
to 64 DALI devices individually.
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.
Application program
The switch/dimming actuator N 525E requires the application program 25 A8 Dali switch/dimming actuator
980801. There is a distinction between bus mode and
direct mode. The following functions and objects can be
used per channel in bus mode:
- normal operation, night mode, 1-level or 2-level time
switch mode (e.g. for controlling colour lighting),
- switching, dimming, dimming value,

The N 525E has an integrated power supply unit for AC
230 V to supply the actuator electronics and to generate
the DALI bus voltage per channel, as in the DALI system
(in a similar way to EIB) the electronics of the DALI
devices is supplied via the DALI bus cable.
The power supply unit integrated in the N 525E enables
the actuator and the lamps connected to its channels to
be operated even if the N 525E has not yet been
commissioned with the ETS (Engineering Tool Software)
or if the communication via the EIB has been interrupted.
For this purpose, the N 525E has a push button located
bottom left on its front plate for switching on “Direct
mode” as well as for selecting a group of 4 channels.
When the button is pressed for the first time, the LED
lights up permanently to indicate direct mode. Channels
A to D can then be operated directly. If the direct mode
button is pressed for the second time, the LED flashes to
display direct mode. Channels E to H can then be
operated directly. If the direct mode button is pressed for
a third time, the LED to indicate direct mode is
extinguished and the N 525E is switched to “Bus mode”.
In “Direct mode”, a channel can be operated via the
relevant push buttons on the front plate of the actuator
as via bus push buttons: pressing the upper push button
briefly switches the channel on while a long push button
action is used for dimming brighter; pressing the lower
push button briefly switches the channel off while a long
push button action is used for dimming darker. The state
of channels A-D whether the output is switched on or off
as well as by 1 Hz flashing if an error (e.g. a lamp failure)
is present is indicated by LEDs integrated in the lower
push buttons while the state of channels E-H is indicated
via LEDs integrated in the upper push buttons.
It can be set via a parameter whether direct mode is
switched on permanently or for a limited time period.
The factory setting for the operating time of direct mode
is 15 minutes. Each push button action in direct mode
leads to the restart of the timer for the operating time in

direct mode for the set time period. Once the operating
time has elapsed without any further push button
actions, direct mode is switched off automatically and
bus mode is reactivated (provided that communication is
possible via the EIB). In bus mode, pressing the push
buttons on the front plate of the actuator to switch a
channel on or off has no effect.
When direct mode is switched on, any switching, value
and scene retrieval commands are stored temporarily
and carried out automatically once the device is switched
back to bus mode.
