Product and functional description
The Venetian blind switch N 523/02 is a DIN rail mounted
device in N-system dimensions with a width of 4 module
units. Only one AC 230V drive (motor) with electro-
mechanical limit switches or with integrated electronics
for disconnection at the limit positions can be connected
to a channel of the 4-fold Venetian blind switch
N 523/02. The parallel operation of several drives on one
channel requires the intermediate switching of a special
relay. Apart from moving the sun/anti-glare protection
into one of the two limit positions, the Venetian blind
can also be stopped and the slats can be adjusted step-
wise.
The power supply of the Venetian blind switch elec-
tronics is carried out via an integrated power supply unit,
which is fed via the mains connection L1 for channels A
and B. The mains connection of channels C and D is car-
ried out via the connection L2. This enables two channels
to be connected to different external conductors. If this is
not required, one of the terminals L1 must be linked to
one of the terminals L2 via a wiring jumper.
For direct operation (also in the event of communi-
cations failure or if EIB communication has not yet been
put into operation), four pairs of push buttons are avail-
able on the top of the device. For direct operation, both
AC 230 V and bus voltage must be applied at the actua-
tor. Moreover, the actuator must be switched to direct
operation via the appropriate push button with an LED.
In direct operation mode, an output remains switched on
while the associated push button is pressed. As the direct
operation is completely isolated from the bus communi-
cation, any active safety alarm or protection mode (for
blocking the raising or lowering of the sun/anti-glare pro-
tection) is not taken into account.
Application program
The sunblind switch N 523/02 only works together with
the application program 25 A4 Sunblind switch 980103.
Due to its two 1 bit command objects which are always
available per channel, the program enables the move-
ment of a Venetian blind into the upper or lower limit
position, stopping the movement of the Venetian blind
as well as the stepwise adjustment of the slats. The ad-
justable period for gradually opening the slats or gradu-
ally raising the sunblind again once it has reached the
lower limit position only becomes into effect if the sun-
blind has been lowered from the upper limit position
without any interruptions.
When commissioning the sunblind switch the following
objects can be added to all the channels :
-one object “Move-up blockade On/Off“
(required e.g. for cleaning)
-one object “Move-down blockade On/Off”
(required e.g. for interior sun protection and when
the window is open)
-two 1 bit objects for saving/restoring two Venetian
blind/slat positions
-two 8 bit status objects (Venetian blind and slat posi-
tion as percentage values).
In connection with a weather station, in the event of a
wind or rain alarm it is ensured via an alarm object that
the sun/anti-glare protection is for example raised auto-
matically and that the lowering of it via the EIB is pre-
vented when there is an alarm.
It can further be selected whether the parameterisation
is adopted for all the channels or whether each channel
should be configured individually.

General description
The DIN rail mounted device with N-system dimensions (4
module units) can be inserted in N-system distribution
boards, either surface- or flush-mounted, and wherever
EN 50022-35 x 7.5 DIN rails are available. The contact
with the bus line is carried out via the bus terminals or
via the contact system to the data rail.
Assembling the DIN rail mounted device (Figure 2)
-Place the device (B1) on the DIN rail (B2) and
-rotate the device downwards until the slide switch au-
dibly clicks into position.
Dismantling the DIN rail mounted device (Figure 2)
-Remove all the connected cables,
-press the slide switch (C3) down with a screwdriver
and
-remove the device (C1) from the DIN rail (C2) with a
swivel action.

Removing the bus terminal (Figure 3)
-The bus terminal is located on the top of the Venetian
blind switch N 523/02 (D1)
-The bus terminal (D2) consists of two sections (D2.1,
D2.2), each with four terminal contacts. Care should
be taken not to damage the two test sockets (D2.3) ei-
ther by accidentally connecting them to the bus con-
ductor or with the screwdriver when attempting to
remove the bus terminal.
-Carefully insert the screwdriver in the wire entry slot
underneath the bus terminal (D2) and pull the bus ter-
minal forwards out of the Venetian blind switch
N 523/02 (D1).
Note
When removing the bus terminal, there is a danger of
short circuits.
Plugging in the bus terminal (Figure 3)
-Place the bus terminal (D2) in the guide slot and
-press downwards until it reaches the stop.
Connecting the bus cable (Figure 3)
-The bus terminal (D2) is suitable for single-core con-
ductors with 0.6 ... 0.8 mm Ø.
-Strip approx. 5 mm of insulation from the conductor
(D2.4) and then plug in the terminal (D2) (red = +,
black = -).
Disconnecting the bus cable (Figure 3)
-Remove the bus terminal (D2) and the conductor
(D2.4) from the bus cable by rotating them simultane-
ously backwards and forwards.

Figure 3: Connecting and removing the cable
Connecting the mains voltage and Venetian blind drives
-The connections are carried out with plug-in terminals.
-Strip approx. 9-10 mm of insulation from the conduc-
tor and slide into the respective terminal.
-Outputs A and B are supplied via terminal L1 while
outputs C and D are supplied via terminal L2. This en-
ables two outputs to be connected to different exter-
nal conductors. If all the actuator outputs should be
connected to the same external conductor, a terminal
L1 must be linked to a terminal L2 via a wiring jumper.
Cross-sections:
•The following conductor cross-sections are permitted:
-2 x 0.5... 2.5mm² single-core or 2 x 0.5... 1.5mm²
finely stranded with connector sleeve
•Each of the mains connections L1 and L2 must be
fused with a miniature circuit breaker of characteristic
B or C with a max. nominal current of 10 A.
Mounting the insulating cap
If the device should be mounted on a DIN rail without an
data rail, the contact system must be covered with the
supplied insulating cap.
Removing the locating clamp: (Figure 4)
-The locating clamp (D3) encloses the contact system
(D2) on the rear of the Venetian blind switch (D1).
-Insert the screwdriver between the DIN rail mounted
device (D1) and the locating clamp (D3) and remove
the clamp.
Clipping on the insulation cap: (Figure 4)
Place the insulating cap (D4) on the contact system and
press so that it snaps in place.
