Installation, Programming and Operating Instructions.

General

Rako 0907-S curtain and blind control units allow control of most blind
and curtain motors. The 0907-S has two change over relay outputs. The
0907-S requires a 24V DC supply. The units are controlled using either
the Rako single or 8 channel switches and/or transmitters. The wall­switches and hand-held transmitters communicate with the units using
coded FM radio control signals.

Permissible loadings.
The maximum permissible load current is 2A per unit. The units should
not be used to switch loads other than 24v DC motors.
If in doubt contact Rako by telephoning 01634 226666.

Installation

Before commencing installation of a Rako unit first read this instruction
manual carefully.

Rako Ltd accepts no responsibility for any damage or injury caused by
incorrect installation of a Rako product.

Installation should only be carried out by a competent

electrician.

Never attempt to connect a Rako unit or remove the terminal covers
without first isolating the supply.

Rako units should be mounted in areas that are adequately ventilated, dry
and outside of any enclosed metal casings. Wherever possible the units
should be securely fixed using the mounting holes provided. The
mounting holes are blanked off when supplied but are designed so that a
woodscrew will easily cut through without the need for drilling.

Whilst the Rako units are designed to be completely maintenance free
they should be mounted in a position where access can be gained should
there be a fault or re-addressing of the unit be necessary (see ‘Set-up
and Addressing’).

Fig 2.

Termination Area

To ensure that the cable clamping operates satisfactorily the cabling
supplying both the unit and the blind/ track should be a minimum of

0.75mm2 with double safety insulation and the wires should be stripped to
ensure that the cable bar within the terminal cover clamps firmly on
insulation.

To install a Rako RACUB-24DC unit isolate the supply then remove the
terminal covers (see Fig.1) giving access to the supply/load terminals.
The necessary connections are indicated on the label on the unit housing.

4 Motor 2 -

Once the supply and load cables are connected ensure that the terminal
covers are replaced and securely fastened, clamping the cable correctly
before powering the unit.
Rako units are not designed for loop in/loop out connections. Should it
be necessary to loop the supply on to further fittings then a junction box
should be connected in circuit to facilitate this.

With the supply and load connected and prior to switching on the supply
ensure that the terminal covers are fitted and that they are securely
clamping the cables. It is important to ensure that the protective inserts
(see Fig.1) are fitted and located securely, both in the terminal cover and
over the supply and load cables. The protective inserts provide important
protection against the risk of electric shock from conductive objects
forced down the side of the cables.

Set-up and Addressing

To avoid interference between adjacent rooms of a house and
neighbouring houses as well as allowing individual control of separate
curtains/blinds within a room Rako radio units employ a structured
addressing system.

Rako radio units use a structure based on house, room and channel
addresses. Using the two banks of DIL switches on the back of a wall
mounted switch or hand held transmitter (see Fig.3) a House address can
be selected from one of up to 255 possible addresses and a Room address
from one of up to 255 possible addresses.

Note

House 0 is not a valid address and Room 0 is a special address which
gives overall control for a whole house. Room 0 should not be selected
as a Room address without careful thought to the application.

Setting an address is the way in which interference between other Radio
Controlled Rako units, either with other rooms within your house or
neighbouring houses is avoided. It should be remembered that a Rako
transmitter may have a range of over 100m.

Rako controllers come set with a default address of House 1, Room 4,
Channel 1 and whilst the unit will function with this address it is strongly
advised that a specific and logical address for both House and Room be
selected
Units can be given channel addresses from 1-8 allowing control from the
8 channel wall mounted switch or transmitters

Some advanced grouping arrangements are possible allowing banks of
units to be controlled as groups within a room. Systems with advanced
programming need to factory set. For more details contact Rako.

Setting an Address

Each Rako transmitter has two, 8 way banks of switches for setting its
address. The two sets of switches allow the user to choose from 255
house addresses and 255 room addresses. To set the address, remove the
rear cover (refer to controller manual for details), whereupon the banks of
switches will be now become visible. To set an address, use a small
terminal screwdriver or similar device and carefully move some of the

switches into the ‘ON’ position. Addressing uses binary encoding and the

value of the switches is shown below.

Fig 3.

Addressing Switches

Once the addresses have been set it is strongly recommended to keep a
note of the settings and to keep these in safe place. Whilst it is easy to
set the addresses, those of the receiver units are normally only set once.
To do so requires access to the units and once set these may be installed
in inaccessible positions. If, therefore the wall-switch address get
changed for any reason and the original settings cannot be remembered
then access to the receiver units will be needed for reconfiguration.

Setting receiver addresses.

Once a House and Room number have been selected on a wall switch or
transmitter these need to be transmitted to each receiving module along
with a valid channel number. This is done by one of two methods using
a Rako wall-switch/transmitter. The method varies depending on
whether an 8 or single channel version is being used.

Note

When addressing from a single channel version only channel one can be
set. If single channel controller is being used in the same room as 8
channel version then it is strongly advised to program using the 8 channel
controller.

To send an address to a receiver unit, the unit needs to be put into
receive mode. To do this hold the magnet provided against the side
casing in the position indicated by the label and as shown below.

Fig 4. Set-up Magnet Positioning

Once the magnet is in the correct position an internal LED will illuminate.
If the magnet is held in position for approximately 5 seconds the LED will
start to flash, this flashing indicates that the unit is ready to receive an
address from a transmitter.

Sending address from an 8 channel transmitter/wall switch

From either a Rako channel wall switch or transmitter (both are
functionally identical) press the appropriate channel button with the
receiving unit set with the LED flashing. To send Channel addresses 1-4,
select the channel by pressing the appropriate channel button and then
send the command by pressing the Open button. This action
automatically sends the House, Room and selected Channel address. To
select addresses 5-8 the ‘All’ button needs to be pressed (to shift the pad
into 5-8 mode) and then send by pressing the Open button. As soon as
the receiver gets a valid address it automatically drops out of set-up
mode.

Note

If a receiving unit, in set-up mode, does not receive a valid address within
3 minutes the receiver will automatically drop out of set-up mode.

Sending address from a single channel transmitter

From either a Rako single channel wall switch or transmitter (both are
functionally identical) press and hold both buttons for 5 seconds. After 5
seconds the unit will automatically send a channel 1 address. The red
LED on the transmitter will flash to confirm that this has been sent. As
soon as the receiver gets a valid address it automatically drops out of set­up mode.
