Rako RDA800 User Manual

Rako RDA800 Installation, Programming and Operating Instructions

General

Rako RDA800 modules are dimmer units designed
for use with controllable fluorescent ballasts and
LED drivers, or any other suitable devices with
control inputs for 0-10V, DLI or DSI. RDA800
modules also have an internal relay that switches
the mains supply to the fitting.
RDA800 modules can be controlled by any Rako
device that transmits wireless RAKOM messages.

Before commencing installation of a Rako module please
read this instruction manual carefully. Rako Controls Ltd
accepts no responsibility for 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 module or remove the
terminal cover without first isolating the circuit at the
fuse/MCB board.The circuit supplying a Rako module
should always be protected by either a 5A fuse or 6A
MCB.

Mounting

Rako modules should be mounted in areas that
are adequately ventilated, dry and outside of any
enclosed metal casings that may interfere with the
wireless signal. Wherever possible the mounting
bracket should be used.
Modules should be mounted vertically, with the
terminals at the bottom, or horizontally with the
ventilation slots at the top.
Whilst Rako modules are designed to be
completely maintenance free the units should be
mounted in an accessible location should there be
a fault or re-addressing of the unit be necessary
(see 'Set-up and Addressing')

Loadings

Do not exceed the lesser of the two following
values: Relay output – Max 800VA

Control output – Max 25 devices.

Connections

Connect the RDA800 module according to the
wiring diagram overleaf. Note that the control end
of the module has three sets of header pins and
one connecting link. The connecting link is used to
select the appropriate control output for the load,
either 0-10V, DLI or DSI and is set on 0-10V as
default.
Do not use loop In/Out connections within the
module. A junction box should be used if required.
Ensure the cable clamp bar securely clamps the
cables and that the terminal cover is fitted before
switching the supply on.

Initial Checks

When power is initially connected to the module
the unit should switch the load ON. The load can
then be manually switched using the clear button
on top of the module. The factory set address for
both modules and transmitters is House 1 Room 4
(See Fig 1 for further information).

Set-Up and Addressing

RDA800 modules can be programmed manually
or by using RASOFT programming software. For
software programming refer to the appropriate
programming guide supplied as a PDF with the
programming interface.

Manual Addressing from Wallplate or Handheld

Before any lighting scenes can be programmed (see
the wall-panel or hand-held manual) the RDA800
module needs to be addressed.
To avoid interference between neighbouring
installations choose a House address other than the
factory default of House 1 and set this on the
transmitters using the House address switches. Keep
the House address the same throughout the project
(for master functions).
Choose a Room address for each separate room or
area to be controlled independently and set this on
the appropriate transmitters using the Room address
switches. Note: Any control panels set with the same
address will act as two or multi-way controls for the
same Room.
The module now needs to be sent its new House and
Room address from the appropriate keypad. For
rooms with multiple modules each module needs to
be also assigned a separate Channel number from
1-15 within each Room.
The House and Room addresses are set using the
switches on the back of a Rako transmitter (see Fig 1)
and the Channel addresses are selected by putting a
transmitter in programming mode and ‘stepping’
through the channel numbers (see Step 3 overleaf).
This number is then 'sent' (along with the House and
Room address) to a receiver (Step 5).

Notes on Addressing

A dimmer cannot be set to an address of House 0 (All
switches set to off).A dimmer will respond to, but not
receive an address of Room 0 (All switches set to off).
This Room 0 address is used for ‘Master House’
control. A dimmer cannot be set to channel 0. To
program a lighting scene see Wall panel or Hand held
manual.

Power-Up Mode

With the factory address setting of House 1 an
RDA800 will turn ON when power is applied.
When the House address is changed the
Power-Up mode becomes 'OFF' which is
generally preferred, for instance if there is a
power cut during a holiday.

Manual Operation

The clear button can be used as a manual On/Off
switch.

Multiple Control Panels

If the module is to be controlled by two wall or
hand- held transmitters it is only necessary to
address the module to one of these transmitters.
Set the other transmitters to the same House and
Room address and they will transmit exactly the
same message as the first transmitter and the
module will respond accordingly.

LED functions

The internal LED behind the clear button will
flicker when the module receives ANY Rako
wireless message and is a useful diagnostic
indicator. This function becomes inactive after 20
minutes to avoid nuisance light spill but can be
re-activated by pressing the clear button. If an
RDA800 module has already been addressed to
a wall-panel the internal LED will start to pulse as
soon as that transmitter (or any other transmitter
with the same address) is put into programming
mode. The module can still be re-addressed in
the normal way, for example when changing its
Channel address within the same Room.

Care and Maintenance

A Rako module contains no user serviceable parts.
