rako RLED30CV4 4 Channel Light Dimmer Module
General
Rako RLED30CV4 modules are 4 channel dimmer units designed for use with
constant voltage LED devices (usually flexible tape lighting). They are
designed to accept a 12V or 24V DC supply from a power supply (normally the
power supply that would power the LED device if it were not to be dimmed) and
give a PWM (Pulse Width Modulation) output for smooth flicker free dimming.
RLED30CV4 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
30w/channel @ 12V
60w/channel @ 24V
Channel Addressing
When giving the RLED30CV4 a Rako channel address the next 3 channels are automatically assigned, sequentially from this point. For example, a module controlling an RGB fitting and addressed as channel 3 will control Red on channel 3, Green on channel 4 and Blue on channel 5.
Connections
Connect the RLED30CV4 module according to the wiring diagram overleaf. Note the unit is designed to be fed from a 12V or 24V DC power supply. The power supply should be of an adequate rating for the connected load. For example, if dimming 4m of LED tape light with a rating of 12V and 14.4W/m the power supply needs to be rated to give at least 57.6W. If more than 5m of tape lighting is to be connected it is generally recommended to parallel the connections at the RLED150CV1 module rather than connecting the start of the second strip to the end of the first. This avoids excessive voltage drop issues.
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). A Rako wireless wallpanel set as address
House 1 Room 4 will control and dim the module.
Should the module not respond as above then further investigation should be
made before proceeding further.
Set-Up and Addressing
RLED30CV4 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 (RA or RTC-Bridge etc.) or
download from our website:
www.rakocontrols.com.
Manual Addressing from Wallplate or Handheld Before any lighting scenes can be
programmed (see the wall-panel or hand-held manual) the RLED30CV4 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.
NOTE: The RLED30CV4 will use the channel number set as the start address
(usually red) and automatically assign the other colours subsequent channel
numbers.
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 address switches
The address numbers are set using the switches on the back of a Rako
transmitter. Binary coding is used and a diagrammatic explanation is given in
Fig 1. It is not however necessary to understand binary just set the House
switches to a different setting than the factory default and use a different
combination of Room switch settings for each room or area to be controlled
separately.
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 RLED30CV4 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.
Colour Cycling
As a default setting the RLED30CV4 module will not dim from Fade Up/Down
commands from a Rako transmitter but instead will start a colour cycle through
the colours programmed for Scenes 1–4 when it receives a Fade Up command. A
Fade Down command will stop the cycling.
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 RLED30CV4 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. Should for any reason you

Initial Addressing of a Rako Receiver Module
In the following procedure, both the controllers (wall panels and handheld remotes) and the receivers have an automatic time out after approximately 3 minutes when in programming or set-up mode. This feature avoids the possibility of either being left permanently in programming or set-up mode. This may cause confusion if either the controller or receiver times out before the procedure is complete. It is worth becoming familiar with the procedures before starting the addressing procedure. If at any time it is necessary to start again the controllers can be returned to normal mode by pressing the ‘Off button and the receivers by resetting the electrical supply.
If some receivers are already addressed to a the wall panel then they will
‘flash’ their connected lamps as their channel number is reached during
the stepping procedure, this allows the user to ‘identify’ which channel
numbers are already taken. To add a new receiver to an existing installation
step up through the channels until a channel number is reached where no
receiver flashes a load, this is then an available channel. If at any point
there is uncertainty as to whether a receiver actually flashed its load then
button 3 will flash the load but without stepping up or down a channel. If all
of the loads flash then this indicates that the current address is Channel 0.
Note: If it is not possible to see the connected lamps flashing when stepping through the channels it is possible to tell from the LEDs in the receivers which will momentarily go solid when their channel address is reached.
