RAKO BLIND AND CURTAIN CONTROLS
Over view
Module Options
Motorised Curtains and Blinds
can be controlled via relay pairs
contained in Rako's range of
contollers. Configured to suit
most motor types, whether that be
240V roller, Venetian or Roman
blinds, curtain tracks or low
voltage motors.
RACUB – The universal control module. Can be wired to suit all
options but may require more wiring than other modules.
Wired or Wireless
Rako modules and RAKs can be
controlled from either the Rako
wireless or CAT5 wired
communication.
RAK4R – 4 channel equivalent of the standard RACUB but in a
RAK format for centralised systems and the Rako CAT5 wired
network. Auxillary 240V terminals simplify wiring for 240V
motors.
RACUB-2L – Similar to the standard RACUB but with internal
wiring for simpler installation with 240V tubular motors.
RACUB-24DC – Similar to the standard RACUB but with internal
wiring for simpler installation with 24VDC tubular motors with 2
wire operation.
Features
All module options share the same control and programming
features. By default all units respond to both Scene commands
(Defaults are Scene 2=Up, Scene 4=Down, Scene 3=Stop)
and Raise/Lower commands.
Accurate control of the end-limits are set within the motors
themselves but the Rako modules have an adjustable Timeout
feature (default one minute) which opens the relays to avoid
having permanent power fed to the motors.
The wound coils in electric motors store a large amount of
energy in magnetic fields which can cause large currents
leading to arcing and relay damage. To prevent this Rako
modules have a 'Stop on Changeover' function. This allows
one relay to stop the motor before the second reverses the
motor when trying to perform an immediate reverse of direction.

RAKO CONTROLS
RAKO BLIND AND CURTAIN CONTROLS
Motor Type
240V Tubular Motors
To be successfully controlled by a
Rako system motors must be
designed to be controlled from
external relays feeding power to
one winding for Up and one
winding for Down. Motors that
have their own proprietry control
system embedded in the motor
cannot be controlled from Rako
curtain and blind modules*.
This is most apparent by the
motor having 3 wires coming
from the motor (L, N + E) rather
than the 4 wires (L, L, N + E)
required.
* Motors with embedded control
systems may be controllable if
they are available with an
interface for external control.
See the section ‘Bridge
Interfaces’ for details.

RAKO BLIND AND CURTAIN CONTROLS
Motor Type
24V DC Motors – 2 Wire
DC motors that have 2 wire
connections require a reversal of
polarity to change direction. 24V
DC power is supplied by the motor
manufacturer's power supply.
Volt Free Control.
Some motors require volt-free
contact closures which operate a
Motor Control Unit supplied with
the motor.
Cur tain Motors
Most curtain motors can be
controlled by a Rako RACUB or
RAK4R, the control requirements
can differ depending on the make
and type of motor in question.
Refer to Rako's technical support
department for more information.

RAKO CONTROLS
RAKO BLIND AND CURTAIN CONTROLS
Control
3 Button Control format.
Rako curtain and blind modules can
be operated by any of the
controllers and interfaces available
for the lighting control system, these
include Infra Red, Volt Free contact
closure, RS232, and IP. Controllers
include Rako wallpanels, hand held
remotes, and iPhone, iPad and
Android interfaces.
As the standard scene configuration for lighting is not a logical
control format for blinds and curtains, most Rako controllers have
options for more sensible layouts for such control. Typically
these controls have 3 buttons, for open/close and stop functions
and controllers with displays (Smart remotes and Apps) can be
configured for this style of operation. For areas where two
separate channels of controls are needed 6 button options are
available (e.g. where separate control for blinds and curtains
are required or where separate control for different aspects is
needed).
Plate Finishes
When a system is in the same room as a Rako lighting system
double gang control panels are available giving scene
controls for lighting on one side and curtain/blind controls on
the other.
Rako screw-fixing and screwless plate
kits are available in a selection of
finishes including:
Screw-fixing flat plates:
Brushed Stainless Steel
Mirrored Stainless Steel
Polished Brass
White Metal
Screwless flat plates:
Brushed Stainless Steel
Mirrored Stainless Steel
Polished Brass
Black Nickel
White Plastic

RAKO BLIND AND CURTAIN CONTROLS
Control from smart phones
Apps for iPhone/iPad and Android
phones allow configuration of
pages for blinds in each room,
along with channel control and
naming.
Bridges
Bridge Modules are the interfaces
between Rako systems and others.
Bridges with a time clock module
(TCM) fitted i.e. RTC or WTC
Bridges, can also trigger timed
events and replay normal activity in
a 'Holiday Mode'. Bridges also
have an ethernet link making them
the interface unit for Smart Phone
App interfacing.
The WRA232 Bridge has an RS232
data link. As some curtain and
blind motors with embedded control
systems have interface units
available which can accept custom
RS232 commands, the WRA232
Bridge can be used to send
commands to these units, allowing
override control of the motors from
the Rako System.

Multiple Channel control
Areas (rooms) that require multiple
channel controls (more than two)
can be contolled by 8 channel
control panels or handhelds. To
reduce the need for 8 sets of 3
button controls a 7 button wall
panel is available with functions to
select one of 8 channels (single
press for channels 1-4 and SHIFT
and press for channels 5-8) or All
channels open and close.
Control from standard lighting
control panels.
It is possible to split the function of
a standard 7 button keypad into
lighting and curtain/blind control
using advanced ignore functions
available from Rasoft. Using this
feature the 4 scene buttons plus Off
control the lighting and the
raise/lower buttons control the
blinds.
Remote Control From
Handhelds
Rako single gang wallpanel
arrangements are also available in
the RAH03, RAH06 and RAH07
handheld units and the RAHSmart
offers whole house control of both
lighting and curtains and blinds.
With a menu driven display
individual channels can be named
and controlled independently.
