1 What is the RACUB? A RACUB is a dual relay switching module designed for motor control, it is suitable for controlling curtains, blinds and 3rd party volt-free contacts.

The RACUB can be programmed for basic functionality using an RCM switch, although it is highly recommended to use Rasoft Pro and a compatible programming device such as the RAMPI or RK-HUB. 2 Loadings Load Type Load Voltage Max Load

230VAC 2A

AC Motor

12VDC 2A

DC Motor 3 Installation

Ensure the limits are set on the connected motors before energising the RACUB. Installation should only be carried out by a competent electrician.

RACUB 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.

Modules should be mounted vertically, with the terminals at the bottom, or horizontally.

While the modules are designed to be maintenance-free, they should be mounted in an accessible location should investigation or re-addressing of the units be necessary.

Ensure that the cable clamp is fitted tightly to secure the cables.

For more information on wiring configurations, refer to the Dual Relay Wiring Overview.

NB Always check with the motor manufacturer for

compatibility before MAINS MOTOR | DC MOTOR | DRY CONTACT installing. Ensure that both covers and 4 clamps are replaced on both ends of the RACUB.

4 Initial Checks

A Wireless keypad can be used to test the relays on the default programming of House 1 Room 4.

The internal LED behind the ‘Magnet’ side of the module will flicker when the module receives any Rako Wireless message and is a useful diagnostic indicator. 5 Programming the RACUB

Once the RACUB has powered up, it can be tested working with a House 1 Room 4 Keypad using the Raise and Lower buttons, then the device is ready to be programmed. For instructions on how to program the RACUB, see section “3.3 - Modules with magnet setup” in the Wireless Module Setup Guide. RACUB Instruction Manual | Page 4 Manual Version 2.0.1

1. Relay Timeouts Enabled by default. Defines the time (in seconds) before the relays disengage after activation. 2. Test Sends test commands to the relays. Before testing, ensure the motor wiring complies with the manufacturer’s instructions and that any required limits are set on the motor. 3. Fade Button Options No Action – Fade commands will have no effect on the motor. Enable Momentary Action – Relays engage only while the fade button is held. The relays will disengage when released. An optional setting allows the relay to latch after a specified time. Enable Latching Action – Relays engage when the button is pressed and disengage after the configured timeout (default: 127.5 seconds). 4. Fade Up / Fade Down Button Assigns which relay is controlled by the Fade Up and Fade Down commands. 5. Changeover Defines the delay between switching relays. It is recommended to leave this at the default setting, as reducing the delay may cause damage to the motor. 6. Defaults Reset for Smartphone – Restores default relay timeouts with latching action enabled. Reset for 1 Second Dry Contact – Sets relay timeouts to 1 second with momentary action. Commonly used with interfaces requiring dry contact pulses to control the motor.
