Ridder LogicLink300 • • • • Integration of drive unit and control unit Ready-made drive units – easy to install Material and labour cost savings thanks to fewer cables Optimum control and safety drive to innovate Ridder developed the Ridder LogicLink300 (RLL300) to provide the RW motor gearboxes with more intelligence and added value. The RLL300 is a complete drive unit with integrated mechanical and control components that operate together seamlessly. This offers new ways of optimizing climate control that were previously not possible. Reversing and protection components have been fitted in the RLL300 housing mounted to the motor gearbox. This means far fewer cables are required between the motor gearboxes and the central control cabinet, resulting in substantial cost savings in labour and materials. Two series of integratable control units are available for the Ridder RW motor gearboxes: the RLL300 and Ridder LogicLink600 (RLL600). Both are intelligent control units, but the RLL600 provides more extensive functionality than the RLL300. RLL300 The RLL300 control unit is a ready-made, easy-to-use solution for the installation and control of RW motor gearboxes in both rotational directions. The RLL300 control unit achieves this with a potted control board with solid state relays. This control unit is mounted directly onto a motor gearbox, so the drive unit and control unit are integrated. The RLL300 control unit is supplied as a stand-alone controller: the Ridder LogicLink320. This control unit can, for example, open or close individual vents and screens. The unit can be operated with manual controls or with a 24V AC/DC control signal from a climate computer. The stand-alone RLL300 unit is suitable for various supply voltages and mains frequencies and is connected to a power supply cable (1- or 3-phase) and a control signal from the manual control unit or climate computer. Benefits of the new RLL300 • The RLL300 is easy to use and connect, and requires minimal maintenance. • The system can be operated with a simple manual control unit. Connection to a climate computer is not necessarily required. • The unit provides optimum control and protection. • Fewer cables are required because the control unit is mounted on the drive unit. • The RLL300 can relay an error signal to a climate computer. • The control unit is potted, making it resistant to moisture, dirt and vibrations. • The unit is suitable for various supply voltages and mains frequencies, making it ideal for application in other countries and export purposes. • The RLL300 includes intelligent safety features and can identify phases. • The Ridder Positioning Unit (RPU) is easy to connect to the RLL300 power supply, so no additional no additional cables are required for the RPU. • The RLL300 is in the process for UL/CSA certification. GB04 v1.0 Safety and the RLL300 The RLL300 includes features to ensure maximum protection of the driven system and drive unit should an emergency situation occur. The RLL300 is equipped with rotating field detection for 3-phase supply voltages. The LogicLink detects when a phase switch occurs and makes the necessary control adjustments, such as operating the RW motor gearbox in the correct rotational direction. Phase detection ensures that no unwanted behaviour occurs should a supply voltage phase fail. The RLL300 no longer controls the motor gearbox in this situation. The RLL300 protects the electric motor of the RW motor gearbox against overloads. To do so, the electric motor must be equipped with a PTC (a thermistor whose Ohms resistance increases as the temperature rises). The RLL300 control unit is also capable of operating a safety switch. If the LogicLink300 detects an emergency situation, it is relayed by the control unit. www.ridder.com
