LogicLink RLL400 control

The Ridder LogicLink400 control unit is an intelligent control unit for controlling a Ridder RW motor gearbox. The LogicLink400 control unit is integrated with a RW45, RW240/400/600, RW800, RW1000/1400, RW1200/1600S or RW2000 motor gearbox. The LogicLink400 is suitable for various supply voltages and mains frequencies, and for both 3-phase and 1-phase currents.

The LogicLink400 control unit has a ‘solid state’ control circuit board with a microprocessor. This control circuit board has a connector for the supply voltage, a connector for an external control signal (24 V AC/DC), a connector for the manual controls and an NC fault contact connector. The power supply for the electric motor, the PTC thermistor in the electric motor and the RSU limit-switch system are also connected to the control circuit board of the LogicLink400.

In combination with a Ridder RW motor gearbox, the LogicLink400 control unit relays control commands from the climate computer or manual controls and monitors whether these are implemented without malfunctions. The LogicLink400 also protects the RW motor gearbox against overloading through constant measurement of the PTC thermistor. The LogicLink400 includes rotational field detection and phase detection of the supply voltage. The 24 V AC/DC controls input is protected against control in two directions and quick changes of direction. The LogicLink400 control unit has an NC fault contact and alarm LEDs for feedback of fault situations.

The LogicLink400 control unit is fitted with extensive and easily accessible plug connections and clamping strips. The LogicLink400 comes standard with cable glands for feeding out cabling. The protective classification of the LogicLink400 casing is IP54.
