<p>The motor drive devices are remotely configurable to specific settings. The installation comprises a group of activating devices of which two (A1, A2) are shown. These are situated within a casing (C1, C2) and are used to operate roller blinds (PO1, PO2). The activating devices are powered by the mains via a common switch (S). The activating devices may be remotely controlled by a remote control transmitter (ET). Each comprises a variable gain receiver, processor, sound signal generator and a motor. The processor is capable of recording instructions acquired during a programming phase. Initially all the activators are identical, but by application of an electromagnetic field they can be programmed to the necessary settings, providing information such as the positions of the end of course movement for the motor.</p> |
