Motor control unit (REG) for controlling four sun protection or window drives (24 V drive). It allows for direct control of four 24 V sun protection drives via a sun protection central unit and a local switch. Additionally, multiple motor control units can be grouped together and operated collectively from a single switch. Furthermore, the logic behavior of the switch can be toggled between time logic and permanent logic. Time logic means that the MSE will switch to self-holding mode after approximately 2 seconds of switch activation. A shorter activation of the switch generates a reverse pulse (for slat products), while permanent logic causes the MSE to immediately switch to self-holding mode upon switch activation (for fabric products/roller shutters). The program also includes a slat opening function, which ensures that the slats, for example in blinds, do not twist or stick together. A brief activation at the lower end position ensures a uniform slat alignment. Through a locking input, the sun protection motor can be disabled as soon as, for example, a window is opened. Local grouping is done via DIP switches. Note: An external power supply for the 24 V motor is required.
