Motor control unit (MSE) for controlling up to two 230 V AC sun protection drives. It allows for direct control of up to two 230 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. Grouping is achieved not by rewiring, but by toggling the corresponding DIP switch. The logic behavior of the switch is a time logic with reversing automation. The time logic ensures that the MSE enters a self-holding state after approximately 2 seconds of switch activation. A shorter activation of the switch generates a reversing impulse (for slat products). The control voltage of 24 V DC is provided by an integrated power supply, which is necessary for controlling the MSE via the switch or the sun protection central unit. The slats automatically reverse immediately after reaching the lower end position, with end position detection through current monitoring. The angle of the slats can be adjusted via DIP switches. It includes a control program for WAREMA Venetian blinds with working position (switch spring and impulse reversal). This is the REG variant.
