Impulse group switch for central control, 1 + 1 normally open contact, not potential-free 10A/250V AC, for a 230V AC motor. Standby loss only 0.4 watts. For built-in installation. 45mm long, 45mm wide, 32mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. This impulse group switch implements the commands of the sensor relays or switches and buttons and switches a 230V motor for a shading element or a roller shutter. Control, supply and switching voltage 230V. A1, A7 and A8 must be controlled with the same potential as L. By using bistable relays, there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the short automatic synchronization before connecting the switched consumer to the mains. A universal button is used to control up, stop, down, stop in pulses via control input A1. A direction button for down can be connected via the RTD diode (polarity can be any). Another direction button for up is connected directly to A1. At the first down control pulse, the EGS61Z switches control input A1 to direction button. To switch control input A1 back to universal button, the supply voltage must be switched off briefly. Central up and central down are controlled with priority via the additional control inputs A7 and A8. With priority because these control inputs cannot be overridden by other control inputs as long as the central control contact is closed. The up or down switching position is activated with a control signal. A further control signal (700ms) continues the current action. The release delay is set with the RV rotary switch. If the impulse group switch is in the up or down position, the set delay time runs, at the end of which the device automatically switches to stop. The delay time must therefore be selected at least as long as the shading element or roller shutter needs to get from one end position to the other. The automatic reversing function is controlled with the WA rotary switch: If the setting is between 0.5 and 2 seconds, the automatic reversing function is switched on. In this case, the direction of rotation is only reversed after the delay time set with the upper rotary switch has elapsed, for example to pull up awnings or set blinds to a certain position. AUTO 1: No automatic reversing function and no comfort reversing function. A7, A8 and direction button: Press 1s: dynamic sequence (contact remains closed), stop with a new press. AUTO 2: Automatic reversing with 1s reversing time. In addition, the local comfort reversing function for blinds with a universal button on A1 is active: A double pulse causes slow rotation in the opposite direction,which is stopped with another impulse.
