Abstract (en)
[origin: EP2202411A2] The device (1) has a floating switch (8) designed as a network separation unit and switching the device based on delivery requirement of a liquid-transporting system (2). The switch detects activating and deactivating levels of a centrifugal pump (5). The switch shifts the device into an electrical idle position or into an electrical active position. A control transformer (9) electrically supplies the device. A charging part charges an energy storage (13) in the active position. The device and/or the transformer are separable from an electrical network (11) by a separation element (12). An independent claim is also included for a method for operating a controlling, regulating and/or monitoring device for a liquid-transporting system.
