  • Patent number: 9869727
    Abstract: A method for monitoring a power supply connected to a superordinate controller via a signal line, wherein the superordinate controller queries whether the power supply is operating faultlessly at variable intervals, where during faultless operation, a power-good signal is continuously transmitted by the power supply to the superordinate controller via the signal line and, if a fault occurs, an indicating signal is transmitted by the power supply to the superordinate controller via the signal line as a switching sequence of high and low signals such that each signal change of the switching sequence occurs only after a time period that is longer than an expected greatest query interval and each signal of the switching sequence that does not correspond to the power-good signal is shorter than a specified signal duration for indicating a total failure of the power supply, whereby the superordinate controller receives more information than previously.

  • Patent number: 8842403
    Abstract: An electrical system having at least one load that is protected by a protective device, where a tripping parameter, i.e., a tripping current of the protective device can be set. A control unit is provided to which a measured current value of the current consumed by the at least one load is supplied, where the control unit generates a limit value, which is provided to the protective device for setting a tripping parameter as a function of the characteristic curve of the measured current value. The control unit thus permits ongoing adjustment of the tripping parameters, i.e., the release current, according to the actual operating conditions.
