Abstract
A method for detecting faults, in particular transient faults which cannot be verified which occur in an electrical unit, such as a switching device, by means of a fault counter which, when a fault occurs, counts by a specific first counting value in a first counting direction and which, at specific times, in each case counts by a second counting value in an opposite second counting direction in the situation where no faults have occurred within the relevant time interval. A precautionary alarm signal is triggered on reaching a first counting threshold value in the first counting direction. A second alarm signal, in conjunction with the monitored unit being switched off, is produced on reaching or exceeding a second counting threshold value, which is higher than the first counting threshold value.
