A monitoring module for protective-conductor monitoring has a monitoring circuit, by way of which it is checked whether a protective conductor is properly connected. If a protective-conductor interruption is detected, the monitoring circuit identifies this as a first fault case and outputs a first fault signal. The monitoring circuit is designed additionally to store the first fault case and outputs a second fault signal in the event of an only temporary protective-conductor interruption that is no longer present. By this measure, improved protection of persons is achieved, even in the event of, for example, intermittent contacts, etc. |
