ABSTRACT:
The invention relates to a safety system having electrical consumers (18a, 18b) which are supplied with electrical energy in normal operation from an electrical energy source (2, 4, 6). The safety system includes an electrical energy store (14a, 14b) which supplies the electrical consumers (18a, 18b) with electrical energy when the instantaneous operating voltage at the energy source (2, 4, 6) drops below a limit value. The rated voltage of the energy store (14a, 14b) is less than the rated voltage of the electrical energy source (2, 4, 6) and the electrical energy store (14a, 14b) is connected to the electrical energy source (2, 4, 6) via a switchover element (16a, 16b) which assumes the function of a diode. The switchover element (16a, 16b) ensures that a switchover from normal operation to an emergency operation takes place automatically and that, during normal operation, the electrical energy store (14a, 14b) is not charged unintentionally by the electrical energy source (6).
