Protected control apparatus

A control apparatus for protected switching of a load encompasses at least two switch units in series with a load, to permit delivery of energy to a load when each switch unit is switched on and to block it when at least one of the switch units is shut off; an electronic control system for triggerin...

Beschreibung
Zusammenfassung:	A control apparatus for protected switching of a load encompasses at least two switch units in series with a load, to permit delivery of energy to a load when each switch unit is switched on and to block it when at least one of the switch units is shut off; an electronic control system for triggering each switch unit via a first switching path and second switching paths, and for monitoring its state; a delay element on the first switching path, such that each switch unit can be shut off both by way of a shutoff signal conveyed via the first switching path and by way of a shutoff signal conveyed via the second switching path; and in a state in which one of the switch units is shut off and the other is switched on, the electronic control system ascertains a malfunction of the first switching path if, after output of a shutoff signal on the first switching path, the other switch unit does not shut off within a predefined time window.
