Abstract

For the purpose of initialising the channels (2, 3) after a disconnection process, a two-channel emergency shutdown device (1) is provided with a first initialisation circuit (4) which is activated with the aid of a manual key (21), which can be operated arbitrarily. In order that the emergency shutdown device (1) is brought to the switched-on state automatically, even after the supply voltage has been restored, there is a second initialisation circuit (5), which operates as a function of the restoration of the voltage and otherwise has no effect. <IMAGE>
