The device has two reset inputs, Y2 (without reset monitoring) and Y3 (with reset monitor ing). The two relays, K1 and K2, are activated automatically (bridge Y1-Y2) or by operating the reset button (on Y1-Y3). They switch to self-maintaining via their own contacts, if there is an electrical connection (emergency stop button, position switch) between terminal A1 and the supply voltage. After this switch-on phase the enabling current paths are closed and the signalling current path is open. If the electrical connections between terminal A1 and the supply voltage are interrupted, the enabling current paths open and the signalling current path closes. The excitation condition (self-maintaining) of the two channels is indicated by a green LED K1, K2. A second green LED indicates the presence of supply voltage.
