Abstract
System for evaluating the operational state of the signaling light with the light source (S) is supplied via a supervision circuit block (DNZ) for controlling lighting of the signal lantern and via a reducing signal transformer from an alternating current voltage source, has a safety modification block (BBM) for modification of a feeding signal with a coupling to the supervision circuit block (DNZ) for recognition of light interruption and execution of a reaction in a superior interlocking safety device, wherein the safe modification block (BBM) is connected between the reducing signal transformer and the light source (S). Said safety modification block (BBM) is connected to the output of a safe supervision block (BBD) for the detection of the light interruption of the light source (S), which safe supervision block (BBD) has an optical coupling to the light source (S). A second version of a circuit arrangement for functional state evaluation of a signal lantern, provided with a light source (S) and supplied via a supervision circuit block (DNZ) for controlling lighting of the signal lantern from a direct current voltage source, is characterized in that the safe modification block (BBM) intended for modifying a feeding signal with a coupling to the supervision circuit block (DNZ) for recognition of light interruption and execution of a reaction in a superior interlocking safety device, is connected between the supervision circuit block (DNZ) for controlling lighting of the signal lantern and the light source (S). Said safe modification block (BBM) is connected the output of the safe supervision block (BBD) for the detection of the light source (S) light interruption, wherein said safe supervision block (BBD) has an optical coupling to the light source (S).
