Figure 33: Current circuit and Fuse failure supervision functions
Three arc detection function stages ARCDSARC1...3 are included as an optional
function. The arc detection offers individual function blocks for three arc sensors
that can be connected to the merging unit. Each arc detection function monitors
the light information from an arc and delivers a signal, if an arc is detected.
The output signals from ARCDSARC1...3 are connected to the disturbance recorder
function block.
