The blackout of a Distribution Unit is not displayed at the Op-
erator Units.
Therefore it is constraining necessary to connect the error
message "System Failure" from each Distribution Unit to an
external alarm device.
The error message "System Failure" is generated if a Dis-
tribution Unit is dropped out.
