Change Over Box
138- -119
All above mentioned status messages and/or alarms can
be output out of each Distribution Unit and can be indi-
cated at external alarm devices/systems.
Only the "System Failure" of Distribution 1 switches the
relays of the Change Over Box.
If a "System Failure" occurs in the Distribution Unit 1, all
other status messages and/or alarms of the Distribution
Unit 1 are without interest.
If a "System Failure" occurs in the Distribution Unit 2, all
other status messages and/or alarms of the Distribution
Unit 2 are without interest.
The DV bus, which is also output from a Dis-
tribution Unit is not switched--over.
