The control panel also receives data from the DEUs on the
DFDAU bus. This function is used to download fault history from
the DEUs
A function discrete from the data loader is switched through the
data loader control panel to the DEUs. This ground discrete is
the load enable signal to the DEUs.
Airplane Condition Monitoring System
The DEUs send EEC data on the ENGINE EEC buses. The DEUs
send all the labels received from the four EEC input buses to the
FDAU. EEC channel A data for both engines goes from DEU 1
and EEC channel B data for both engines goes from DEU 2. This
data is used by the airplane condition monitoring system.
