• Acquisition of the power fault: this process is run indefinitely while no fault event
is detected.
• Priority management: the software determines whether the detected fault
requires the implementation of the priority policy
• Power Fault validation: this process is intended to validate the necessity for
a permutation with respect to the different delays and conditions intended to
avoid taking into account temporary fault conditions
• Permutation: implementation of the permutation of the relevant relay and
realization of the possible necessary fault management actions

This process consists in cyclically checking the TS “RF presence” from the
transmitters of the system, until a fault is detected. The next transmitter to be
checked can also be set externally from the process “Permutation” (see below).
6.2.2 Priority management
This function is aimed to take into account the status of the system with respect
to possible permutations that have been performed before.
If the reserve transmitter TXr is currently switched towards the dummy load (i.e.
it’s free to be used), no priority management has to be performed, and the result
of the function is just the validation of the fact that the permutation to be done
consists in putting TXr on air in the place of the current transmitter.
If the reserve transmitter is instead currently used to suInterlocktitute another
tranmitter, the priority of that transmitter has to be checked against the one of the
