This chapter describes the procedure performed
when changing the operation of the function block
of the FVX110 in process.

Out_Of_Service, the function block pauses and a
block alarm is issued.
9.2 Generation of Alarm
9.2.1 Indication of Alarm
The self-diagnostics function of the FVX110 uses
the display to notify the user of the following three
faults.
