9.1 Description of Fault Levels
The NICE3000
new
has almost 60 pieces of alarm information and protective functions. It
monitors various input signals, running conditions and feedback signals. If a fault occurs, the
system implements the relevant protective function and displays the fault code.
The controller is a complicated electronic control system and the displayed fault information
is graded into five levels according to the severity. The faults of different levels are handled
according to the following table.
