7.3 Description of Fault Levels
The NICE3000
new
has almost 70 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 infor-
are handled according to the following table.
