SECTION 5
ALARMS
The Governor controller reads many analog inputs and controls a host of digital IO in order to achieve the
system objectives and make sure the compressor is running optimally and efficiently. Tests are performed
constantly by the Governor controller in order to determine the state of the compressor system at any given
moment. Many of the tests are designed to check if certain parameters have been exceeded so that action
can be taken immediately to protect the machine, operators, and the facility.
The controller home page includes a banner near the bottom of the screen, which highlights the current
status of the machine and alerts the user of any alarms. Figure 168 below shows the home screen of
controller with the machine in the
enabled
state. This means the machine is ready to run and there are no
current system alarms; indicated by the green color. The colors of the triangles and banner border change
depending on the machine state and status. A shutdown or warning will appear as red or yellow on the
banner. An example of a shutdown alarm is shown in Figure 169 below.
