Software Operation Overview Diagram
The following figure is a diagram of the five possible
software states. This diagram can be thought of as a
state chart, with the arrows and arrow text, depicting
the transitions between states:
• The text in the circles is the internal software
designations for each state.
• The first line of text in the circles is the visible top
level operating modes that can be displayed in
Tracer® AdaptiView™.
• The shading of each software state circle
corresponds to the shading on the time lines that
show the chiller’s state.
There are five generic states that the software can be
in:
• Power Up
• Stopped
• Starting
• Running
• Stopping
