The Compressor Geometry / Performance Status screen (Pg. 683) can be used to see the current and historical values of the rod loads and compression ratios, if the compressor geometry was configured. This page is accessed from the main annunciator setup by selecting “Inputs Status” followed by “Compressor Geometry / Performance”.
Compressor Geometry / Performance Status
The left side of the screen shows the rod load status, for each stage that has the piston size configured. The first pair of values is the current rod load in tension and compression. The second value is the average for each over the last day. The last two values are the peak loads over the last day, and the time.
The right side of the screen shows the current and average compression ratio for each stage with a discharge sensor enabled.
