Performance curves

The compressor performance curves are drawn on the basis of the information configured for a curve set, and on the basis of the curve set currently associated with the specified compressor.

The color, label, and data points for each of the following are configured as described in Curve set configuration:

• Surge Line

• Surge Control Line

• Speed Curves

• Efficiency Curves

The performance curves have labels for the efficiency and speed curves as well as value indicators for each curve line.

If the compressor curve set associated with a compressor is reassigned or modified, easy eXtended Operator Station (ezXOS) re-translates the curve data and the curve set on the compressor performance plot display is immediately redrawn.
