OVERVIEW
The surge map can be shown in either Table (default) or
List view as selected with the MAP VIEW key. Shown
above is the Table View.
In this view, a table is used to graphically represent the
surge map in the view window. The X-Axis is Delta
P/P, the Y-Axis is Pre-rotation Vanes position and each
drive frequency point in the surge map is represented
by an "X". To view the details of any mapped point,
position the green box (□) over the desired "X" using
the keypad arrow keys (▲▼◄►). The drive Output
Frequency, Pre-rotation Vanes Position and Delta P/P
of the selected point is displayed at the bottom of the
screen under Selected. The default position for the
green box is in the upper left corner of the view win-
dow. Once moved, it will remain at the last position.
The Present Operating conditions are indicated with an
"*" (as shown above) and are detailed at the bottom
of the screen under Present. If the present condition is
the same as a mapped point, the "*" will be replaced
by an "O".
Use the pan Left, Pan Right, Pan Up and Pan Down to
pan the screen view.
