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 SE-
LECTED. The default position for the green box is in
the upper left corner of the view window. 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”.
