Surge map screen - List view
Figure 44: Surge map screen - list view
The surge map can be shown in either Table (default) or List view as selected with the MAP VIEW
key.
Shown above is the List view. In this view, the Delta P/P, Pre-Rotation Vanes position and VSD
output frequency of each mapped point are listed. It is the same report that is generated when
the surge map is printed to a printer. Therefore, this view cannot be selected while a print is in
progress. If the SURGE MAP key is pressed on the ACC DETAILS Screen while a print is in progress,
the Map View is reset to Table if it is set to List.
The PAGE UP and PAGE DOWN keypad keys are used to scroll to the previous or next list of
parameters.
This screen is applicable to Variable Speed Drives (VSD) (with the Motor Communications Protocol
Setpoint set to Modbus; ACC Board is not present) and Medium Voltage Variable Speed Drives
(MVVSD).
Note: Requires a login access level of SERVICE.
