% Load With Redundancy Status Screen Battery Status Screen

Fig 7-7 Percent Load With Redundancy Status Screen

%Load Allowing For Redundancy - displays the percent of the non-redundant Power Array capacity that is required by the load. The non-redundant Power Array capacity is de- fined by the number of user defined non-redundant power modules installed multiplied by 4kVA, and it is limited by the kVA rating of the frame. See table 7-1. After the load with redundancy status screen has been reviewed, press the Enter key. The frequency status screen appears.

Note: The redundancy level for this measurement is user de- fined and will be assigned in step 6 of this procedure. Either zero, one, or two of the power modules will be designated as “redundant.” The remaining power modules are then defined as “non-redundant.”

Table 7-1 Non-Redundant Power Array Capacities

Fig 7-9 Battery Status Screen

Battery Status Screen - displays battery voltage, the percent- age of available battery capacity, number of battery modules that are installed, number of battery modules that are “bad,” and the predicted run time. Use this screen to check the sta- tus of the battery modules. After the battery status screen has been reviewed, press the Enter key. The power status screen appears.

Note: If a battery module is diagnosed as “bad,” see Chapter 8.

Power Status Screen - the reported Power Array capacity is dependent upon the number of power modules installed and the size of the frame. Use table 7-2 to confirm that the PowerView is reporting the correct information.
