POWER + control screen

3.4
The POWER + control screen is illustrated below. It is part of the control panel described on page
11.
How to read and understand the POWER + control screen is described in detail in Chapter control
screen is described in Chapter 8 beginning on page 37.
The control screen provides menus and displays all aspects of the POWER + systems input,
output and static switch as well as operational details.Figure 6: Default screen display
The figure below shows the POWER + 3-phase display.

This is how the control screen appears while the UPS is running normally.
3.4.1 Load-level bar graph
The load-level bar graph on the default screen display illustrates the approximate load on each
output phase of the UPS, as a percent of the maximum available output for each phase.
The load on each phase is represented by a series of from 1 to 10 dots. Each dot represents
about 10 % of the maximum available output per phase.
The dots can be either filled in (black) or clear (white). The number of black dots represent kW,
the number of black and white dots together represents kVA.
For example, in Figure 6 above, the load on Line 2 is 30 % (3 black dots) of the maximum in
terms of kW, and 40 % (3 black dots plus 1 white dot) of the maximum in terms of kVA.
To compute the approximate value in kW or kVA of each dot:
1. Compute the maximum load per phase =
2. Dividing the maximum load per phase by 10 gives you the value of 1 dot.
Example: Assume a system with 10 modules, 2 of which are redundant.
10 kva / 3 x (10-2) = 3.33 x 8 = maximum load per phase = 26.67 kVA. 26.67 / 10 = 2.67 kVA, the
approximate value of each dot.
