The function of keys F1 to F4 is shown by a self-explanatory icon as appropriate for the particular
window. As shown in Figure 68 above, pressing F1 moves the cursor (resting in “OUTPUT”) from the
UPS Menu Window (2) to current record window (4) where it would first rest in “Input breaker closed’.
In a similar manner, pressing F2 would move the cursor from the Output data window to the Bypass
data window.
The summary menu tree is shown below. Refer to 8.2 - All Status and Event Messages Displayed
on the UPS Front Panel for a detailed description of each menu item.
