This section describes operation and use of the alphanu-
meric display in detail.
The alphanumeric display interacts with the user via the top
half of the hidden panel (Figure 2-4). Figure 2-18 shows
the general organization of the alphanumeric display.
During normal operation, when there are no alarm conditions present and the load is supplied
by the UPS inverter output, the display will present the general status message:
LOAD IS PROTECTED
UPS IS ON LINE
When there are alarm conditions, the display will present a general alarm message, and the
user can use the “alarm” pushbutton (!) to determine the exact cause of the alarm condition
(see Section 2.3.2, Alarms).
The following sections present detailed operating instructions for the alphanumeric display.
