5. FRONT PANEL KEYPAD & LCD OPERATION
5.1 SYSTEM SOFTWARE COMMANDS (via the front panel)
The keypad on the front panel of the UPS can be used by the operator to select the information
displayed on the LCD display, as well as to input various set-up parameters.
A. HELP key
- Pressing this key will result in a "pop-up" display giving a short description of the
functions of the buttons on this keypad. Pressing the ESCAPE key while in this display, will return you
back to the display that you were on when you pressed the
HELP key.
B. ALARM RESET key
- Press this key to silence the
audible alarm indicating either the battery is discharging or
an alarm exists. If an alarm exists, the audible alarm will
be accompanied by the LCD display indicating what the
problem is. Pressing the ALARM RESET key will silence
the audible alarm and the LCD display will revert back to
its mode of operation prior to the alarm. There are four
categories of alarms: Shutdown, Overload, Diagnostic,
and Warning. It is possible for more than one of these
categories to exist at a time. In such a case, pressing the
ALARM RESET will display the second category of
alarms, which will require a second pressing of the
ALARM RESET button to silence the audible alarm and
clear the alarm display. Note that pressing the ALARM
RESET will not clear the problem, it will merely silence the
audible alarm and clear the alarm display. You will notice if
an alarm condition exists, display #1 and display #2 LCD displays will flash the category of alarm on the
top line to remind you that an alarm exists. Also, the ATTENTION light on the front panel will remain lit.
C. DELETE key
- If a wrong number key is pressed while entering numeric data using the keypad, the
DELETE key may be pressed to delete the last number entered.
D. ENTER key

to accept your data and act upon it.

ESCAPE key will continue stepping up the display structure until the top screen of the current level of
operation is reached. To return to the main menu, the SELECT key can be pressed from any sub-
display.
