8.8 LCD Menus and Data Items
The LCD menus provide access to the following categories of information and settings for the UPS.
Selecting a menu changes the information displayed in the UPS data items portion of the LCD. The
menu choices are listed below and described in detail in Table 19.
• Mains - view utility power input data: voltage, current, frequency and power factor
• TX Input - view input transformer voltages
• Bypass - view bypass data: voltage and frequency
• Output - view output data: voltage, current, frequency and power factor
• Load - view load data: load percent, output current, output power and crest factor (CF)
• System - view system data
• Battery - view battery characteristics—voltage, current, temperature and remaining time—and
messages when the battery is boost/float charging or disconnected
• Records - access the history log—displays all records in the log (newest records added at end)
• Language - select a language for LCD text (choices appear in the native language)
• Settings - configure UPS settings: adjust the display contrast, choose a format for date display,
set the date and time, set up the UPS for modem communications (baud rate, address, mode and
phone numbers to dial for alarm notifications) and change the password
• Command - start or stop a battery maintenance test, battery capacity test or system test
• Version - view firmware versions for the inverter, rectifier and software display board and the
model information for the UPS
Figure 45 shows a menu tree of the options available from the LCD menus.
