Operator Control and Display Panel

9.6Navigation Keys

The navigation keys on the front panel—F1 through F4 and Help—are used to access the LCD to view the current status and other information about the Liebert® APM.

Navigation key icons on the LCD appear above each key to indicate its operation (see Table 26). The keys are “soft keys” that can change functions according to the icon.

Use F1 to move to the home portion of the LCD.

Use F3 and F4 as cursor keys to move left and right or up and down, depending on the icons dis- played above the keys.

Use F3 and F4 on the display simultaneously to view individual Module information such as Input and Output conditions and individual Module Firmware versions

Use F2 as an ESC key.

Use HELP to access help information on the LCD or to enter a choice.

9.7LCD 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 27.

Mains - view utility power input data: voltage, current, frequency and power factor

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, remaining time and capac- ity—and messages when the battery is boost/float charging or disconnected

Events - view the events log—displays all recent events added to the log (new records added at end)

Records - access the history log—displays all records in the log (new 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

Run Time - view available backup time for the UPS and bypass

Version - view firmware versions for the inverter, rectifier and software display board and the model information for the UPS
