400 Using the FERRUPS’ Front Panel Lights

The FERRUPS display includes three lights that show you the status of FERRUPS operation.

Alarm Light

Battery Light

Line

(AC Input)

Light

The red Alarm light means the UPS has detected a problem. When this happens, the display shows an alarm message, and the UPS beeps the Morse Code for the alarm. See Section 600.

The yellow Battery light means the UPS is operating on battery power, either because there is a power outage or because the available AC input power is not usable. When this happens, the display shows “On Battery ,” the runtime, and the battery voltage. (You can press the bottom right buttton to switch to the menu display; see Section 501.) The UPS will continue to run on battery power until the power problem ends or the UPS’ batteries discharge. If the batteries discharge, the UPS will sound alarms shortly before shutting down.

The green AC Line light means the UPS is using the available AC input power. The UPS conditions the power before providing output to your equipment. While the FERRUPS is using AC input power, it displays “System Mode Auto” and whether the battery char ger is on or off. You can press the bottom right button to switch to the menu display; see Section 501 for more information.

500 Using the Display

This section explains how you can use the FERRUPS’ front panel display to get more information about FERRUPS operation or to change settings. You can use the display to enter a password, display and change system settings (parameters), and display system logs.

501 Displaying and Moving through the Menus

The FERRUPS display groups information in 7 different menus. See the Menu Map on page 11; the items numbered 1-7 in the left column of this diagram are the top-level menus. For example, 2 System Status is the System Status menu. To the right of this menu in the Menu Map, you will notice a list of items that are part of this menu. Some menus, like menu 5, System Config, have submenus (Gen Sensitivity; Sys Test, Inv, Chg; System Mode Control; Alarm and Shutdown; and Calibration Factors). Others simply have lists of items directly below the top level menu.

When you start the UPS, the display shows “Best Power,” the mode, and whether the char ger is on or off. To change to the menu display, press the bottom right button (below the word “Menu” on the bottom line of the display). The display will show the top level in the first menu (1, Enter password) as shown in the drawing. Ten minutes after you last press a button, the display will switch out of menu mode and show the normal display (see Section 400).
