Audible Buzzer, LCD Overview | Emerson 480V specs

Operator Control and Display Panel

8.4Audible Buzzer

The buzzer produces three types of sounds:

•Single beep - when any control button is pressed

•Single beep repeating every two seconds - the system has a general alarm

•Continuous - the system has a serious fault

If the buzzer makes no sound, the system may be operating properly, or an alarm may have been silenced manually.

8.5LCD Overview

The LCD on the front panel has five main sections, as shown in Figure 44. Press the F1 key below the LCD to scroll through these sections.

•UPS System Information - view UPS name and model, date and time, overall status (see Table 18).

•LCD Menu - choose a category of data items to appear below the menus (see Table 19).

•Data and Settings - view data items for the selected menu (see Table 19).

•Current Status Messages - check any active UPS event and alarm messages (see Appendix A).

•Navigation Key Icons - look at the icon above each navigation key to determine how the key operates when pressed (see 8.6 - Navigation Keys).

The LCD displays alarm information in real time. After appearing in the current status section of the LCD, status messages are stored in the history log—512 records can be stored and retrieved.
