LCD SCREEN
The user interface consists of a back lit LCD screen having:
•
4 lines with 20 characters (standard version for Latin characters).
and
•
6 keys (the function is described for each operating mode).
The operation is extremely simple and is structured on three important main menus related to the UPS
operation, as follows:
metering
A UPS must offer some metering information for the user to be able to examine the
operating status at any time.
alarms
In the event of Utility failures or abnormal functioning, the UPS must keep a history of
what has happened as a series of events.
parameters
The user must be able to program certain functions of the UPS (user parameters,
accessible without password) to his needs.
LCD screen standard version
The 3 buttons existing on the left side of the screen are used to activate the operating modes, while the
buttons on the right side are used to carry out functions inside these operating modes.
