LCD DISPLAY

The LCD can display much more information than can the LEDs. In order to

make the display sharp and readable, the LCD is back-lighted. But to further

prolong the life of the LEDs, the Central Processing Unit (CPU) will cut off

power to the LEDs 3 minutes after the last keystroke of UP, DOWN or ENTER is

pressed. The backlighting will resume if the UP, DOWN or ENTER key is

subsequently pressed. Page displays of the LCD are described below. This screen

will refresh once the system power is enabled (i.e. the default screen).

The first row will display the greeting text set by the factory. Changing the text of

this row is not recommended. The parameter no. (P/N), serial number (S/N), and

the identification number (ID) are displayed in the second row. While the third

row will display the KVA rating, input rating and output rating of the UPS.

Changing the parameter number of the second row will also change the rating

displayed in the second row (rating is automatically generated by CPU inside the

UPS according to the P/N number).

WARNING: Never change the parameter number yourself, because some

parameters will be changed accordingly.
