After the UPS has been successfully started, the system will be in the normal 'AC
Input Mode' of operation. The LCD screen will automatically display the main MONI
(monitor) function. If the MONI key is pressed at this time the screen output will not
change. The MONI function automatically monitors the entire UPS system. The LCD
screen will automatically switch "off" after a period of keypad inactivity and switch
"on" if any key is pressed. It will switch "on" automatically during battery discharge or
if an abnormality develops in the system (see "Settings for LCD Display Duration").
All system 'line' messages will be displayed from MONI mode when abnormal
operating problems are detected. If AC input power is available and the UPS is
operating normally, the following system message is displayed:
- UPS ON-LINE -
OUTPUT VOLTAGE= 208V
CURRENT=100/100/99%
DATE (DAY) TIME
If an AC input power failure occurs, and no abnormal operating conditions are
present, the UPS switched to standard 'Battery Backup Mode'. The following system
message is displayed:
- BATTERY BACKUP –
