Indicator Lights
The SmartPro 450 RTI uses dual function Indicator Lights. These lights can
indicate more than one UPS or power condition, depending on whether they
illuminate constantly or flash. All Indicator Light descriptions refer to when the
UPS is connected to the wall outlet and turned ON.
2. "AC Normal/AVR" LED
This green light will illuminate constantly when the utility-supplied AC
line voltage at your wall outlet is normal. It will flash when your UPS is
automatically correcting high or low AC line voltage using AVR (Automatic
Voltage Regulation). This is a normal, automatic operation of your UPS, and no
action is required on your part.
3. "Backup/Low Batt" LED
This yellow light will illuminate constantly to indicate your UPS is providing
your equipment with battery power. Also when your UPS is providing power from
battery, the UPS's Alarm will sound once every 15 seconds until silenced. This
light will flash when the UPS's battery is nearly drained and the UPS is
initiating an automatic system shutdown. During automatic system shutdown,
the UPS's Alarm will sound once every second and cannot be silenced, though
it will turn off when shutdown is complete.
4. "Fault/Overload" LED
This red light will illuminate constantly to indicate a short circuit or other fault
in the UPS. Also, the UPS's Alarm will sound constantly for 30 seconds, then
the UPS will automatically shut down. The light will flash and the UPS's Alarm
will sound once each second when the UPS's capacity has been exceeded while
it is operating from battery power. In this case, immediately remove equipment
from the battery-supported outlets until the UPS can support the remaining
load.
5. "Replace Batt" LED
This red light will illuminate constantly if a battery self-test indicates that the
UPS battery is less than fully charged or is defective. If this occurs, turn the
UPS OFF, let it charge for 12 hours, then turn it back ON and perform a second
battery self-test. If this light comes on again, contact Tripp Lite for service.
