Operation Modes of Operation ON LINE MODE: This is the standard operating mode for your UPS. In On line mode, the UPS provides continuously regulated AC output and recharges the battery system as needed. If input power becomes unstable, the UPS will automatically maintain sine wave output from battery reserves. ON LINE MODE LEDs: AC INPUT, AC/DC, DC/AC & OUTPUT LEDs on. ON LINE MODE LCD SCREEN: Operating mode and UPS load information Note: A flashing INPUT LED indicates that input power is available, but is either not stable enough or of the wrong frequency to utilize in a bypass capacity. (FLASHING) ON LINE MODE LCD VIEWING OPTIONS: When first entering On Line mode, the LCD screen will display load information in percentage and kilowatt units. To display additional information screens, tap the SCROLL DOWN ("v") button repeatedly. Additional screens include: Kilowatt hour usage, Kilowatt capacity remaining, Runtime-remaining in minutes, Battery voltage and charge percentage, Output voltage and frequency, Input voltage and frequency, Load Power Factor and Load percentage plus kVA capacity. ON BATTERY MODE: In this mode, the UPS is providing battery-derived sine wave AC output to connected equipment. Battery mode is an automatic response to power failure or extreme voltage fluctuation while the UPS is running in On line or Economy modes The UPS can also be cold-started into Battery mode manually during a power failure by pressing and holding the ON/TEST button (see how-to section). The UPS will automatically return to on-line or economy modes once mains power is restored and stable. To silence the audible alarm, press the ON/ MUTE button. The alarm will re-sound to warn of low battery conditions. As batteries become fully depleted, the UPS alarm will sound for 5 seconds continuously and AC output will turn off. The front panel LCD will display "OUTPUT OFF/BATTERY LOW" for up to 5 minutes before automatically turning off. ON BATTERY MODE LEDs: BATTERY, AC/DC, DC/AC & OUTPUT LEDs on. ON BATTERY MODE LCD SCREEN: Operating mode and UPS load information ON BATTERY MODE LCD VIEWING OPTIONS: When first entering ON BATTERY mode, the LCD screen will display load information in percentage and kilowatt units. To display additional information screens, tap the SCROLL DOWN ("v") button repeatedly. Additional screens include: Kilowatt hour usage, Kilowatt capacity remaining, Runtime-remaining in minutes, Battery voltage and charge percentage, Output voltage and frequency, Input voltage and frequency, Load Power Factor and Load percentage plus kVA capacity. BYPASS MODE: BYPASS is an operating mode where the UPS is passing unprocessed input power directly through to the output. BYPASS MODE can engage on an automatic basis (AUTO-BYPASS) or as an emergency UPS operating mode that maintains output to connected equipment in case of UPS overload or internal component failure that would otherwise cause connected equipment to lose power. AUTO-BYPASS MODE operation resulting from sudden UPS overload as the UPS is running in ON LINE MODE will automatically reset, once the output load is reduced. BYPASS MODE resulting from internal UPS failure may not automatically reset, and if the message persists, users should contact Tripp Lite for troubleshooting or repair options. Regardless of the cause, the UPS will not provide battery backup anytime the LCD screen reports BYPASS MODE. BYPASS MODE is also displayed on the LCD screen when the UPS is configured via the LCD STANDBY MODE screen to ENABLE BYPASS OUTPUT. Once this preference is set, the UPS will alternate between BYPASS MODE with loading information and PRESS ON KEY TO TURN UPS ON. In this mode, the UPS is providing standby mode operation with power at the outputs and the charger is operational, but the UPS will not provide backup if power fails in this mode. 11 13-07-015-9332C3.indb 11 7/26/2013 11:16:15 AM
