MODES OF OPERATION

Normal Mode

During Normal mode operation, the Power- Sure PST supplies conditioned, computer- grade power to the connected equipment: mains power passes through the TVSS cir- cuitry, EMI/RFI filters and then through the Transfer Switch to the connected equipment.

When the UPS is in Normal mode, the Mains/Battery Indicator illuminates green.

+-

Continuous indicator illumination denotes Normal Mode

The PowerSure PST continuously monitors the batteries to maintain them in a fully charged state. The battery charger operates whenever AC power is present, even if the UPS is switched off. The UPS per- forms an automatic battery test after it has been operating continu- ously for two (2) weeks.

Battery Mode

The UPS switches to Battery mode in the event of an extreme voltage/frequency condi- tion or complete mains failure. The battery system supplies power through the Inverter to generate power for connected equipment. When the UPS is in Battery mode, the Mains/ Battery Indicator flashes green and an alarm sounds every 5 seconds.

Battery Mode

When a low battery condition occurs, the Battery Indicator continues to flash green and the alarm sounds every half-second. Low battery warning is initiated when approximately two (2) minutes of battery run time are remaining. For more information, refer to Trouble- shooting section.

! CAUTION

Turning off the UPS while in either Normal mode or Battery mode will result in the loss of output power.

NOTE

Once mains power is restored, the UPS resumes normal operation. At this time, the battery charger begins recharging the battery. The UPS is capable of OFF-State charging, i.e., with mains power, the UPS will charge the batteries as long as it is plugged in.
