OPERATION

SYSTEM OVERVIEW

This UPS protects computers, internetworking, security, and telecommunications equipment from blackouts, brownouts, overvoltages, and surges. During normal AC operation, the UPS will quietly and confidently protect your system from power anomalies.

The UPS will charge the batteries with the UPS in the on or off position when the UPS is plugged into the wall outlet and there is an acceptable AC voltage present (100 - 140VAC). When a blackout, brownout, or an overvoltage condition occurs; the UPS will transfer to the battery mode, the On Battery indicator will illuminate and the audible alarm will sound once every five seconds indicating that the commercial power is lost or unacceptable. When the commercial power returns or is at an acceptable level, the UPS will automatically transfer back to the AC normal mode and start recharging the batteries. During an extended outage when there is approximately two minutes of backup time remaining the audible alarm will sound twice every five seconds. This Low Battery Warning is letting the user know that they should save all open files and turn off their computer. When the batteries reach the predetermined level the UPS will automatically shutdown protecting the batteries from over discharging. Once the utility power returns the UPS will automatically restart, providing safe usable power to the connected equipment and start recharging the batteries.

ON / OFF BUTTON

Press and hold the On/Off Button for one beep then release, to turn the UPS on and supply power to the load. The load is immediately powered while the UPS runs a five second self test. Press the On/Off Button for at least one second then release, to turn the UPS off. The UPS will continue to charge the batteries whenever it is plugged into a wall outlet and there is an acceptable AC voltage present.

SCROLL BUTTON

Press the scroll button to scroll through the UPS's parameters (Input/Output voltage and frequency, and the estimated battery runtime) that are displayed on the LCD.

To silence the audible alarm (Battery mode only) when the UPS is in the Battery mode hold the scroll button down for 2-seconds and then release, the Alarm Silencer icon will illuminate. Once the audible alarm was been silenced the alarm will automatically turn back on when one of the following events occur: Low Battery Warning, Overload, or a Fault condition. To turn the audible alarm back on manually hold the scroll button down for 2-seconds and then release, the Alarm Silencer icon will turn off and the audible alarm will sound. Once the UPS returns to the normal AC mode the audible alarm will reset to default.

USB COMMUNICATIONS PORT

The USB Protocol is HID. The USB port operates with the standard Windows USB drivers and does not require any additional USB drivers. Simply plug the USB cable into the UPS and the computer then follow the prompts on the screen.

POWER MONITORING SOFTWARE

The UPS comes with power monitoring software. See the software CD for the installation of the power monitoring software.

ALARMS

ON BATTERY

When the UPS is operating on the batteries, the On Battery icon will illuminate and the audible alarm will sound once every five seconds. The alarm will stop once the UPS

LOW BATTERY WARNING

The UPS will sound two beeps every five seconds when the battery reserve runs low. This condition will continue until AC returns or the UPS shuts down from battery exhaustion.

WEAK/BAD BATTERY

The UPS automatically tests the battery's condition. If the battery is weak, bad or disconnected, the Battery capacity bar graph will flash off and on and the alarm will beep three times every thirty seconds until the battery is reconnected or replaced. It is recommended that the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery condition. This alarm will be repeated until the batteries pass a self test.

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the Load capacity bar graph will flash off and on and the alarm will sound 1 beep every half second. This alarm will remain on until the excess load is removed or the UPS's self protection circuit shuts the UPS down.

UPS FAULT

When the UPS detects a hardware fault, the Fault icon will illuminate, the alarm will sound continuously and the output will turn off. The fault condition, in some instances, may be reset by turning the UPS off and then on again.
