5.0 Operation

5.7 Extended capabilities

The following sections briefly describe the UPS’s extended capabilities. These ad-

vanced functions are accessed by a computer running optional PowerDoctor or

PowerChute plus UPS monitoring software. See the UPS monitoring software literature

for more information on the application of these functions.

Note: The extended capabilities of the UPS and operation of UPS monitoring software

may be altered or amended without notice.

5.7.1 Status reporting

● General - When queried, the UPS reports its electronics serial number, version

number, date of manufacture and date of last battery replacement.

● Operating status - When queried, the UPS reports its current operating status.

Reported modes includes on-line, on-battery, Smart Boost, overloaded output, low

battery, shut down and internal fault.

● Test results - When queried, the UPS reports the stored results of the last automatic

or manually initiated battery test. The user may also test the operation of the UPS’s

visual and audible indicators.

5.7.2 Monitoring

● Run time - When on-battery, the UPS continuously monitors the remaining run time

in minutes. Available run time is monitored when operating on-line.

● Line voltage and frequency- The UPS continuously monitors the rms line voltage

and the line frequency. Transients lasting less than 0.5 seconds are not reported. This

information can be logged using UPS monitoring software, plotted using any spread-

sheet application and used to identify transient power quality problems over extended

periods.

● Minimum and maximum line voltage - The minimum and maximum line voltage is

recorded to provide a snapshot of power quality over a user specified interval.

Transients lasting less than 0.5 seconds are not recorded.

● Output power - The UPS continuously monitors the power consumed by the load.

The value given is a percentage of the full load rating of the UPS. This information can

be logged using UPS monitoring software, plotted using any spreadsheet application

and used to determine load usage over extended periods.
