Logging and time-stamping (cont.)

total time with Tbatt > 25° C (h):

this is the total time of operation with

the battery temperature greater than

25° C since initial startup of the UPS.

It is expressed in hours;

last reset: this is the date that the

information was last set to zero by the

Teleservice function;

elapsed backup time (min): this is

the total time of operation on battery

power since the last reset. It is

expressed in minutes.

nb of backups: this is the number of

times the load was supplied by the UPS

from battery power since the last reset;

nb of backups < 1 min: this is the

number of times the load was supplied

by the UPS from battery power for less

than one minute, since the last reset;

1 min < nb of backups < 3 min: this

is the number of times the load was

supplied by the UPS from battery

power for more than one minute and

less than three minutes, since the last

reset;

nb of backups > 3 min: this is the number of times the load was supplied by the UPS from battery power for more than three minutes, since the last reset;

nb of overloads < 5 s: this is the number of times the UPS was overloaded (output current greater than In) for less than five seconds, since the last reset;

nb of overloads > 5 s: this is the number of times the UPS was overloaded (output current greater than In) for more than five seconds, since the last reset;

nb of times TBatt. > 25° C: this is the number of times the battery temperature was measured at over 25° C, since the last reset.

Consulting recorded measurements

Recorded measurements are presented in the same manner (see opposite):

the lists indicate the last 30 measurements recorded for the given parameter. The chronological order of the measurements is indicated in the figure opposite;

the most recent measurement is presented first, in the upper left-hand corner of the list. The following measurement is listed just below, and so on until the 30th value listed in the bottom right-hand corner of the list;

the period T between two successive measurements is 30 days.

The displayed measurements are instantaneous values.

Note: when this screen is selected, approximately ten seconds are required to call up and display the information.

If the number of measurements is greater than 30, only the last 30 (the most recent) are displayed.
