The Summary screen (Figure 27) shows Total Number of Discharge Cycles, Accumulated Battery
Time, Accumulated Battery Amp Hours, Accumulated Battery Kilowatt Hours and Battery Tempera-
ture. During a battery discharge event, the screen changes to show information about the present dis-
charge cycle. The screen displays Active Cycle Time in place of Accumulated Battery Time and shows
Active Battery AH and Active Battery kWH instead of accumulated values.

Figure 28 shows a typical detail screen for the 91-240 Seconds Discharge category. This information
can be collected remotely, through the optional communications board and modem, by a remote termi-
nal or a personal computer equipped with a modem and communications program. See 3.2.15 - Com-
munication Interfaces for more information.
NOTE
This information is applicable to systems with separate batteries for each module. If the
modules share a common battery, select one module to do the monitoring and disregard
the other(s).
