Liebert 1000kVA manual Battery cycle monitoring summary screen

Operation

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).
