Operation

Values for Calculated Total Time and Calculated Time Remaining will appear on the screen approxi- mately two minutes after the beginning of the discharge event. Calculated Time Remaining also appears on the Present Status Report screen. Both Calculated Total Time and Calculated Time Remaining will be updated every six seconds, reflecting actual load changes and battery condition. When the Calculated Times become available, they will be displayed in place of the Battery Discharg- ing message on this screen.

The Battery Time Remaining graph and the Calculated times are extremely helpful to the operator who has the discretionary authority to order load-shedding activities. The Liebert Series 610 automatically samples battery voltage and load current and recomputes every six seconds. This gives the operator fast and accurate feedback on efforts to extend battery time remaining by shutting down non-critical loads.

NOTE

While every effort has been made to make the Rated and Calculated Time Remaining values as accurate as practical, these values must be regarded as approximations. At the beginning of the discharge cycle, the Calculated times could be off by as much as ±20% due to such variables as battery initial charge, age of battery and the subsequent load-shedding activities of the operator. Within a few minutes, however, these calculations should settle into their design accuracy of ±10%, with the end-of-discharge tolerance being +0, -10% of actual observed time. In addition, the operator can adjust the settings affecting Rated Total Time after gaining experience with the actual battery and connected load.
