Operating Procedures

7.3Startup into ECO Mode

Applies only to a single module UPS and when programmed by the commissioning engineer to per- form ECO mode control of the power delivered to the load.

Follow 7.2 - Startup in Normal Mode and observe at the end of the procedure that the mimic panel bypass indicator remains green (indicating that the load is supplied by the bypass mains).

The UPS is now operating in ECOMODE.

7.4Battery Test Mode Procedures

The Battery test mode procedures transfer the UPS into shared source mode wherein approximately 15% of the rated load power is supplied by the battery and the balance by the AC input mains. There are two Battery tests to select from:

Maintenance test—verifies battery integrity and leads to a 20-percent battery discharge.

Battery Capacity test—verifies the battery’s precise capacity and leads to a full battery discharge (until “Battery Low” alarm).

The battery test procedures are password-controlled and menu-driven. The test is immediately termi- nated in the event of a battery or a mains failure and the total load power is supported from the remaining source without interruptions.

The tests can be carried out from the UPS control panel by the operator when the following conditions are satisfied:

•The load must be between 20% and 100% of rated UPS capacity

•The battery must have been float charging for 5 hours or more.

7.4.1Test Procedure

1.Select “Commands” window on the UPS control panel.

Use the right or left arrow keys to navigate to the “Commands” window.

2.Select desired Test.

Use “page” (F1) and up / down arrow keys (F2, F3) to highlight the desired test. Press “enter” (F4). When prompted, enter each password digit with up arrow (F2) and use right arrow (F3) to access next field. Press “enter” (F4) when all digits have been entered.

3.Wait until the test completes.

This tests updates the battery information used to calculate the expected back-up time (displayed during AC input failure) and the battery capacity percentage when compared to a new battery (displayed in normal mode).

4.Stop test.

If required, the test may be stopped before completion by selecting “Stop Test” in the “Commands” window.

For more details on how to operate the UPS control panel refer to 8.0 - Operator Control Panel and Display.
