Emerson U /400/S/6P, 400KVA Battery Test Mode Procedures, System Test Procedure, Test procedure

42 Chapter 5 Operating Instructions

Follow previous 5.2 Start-UP Procedure (Into Normal Mode) and observe at the end of the procedure that bypass LED on the operator control and display panel remains green (indicating that the load is supplied by the bypass mains).

The UPS is now operating in ECO mode

5.4 Battery Test Mode Procedures

The Battery test mode procedures transfer the UPS into shared source mode wherein approximately 15% of the load power is supplied by the battery and the balance by the AC input mains.

Battery test type and preconditions

1. There are two battery tests to select from:

zBattery maintenance test: verifies the battery integrity and leads to the battery being partly discharged (20%).

zBattery capacity test: verifies precisely the battery capacity and leads to the battery being fully discharged (until Battery low prewarning alarm)

2.The tests can be carried out from the operator control and display panel of the UPS by the operator when the following conditions are satisfied:

zThe load must be between 20% and 80% of rated UPS capacity.

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

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

Test procedure

1.Select the Command menu on the LCD screen on the operator control and display panel of the UPS. Use the right or left arrow key to navigate to the Command menu.

2.Select the desired test (the Battery maintenance test or Battery capacity test option).

Use the Shift key (F1), up and down arrow keys (F2, F3) to highlight the desired test. Press the Enter key (F4).

When prompted, enter each password digit with up arrow (F2) and use right arrow (F3) to access next field. Press the Enter key (F4) when all digits have been entered.

3. Wait until the test completes.

This test updates the battery information, including the battery autonomy time (battery discharge duration during AC input failure) and the battery aging coefficient (battery capacity percentage when compared to a new battery).

4. Stop the test.

If required, the test may be stopped before completion by selecting Stop testing on the Command menu.

5.5 System Test Procedure

The UPS test procedure checks the control functions of the UPS, the mimic flow chart LEDs and the audible alarm. This self-test is password controlled and menu driven. It can be carried out from the operator control and display panel by the operator and takes 5 seconds.

Test procedure:

1.Select the Command menu on the LCD screen on the operator control and display panel of the UPS. Use the right or left arrow key to navigate to the Command menu.

2.Select the System test option.

Use the Shift key (F1) and up and down arrow keys (F2, F3) to highlight the desired test. Press the Enter key (F4).

When prompted, enter each password digit with up arrow (F2) and use right arrow (F3) to access next field. Press the Enter key (F4) when all digits have been entered.
