8.13Pop-Up Windows

Pop-up prompt windows appear when the user must confirm a choice or perform an operation. This section describes the pop-up windows.

8.13.1 From Bypass to Inverter Mode With Power Interruption

If the bypass voltage or frequency exceeds the synchronized range and utility voltage or frequency is normal, the inverter cannot be in syn- chronization with the bypass, and the output can transfer to inverter only after an interruption of about 15ms when the user presses the INVERTER ON button. Before transferring, the system will let the

user confirm whether the interruption can be accepted, as shown at right. If the bypass voltage returns to normal before the user makes confirmation, the UPS will transfer to inverter mode auto- matically. At the same time, the prompt window will close.

8.13.2 From Inverter to Bypass Mode With Interruption

If the bypass voltage or frequency exceeds the synchronized range and the UPS is in inverter mode, the user must confirm and accept the power interruption danger before pressing the INVERTER OFF but- ton to shut down the output of the inverter. The user can also cancel the shutdown operation, as shown at right. If the bypass voltage returns to normal before the user makes the confirmation, the UPS

will transfer to bypass operation mode automatically, and at the same time the prompt window will close disappear soon.

8.13.3System Self-Test

When a system self-test is completed, a pop-up window reports the results of the test, as shown at right.

•Press the F4 (Enter) key and the pop-up window closes.

System Self-Test finished,

Everything is OK

8.13.4 Battery Capacity Test Confirmation

When a battery capacity test is started from the Command menu, the battery will be discharged to low-battery warning level. The Liebert NX asks for confirmation before the test is started, as shown at right.

•To confirm the choice and begin the battery capacity test, press the F4 (Enter) key and the pop-up window disappears.

•To cancel the test, press the F1 (ESC) key. The pop-up window closes.

NOTE

Battery will be depleted,

Confirm or cancel

For a battery capacity test to function properly, the load must be between 20% and 100%.

8.13.5Battery Self-Test Aborted, Condition Not Met

When a battery capacity test is started from the Command menu and the battery self-test criteria are not met, the Liebert NX will not per- form a battery test. User should check whether the battery state is boost charging and whether the load level is greater than 20 percent.

•Press the F4 (Enter) key and the pop-up window closes.

Battery Self-Test aborted, Conditions not met

8.13.6Battery Refresh Charge Aborted, Condition Not Met

When a battery refreshening charge is started from the Command menu and battery refreshening condition fails to meet requirements, the Liebert NX will not perform a battery refreshening charge. User should check if boost charging condition has not met the test criteria, such as (No battery, charger failed, etc.).

•Press the F4 (Enter) key and the pop-up window closes.

Battery Refresh Charge aborted,

Conditions not met
