Pop-up prompt windows appear when the user must confirm a choice or perform an operation. This
section describes the pop-up windows.
2.13.1 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
synchronization with the bypass, and the output can only transfer
to inverter 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 automatically. At the same time, the prompt window will close.
2.13.2 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 system must let the user to
confirm and accept the power interruption danger before pressing
the INVERTER OFF button 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 disappear soon.
