Operating Modes

On-Line (Run operation)

The following illustration shows circuit power flow when the UPS is operating normally in the On-Line mode. The UPS rectifier, including a boost chopper circuit, converts AC input power to DC power. The boost chopper circuit maintains a constant voltage, with current limiting, for charging the batteries. It also supplies a DC voltage of the proper level to the inverter section. The inverter section generates a high quality sinusoidal output voltage. The unit’s batteries are always maintained in a constantly charged state when the UPS is in the run operation mode.

Static-Bypass (Stop operation)

If the UPS unit is severely overloaded or develops an internal fault, power flow is automatically switched from the unit’s main circuit to the bypass circuit. Power flow through the bypass is shown in the following illustration. This change-over occurs automatically in phase in less than one-quarter cycle of the input waveform. The switching period is not long enough to cause interruptions to occur in most loads.

•If the power flow is transferred to the bypass circuit because of an overload and that overload condition ends within a specified period of time then the power flow will be transferred back to the On-Line mode (run operation) automatically.

•If the power flow is transferred to the bypass circuit due to an external fault the UPS will shut down power through the bypass to the load and indicate a system fault message.

•If the power flow is transferred to the bypass circuit due to an internal fault the UPS will continue to supply power to the load through the bypass and indicate a system fault message (see system fault messages on pages 53–54).

•If the power flow is transferred to the bypass circuit due to an overload condition (see system warning messages on pages 54–55), then the power flow will automatically transfer from the UPS’s bypass circuit back to the inverter circuit after removing the overload if set to do so (AutoReXfer parameter (Cmd ID 662)).
