System Modes
The system mode indicates the output status of the complete UPS system including the surrounding switchgear and indicates which source supplies the load.
Inverter Operation
In inverter operation the load is supplied by the inverters. The UPS mode can be in either normal operation or battery operation when the system operation mode is inverter operation.
Requested Static Bypass Operation
When the system is in requested static bypass operation, the load is supplied from the bypass source. If a fault is detected, the system will transfer to inverter operation or forced static bypass operation.
Forced Static Bypass Operation
The system is in forced static bypass operation following a command from the UPS system or because the user has pressed the inverter OFF button on the UPSs. During forced static bypass operation, the load is supplied directly by the bypass source with unconditioned power.
Maintenance Bypass Operation
In maintenance bypass operation, the load is supplied directly by the bypass source with unconditioned power.
ECO Mode
ECO mode allows the system to be configured to use requested static bypass operation, with the load supplied through the bypass, as the preferred operation mode under predefined circumstances. The main advantage of ECO mode is a reduction in the consumption of electrical power. In case of interruption to the utility/mains supply, the UPS transfers to inverter operation for an uninterrupted supply of the load.
