O P E R A T I O NQualify Bypass. By default, a switching to bypass mode is only thenpermitted if the bypass is within the following specifications:The bypass voltage lies between the set "Lower bypass voltagethreshold value" and the "Upper bypass voltage thresholdvalue"The bypass frequency lies within the nominal frequency witha deviation of max. ±5HzThe inverter is synchronised with the bypass if the setting"Unsynchronised Transfers" setting is disabledYou can prevent the bypass ("Never") or always allow ("Always")without the specifications are being checked. In the "Always on UPSFault", a switch into bypass mode always occurs for a fault of theUPS system. Otherwise, the mode corresponding to the standardoperating mode setting is selected.Synchronisation window: The UPS system attempts to synchroniseitself with the bypass if the bypass frequency lies below the valuespecified for the "Synchronization Window" setting. If the bypassfrequency lies above the set value, the UPS system switches to thenormal frequency. The synchronisation window in bypass modeamounts to ±5Hz. If the synchronisation is disabled ("Sync Disabled"),the UPS system will only synchronise in bypass mode.Unsynchronised transfers. The standard setting permits andunsynchronised switch to the bypass mode. You can configure thesettings so that these types of mode changes are not allowed.This setting can be disabled by the "Qualify Bypass" setting.4.7 Configuring load segmentsLoad segments are groups of output power outlets of the UPS systemwhich can be controlled by the DataWatch software or via thedisplay and facilitate a physical shut down and starting of the load.For example, you can allow important devices of the system to remainin operation during a power failure while others are shut down.You can save battery current using this function.108 / 222XS700-XS3000_manual_ger_eng_it_V1.1.0.doc ...........................................................
