Touch the Switch button in the navigation buttons to display the Switch Settings screen (see Figure 47 ). The
Switch Settings screen is used to select or adjust parameters for sense and transfer algorithms.
Two of the three main transfer parameters—transfer algorithm and retransfer setting—are set on the Switch
Settings screen and require administrator or other higher-level authorization. The remaining choice—Preferred
Source —is set on the Home screen and requires operator-level authorization.
Use the Controls panel to select the transfer algorithm and retransfer behavior by setting these virtual
switches:
• Mode (VSS/POG) : When the VSS/POG switch is touched to be moved, the Execute button is
highlighted as a precaution. The operator must touch Execute to move the virtual switch to the opposite
position, or Cancel to revert to the previous selection. (See paragraph 2.4 Transfer Process: Algorithms ).
• Retransfer (Yes/No) : When Retransfer=Yes , the STS will switch back to the original preferred source
after an outage on that source has ended and the power on this source is within prescribed parameters.
When the
Retransfer switch is touched to be moved, Execute is highlighted as a precaution. Touch
Execute to move the virtual switch to the opposite position, or Cancel to revert to the previous selection.
The remaining parameters are Optimization parameters for the sense, transfer, and retransfer algorithms.
These parameters have been experimentally set and optimized by Eaton. NOTE: Eaton strongly recommends
that the Fast , Delayed , and Retransfer Delay settings not be changed.
