10.2 Manual Transfer / Preferred Source Selection
The Source Transfer option (Source Xfers) in the touch screen menu allows you to select a preferred
source. Transfers are only permitted when the voltage and current are within their proper operating
range and the sources are synchronized. The Source Transfer screen indicates the synchronization
between the two sources, while the voltage and frequency are displayed on the Mimic. See Figure 47.
Transfer is inhibited if the deviation exceeds the parameter set in the Source Set Points. See User
Settings on page 89
If your system contains the LED front panel instead of the LCD touch screen, refer to 14.2.2 - Man-
ual Transfer / Preferred Source Selection for instructions on this procedure.

NOTE
If one source will be de-energized for an extended period (hours or days), set the unit to bypass
mode for the remaining source. Without using bypass, if a failure occurs in the switch
components for remaining source, the STS2 does not have a second source to switch to and the
load would not receive power. See Maintenance Bypass on page 67 for bypass instructions.
