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 on units without Optimized Transfer. Units with the

Optimized Transfer option do not require the sources to be synchronized to make a manual transfer.

The Source Transfer screen indicates the synchronization between the two sources, while the voltage

and frequency are displayed on the Mimic. See Figure 46. 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 -

Manual 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 Liebert 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.
