•
An internal hardware malfunction on the preferred inlet's circuitry may
lead to a less reliable power state.
Note: The PX3TS indicates an alarm through the Alarm indicator lamps. See
Alarm Indicator Lamps (on page 118).
Tip: Per default the automatic retransfer can be performed only when both
inlets are in phase. You can disable this requirement. See
Transfer Switch (on
page 193) or Power Transfer Settings (on page 203).
Manual Transfer
The Manual Transfer button transfers power from the active inlet to the other
inlet.
In addition to performing a power transfer, a manual transfer redefines the
newly-activated inlet as the preferred inlet. For example, if Inlet 1 is both the
preferred and active inlet, pressing the Manual Transfer button causes:
•
Power transfer from Inlet 1 to Inlet 2.
•
Inlet 2, the newly-activated inlet, to be configured as the new preferred
inlet.
Tip: To remotely perform manual transfer using the web interface, see Transfer
Switch (on page 193). To transfer using the CLI, see Performing Manual
Transfer (on page 564).
A manual transfer using the front panel button is prevented if:
•
Manual Transfer button has been disabled.
•
Inlets are out of phase.
•
The other inlet's power quality (voltage or frequency) enters the Critical
state, power is lost or there is any internal hardware malfunction.
Tip: To disable the Manual Transfer button or the inlet phase synchronization
requirement, see
Transfer Switch (on page 193) or Power Transfer Settings (on
page 203).
