MANUAL Transfer Mode (SW6 Switch):
A manual transfer may be performed from the mimic display panel, or by means of the selector switch SW6
located behind the front panel. During normal operation of the STS, selector switch SW6 must be in the AUTO
position.
Manual transfer can be performed using two different methods which can be selected by the user via the
OPTIONS MENU :
1) MAN.XFER:0-curr. (zero current mode): the transfer takes place when the output current goes to
zero
2) MAN.XFER:SWIFT (Swift transfer mode): on activation of a manual transfer, the STS monitors the
two sources for 30 seconds. If within this period the two sources are in phase with each other, the STS
transfers the load in sync using the zero-current method. If during this period the two sources are
never in sync, no switching takes place and the command has to be entered again
