between the Main Control Board, and the Power Board. The PSI/Switcher
board also provides the following:
Distribution of DC logic power to the Main Control Board.
Three-Phase line synchronization signals to the Main Control Board.
Contactor and other logic control interface with the Main Control
Board.
Rectification and Regulation of the external 115VAC power supply to
produce 5VDC and +/–12VDC control voltage.
All current related feedback scaling circuitry.
Customer basic interface for 115VAC.
Field Current Range jumpers.
Jumper selection for 24VDC or 115VAC for reset, motor thermal and
ECOAST.
