PSI/Switcher Board The primary function of the board (Figure 2.7) is to provide interface
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.
