Figure 2-4. Distribution Board/TZ Drive Board Interconnection Diagram
Figure 2-4 shows the interconnections between the Distribution board, the TZ Drive Board, the
Pedestal Motors, and the Pedestal Position Encoders. Table 2-5 describes the interconnections
between the Distribution board and the TZ Drive Board. Table 2-6 describes the line voltage
(240VAC line to line) between the Operator's Console Power Module and the TZ Drive Board.
Table 2-7 describes the interconnections between the TZ Drive Board and the two pedestal
motors and their respective position encoders. The tables also identify the interconnection
connector and pin assignments.
