Chapter 6. Signal Path
6
The following description of the TC–10B signal path is in accordance with the Functional Block Diagram
(see Figure 6-1) and the Rear Panel previously shown (in Figure 3-1). You may find this discussion of
signal path useful during Installation / Adjustment Procedures (Chapter 5) and Design Verification Tests
(Chapter 7).
NOTE
The Vdc is received from three (3) available groups
of station batteries:
• 38–70Vdc (48–60Vdc nominal)
• 88–140Vdc (110–125Vdc nominal)
• 176–280Vdc (220–250Vdc nominal)
