Refer to figures "1" and "2" of the basic synchronous transmission system shown in the illustration. Figure "1" shows a properly connected system where the receiver TR remains in correspondence with the transmitter TX. In figure "2", although properly zeroed, the receiver goes out of correspondence with the transmitter due to improper connections resulting in reverse torque direction. Which connection error results in this behavior? Illustration EL-0149

AI Explanation

The correct answer is A. The connection error that results in the receiver going out of correspondence with the transmitter due to improper connections and reverse torque direction is A. This is because the polarity of the connections between the transmitter and receiver must be properly aligned for the synchronous transmission system to function correctly. If the polarity is reversed, as shown in Figure 2, the receiver will go out of correspondence with the transmitter, leading to the observed behavior. The other answer choices (B, C, and D) do not directly address the specific connection error that causes the issue described in the question.
