During the 2nd slowdown closing sequence, R5 bypasses what around the door motor armature?

During the 2nd slowdown closing sequence, R5 bypasses high current around the door motor armature to protect the motor. This occurs when the door is closing, and it is crucial to ensure that the motor does not experience excessive current, which can lead to overheating or damage. By bypassing high current, the system maintains a safe operational environment, allowing the motor to function efficiently while minimizing the risk of electrical failure.

Understanding this process is important as it illustrates how safety mechanisms are integrated into elevator systems to manage the performance of door operators. If high current were allowed to pass through the motor armature during the closing sequence, it could lead to equipment failure or safety hazards. Thus, R5 serves a key role in ensuring operational safety and longevity of the components involved in the system.
