Which relay affects the torque and voltage of the door motor?

The C relay is essential in determining the operational characteristics of the door motor, specifically the torque and voltage applied to it. This relay is typically involved in controlling motor functions, allowing for the proper coordination of the door's opening and closing mechanisms. When the C relay engages, it regulates the power supply to the motor, adjusting the voltage levels that influence the torque output. This function is critical for ensuring that the motor operates effectively under varying load conditions, thus guaranteeing smooth and safe door operation.

Understanding the role of the C relay in this context highlights its significance in maintaining the efficiency and performance of door operations within elevator systems. The impact on both torque and voltage plays a pivotal role in how well the door system responds to user inputs and safety features.
