The car must run at which speed when using temporary run buttons?

When using temporary run buttons, the car must operate at leveling speed. Leveling speed is specifically designed to ensure the elevator accurately aligns with the floor level, providing a smooth and safe transition for passengers entering or exiting the car. This speed allows for precise control of the elevator movement, reducing the risk of abrupt stops or overshooting the landing.

Using leveling speed is crucial in temporary operations because it prioritizes safety and efficiency, especially in situations where the elevator may not be under regular control. The other speed options, such as maximum speed or high speed, could lead to less control and increased risk for users, undermining the primary goal of safe elevator operation in temporary conditions.
