When the pit directional limit switch is actuated, what direction will the car be allowed to run?

1. Up

2. Down

3. Sideways

4. In place

The correct answer is: Up

When the pit directional limit switch is actuated, it primarily functions as a safety feature for the elevator system, indicating the lowest permissible position of the car within the hoistway. If this switch is activated, it typically allows the elevator car to move upwards. This ensures that the car does not descend further, which could be hazardous or lead to operational issues. The function of the pit limit switch is to prevent the car from going beyond the set limit, thus ensuring safe operation by controlling the upward movement when the switch is activated. This safety mechanism is critical in maintaining the car's position and preventing accidents or mechanical failures when the elevator is at its lowest point. Consequently, when the switch is activated, allowing movement in only the upward direction is standard procedure within elevator operations.
