Based on the provided information, here's how the input and output devices function in the described scenario:
Input Devices:
Position detection (S1): This sensor detects the position of the gear. When the gear is moved towards S1, this sensor will detect the gear.
Lower limit of oil (S2): This sensor monitors the oil level in the lubricating tank. When the oil level drops below a certain threshold, the sensor S2 will detect it.
Output Devices:
Electromagnetic valve for oil supply (V1): When the gear is detected by the sensor S1, the electromagnetic valve V1 will be signaled to open. This valve controls the supply of oil. It will open for a short period of time, allowing a predetermined quantity of oil to flow.
Oil shortage alarm indicator: When the sensor S2 detects that the oil level in the lubricating tank is low, the oil shortage alarm indicator will be turned on. This indicator serves as a visual or audible alert to indicate the need for oil replenishment.


In summary, when the gear is moved towards S1, the position detection sensor S1 will trigger the electromagnetic valve for oil supply (V1) to open temporarily, supplying a specific amount of oil. On the other hand, when the oil level in the lubricating tank drops below a certain level, the lower limit of oil sensor (S2) will activate the oil shortage alarm indicator to indicate the need for refilling the tank.
