Y1 Y2

1. Control purpose

 The entry/exit of the underground car park is a single lane passage which needs the traffic

lights to control the cars. Red lights prohibit cars entering or leaving while green lights allow

cars to enter or leave.

 When a car enters the passage from the entry of the ground floor, the red lights both on the

ground floor and the basement will be ON, and the green lights will be OFF. Any car entering

or leaving is prohibited during the process till the car passes through the passage

completely. When the passage is clear, the green lights will be ON again and allow other

cars entering from the ground floor or the basement.

 Similarly, when a car leaves the basement and enters the passage, any car entering or

leaving is prohibited till the car passes from the passage to the ground completely.

 When a PLC runs, the initial setting of traffic lights will be green lights ON and red lights

OFF.
