You are tasked to design the safety belt system for a theme park roller coaster ride. The roller coaster ride has the following inputs: • A motion sensor that provides a high input signal when the roller coaster is moving. • An "arrival" sensor that provides a high input signal when the ride is parked at the docking station. • A manually operated safety belt release button (normally open). • A manually operated safety belt lock button (normally open). The safety belt system should only unlock (by activating it) at least five seconds after the rolle coaster arrives at the docking station and stops moving, and when the operator continuously presses the manual release button for at least two seconds after the roller coaster has arrived The safety belt system should remain unlocked until the lock button is pressed. Design the ladder diagram for such a system. Draw your ladder diagram on paper or on a computer then attach a clear image or screenshot of your work to this question. Provide comments explaining your diagram where necessary.

Question
You are tasked to design the safety belt system for a theme park roller coaster ride. The roller
coaster ride has the following inputs:
• A motion sensor that provides a high input signal when the roller coaster is moving.
• An "arrival" sensor that provides a high input signal when the ride is parked at the docking
station.
• A manually operated safety belt release button (normally open).
• A manually operated safety belt lock button (normally open).
The safety belt system should only unlock (by activating it) at least five seconds after the roller
coaster arrives at the docking station and stops moving, and when the operator continuously
presses the manual release button for at least two seconds after the roller coaster has arrived.
The safety belt system should remain unlocked until the lock button is pressed.
Design the ladder diagram for such a system. Draw your ladder diagram on paper or on a
computer then attach a clear image or screenshot of your work to this question. Provide
comments explaining your diagram where necessary.
