✦ Synopsis

The purpose of this manual was to design and implement a four floor elevator
control system. Each floor was to have its own illuminated push button to call the
elevator to go to the desired floor. The elevator door was to be emulated with the use of a 3 V DC small toy motor that opened, stayed open, and reversed a few seconds after being called upon. Also, a 12 V DC motor was used to hoist the car with mechanical limit switches, which were used to indicate when the elevator was at the floor, in position to open. The final aspect of this experiment was to intelligently organize the ladder logic to make the troubleshooting easier. Hence the purpose behind of developing a manual like this is an attempt to make learning
Programmable Logic Controllers fun!
