I only need help with the programming part, I can wire the schematic up. You are required to write a program to run a garage door drive motor using the attached schematic in figure 1. Pressing push button 1 should cause the drive motor to run in the up direction. The drive motor should continue to run after push button 1 is released until limit switch 1 is actuated or push button 3 is pressed. Pressing PB2 should cause the drive motor to run in the down direction. The drive motor should continue to run after Pb2 is released until limit switch 2 is actuated or PB3 is pressed. The up and down motor starters should have interlocks in your program that only allow one of the motor starter outputs to be on at any given time . It should take no longer than 5 seconds for the door to open or close. So, if the drive motor runs in either direction for more than 5 seconds the alarm lamp L1 should illuminate indicating that there is a problem. Once the alarm light comes on, it should stay on until PB3 is pressed to reset the alarm. Also, if the alarm light is on, the drive motor should not be allowed to run until the alarm is reset. Finally, the garage door opener chain must be frequently greased. It should be greased after the drive motor has been run 5 times in either direction. So, after the drive motor runs 5 times, the PM required lamp (L2) should illuminate. The PM required light should stay on until SS1 (selector switch 1) is momentarily switched left and back to center resetting the PM counter. The door is allowed to continue operation even though a PM is required.
