Eleisha,
Although I appreciate your interest in understanding your elevator system, i must warn you that elevators are complicated equipment. Professionals spend years in training to identifiy the hazards. As well as a lifetime developing the skills needed to understand the ever changing industry.
You have not indicated in your profile how you are related to the elevator industry. You do seem to have some knowledge of the industry (I read your MCE posts).
Now reading this thread and your previous threads, I believe you are a building owner or manager. If you are I would be glad to advise you as such.
Please keep in mind "as we all should" when you post asking for this type of information you are accepting the responsibility and liability of your actions. You are also asking the members here to do so as well.
