Question on elevator safety : LUSENET : Elevator Problem Discussion : One Thread

Dear Sir,

I am doing a research on elevator safety.

I have a problem finding information about safety of control circuits containing microprocessor and some other ICs. I didn't find any information whether companies simulate errors on the main board or they just simulate errors or damages on processors but not on the other ICs.

Here is my question: Is it possible that as a result of any IC damage elevator will move, but the door will stay open? Are there any law regulations?

Yours faithfully, Zoran Kovacevic

Have e-mailed Mr Kovacevic a lengthy e-mail on elevator safety and links for U.S codes etc. The e-mail is too lengthy to post on forum but I can send a copy to if you want May include it in my home page in the future. Any one elese with knowledge of codes or safety related issues may want to respond.

Zoran, While ASME A.17 is "code of the land" it is that only that in and state politicially driven ( like Minnesota) code bureaucracies have the power to alter, and even omit code items they find ( or told to find) to be expensive to building owners and elevator contractors. RE/
