Sadly for you, you don't get what you pay for, but you pay for what you get.
Yes you are way off base!
The city of Los Angeles inspectors assist you in being sure your elevator meets the MINIMUM code requirements required by the law as well as the rules and regulations.
Does the company you have have a contractors license or a certificate as a Competent Conveyence company?
Maybe you should make a call to the IUEC local 18 and see if they are signatory.
The PLC is available from
http://www.automationdirect.com/adc/Home/Home?gclid=CJOK963K2c4CFYqCfgodc-sEFg100K for a new updated controller is what happens to people like you who are fooled into doing business with people who are in Los Angeles and do not speak your language. Stop being a victim and do the right thing.
You are sadly misinformed about Los Angeles city code as well as Title 8 and it is foolish of you to believe your fears are founded in fact.
May I respectfully suggest you obtain a copy of California Code of Regulations Title 8
Division 1. Department of Industrial Relations
Chapter 4. Division of Industrial Safety
Subchapter 6. Elevator Safety Orders
Group 1. Administrative Regulations (Sections 3000 - 3009)
and look up the definitions of "repairs", "replacement" and alterations?
Do you have a permit for the controller you currently have?
Save yourself a ton of money and do it right the first time.
It is and will for ever be the building owner's responsibility.
As the owner's agent you have a duty to inform them. Do so with out delay.
