Hello,

I am looking for some Otis escalator 506 prints vintage 1992ish. I would also like to know what the naming and identification of the components are.

The unit I am working on has been messed with over the years. I think some of the contactors are wrong. Weirdly I have 24vac contactors and 24vdc contactors fed from the same supply (24vac).

The prints I have are hard to read and are incomplete.

Thanks in advance,
Any help is appreciated👍
